47.141.37.161: No

Did this example actually happen? [[Special:Contributions/47.151.65.120|47.151.65.120]] 04:33, 23 June 2026 (UTC)

This comic reminds me of [[1122: Electoral Precedent]] and [[2383: Electoral Precedent 2020]]. Generalizing coincidences.

I am not a native English speaker. What does " they've gone 0 for 2" mean? Obviously it cannot be the score, since they are already leading 2-1? Or does this refer to a previous match?
And on a more general note, I am really surprised to discover the second football themed comic strip in a few days. OK it's the World Cup, but I always thought that Randall doesn't really care about sports? --[[Special:Contributions/92.209.171.90|92.209.171.90]] 08:37, 23 June 2026 (UTC)
:I ''am'' a native English speaker, but it was also a bit impenetrable to me. In part, perhaps, because it was ''intended'' to sound impenetrable (as part of the joke). But, even if not, it may be because it's using Americanized sports-talk phrasing that just isn't (yet!) used so much in my more native Anglicised commentaries that I'm used to.
:However, I ''think'' they're saying that "in the two specific occasions in which all those other conditions occur, they won in neither of them".
:A simpler version being perhaps to state that a given team/player has gone nought-for-two in previous matches with their current opponent(s). The results of those contests might have been anything (the winner having gone to 3-2 after penalties, 6-love/6-love/6-love, a par-4 advantage or getting them all out for 178 — depending upon the sport), it's just the win/lose (or win/not-win) count thats "0 for 2".
:But this is a case of Overly Narrow Superlative (overlapping with P-Hacking), making it a dubious analysis. Starting with ignoring all the games there are in which a given svoreline was not achieved in a particular ''minute'' of play. I think part of this set-up is the difference between Gridiron 'football'/"hand-egg" having tons of points scored, whereas this football (Soccer) often turns on comparatively low scores that (one-nil can be a worthy and entertaining win/loss, and even a no-score-draw might have been fun to watch if your side isn't in desperate need for a win). These commentators, or at least the US audience they're commentating to, are used to spieling things about "the last time they were down on the forty-yard line in the fifth quarter, with two home runs and a shot from the free-throw line in hand..." (look, I {{tvtropes|GretzkyHasTheBall|know I don't know}} what they'd really say, to any accuracy, there was no point even trying!), at least to fill in the copious down-time/time-out pauses. (Which isn't actually as easy with low-scoring but more ever-moving 'soccer', where there's often much to be said about current player and ball movements almost all the time; although a five-day international cricket test match(!) commentary on the radio ''does'' rather famously lapse into 'filler' like discussing the nice cake that was sent to them by a listener, in the gaps between balls being bowled...)
:Sorry, that was a long and convoluted paragraph. (But then, so was the Explanation, before I decided to say this down here. I hope it's been tweaked since then. I'm only really guessing about the Leftpondian commentator-speak being parodied here, and ball-sports aren't really my main interest in the sprorting sphere itself. (But, regarding balls that aren't themselves spheres, I'd happily discuss Rugby League or Rugby Union, and why they're 'better'... though I would totally acknowledge Aussie Rules as a class of its own as far as such contact-sports go.)

:I don't know what prompted the rant above, but if you don't care to read it, "going 0 for 2" means having 0 successes out of 2 chances. In the context of this commentary, it's referring to winning 0 games out of the 2 games that meet the criteria. It's not intended to sound impenetrable; it's a common phrasing.[[Special:Contributions/163.116.145.33|163.116.145.33]] 13:37, 23 June 2026 (UTC)
::Worth noting I think that it's a common AMERICAN phrasing. It's hardly ever used in England.
::I don't know what prompted you to think it was a rant. It's certainly quite lengthy (in the context of discussion comments here - not in the grand scheme of things), but that's not really the definition of a rant. [[Special:Contributions/82.13.184.33|82.13.184.33]] 14:57, 23 June 2026 (UTC)
:::Because it was lengthy, but it almost entirely ignored the question, focusing instead on your opinion on sports and their commentary styles. Going off on one vs. ranting...it's a blurry distinction. You absolutely did the former; possibly the latter. 0 for 2 (pronounced as a letter "O") simply means zero victories for two games played. It's not obscure terminology. [[User:Yorkshire Pudding|Yorkshire Pudding]] ([[User talk:Yorkshire Pudding|talk]]) 15:50, 23 June 2026 (UTC)
::::Yes, it is obscure. The only context in which “0 for 2” makes sense to me is in cricket: 0 runs scored, 2 batsmen out. The 0 of / out of / from 2 described above is just not something which would occur to me, and it's largely because of that ‘for’. If it's common, why have I never heard it on (for example) ''Match of the Day''? [[User:Randomnonsense|Randomnonsense]] ([[User talk:Randomnonsense|talk]]) 16:44, 23 June 2026 (UTC)

:::Precisely what Yorkshire Pudding said; you could have stopped after your third paragraph, or really even after your second, and you wouldn't have lost any relevant information. I'll add that the rantiness is enhanced by saying things like Gridiron 'football'/"hand-egg", and the very "sportsball"-coded "the last time they were down on the forty-yard line in the fifth quarter, with two home runs and a shot from the free-throw line in hand...," which, apart from their irrelevance to the topic, have a very superior air.

Closest match I can find is Germany - Curacao but there Germany took the lead in the 38th minute (not the 37th). I leave the deep dive on Germany's record against teams alphabetically before them when they have taken the lead 2-1 in the 37th/38th minute to someone else...
: And, of course, Germany destroyed Curaçao 7-1, just like they did to Brazil (which is also alphabetically before Germany!) 12 years prior [[User:Wilh3lm|Wilh3lm]] ([[User talk:Wilh3lm|talk]]) 12:38, 23 June 2026 (UTC)
:: As I recall, the Germans had already scored 7 before the Brazilians scored, and quite a few people independently came up with Ger-many Braz-nil… [[User:Randomnonsense|Randomnonsense]] ([[User talk:Randomnonsense|talk]]) 16:48, 23 June 2026 (UTC)
::: I did a ''limited'' look into possible edge-cases, but didn't get anywhere so far as to confirm all minutes-of-goals for those. Concentrated on (fairly recent) games with more than a 2-2 final score, as the requirements are that they must have at least been 2-1 and then ''at least'' got levelled up by the lagging side, before the possible tie-breaking penality shootouts.
::: I suppose I could have first narrowed it down to every game with a reported 37th minute goal (given the rarity of that exact event, by apparently common agreement) ''then'' tallying up the precise game-state at that time, plus the final result. But I was looking into the other fine details first. [[Special:Contributions/81.179.200.152|81.179.200.152]] 23:14, 23 June 2026 (UTC)

'''Don't assume "bad" p-hacking without looking closer at the data''': Sometimes what looks like P-hacking is really finding previously-unseen patterns. If you have a drug trial on a drug that you have no reason to think will show gender differences and you are asking "is this drug better than existing drugs" and the results are inconclusive, then you do "p-hack" subgroups and find that in males between the ages of 18 and 50 it demonstrates superior results, you MAY be cherry-picking results or you MAY have found a hidden pattern. Assuming your sub-group size isn't ridiculously small, you can legitimately claim that you need more funding for a follow-up study or at least a follow-up analysis of this subgroup in previous studies of the same drug. [[Special:Contributions/150.221.155.241|150.221.155.241]] 13:35, 23 June 2026 (UTC)
:Yes, more data is usually the solution. The comic deliberately uses an extremely small dataset. You can make up almost any hypothesis and find 2-3 datapoints that fit it. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 14:24, 23 June 2026 (UTC)
::Or, perhaps more commonly, if you have a sufficiently large dataset you can mine through it and come up with two or three interesting-looking 'hypotheses' that it'll appear to support, even if you didn't have any to start with. [[Special:Contributions/82.13.184.33|82.13.184.33]] 15:02, 23 June 2026 (UTC)
:::The difference is that taking a lot of data and looking at many possible patterns to that data is likely to reveal artefacts of mere chance.
:::Considering a single possible pattern and looking to see if it is justified is (even if, as an individual pattern, exactly as much a coincidental artefact or not) useful. So one might legitimately be able to suggest that the male subjects may show a legitimate long-term improvement to a treatment (possibly either because it works better with male hormones, or because there aren't the same underlying hormonal variations across each month, or just because it works better for different body-mass/fat distributions that are more typically male than female), or perhaps vice-versa (that it actually works more usefully for females, again for such reasons).
:::But filtering inconclusive results through many possible sorting algorithms and extracting 'nuggets' of apparent significance devalues those nuggets. Especially if it gets more complexly combinatorial. Imagine the number of criteria you might have considered, together and individually, to establish anything like "the treatment was twice as effective as the control treatment in males less than 30 with an older brother and females over 38 whose job is in education". How you'd even rationalise/explain such a complicated cause/effect relationship is one thing. That you've probably discarded so many other datums you had (out of hundred subjects, you're decided to ignore maybe half the people because of being under-/over-age, in this gendered thing, cutting back ''far'' more than that for the family/employment requirements and then of the remainder (probably somewhat <10, I'd guess, depending on where you actually got the initial subject-pool) and then, for such a comparison to stand up, the non-discards must be further split between on-treatment and whatever off-treatment/old-treatment you're comparing to, is an issue of practicality which is the other issue. (At least until you come up with a decent reason to recruit these subsets explicitly for a follow-up study, assuming the relationship doesn't just vanish/revert-to-the-mean when you do as it was pure chance after all.)
:::Realistically, you should weight the apparent significance of 'results' according to how many results you actively looked for. (e.g. had fifty possible things, divide the significance of any positive 'match' by 50. Although I can see reasons why division by 50**2 ''or'' ln(50) would be better, depending upon the scenario relevant to this kind of siftingt.) But better just to avoid that.
:::Which might be a big problem in AI-derived research results. You're asking an algorithm to make an ''uncounted'' large number of separate interpretations (including of exactly what question it is that you're asking) and then it's returning the 'nicest' results that seemingly fulfil its mysterious 'training' insofar as they aim to be the single/several results from the largely randomised treatments that are judged to be the least incomprehensible.

The saddest part of all this is that Randall, in the title text of this comic, might be one of the last persons in the English-speaking world to recognize that "data" is a plural noun, the singular of which (icymi) is "datum". [[Special:Contributions/147.81.27.244|147.81.27.244]] 15:38, 23 June 2026 (UTC)
:The Latin word "data" is a plural now, but the English word "data" is [+ sing/pl verb], and in most writing is used as a plural. It's really only used as a singular in scientific and technical contexts. Borrowed English words don't follow Latin rules, and "data" is not alone in this. Meetings have an agenda, even though in Latin an agenda is many agendum. https://www.merriam-webster.com/grammar/some-data-about-datum. --[[Special:Contributions/49.255.140.250|49.255.140.250]] 01:38, 24 June 2026 (UTC)

I just wanted to add that the [http://forums.xkcd.com/viewtopic.php?f=7&t=74111 forum post about this comic] notes that this comic was accidentally posted by the site admins for xkcd, then later replaced with the current version of the comic, i.e. [[940: Oversight]]. The direct image URL for this comic now points to [https://imgs.xkcd.com/comics/five_minute_comics_part_4.png this image]. Thus, the comic was not published through the unofficial xkcd app or anything like that; the more likely scenario is that the app downloaded the comic when it became available and cached it, so when the comic was replaced with [[940: Oversight]], the app did not update it.

3031: Time Capsule Instructions

2026-06-02T03:00:11Z

47.141.37.161: /* Potential solutions */ if there was a bobcat in there it would be dead

{{comic
| number = 3031
| date = December 30, 2024
| title = Time Capsule Instructions
| image = time_capsule_instructions_2x.png
| imagesize = 692x235px

}}

==Explanation==

This [[:Category:New Year|New Year comic]] sees a New Year party held at a location where a {{w|time capsule}} has clearly been buried, as evidenced by a sign marking the spot. It is likely that this was buried some years ago with the intention of being unearthed at the start of 2025, after some significant number of years have passed, rather than for an indeterminate amount of time (such as was the case in [[1617: Time Capsule]]), with the intent to allow people of a then-future time see what those of that era found interesting to preserve and "send" into the future.

Some form of New Year Celebration is happening near to the Time Capsule site, as indicated by the off-panel noises, probably especially convened at the capsule's site in eager anticipation. [[Cueball]] and [[Megan]], who have already said cheers with their wine glasses, look eagerly on when [[Ponytail]] opens the time capsule.

Not all such projects are kept conspicuously marked, or may lose their signage due to circumstances unanticipated at the time of the original installation, resulting in a surprise (or accidental) unearthing, while others may still be known for what they are (as with the intended time to stay closed) but need to be relocated/reconcealed due to later redevelopment of the location. (There is generally nothing to prevent premature unearthing and opening, perhaps especially to ensure that the contents are not damaged, but often {{w|Blue Peter#Time capsules|efforts are taken}} to best adhere to the original wishes.) To this end, as might be expected of such a time capsule, the box that Ponytail digs out is itself marked that it must not be opened until the year 2025 and it seems that (for the comic) this is the case, and at least part of the reason for the gathering.

Within the capsule, however, is a second container (a not atypical precaution), but this one has the instruction to not open after 2024, which is a far less obvious element for a time capsule (though various supplies, from [[2178: Expiration Date High Score|packaged food]] to [[2297: Use or Discard By|signal flares]], may have a similar requirement). Obeying the instruction for opening the first box has entirely precluded obeying that given as a prerequisite for opening the second... at least without using some form of time-travel. This could be either be a mundane twist of the circumstances (changing reference calendars or time-zones), or else require actual time-travel, but it is unlikely that they have [[1203: Time Machines|any practical solution]] prepared to use to overcome this twist.

The title text makes the situation more similar to {{w|Matryoshka dolls}}, where boxes are recursively stacked, with a third label having another restriction. This new label alludes to one of the ways one can open the first two boxes without ignoring the instructions: by crossing time zones. When more easterly-referenced locations have become the 1st of January 2025, it will (for a short while) still be the 31st of December 2024 in more westerly ones (the boundaries themselves might be any orientation, not just north-south; the whole concept inverts across the International Date Line, before even considering hour-shift differences), meaning that theoretically someone could open the first box in a time zone where it is 2025 and then quickly travel to one in which it is still 2024 to open the second box. Depending upon where the capsule was located, timely travel opportunities ''may'' be possible, but it seems unlikely to have been something anticipated by the recipients of the task.

However, the title text implies that if you take advantage of this loophole, you will not then be allowed to open a third box inside the second box, as the instructions for ''that'' box requires that you have opened the first two boxes in the same time zone. You must not open the third (and final?) container unless you opened both previous boxes in the same time zone as you are now, which is not compatible with having changed location to get to this point.

===Potential solutions===

Depending on interpretation, you could defeat the third box by placing it inside two time zones at once before opening it, as there is no time limit on the third box. This works if the instruction on the box is read as "unless you are in the time zone where you opened the first box, and you are in the time zone where you opened the second box". However, this new loophole could be patched by interpreting the third box as "unless you are in the ''one'' time zone where...".

How to be considered to be simultaneously covered by two time-zones (in a way that you can [[2846: Daylight Saving Choice|choose which to observe]]) is left up to the reader, although another variation of this solution would be to change the calendar used as point of reference, as {{w|Calendar era|many calendars}} use a lower year than the Gregorian calendar, or is [https://www.bbc.co.uk/news/articles/crl3grgg9zeo offset by a few days], and you could justify changing the date (if not the hour) that you consider true. Or perhaps mix and match calendar traditions that consider a day (and therefore a calendar date) to start only at dawn, rather than at astronomical/geopolitical midnight.

Perhaps the solution would be for both the box and the person opening it to be on the boundary between two time zones, half in each. Or, depending on how one interprets the nature of Daylight Saving Time, there may be another solution. In Australia, {{w|Northern Territory}} and {{w|South Australia}} are in the same time zone (by the most common interpretation of the word) and border each other, but only the latter uses Daylight Saving Time; similarly, {{w|Queensland}} does not use Daylight Saving Time but is in the same time zone (by the most common interpretation of the word) as multiple Australian territories that do use Daylight Saving Time, including {{w|New South Wales}}, with which Queensland shares a border. This suggests the idea of opening the first box in South Australia or New South Wales then taking it north of the (latitudinal) DST boundary without crossing any (longitudinal) time zone boundaries; one will then have up to an hour to open the second box and then as long as one wants to open the third box. However, Randall [[:Category:Daylight saving time|has historically expressed opposition to Daylight Saving Time]], so he might not count the first opening as occurring in 2025 if that year has already started only by virtue of Daylight Saving Time.

Without any tricksy thinking and assuming we may not have the box nor the person opening the box in two time zones at the same time, a semantic loophole presents itself. The title text refers to "you" and not the box, while the instructions on the first and seconds boxes can be reasonably assumed to apply only to the time zone that the box itself is in. The box could be moved from one time zone to the other by the use of, as an example, a robotic arm, then opened, and then brought to the time zone that the person controlling the robotic arms is in. Alternatively, if two different people opened the first two boxes in the respective time zones, the "you" would then have to be reconsidered as plural, and, since both people could stay in their respective time zones, the third box could be opened.

Some of the above solutions might only be used if you already knew of the instructions on the boxes, unless it was previously dug into one of the relevant locations (and, depending upon the 'author' of the box-puzzle, this may have also been anticipated and be an intended part of the puzzle). Even getting the second box open following instructions would require it was possible to travel fast enough and far enough to reach a second New Year, which is not easily guaranteeable on the spur of the moment. This is definitely possible if you plan for it, but whether this disinterment party was prepared is unlikely.

Having made the initial two openings in different locations, another possibility is to choose either location (it being easiest to remain where you were allowed to open the second box) and having removed all boxes from any prior host containers, close the box that is now out-of-zone. You can now either take the box's mandate as dealt with, and expired, or avoid any quibbles by waiting just long enough for the now-closed 2025 box to once more experience 2025 in the second box's locale, permiting you to re-open it and fulfil the requirements of the third.

In any case it seems more likely that normal people, having taken the initial instruction at its word, would ignore any new [[2841: Sign Combo|contradictory rules]]. The original rule that the Time Capsule should remain closed until 2025 is the one that makes sense. So after opening the first at the right time, one could just disregard the words on the boxes (or at least Randall's interpretation of them); there is probably not some kind of [[242: The Difference|magical enforcement mechanism]]. Also it seems likely this was just a prank so there will be nothing interesting inside, but one might fear some kind of booby trap. So there could be some kind of enforcement mechanism.

Considering when the comic was published, however, a full day prior to ''any'' territory having actually celebrated the arrival of 2025, one might imagine that this is ''not'' an upcoming scenario, but one that has happened/is happening already. In this case, it suggests that the party (both diggers-up and associated party-goers) were fully aware of some of the stipulations they were to be subject to and (impatiently, or at even just as cleverly as the initial burier of the boxes) arbitrarily marked the arrival of 2025 ''early'' to 'justify' the opening the outer box. They could then conveniently reconsider their schedule, continuing now on the basis of acting prior to the end of 2024, and have no further trouble with either of the inner instructions (opening the next box before the ''official'' arrival of 2025 would be simplicity, and any antecedent calendar reinterpretations could be considered logically separated from any prohibitive change in location and/or time-zone).

There is also the question of a hypothetical fourth box, which, given that there was a third box, there is no reason that there shouldn't be a fourth, probably with a label designed to better shut down some of these potential solutions. And maybe it's [[1557: Ozymandias|boxes all the way down]]!

This is a comic in the [[:Category:My Hobby|My Hobby]] series, this time the hobby of reverse-engineering original units from oddly specific measurements in another unit. Unlike in many of the My Hobby cartoons, where Cueball's hobby is something eccentric or prankish, in this situation he uses his hobby simply to understand the origin of someone else's unusual phrasing. A fathom is a unit of measurement used to measure how deep water is. One fathom is equal to six feet.

100 fathoms is actually 182.88 meters, however as the title text explains, they rounded down in order to prevent a possibly incorrect statement.

For those curious, an aircraft with one pair of wings is the aerodynamic equivalent of one pair of legs or wheels. It can work, but it requires careful considerations to keep it balanced. If a conventional aircraft loses its horizontal stabilizer, it will lose that balance and nose up or down uncontrollably. Aircraft that have no horizontal stabilizer usually use a method in which part of the main wing effectively functions in its place.

Could it be that the boat inside the bottle is the one talking, not Beret Guy? [[User:SovereignFinn|SovereignFinn]]

Off-screen, they are all in an even larger bottle. [[User:Fephisto|Fephisto]] ([[User talk:Fephisto|talk]]) 16:46, 2 May 2026 (UTC)

I see a totally different context and joke here: the water level in the bottle is lower than the water level outside. (Which requires a bit of physics thinking to figure out why this would be so.) At first intuitive glance, the water levels should be the same, hence, as the title text says "... seems impossible ...". Then the title text offers a (wrong, but intuitive) explanation for the different water levels: he entered the bottle at very young age when he was lighter (equal levels). Now as an adult he is heavier, thus the whole bottle is heavier and hence it is dipping deeper into the outer water (creating different levels).
[[Special:Contributions/31.16.254.255|31.16.254.255]] 20:38, 1 May 2026 (UTC)
:I think it's sort of what would happen with a glass bottle. Glass is far more dense than water. If you part-filled a bottle (sideways, supported) so that it is level with the water it is sitting in and then plug it and release it, the air-filled bottle would then sit lower in the water than its previously established level.
:i.e. the trapped water itself is neutral, versus the volume of external water that it displaces. The bottle-material that is below that level is denser than the water ''it'' directly displaces, so is negatively buoyant (and the above-the-water glass is less buoyant than the external air). It needs to sink enough that the internal air is also contributing to the displacement of the whole sealed bottle enough to equalise the whole thing.
:''And'', the marvelous thing is that the bottled boat itself is completely neutral. As it's floating at a level that is neutrally buoyant across the (internal) water+air interface, so long as it is floating, thus the whole container weighs (as well as displaces) the same, for any given internal water-level. (i.e. how {{w|boat lift}}s operate... two 'troughs' that essentially weight the same regardless of whether they have a boat in them, that can be hauled up and down essentially perfectly counterbalanced by the paired trough going in the opposite direction. Which I still think is rather clever.) [[Special:Contributions/81.179.199.253|81.179.199.253]] 21:36, 1 May 2026 (UTC)

Hi, new here, thanks for explainxkcd. Not sure about this sentence: "The weight of the missing water in the bottle is consequently equal to the weight of the bottle, the boat, and Beret Guy." I think the weight of the missing water is actually a bit less than the weight of the bottle. Here's the reasoning. First, imagine a bottle containing only water, no boat. We know that the weight of the displaced water equals the weight of the empty bottle plus the water inside (m_wd = m_b + m_wi, dropping earth gravity on both sides). And we know that the volume of the displaced water equals the volume of the bottle walls underwater plus the volume of the water inside plus the volume of the missing water (V_wd = V_bu + V_wi + V_wm). Multiply the latter by the density of water to get m_wd = rho_w * V_bu + m_wi + m_wm, and set equal to the first equation to get m_b + m_wi = rho_w * V_bu + m_wi + m_wm, or: m_wm = m_b - rho_w * V_bu. In other words, the mass of the missing water equals the mass of the bottle minus the mass of water with the same volume as the submerged parts of the bottle walls.
Second, we can now take water out of the bottle with the same mass as the boat and Beret Guy, and put in the boat and Beret guy. The water level inside the bottle will not change (as the amount of water displaced by boat and Beret guy is just the amount we took out). If the water level doesn't change when we insert boat and Beret Guy, the amount of missing water remains unaffected. In conclusion, the weight of the missing water in the bottle is a bit less than the empty weight of the bottle. More precisely, the volume of the missing water equals the volume of an amount of water with the same mass as the empty bottle, but reduced by the volume of the submerged bottle walls. Or not? Cheers, Fab [[Special:Contributions/203.218.42.181|203.218.42.181]] 08:07, 2 May 2026 (UTC)
:Did not see this until I (just) addressed that statement my own way. Slightly messily, but also trying to consciously remove BG+Boat from the basic equation (at least until the bottle is so filled that it starts pushing up on the bottle/the bottle pushed down on it, and BG needs to hope it had enough closed-cell buoyancy to not suffer too much from being flooded).
:The internal water-level (the boat's 'plimsol line', flattening out the 'wavy nature' of the water) is effectively constant (for a given similar 'plimsol line' of the bottle w.r.t. to the open sea), regardless of whether the boat is there. The weight of water that the Boat+BG displaces (plus also the weight of the air), by being there, is the total weight of the Boat+BG. Without B+BG, but the same water level, the water and air volumes that fit into the appropriate gaps (no 'bottle half empty'-type trickery allowed!) provides the same weight and volume.
:So, to calculate the bottle-weight ''minus'' the weight of the water(+air) that the substance of the bottle-body (and cork!) already displaces, imagine the boat isn't there and 'weigh out' the water that would be there in the 'slice' between the two surfaces, within the bottle (as if the boat was not there, everything else the same). Then go back and find the volume of the total bottle-glass, consider that in terms of water-density (''almost'' as accurate as accounting for which slices are to be given water-density equivalence, and which are to be 'converted' to air). Add that bottle-body water-weight to the surface-gap water-weight, and this equals the bottle(+stopper) weight, with Boat+BG not being a factor (so long as it is not at all grounded and/or 'ceilinged', within the bottle).
:I'm sure with a bit of calculus, we could do the whole thing. Calculating the volume of rotation of the hollow-bottle-shape, assuming a degree of cylindricality of profile, and integrating the 'sideways slice of semi-cylindrical contents' that exists between the two nominal surface-planes (reducing the 'peak and trough' water profile to equivalent flatness-level, especially considering that this involves the intersection of surfaces sloping/curving in multiple directions, might be the most hand-'wavy' part of the estimation, that's trickiest to be sure about) is left as an excercise to anyone sufficiently nerd-sniped enough to actually plug numbers into this. But the ''concept'', at least, seems 'simple' enough.
:And it shows that Randall didn't lazily draw the same water levels through both. Though there are arguments that they need to be different, in order to emphasise the full isolation of the bottle interior from the open sea, it could also have been done with a ''higher'' internal water level than the outside (implying the bottle-material was significantly less dense than water, or even that it's an 'air gap' between two line-thick 'skins', or maybe that the 'air' in the bottle is hydrogen, helium and/or lower-pressure than outside or...). I choose to believe that Randall (without necessarily enumerating the degree of the effect) chose a 'realistic' outcome of a floating bottle with a small amount of water in its 'bilgewash' bottom. (Saving that the natural attitude of such a bottle is either neck-up or neck-down, but then {{tvtropes|RealityIsUnrealistic}}. Or at least less visually aesthetic.)
:In fact, my only true concern ''is'' the attitude of the bottle. Sideways, as it is, smaller-BG could not have (as implied) sailed the smaller-boat into the neck, as it is now. Either there was more water originally (pumped out before BG then pulled the cork-stopper into place, or (knowing BG), he just drank it and... somehow, and without affecting his admitedly rather ambiguous personal density too much... 'retains' it all, still), or the bottle was tilted down at an angle (''not'' vertical!) and he floated 'up and in' before/during the twist in which the bottle underwent its current 'leveling sideways' orientation.

;Hover text
Is the hovertext also a potential reference to animals that get stuck within a particular location as they grow? I'm thinking hermit crab, but this might be an imagining. [[User:Kev|Kev]] ([[User talk:Kev|talk]]) 14:58, 2 May 2026 (UTC)
:Hermit crabs ''don't'' get stuck in one location, as they grow, though. They go and find a suitably-sized 'upgrade' of shell (or useful piece of seafloor rubbish, if they find one of those that they like the look of), either unclaimed or about to be vacated by a larger crab who is lining up their own 'upgrade' (often as a chain of such stepwise upgrades).
:At most, I'd expect it to be like "caught their neck in beer-can packaging, when young, get slowly strangled/garotted to death as they grow up with it still around their neck", rather than anything else. Some tree-hole nesting birds get effectively sealed in by closing the hole up with mud until it's more predwtator-proof, leaving only enough hole for their mate to give them/the eventual chicks bits of food (and chuck out waste), and no doubt creatures (like livestock) have escaped certain fenced/naturally-barriered areas when small and later couldn't get back through the gap if they tried to. And queen-insects of various kinds might be practically confined to the nests/hives in their fully developed 'egg-laying machine' form. But nothing that seems (to me) to have been directly or tangentially alluded to, to be honest. Though I might be missing something (other than already noted pears, and similar "bottled on the tree" novelty versions of such things).

: It's a joke about battery-operated tools. If you buy a battery-operated drill from Milwaukee, it probably does not come with a (removable) battery and charger. So you buy the battery and charger, which are probably comparable to the cost of the tool. Now, when you need a battery operated saw, you already have the battery and charger from Milwaukee (which will work with the saw), so you buy the Milwaukee saw. And the Milwaukee blower. And the Milwaukee weed-whacker. Etc, etc. Buying one brand of battery operated tools locks you into that ecosystem, to a certain extent. Which means you wind up agonizing over which brand has the better overall ecosystem, even though all you need right now is a drill.

::Sorry, no. Many Milwaukee and Black and Decker(etc)tools DO come with batteries and chargers!!! The point is to get the buyers into the "ecosystem", so future purchases that use the same battery system will be more appealing. For this purpose, providing the charger and one battery, at least for the larger, more popular products, makes perfect sense. The more specialized tools, the smaller accessories might not have them, but they are practical purchases once someone already owns a charger and at least one interchangeable battery. For Milwaukee in particular, the M12 FUEL 1/2 Drill Driver, the M18 FUEL Oscillating Multi-Tool, the MX FUEL Backpack Blower and M18 FUEL 15 Gauge Finish Nailer all include battery and charger. Sorry for this tangent, but I don't think it the joke is about batteries! After all, none of the SIMPLE tools needs a battery. It's about committing to a brand, in a broader sense.

3235: Types of Board Game

2026-04-21T06:00:40Z

==Explanation==
{{incomplete|This page was created by a member of the Congress of Vienna in 1814. Don't remove this notice too soon.}}

This comic is about types of board games.

{| class="wikitable"
| Boring || This is a very simplistic and boring board game style, where the players simply move around the board aimlessly. The simplest forms of these games, such as {{w|Candy Land}} or {{w|Snakes and ladders}}, require no decision-making at all, with players simply moving as the dice or cards direct them. Notably, this board game does not have an end goal such as "reach the end", and runs until everyone decides to stop playing with no winners or losers.
|-
| Abstract || This board game has more abstract tones, with less of a tangible goal.
|-
| Hyperspecific Theme || This board game takes place on a specific date and time, and appears to have little room for flexibility. The {{w|Congress of Vienna}} was a gathering of diplomats from many different countries at the end of the Napoleonic Wars. There exists an actual board game about the Congress of Vienna, see https://boardgamegeek.com/boardgame/296578/congress-of-vienna, but it has nothing to do with lighting candles.
|-
| Overcomplicated || Twilight Imperium is a fairly complicated board game (complexity rating 3.46 / 5 on BoardGameGeek.com). Cones of Dunshire is a joke board game that was shown on the TV show ''Parks & Recreation''. Combining them would be extremely strange.
|-
| Cooperative || Cooperative board games center around players attempting to reach a common goal, winning or losing together. Many feature impediments to communication that make this more difficult; for instance, players may have secret cards they are unable to reveal before playing, or be restricted from saying certain words. The game in this panel appears to forbid all communication between players except for hand gestures. The punch line likens it to a very mundane activity, sorting a junk drawer, made artificially more difficult due to silence, and suggests the game is just as boring.
|-
| Branded || Some board games are published and marketed as tie-ins to other forms of media, using settings, characters, or events from the source to appeal to its fans. The theming often has little to nothing to do with the gameplay, as the many branded variants on Monopoly can attest. The game in this panel is themed after the sitcom {{w|Friends}}, with the unlikely addition of Son Goku from {{w|Dragon Ball Z}}.
|-
| Party || Various board games intended for adults have swearing in them, one of the well known examples being {{w|Cards Against Humanity}}, which is known for its rather vulgar language at times.
|-
| Social Deduction || {{w|Social_deduction_game|Social deduction games}} revolve around the players attempting to deduce the roles or allegiances of other players, based both on special abilities provided by the game and the players' native abilities to tell which of their fellow players are being dishonest. Commonly, they involve an 'uninformed majority,' who do not know the allegiances of other players, attempting to discover the 'informed minority,' who know the members of their team. The minority is often framed as 'evil,' with the ability to 'kill' other players and remove them from the game; their victory condition often revolves around killing most or all of the 'good' players. The game in this panel revolves around finding a 'secret murderer,' but evidently has required clarification that discovering a ''real'' murderer does not count, implying that one or more of the participants has actually killed someone in real life.

2929: Good and Bad Ideas

2026-03-28T06:17:34Z

| titletext = While it seemed like a fun prank at the time, I realize my prank fire extinguishers full of leaded gasoline were a mistake.
}}

==Explanation==
This is a scatter plot comparing how good an idea sounds to how good the idea is. For example, leaded gasoline sounded like a good idea due to its anti-knocking effects, but is a bad idea due to lead toxicity. Fake prank fire extinguishers both sound bad and ''are'' bad, as they can make a dangerous situation worse. Putting mold on infections sounds like a bad idea, but some molds, like ones containing penicillin, have helpful antibiotic effects.

The title text combines leaded gasoline and a fake prank fire extinguisher into something worse than either. The fire extinguisher is fake and releases flammable material onto the fire, and there is additional lead toxicity.

In essence, it artificially raises the {{w|octane rating}} of the fuel, reducing the need for fuel refinement, thus reducing waste and/or expense. Lead, however, is both toxic and bioaccumulative, meaning that lead released into the air over decades built up to harmful levels in people (as well as other animals) and almost certainly contributed to a host of health issues. Some scientists even hypothesise that {{w|Lead–crime hypothesis|crime levels are influenced by lead exposure}}. (It should be noted that this only "[sounded] like a good idea" due to deliberate campaigns to obscure the known dangers).

Despite this long history, the notion that bleeding someone is bad now seems like basic common sense, and it's now well-understood that blood-letting (outside of {{what if|98|certain rare and specific cases}}) does no good, causes significant harm and quite certainly causes many deaths.

|Extension cords with prongs on both ends||Should allow easy connection between 2 female connectors||data-sort-value="+5%"|~0%||data-sort-value="-80%"|-80%||Prongs on both ends would make it easier to plug the extension cord in on either side. But once plugged into an outlet, the other end becomes a serious shock hazard, as seen in [https://www.youtube.com/watch?v=L08LjkN1k70 this Backyard Scientist video]. Short circuits (both ends connected to outlets supplying power) would be much more likely, resulting in more sparks, fires and damage to wiring. Double-ended cords are also sometimes used as an especially dangerous way to feed power from a generator into an outlet, introducing a shock hazard to any utility workers attempting to restore power.

|Fake prank fire extinguishers||A “fake prank” fire extinguisher would be something that appears to be a prank fire extinguisher, but is actually a real fire extinguisher.

Intentionally placing empty or otherwise non-functional {{w|fire extinguisher|fire extinguishers}} as a {{w|practical joke}}.||data-sort-value="-105%"|-100%||data-sort-value="-85%"|-85%|| The idea of placing fake fire extinguishers as a prank, presumably so that a person who thinks they are grabbing a real fire extinguisher will instead find a decoy, sounds, and indeed would be, very dangerous and potentially life-threatening for many people. In the United States, (and presumably most countries), this would also be a felony in most, if not all, jurisdictions. This exact scenario was depicted in the 2001/Season 3 Christmas episode of Family Guy, where Brian failed to put out a fire because the fire extinguisher shot fake snakes instead, acting as further fuel to the fire. An example of a similar situation, although not intended as a prank, can be found [https://twitter.com/ThatSamWinkler/status/1657154071051239424 here].
The title text expands this idea by having the prank fire extinguishers filled with (leaded) gasoline. This is literally adding fuel to the fire.

However, such vehicles would require power storage (due to power requirements, weather conditions, shade from roadside features and nighttime driving), adding significant weight. Adding solar panels to a plug-in or hybrid vehicle would add cost, weight, manufacturing complexity and maintenance requirements. Solar panels on moving cars are less efficient than in stationary installations, where they can be aimed at the Sun, and subject to damage from both collisions and road debris; even without these problems, the size of automobiles relative to their power requirements would sharply limit the car's range (unless it was a normal electric vehicle with supplemental solar panels). Solar cars do exist (the {{w|World Solar Challenge}} is a competition for such cars), but as a practical form of transportation, the negatives likely outweigh the positives.

But there are several pitfalls. Spin-offs of a popular property are often low-quality cash grabs. Prequels, specifically, are constrained by the fact that they have to lead to the story that's already been released, which can lead to contrived storytelling. There's less room for suspense, since the future of the storyline has already been established. There's a tendency to invent or fill in detailed backstories, which can undermine character arcs and/or destroy the mystery and nuance of certain characters. And, since they tend only to be made where the original is already well-received, regression to the mean tends to mean they are more likely than not to fail to live up to expectations. Prequels can be good, but there are a lot of ways they can go wrong.

|Transitions® lenses||A brand name for {{w|Photochromic_lens|photochromic lenses}} in glasses or contacts, which get darker (like sunglasses) in bright light.||data-sort-value="+30%"|30%||data-sort-value="-20%"|-20%||Photochromic lenses are clear lenses that darken when exposed to UV light, then turn clear again when the UV is removed. The advantage is that wearers of glasses don't need to have separate (prescription) sunglasses or contacts. However, the process is relatively slow (about a minute) so not so useful when there is a quick succession of shade and bright light, as in a forest or when driving. If used in a car, the windscreen filters out UV light to some degree, which prevents the glasses from darkening as required. Finally, the process is temperature dependent, so in hot weather the glasses don't become as dark, and in cold weather they might stay dark for too long.

Additionally, the following should be considered. UV-conscious people protect their face against UV light, so the skin doesn't form wrinkles and ages slower. Sunscreen is difficult to apply around eyes without getting the substance on eyeballs (cosmetic substances should not get there{{Citation needed}}). One of the reasons behind wearing sunglasses may be to protect skin around eyes from forming so called crow's feet. Under UV-filtering sunglasses, UV-activated transitions contact lenses will not darken defeating their purpose. At the same time transitions contacts are typically at least twice as expensive as the regular ones.

|Cutting pizza in squares||Cutting (a presumably round) pizza in squares||data-sort-value="-25%"|-25%||data-sort-value="-20%"|-20%||Most people cut pizza into wedges and hold it by the crust. Cutting it into squares could allow for more pieces to be shared, if the resulting wedges would be too thin to be practical. However, pieces near the center will have no crust to hold it by, getting cheese and sauce all over your fingers. Cuts around the edge will probably leave smaller leftover scraps which are mostly crust. While hardly a disaster like the other items in its quadrant, square pizza pieces are just not very useful and rather inefficient. Cutting a rectangular pizza into squares might not suffer from the problems above, but, unless the pizza itself is square and cut only into four squares, some people will end up with a higher crust-to-topping ratio than others.

Instead, they move existing thermal energy from a coolable environment across to a warmable one. This allows a space to be heated with significantly less energy use than a furnace or resistance heater that generates heat directly from chemical or electrical energy. Because these units are usually operated by electricity, they can provide heating with renewable energy (potentially using {{w|thermal energy storage}} for load-shifting), reduce or eliminate the need for natural gas connections and prevent several risks that come with traditional furnaces (such a carbon monoxide leaks and fires). In addition, heat pumps can operate in the reverse direction as air conditioners, so a single unit can be designed to both heat and cool a building. It sounds like a good idea and works out better than expected in real life.
According to [https://www.technologyreview.com/2023/02/14/1068582/everything-you-need-to-know-about-heat-pumps/ MIT Technology review]:
<blockquote>Heat pumps today can reach 300% to 400% efficiency or even higher, meaning they’re putting out three to four times as much energy in the form of heat as they’re using in electricity. For a space heater, the theoretical maximum would be 100% efficiency, and the best models today reach around 95% efficiency.</blockquote>

A healthy microbiome can be destroyed by bad eating habits, unhealthy lifestyles, infections or the use of antibiotics. Sometimes it may be beneficial to completely sterilize the gut and then take a sample of a healthy biome from another person. A sample is enough, as the organisms will multiply. As long as the patient eats correctly, the microbiome after transplant should develop correctly.

It sounds bad because we tend to think of our feces as something gross, to be discarded, and other people's bacteria as infectious. It is called fecal transplant as our feces contain about 50% of gut bacteria, but nowadays the sample usually takes the form of a coated pill that is applied rectally.

2929: Good and Bad Ideas

}}

==Explanation==
This is a scatter plot comparing how good an idea sounds to how good the idea is. For example, leaded gasoline sounded like a good idea due to its anti-knocking effects, but is a bad idea due to lead toxicity. Fake prank fire extinguishers both sound bad and ''are'' bad, as they can make a dangerous situation worse. Putting mold on infections sounds like a bad idea, but some molds, like ones containing penicillin, have helpful antibiotic effects.

The title text combines leaded gasoline and a fake prank fire extinguisher into something worse than either. The fire extinguisher is fake and releases flammable material onto the fire, and there is additional lead toxicity.

! Idea !! What it means !! How good it sounds !! How good it actually is !! Explanation
|-
|{{w|Leaded gasoline}}||Adding {{w|Tetraethyllead|tetraethyl lead}} as an antiknocking agent to allow for increased performance||data-sort-value="+65%"|65%||data-sort-value="-95%"|-95%||Leaded gasoline was introduced in the early 1920s to allow higher pressures and temperatures in an engine without causing {{w|Engine_knocking|detonation (knocking)}}, allowing for increased fuel efficiency and engine performance; it also works to prevent engine valve wear. In essence, it artificially raises the {{w|octane rating}} of the fuel, reducing the need for fuel refinement, thus reducing waste and/or expense. Lead, however, is both toxic and bioaccumulative, meaning that lead released into the air over decades built up to harmful levels in people (as well as other animals) and almost certainly contributed to a host of health issues. Some scientists even hypothesise that {{w|Lead–crime hypothesis|crime levels are influenced by lead exposure}}. (It should be noted that this only "[sounded] like a good idea" due to deliberate campaigns to obscure the known dangers).
|-
|{{w|Bloodletting}}||Releasing "bad blood" from the veins||data-sort-value="-90%"|-90%||data-sort-value="-100%"|-100%||You need (most of) your blood. Losing [https://www.ncbi.nlm.nih.gov/books/NBK542273/ more than 15%] of a person's total blood volume results in adverse effects. Bloodletting was performed as a medical procedure for at least 2000 years until the 19th century. The idea was to withdraw blood to balance the body's "humors". Despite this long history, the notion that bleeding someone is bad now seems like basic common sense, and it's now well-understood that blood-letting (outside of {{what if|98|certain rare and specific cases}}) does no good, causes significant harm and quite certainly causes many deaths.
|-
|{{w|Asbestos}}||Mineral which does not burn, tolerates extremely high temperatures and forms small fibers. These qualities make it excellent for insulation and fire protection||data-sort-value="+90%"|90%||data-sort-value="-80%"|-80%||Asbestos was used extensively in ships and buildings throughout most of the 20th century. Unfortunately, the microscopic fibers that make up asbestos greatly increase the risk of {{w|Asbestosis|lung disease}} and cancer when inhaled, causing its use to be banned in most countries.
|-
|Extension cords with prongs on both ends||Should allow easy connection between 2 female connectors||data-sort-value="+5%"|~0%||data-sort-value="-80%"|-80%||Prongs on both ends would make it easier to plug the extension cord in on either side. But once plugged into an outlet, the other end becomes a serious shock hazard, as seen in [https://www.youtube.com/watch?v=L08LjkN1k70 this Backyard Scientist video]. Short circuits (both ends connected to outlets supplying power) would be much more likely, resulting in more sparks, fires and damage to wiring. Double-ended cords are also sometimes used as an especially dangerous way to feed power from a generator into an outlet, introducing a shock hazard to any utility workers attempting to restore power.

|Stair kayaking||Riding down a flight of stairs in a {{w|kayak}}||data-sort-value="-60%"|-60%||data-sort-value="-75%"|-75%|| Stair kayaking is a stunt where a person positions a kayak at the top of a flight of stairs and then, using their paddle to push off, [https://youtu.be/46BjHAxgddU?t=154 rides the kayak down the stairs]. This poses significant easily foreseeable risks of injury or death, as well as being very bad for the kayak, which is designed to ride on {{w|Kayak|water}}, not stairs.{{Citation needed}}
|-
|Fake prank fire extinguishers||A “fake prank” fire extinguisher would be something that appears to be a prank fire extinguisher, but is actually a real fire extinguisher. However, Randall appears to mean using a fake fire extinguisher as a prank. Intentionally placing empty or otherwise non-functional {{w|fire extinguisher|fire extinguishers}} as a {{w|practical joke}}.||data-sort-value="-105%"|-100%||data-sort-value="-85%"|-85%|| The idea of placing fake fire extinguishers as a prank, presumably so that a person who thinks they are grabbing a real fire extinguisher will instead find a decoy, sounds, and indeed would be, very dangerous and potentially life-threatening for many people. In the United States, (and presumably most countries), this would also be a felony in most, if not all, jurisdictions. This exact scenario was depicted in the 2001/Season 3 Christmas episode of Family Guy, where Brian failed to put out a fire because the fire extinguisher shot fake snakes instead, acting as further fuel to the fire. An example of a similar situation, although not intended as a prank, can be found [https://twitter.com/ThatSamWinkler/status/1657154071051239424 here].
The title text expands this idea by having the prank fire extinguishers filled with (leaded) gasoline. This is literally adding fuel to the fire.

|Always saying what you think||...regardless of the feelings of others or other considerations||data-sort-value="+65%"|65%||data-sort-value="-60%"|-60%||Openness and honesty are seen as positive character traits in people. Taking it to the extreme of ''always'' telling people what you think has been {{w|Radical_honesty|espoused by some}}, but can lead to awkward, unpleasant or dangerous situations. It may harm your relationship with the other person if they don't like what you think, or they may reply without concern for ''your'' feelings or other considerations. Keeping negative thoughts to yourself or telling "white lies" can be considered a better alternative in some situations.
Unrestrictively saying what you think to somebody in power (a boss, soldier, dictator, drunk) can negatively impact your earning potential, health or freedom, even if you have a point.

At worst, the spammer may extract sensitive information about you, make you a victim of a scam or gain control of your computer.
|-
|{{w|Solar car}}s||Having {{w|Solar panel|solar panels}} on the car's surface (mostly hood and roof) for power generation||data-sort-value="+95%"|95%||data-sort-value="-35%"|-35%||Powering electric vehicles with solar panels seems like an excellent idea: it would provide power with no increased land use, and theoretically could allow a vehicle to operate indefinitely without being fueled or charged. However, such vehicles would require power storage (due to power requirements, weather conditions, shade from roadside features and nighttime driving), adding significant weight. Adding solar panels to a plug-in or hybrid vehicle would add cost, weight, manufacturing complexity and maintenance requirements. Solar panels on moving cars are less efficient than in stationary installations, where they can be aimed at the Sun, and subject to damage from both collisions and road debris; even without these problems, the size of automobiles relative to their power requirements would sharply limit the car's range (unless it was a normal electric vehicle with supplemental solar panels). Solar cars do exist (the {{w|World Solar Challenge}} is a competition for such cars), but as a practical form of transportation, the negatives likely outweigh the positives. See also [[1924: Solar Panels]].

|{{w|Heelys|Heelies}}[sic]||Heelys are shoes with an inline skate wheel built in the sole, at the heel. ||data-sort-value="+25%"|25%||data-sort-value="-40%"|-40%||Heelys allow the wearer (usually children) to shift between normal walking and rolling like being on skates. This sounds like fun but [https://abcnews.go.com/Health/Exercise/story?id=3242181&page=1 has been suggested] to be a potentially significant injury risk.
|-
|{{w|Prequel|Prequels}}||A work of fiction (often a movie) telling the "story before the story" of another work.||data-sort-value="+75%"|75%||data-sort-value="-15%"|-15%||More of a good story sounds great on the surface, and audiences who are invested in a set of characters and/or a setting often love the idea of finding out what led up to certain events. But there are several pitfalls. Spin-offs of a popular property are often low-quality cash grabs. Prequels, specifically, are constrained by the fact that they have to lead to the story that's already been released, which can lead to contrived storytelling. There's less room for suspense, since the future of the storyline has already been established. There's a tendency to invent or fill in detailed backstories, which can undermine character arcs and/or destroy the mystery and nuance of certain characters. And, since they tend only to be made where the original is already well-received, regression to the mean tends to mean they are more likely than not to fail to live up to expectations. Prequels can be good, but there are a lot of ways they can go wrong.
|-
|Transitions® lenses||A brand name for {{w|Photochromic_lens|photochromic lenses}} in glasses or contacts, which get darker (like sunglasses) in bright light.||data-sort-value="+30%"|30%||data-sort-value="-20%"|-20%||Photochromic lenses are clear lenses that darken when exposed to UV light, then turn clear again when the UV is removed. The advantage is that wearers of glasses don't need to have separate (prescription) sunglasses or contacts. However, the process is relatively slow (about a minute) so not so useful when there is a quick succession of shade and bright light, as in a forest or when driving. If used in a car, the windscreen filters out UV light to some degree, which prevents the glasses from darkening as required. Finally, the process is temperature dependent, so in hot weather the glasses don't become as dark, and in cold weather they might stay dark for too long.

Additionally, the following should be considered. UV-conscious people protect their face against UV light, so the skin doesn't form wrinkles and ages slower. Sunscreen is difficult to apply around eyes without getting the substance on eyeballs (cosmetic substances should not get there{{Citation needed}}). One of the reasons behind wearing sunglasses may be to protect skin around eyes from forming so called crow's feet. Under UV-filtering sunglasses, UV-activated transitions contact lenses will not darken defeating their purpose. At the same time transitions contacts are typically at least twice as expensive as the regular ones.

2929: Good and Bad Ideas

}}

==Explanation==
This is a scatter plot comparing how good an idea sounds to how good the idea is. For example, leaded gasoline sounded like a good idea due to its anti-knocking effects, but is a bad idea due to lead toxicity. Fake prank fire extinguishers both sound bad and ''are'' bad, as they can make a dangerous situation worse. Putting mold on infections sounds like a bad idea, but some molds, like ones containing penicillin, have helpful antibiotic effects.

The title text combines leaded gasoline and a fake prank fire extinguisher into something worse than either. The fire extinguisher is fake and releases flammable material onto the fire, and there is additional lead toxicity.

===Table of the entries===
{| class="wikitable sortable"

|-
! Idea !! What it means !! How good it sounds !! How good it actually is !! Explanation
|-
|{{w|Leaded gasoline}}||Adding {{w|Tetraethyllead|tetraethyl lead}} as an antiknocking agent to allow for increased performance||data-sort-value="+65%"|65%||data-sort-value="-95%"|-95%||Leaded gasoline was introduced in the early 1920s to allow higher pressures and temperatures in an engine without causing {{w|Engine_knocking|detonation (knocking)}}, allowing for increased fuel efficiency and engine performance; it also works to prevent engine valve wear. In essence, it artificially raises the {{w|octane rating}} of the fuel, reducing the need for fuel refinement, thus reducing waste and/or expense. Lead, however, is both toxic and bioaccumulative, meaning that lead released into the air over decades built up to harmful levels in people (as well as other animals) and almost certainly contributed to a host of health issues. Some scientists even hypothesise that {{w|Lead–crime hypothesis|crime levels are influenced by lead exposure}}. (It should be noted that this only "[sounded] like a good idea" due to deliberate campaigns to obscure the known dangers).
|-
|{{w|Bloodletting}}||Releasing "bad blood" from the veins||data-sort-value="-90%"|-90%||data-sort-value="-100%"|-100%||You need (most of) your blood. Losing [https://www.ncbi.nlm.nih.gov/books/NBK542273/ more than 15%] of a person's total blood volume results in adverse effects. Bloodletting was performed as a medical procedure for at least 2000 years until the 19th century. The idea was to withdraw blood to balance the body's "humors". Despite this long history, the notion that bleeding someone is bad now seems like basic common sense, and it's now well-understood that blood-letting (outside of {{what if|98|certain rare and specific cases}}) does no good, causes significant harm and quite certainly causes many deaths.
|-
|{{w|Asbestos}}||Mineral which does not burn, tolerates extremely high temperatures and forms small fibers. These qualities make it excellent for insulation and fire protection||data-sort-value="+90%"|90%||data-sort-value="-80%"|-80%||Asbestos was used extensively in ships and buildings throughout most of the 20th century. Unfortunately, the microscopic fibers that make up asbestos greatly increase the risk of {{w|Asbestosis|lung disease}} and cancer when inhaled, causing its use to be banned in most countries.
|-
|Extension cords with prongs on both ends||allows easy connection between 2 female connectors||data-sort-value="+5%"|~0%||data-sort-value="-80%"|-80%||Prongs on both ends would make it easier to plug the extension cord in on either side. But once plugged into an outlet, the other end becomes a serious shock hazard, as seen in [https://www.youtube.com/watch?v=L08LjkN1k70 this Backyard Scientist video]. Short circuits (both ends connected to outlets supplying power) would be much more likely, resulting in more sparks, fires and damage to wiring. Double-ended cords are also sometimes used as an especially dangerous way to feed power from a generator into an outlet, introducing a shock hazard to any utility workers attempting to restore power.

|-
|Stair kayaking||Riding down a flight of stairs in a {{w|kayak}}||data-sort-value="-60%"|-60%||data-sort-value="-75%"|-75%|| Stair kayaking is a stunt where a person positions a kayak at the top of a flight of stairs and then, using their paddle to push off, [https://youtu.be/46BjHAxgddU?t=154 rides the kayak down the stairs]. This poses significant easily foreseeable risks of injury or death, as well as being very bad for the kayak, which is designed to ride on {{w|Kayak|water}}, not stairs.{{Citation needed}}
|-
|Fake prank fire extinguishers||A “fake prank” fire extinguisher would be something that appears to be a prank fire extinguisher, but is actually a real fire extinguisher. However, Randall appears to mean using a fake fire extinguisher as a prank. Intentionally placing empty or otherwise non-functional {{w|fire extinguisher|fire extinguishers}} as a {{w|practical joke}}.||data-sort-value="-105%"|-100%||data-sort-value="-85%"|-85%|| The idea of placing fake fire extinguishers as a prank, presumably so that a person who thinks they are grabbing a real fire extinguisher will instead find a decoy, sounds, and indeed would be, very dangerous and potentially life-threatening for many people. In the United States, (and presumably most countries), this would also be a felony in most, if not all, jurisdictions. This exact scenario was depicted in the 2001/Season 3 Christmas episode of Family Guy, where Brian failed to put out a fire because the fire extinguisher shot fake snakes instead, acting as further fuel to the fire. An example of a similar situation, although not intended as a prank, can be found [https://twitter.com/ThatSamWinkler/status/1657154071051239424 here].
The title text expands this idea by having the prank fire extinguishers filled with (leaded) gasoline. This is literally adding fuel to the fire.
|-
|Always saying what you think||...regardless of the feelings of others or other considerations||data-sort-value="+65%"|65%||data-sort-value="-60%"|-60%||Openness and honesty are seen as positive character traits in people. Taking it to the extreme of ''always'' telling people what you think has been {{w|Radical_honesty|espoused by some}}, but can lead to awkward, unpleasant or dangerous situations. It may harm your relationship with the other person if they don't like what you think, or they may reply without concern for ''your'' feelings or other considerations. Keeping negative thoughts to yourself or telling "white lies" can be considered a better alternative in some situations.
Unrestrictively saying what you think to somebody in power (a boss, soldier, dictator, drunk) can negatively impact your earning potential, health or freedom, even if you have a point. Or else, on the offchance that your (first) thoughts are less correct, [https://quoteinvestigator.com/2010/05/17/remain-silent/ "Better to remain silent and be thought a fool than to speak and to remove all doubt."]

|Replying to spammers||Clicking on the "Reply" button from {{w|spam email}}s and writing (and sending) a reply (or worse, clicking on the links in these emails)||data-sort-value="-50%"|-50%||data-sort-value="-50%"|-50%||At best, you confirm your email address and identify yourself as someone likely to respond to such messages and so encourage the spammers to deluge you with more messages. At worst, the spammer may extract sensitive information about you, make you a victim of a scam or gain control of your computer.
|-
|{{w|Solar car}}s||Having {{w|Solar panel|solar panels}} on the car's surface (mostly hood and roof) for power generation||data-sort-value="+95%"|95%||data-sort-value="-35%"|-35%||Powering electric vehicles with solar panels seems like an excellent idea: it would provide power with no increased land use, and theoretically could allow a vehicle to operate indefinitely without being fueled or charged. However, such vehicles would require power storage (due to power requirements, weather conditions, shade from roadside features and nighttime driving), adding significant weight. Adding solar panels to a plug-in or hybrid vehicle would add cost, weight, manufacturing complexity and maintenance requirements. Solar panels on moving cars are less efficient than in stationary installations, where they can be aimed at the Sun, and subject to damage from both collisions and road debris; even without these problems, the size of automobiles relative to their power requirements would sharply limit the car's range (unless it was a normal electric vehicle with supplemental solar panels). Solar cars do exist (the {{w|World Solar Challenge}} is a competition for such cars), but as a practical form of transportation, the negatives likely outweigh the positives. See also [[1924: Solar Panels]].
|-
|{{w|Heelys|Heelies}}[sic]||Heelys are shoes with an inline skate wheel built in the sole, at the heel. ||data-sort-value="+25%"|25%||data-sort-value="-40%"|-40%||Heelys allow the wearer (usually children) to shift between normal walking and rolling like being on skates. This sounds like fun but [https://abcnews.go.com/Health/Exercise/story?id=3242181&page=1 has been suggested] to be a potentially significant injury risk.
|-
|{{w|Prequel|Prequels}}||A work of fiction (often a movie) telling the "story before the story" of another work.||data-sort-value="+75%"|75%||data-sort-value="-15%"|-15%||More of a good story sounds great on the surface, and audiences who are invested in a set of characters and/or a setting often love the idea of finding out what led up to certain events. But there are several pitfalls. Spin-offs of a popular property are often low-quality cash grabs. Prequels, specifically, are constrained by the fact that they have to lead to the story that's already been released, which can lead to contrived storytelling. There's less room for suspense, since the future of the storyline has already been established. There's a tendency to invent or fill in detailed backstories, which can undermine character arcs and/or destroy the mystery and nuance of certain characters. And, since they tend only to be made where the original is already well-received, regression to the mean tends to mean they are more likely than not to fail to live up to expectations. Prequels can be good, but there are a lot of ways they can go wrong.
|-
|Transitions® lenses||A brand name for {{w|Photochromic_lens|photochromic lenses}} in glasses or contacts, which get darker (like sunglasses) in bright light.||data-sort-value="+30%"|30%||data-sort-value="-20%"|-20%||Photochromic lenses are clear lenses that darken when exposed to UV light, then turn clear again when the UV is removed. The advantage is that wearers of glasses don't need to have separate (prescription) sunglasses or contacts. However, the process is relatively slow (about a minute) so not so useful when there is a quick succession of shade and bright light, as in a forest or when driving. If used in a car, the windscreen filters out UV light to some degree, which prevents the glasses from darkening as required. Finally, the process is temperature dependent, so in hot weather the glasses don't become as dark, and in cold weather they might stay dark for too long.

Additionally, the following should be considered. UV-conscious people protect their face against UV light, so the skin doesn't form wrinkles and ages slower. Sunscreen is difficult to apply around eyes without getting the substance on eyeballs (cosmetic substances should not get there{{Citation needed}}). One of the reasons behind wearing sunglasses may be to protect skin around eyes from forming so called crow's feet. Under UV-filtering sunglasses, UV-activated transitions contact lenses will not darken defeating their purpose. At the same time transitions contacts are typically at least twice as expensive as the regular ones.

|Cutting pizza in squares||Cutting (a presumably round) pizza in squares||data-sort-value="-25%"|-25%||data-sort-value="-20%"|-20%||Most people cut pizza into wedges and hold it by the crust. Cutting it into squares could allow for more pieces to be shared, if the resulting wedges would be too thin to be practical. However, pieces near the center will have no crust to hold it by, getting cheese and sauce all over your fingers. Cuts around the edge will probably leave smaller leftover scraps which are mostly crust. While hardly a disaster like the other items in its quadrant, square pizza pieces are just not very useful and rather inefficient. Cutting a rectangular pizza into squares might not suffer from the problems above, but, unless the pizza itself is square and cut only into four squares, some people will end up with a higher crust-to-topping ratio than others. Cutting a round pizza into squares is popular in Chicago and is sometimes called tavern-style or party-cut and some<nowiki>[</nowiki>''{{w|Wikipedia:Manual_of_Style/Words_to_watch#Unsupported_attributions|who?}}''<nowiki>]</nowiki> [https://www.bonappetit.com/story/real-chicago-pizza-tavern-style consider it the real Chicago style pizza] [https://destinationeatdrink.com/the-real-chicago-style-pizza-isnt-deep-dish/ rather than deep dish pizza].{{Dubious}} St. Louis Style Pizza is also cut into squares.
|-
|{{w|Project Orion (nuclear propulsion)|Project Orion}}||Study by the U.S. government looking into nuclear pulse propulsion for spacecraft.||data-sort-value="-95%"|-95%||data-sort-value="-25%"|-25%||Using repeated nuclear explosions to generate motion sounds bad for both the spacecraft and everything else, especially with a ground launch, but there are ways to address a lot of the concerns, so it isn't as bad as it sounds. Project Orion's theorized specific impulse and thrust would also be far higher than anything chemical rockets can accomplish. The efficiency of Project Orion is extremely low, however, and the {{w|ablation}} issues are extremely difficult to overcome.

|Toasting sandwiches||Making a sandwich first and then cooking it, as in a dedicated {{w|Pie_iron|sandwich toaster}}, a {{w|toaster oven|toaster oven}}, frying pan or under a grill.||data-sort-value="+45%"|45%||data-sort-value="+50%"|50%||The grilled cheese sandwich is a familiar form to most people, and many other sandwiches are improved by toasting as a final step. Doing so makes the sandwich warm, while also making the bread crisp and crunchy, while often melting or softening the fillings, which provides contrasting textures that many find pleasing. Other sandwiches, such as the {{w|western sandwich|Western}} or {{w|club sandwich|club}} are prepared using toast. The {{w|peanut butter, banana and bacon sandwich|Elvis}} is a specific case of a sandwich that normally wouldn't be toasted, but is improved by it - peanut butter, bacon, banana and jelly, with the assembly lightly fried.

|{{w|Crumple zone}}s||Areas of a car that are designed to deform in a controlled way in case of a crash. ||data-sort-value="-55%"|-55%||data-sort-value="+55%"|55%||Most people's intuition would be that stronger cars are safer, and intending parts of a vehicle to collapse ''by design'' might seem crazy. But engineered crumple zones are designed to gradually absorb the kinetic energy in a vehicle collision and protect the passenger cabin. The result is that the occupants experience less intense deceleration and ideally without the damage significantly compressing the shell around them. This significantly reduces the danger of injury or death from higher speed crashes.

2903: Earth/Venus Venn Diagram

2026-03-27T06:44:48Z

47.141.37.161: /* Explanation */ We know what shockwaves are

{{comic
| number = 2903
| date = March 6, 2024
| title = Earth/Venus Venn Diagram
| image = earth_venus_venn_diagram_2x.png
| imagesize = 416x309px
| noexpand = true
| titletext = Actually, the fact that Mars is still orbiting safely over here means that it was technically an *Euler* apocalypse, not a Venn one.
}}

==Explanation==
A {{w|Venn diagram}} illustrates the relationships and differences among sets by showing common and distinct elements, using overlapping circles (or other shapes). This comic is both a '''Venn diagram''' and a '''proximity illustration''' of {{w|Earth}} and {{w|Venus}} colliding, physically 'overlapping' each other.
* As a '''proximity illustration''', it depicts Earth and Venus smashing into each other, resulting in "shockwaves and production of impact ejecta" occurring where they collide. The relative circle sizes are accurate; the circumference of Venus is 5% smaller than Earth's.
* As a '''Venn diagram''', it shows a collision moment in which the commonality between Earth and Venus is "shockwaves and production of impact ejecta" at the spot of intermingled Earth-Venus overlap.

'''Impact ejecta''' are the materials expelled from the impact site, consisting of molten rock, vaporized material, and solid debris, flung out at high velocities due to the energy released by the collision. The production of impact ejecta would indeed occur in the overlapping impact area.

The title text is [[2721: Euler Diagrams|another xkcd joke]] about the difference between a [[:Category:Venn diagrams|Venn]] diagram and an [[:Category:Euler diagrams|Euler]] diagram, which is similar to a Venn diagram except that it's acceptable to have circles (or other shapes) that do not intersect if there are no common elements between those sets. The observation that {{w|Mars}} is still orbiting by itself makes Mars an additional set (out of the frame of the diagram), in addition to - but not intersecting with - Earth and Venus, making this [[technically]] an {{w|Euler diagram}}. Therefore if the Earth-Venus collision is a "Venn apocalypse," the inclusion of Mars as a non-intersecting entity makes this technically an "Euler apocalypse."

Interesting comparison with the archetypal "labyrinth".

Not that there's a completely unambiguous term for the room with the toilet/lavatory/whatever in it.

:The logarithmic scaling should be compatible with [[wikipedia:Hyperbolic_geometry|hyperbolic geometry]]. However, the distance metric changes continuously in such a geometry.

::If we're committed to discontinuities (at least in undifferentiatable senses), we can just treat the floorplans as separately just traditional Euclidean but the main doors between 'levels' as a wormhole/portal. Moreover, one which could satisfy the rescaling requirement, (the 'door frame' outward is at the same metric of width/height as the inward one; ''as well as'' the inward one of one layer out, which is not experienced as a funnel). In a connected-voxel manner (as one might render it in virtual terms), every level of square-property has the exact same internal consistency.
::Save for the windows, which are additional portals limited only to the primary property (present on three walls, all but the 'inward exit' direction), secondary/tertiary ones (two walls, having both lost the 'entry wall' externality that faces their predecessor property) and quaternary (one windowed wall, now enclosed by the prime-property). All these windows similarly portal to the zeroth-level exterior (irregularly spaced, but 'proper-sized'), and of course whilst the 'obscured walls' (including all from quinary-level and beyond) could be not denied windows by being portaled to some surrogate external wall (infinite, necessarily!), in this example they are not.
::This renders the plans shown as 'wrong' (door widths are scaled differently at both inward and outward locations, with a single square sub-property, and such windows as exist from sub-levels (all nine window-outers on the external south-wall should be the same size as the nine inner windows from the primary square's outward-walls, not just the two and the door which are the direct identical ones).
::Thus rescaling issues as one traverses doors (or windows) go away. It does leave dissimilar distances inside and out (speed-of-light communications out of a Level 4 window and into a Level 1 one could be faster than any 'direct' through-wall one, if allowed, and of course diffracted propogation only via door-portals would be slower), but we're already talking of [https://wiki.lspace.org/Empirical_Crescent wormholing between/across domains], so our only real issue is how/if ''arbitrary'' knocking-through of holes through walls can be allowed (once the building is somehow BS Johnsoned into existence, perhaps at some point necessitating at least a countable infinity of builders/decorators).

}}

==Explanation==
{{incomplete|This page was created by boiling down a gorilla glue gorilla. Don't remove this notice too soon.}}

This comic refers to {{w|epoxy}} — substances used as adhesives, sealants, and coatings, named for the chemical substructure {{w|epoxide}}, which is the precursor component to these substances turning from liquids to solids.

[[File:FiveMinEpoxy.jpg|thumb|A typical 2-part epoxy applicator.]]Many types of epoxy are multi-part (usually two-part), where the components, such as {{w|resin}} and a {{w|Epoxy#Curing|hardener}}, are stored separately. For ease of use, this can be in parallel syringes (of equal volume, or proportionately different widths to maintain the correct mixing ratio) such that the user simultaneously squeezes out the separate chemicals onto the initial surface or into a container, by depressing both syringes simultaneously. The user then thoroughly mixes the components, as quickly as possible. The mixture is spread evenly (or as necessary) over the surface(s) to be joined or protected, and if there are multiple parts they are quickly positioned. The combined epoxy quickly cures, usually within a few minutes. This comic presents a fictitious 16-part epoxy, with the same apparent logic of parallel deposition in mind, with many components that are implausible or make fun of common problems people have when using epoxy in real life.

The title text references how not all epoxies and glues work on every material, and that applying them on some can require special techniques or products. Some industrial or industrial-grade adhesives contain solvents (e.g. {{w|tetrachloroethylene}}, which is used in E6000 glue) that release harmful vapors as they cure. If used improperly, this can result in the release of chemical vapors in an enclosed space along other dangerous side-effects, while also not working as a glue as intended.

{| class="wikitable"
|-
!Type
!Real?
!Explanation
|-
|Resin
|{{Yes}}
|A liquid which turns into a polymer when mixed with a hardener.
|-
|Hardener
|{{Yes}}
|A thick liquid which is mixed with resin to create a durable polymer which is commonly used as a glue.
|-
|Filler
|{{Yes}}
|An optional addition to the hardener and resin which changes the properties of the polymer.

Some epoxies are sold as products known as 'fillers', used to repair and cover cracks, holes, and imperfections.
|-
|Softener
|{{Yes}}
|The word is probably being used in humorous contrast to the "hardener" component, and perhaps also by analogy with laundry products that contain a fabric softener alongside a detergent. However, {{w|plasticizer|plasticizers}} are often added to polymers to make them more pliable, and thus to increase their impact resistance. These plasticizers tend to be lost over long periods of time (e.g. by evaporation or degradation), which contributes to old plastic becoming brittle.
|-
|Rosin
|{{Yes}}
|While this looks like a joke entry, this is actually a different kind of resin which is extracted naturally rather than synthesized from other chemicals. Rosin (a kind of '{{w|Flux (metallurgy)|flux}}') is one of two parts that make up rosin-core solder, used in electronic work, where the rosin is located in the center (the "core") of the wire-like solder, similar to how graphite is in the core of a pencil. When heated hot enough to melt, it {{w|Soldering#Flux|cleans corrosion and oxides from the surfaces}} of the metal parts to be joined, creating bare metal surfaces that can be 'wet' by the solder. In rosin-core solder, the two substances are touching rather than kept completely separate, since they're both in solid form, and don't react with each other even when they're heated to melt them. In this respect they differ from common combination epoxy chemicals that will be both liquids that cure together on contact even at room temperature. Rosin is also frequently applied to the bows of string instruments like violins or cellos to improve the sound, as immortalized in the famous song "{{w|The Devil Went Down to Georgia}}" or the folk song {{w|Old Rosin the Beau}}.
|-
|Stuff that bonds permanently to skin and nothing else
|{{No}}
|One key annoyance with sticky substances is the difficulty of removing them when they are inadvertently applied to skin. In this case, the polymer bonds solely to skin instead of anything else, making it mostly only really useful for a practical joke. Some epoxies are specifically designed for gluing skin, usually for medical purposes, but none are known to bond to skin exclusively.{{acn}} This may be a reference to {{w|cyanoacrylate|cyanoacrylate adhesives}} ("super glues"), which famously bond quite aggressively to skin while often failing to bond the target materials.
|-
|Stuff that will crack and turn white over a few days, for decorative appearance
|{{Maybe|Not effective as epoxy}}
|'Crackle effect' is a real thing for crafters, and can be created by mixing paint and glue, but is not recommended if you want two surfaces to adhere, since most paint is made to be non-adherent in order to be durable{{acn}}. Poor finish, where an intended smooth uniform surface cracks or discolors, can be a frustrating problem when applying epoxy mixtures to visible surfaces, especially when the problem only appears some time after you've congratulated yourself on a job well done.
|-
|Placebo
|{{Maybe|Not in the field of adhesives}}
|The {{w|placebo effect}} happens when somebody is told that something has a certain effect, when in reality it has no mechanism of action to produce that effect. This is commonly used in medical studies to determine whether a medication actually does something, as opposed to simply having a {{w|psychosomatic effect}}. Using this term to describe a type of polymer suggests it would make someone believe it is gluing things together without actually doing anything, which is unlikely. Alternatively, this could refer to a component or filler that claims to serve a specific purpose while having no true benefit, causing the perception of benefit to the consumer (presumably causing better reviews).
|-
|Minced duct tape
|{{Maybe|Not intentionally}}
|{{w|Duct tape}} is widely used as a way to join and/or cover things, sometimes in contexts where an epoxy might provide a more high-quality solution. [[Randall]] is pretending that having very small pieces of tape in the mix would add to the epoxy's ability to hold things together. In reality, cutting duct tape into small pieces would weaken it and make it ''less'' effective at sticking things together. In the UK, the word 'minced' can also mean 'made worthless', which would also not bode well for the adhesive.
|-
|Acetone fragrance
|{{No}}
|{{w|Acetone}} is a volatile solvent used in a number of glues and paints (including nail polish), but it weakens epoxy and can even be used to remove uncured epoxy. It has a strong, distinctive smell, and is actually toxic, making fragrance an odd reason for adding it to any product. It ''would'' give the epoxy a familiar "chemical smell" that people associate with industrial compounds. The use of 'X fragrance' in an ingredient list, instead of simply listing the ingredient X, usually implies that the actual ingredient is some (cheaper) substitute for X with a similar scent. Since acetone is already inexpensive, perhaps some substitute has been discovered that provides the smell without weakening this glue, though other joke entries value humour over adhesion.
|-
|Powdered bar magnets
|{{Maybe|Yes, but not in resin}}
|This might still work if the pieces could somehow be aligned correctly, as each tiny piece of magnet would still be a magnet in its own right, capable of attracting the other tiny magnets, and thus resisting tension forces. However, it would be much worse than a normal bar magnet, since the magnetic force would be weaker than those that held the original bar together. The micro-magnets would tend to clump together, which might strengthen the glue, but wouldn't help it to bond to surfaces very much unless the surfaces themselves were strongly magnetic.
|-
|Polyethylvinylesteracetate
|{{Maybe|Not in epoxy}}
|This appears to be a reference to {{w|ethylene-vinyl acetate|Poly (ethylene-vinyl acetate)}}, some formulations of which can be used as the adhesive in hot-glue guns. Vinyl acetate is an ester, so the inclusion of that term is redundant. The cadence of the constructed word may also be a reference to the television episode {{w|Lucy Does a TV Commercial}} and its memorable product "Vitameatavegamin". It also resembles the kind of thing often seen in ingredients lists for common household products such as soaps and cleaners, which are fairly meaningless to the average person buying them.
|-
|2-Polyethylvinylesteracetate
|{{Maybe|Unclear}}
|This sounds almost exactly the same as the above item, but {{w|2-Polyprenyl-6-hydroxyphenol methylase|a name with a "2-" prefix}} generally indicates that the initial bit of the name is a {{w|functional group}} attached to the ''second'' position along a chemical chain (often being the carbon-carbon 'spine' of a molecule, in large-molecule organic chemistry), rather than attached to its end. Because the molecule name is (possibly deliberately) malformed, it's hard to tell what is supposed to be attached to the second carbon of what subunit.
|-
|Salt and pepper to taste
|{{Maybe|Not for taste, but salt can be useful}}
|Salt and pepper are two incredibly popular condiments which are used to enhance a dish's flavor, and "salt and pepper to taste" is a phrase found in many food recipes. But the taste of your epoxy should not be your concern. Do not eat epoxy.{{citation needed}} However, salt, sand or other fine grains are sometimes recommended to add a bit of grit to an adhesive. Generally glues or epoxies need the bonded materials to be firmly held together while the glue cures. But when first pressed together, any excess glue is squeezed out and can cause the surfaces to slip around and need to be re-aligned. Any extra friction in the epoxy can help alleviate that.
|-
|Blood sample from the Gorilla Glue gorillas
|{{No}}{{Citation Needed}}
|{{w|Gorilla Glue}} is a popular brand of superglue which uses {{w|gorillas}} as its mascot. In this case, the blood of the gorillas would be extracted and placed in the polymer, which would dilute and possibly weaken it. Insofar as Gorilla Glue gorillas exist, they are depicted as ordinary gorillas who just happen to carry glue everywhere, so the effect would be the same as with blood from any other gorilla. Extracting and consuming the blood of a creature or person in an attempt to inherit some of the qualities of the 'donor' is a kind of {{w|sympathetic magic}}, so this may be suggesting that including this will give the epoxy 'the strength of a gorilla', commonly considered a powerful animal.

Blood has been [https://www.sciencedirect.com/topics/engineering/blood-glue historically used in glue], though not typically that of gorillas.
|-
|Stuff that bonds to every known material except yours
|{{No|Probably not}}
|Another common annoyance when using an adhesive is that each glue type only forms an adhesive bond with certain materials. In this case, the polymer would bond with every material except for the one you were using, causing great distress and leaving you in a fix. This is similar to "Stuff that bonds permanently to skin and nothing else" above.

This comic refers to {{w|Epoxy}} — substances used as adhesives, sealants, and coatings, named for a particular {{w|Epoxide|chemical substructure}} that's key to these substances turning from liquids to solids. Many types of epoxy are multi-part, usually two, where the components, such as resin and a hardener, are stored separately. For ease of use, this can be in parallel syringes (of equal volume, or proportionately different widths to maintain the correct mixing ratio) such that the user simultaneously squeezes out the separate chemicals by depressing both syringes at once, onto the initial surface or into a container. The user then thoroughly mixes the components, as quickly as possible. The mixture is spread evenly (or as necessary) over the surface(s) to be joined or protected, and if there are multiple parts they are quickly positioned. The combined epoxy quickly cures, usually within a few minutes. This comic presents a fictitious 16-part epoxy, with the same apparent logic of parallel deposition in mind, with many components that are implausible or make fun of common problems people have when using epoxy in real life.

The title text references how not all epoxies and glues work on every material, and that applying them on some can require special techniques or products. Some industrial or industrial-grade adhesives contain solvents (e.g. {{w|tetrachloroethylene}}, which is used in E6000 glue) that release harmful vapors as they cure. If used improperly, this can result in the release of chemical vapors in an enclosed space along other dangerous side-effects, while also not working as a glue as intended.

|Resin
|{{Yes}}
|A liquid which turns into a polymer when mixed with a hardener.
|-
|Hardener
|{{Yes}}
|A thick liquid which is mixed with resin to create a durable polymer which is commonly used as a glue.
|-
|Filler
|{{Yes}}
|An optional addition to the hardener and resin which changes the properties of the polymer.

Some epoxies are sold as products known as 'fillers', used to repair and cover cracks, holes, and imperfections.

|Softener
|{{Yes}}
|A substance which is added to polymer to soften the polymer and increase its impact resistance.
|-
|Rosin
|{{Yes}}
|While this looks like a joke entry, this is actually a different kind of resin which is extracted naturally rather than synthesized from other chemicals. Rosin (a kind of '{{w|Flux (metallurgy)|flux}}') is one of two parts that make up rosin-core solder, used in electronic work, where the rosin is located in the center (the "core") of the solder. When heated hot enough to melt, it {{w|Soldering#Flux|cleans corrosion and oxides from the surfaces}} of the metal parts to be joined, creating bare metal surfaces that can be 'wet' by the solder. In rosin-core solder, the two substances are touching rather than kept completely separate, since they're both in solid form, and don't react with each other even when they're heated to melt them. In this respect they differ from common combination epoxy chemicals that will be both liquids that cure together on contact even at room temperature. Rosin is also frequently applied to the bows of string instruments like violins or cellos to improve the sound, as immortalized in the famous song "The Devil Went Down to Georgia".
|-
|Stuff that bonds permanently to skin and nothing else
|{{No}}
|One key annoyance with sticky substances is the difficulty of removing them when they bond to skin. In this case, the polymer bonds solely to skin instead of anything else, making it mostly only really useful for a practical joke. Some epoxies are specifically designed for gluing skin, usually for medical purposes, but none are known to bond to skin exclusively.{{acn}} This may be a reference to {{w|cyanoacrylate|cyanoacrylate adhesives}} ("super glues"), which famously bond quite aggressively to skin while often failing to bond the target materials.
|-
|Stuff that will crack and turn white over a few days, for decorative appearance
|{{Maybe|Not effective as epoxy}}
|'Crackle effect' is a real thing for crafters, and can be created by mixing paint and glue, but is not recommended if you want two surfaces to adhere, since most paint is made to be non-adherent in order to be durable{{acn}}. Poor finish, where an intended smooth uniform surface cracks or discolors, can be a frustrating problem when applying epoxy mixtures to visible surfaces, especially when the problem only appears some time after you've congratulated yourself on a job well done.
|-
|Placebo
|{{Maybe|Not in the field of adhesives}}
|The {{w|placebo effect}} happens when somebody is told that something has a certain effect, when in reality there is no effect. This is commonly used in medical studies to determine whether a medication actually does something as opposed to simply having a {{w|psychosomatic effect}}. Using this term to describe a type of polymer suggests it would make someone believe it is gluing things together without actually doing anything, which is unlikely. Alternatively, this could refer to a component or filler that claims to serve a specific purpose while having no true benefit, causing the perception of benefit to the consumer (presumably causing better reviews).
|-
|Minced duct tape
|{{Maybe|Not intentionally}}
|{{w|Duct tape}} is widely used as a way to join and/cover things, sometimes in contexts where an epoxy might provide a more high-quality solution. [[Randall]] is pretending that having very small pieces of tape in the mix would add to the epoxy's ability to hold things together. In reality, cutting duct tape into small pieces would weaken it and make it ''less'' effective at sticking things together. In the UK, the word 'minced' can also mean 'made worthless', which would also not fare well for the adhesive.
|-
|Acetone fragrance
|{{No}}
|Acetone is a volatile solvent used in a number of glues and paints (incl. nail polish), but it weakens epoxy and can even be used to remove uncured epoxy. It has a strong, distinctive, very unpleasant smell, and is actually toxic, meaning that fragrance is an odd reason for adding it to any product. It ''would'' give the epoxy a familiar "chemical smell" that people associate with industrial compounds.
|-
|Powdered bar magnets
|{{Maybe|Yes, but not in resin}}
|This might still work if the pieces could somehow be aligned correctly, as each tiny piece of magnet would still be a magnet in its own right, capable of attracting the other tiny magnets, and thus resisting tension forces. However, it would be much worse than a normal bar magnet, since the magnetic force would be weaker than those that held the original bar together. The micro-magnets would tend to clump together, which might strengthen the glue, but wouldn't help it to bond to surfaces very much unless the surfaces themselves were strongly magnetic.
|-
|Polyethylvinylesteracetate
|{{Maybe|Not in epoxy}}
|This appears to be a reference to {{w|ethylene-vinyl acetate|Poly (ethylene-vinyl acetate)}}, some formulations of which can be used as the adhesive in hot-glue guns. Vinyl acetate is an ester, so the inclusion of that term is redundant. The cadence of the constructed word may also be a reference to the television episode {{w|Lucy Does a TV Commercial}} and its memorable product "Vitameatavegamin". It also resembles the kind of thing often seen in ingredients lists for common household products such as soaps and cleaners, which are fairly meaningless to the average person buying them.
|-
|2-Polyethylvinylesteracetate
|{{Maybe|Unclear}}
|This sounds almost exactly the same as the above item, but {{w|2-Polyprenyl-6-hydroxyphenol methylase|a name with a "2-" prefix}} generally indicates that the initial bit of the name is a {{w|functional group}} attached to the ''second'' position along a chemical chain (often being the carbon-carbon 'spine' of a molecule, in large-molecule organic chemistry), rather than attached to its end. Because the molecule name is (possibly deliberately) malformed, it's hard to tell what is supposed to be attached to the second carbon of what subunit.
|-
|Salt and pepper to taste
|{{Maybe|Not for taste, but salt can be useful}}
|Salt and pepper are two incredibly popular condiments which are used to enhance a dish's flavor, and "salt and pepper to taste" is a phrase found in many food recipes. But the taste of your epoxy should not be your concern. Do not eat epoxy.{{citation needed}} However, salt or sand or other fine grains are sometimes recommended to add a bit of grit to an adhesive. Generally glues or epoxies need the bonded materials to be firmly held together while the glue cures. But when first pressed together, any excess glue is squeezed out and can cause the surfaces to slip around and need to be re-aligned. Any extra friction in the epoxy can help alleviate that.
|-
|Blood sample from the Gorilla Glue gorillas
|{{No}}{{Citation Needed}}
|{{w|Gorilla Glue}} is a popular brand of superglue which uses {{w|gorillas}} as its mascot. In this case, the blood of the gorillas would be extracted and placed in the polymer, which would dilute and possibly weaken it. Insofar as Gorilla Glue gorillas exist, they are depicted as ordinary gorillas who just happen to carry glue everywhere. Extracting and consuming the blood of a creature or person in an attempt to inherit some of the qualities of the 'donor' is a kind of {{w|sympathetic magic}}, so this may be suggesting that including this will give the epoxy 'the strength of a gorilla', commonly considered a powerful animal.

Blood has been [https://www.sciencedirect.com/topics/engineering/blood-glue historically used in glue], though not typically that of gorillas.
|-
|Stuff that bonds to every known material except yours
|{{No|Probably not}}
|Another common annoyance when using an adhesive is that each glue type only forms an adhesive bond with certain materials. In this case, the polymer would bond with every material except for the one you were using, causing great distress and leaving you in a fix. This is similar to "Stuff that bonds permanently to skin and nothing else" above.

"Duck" tape, not "duct". Come on Randall, you know better than that. [[User:Yorkshire Pudding|Yorkshire Pudding]] ([[User talk:Yorkshire Pudding|talk]]) 00:08, 15 January 2026 (UTC)
:Both spellings are used. One is trademarked. [[Special:Contributions/76.187.17.7|76.187.17.7]] 03:46, 15 January 2026 (UTC)
:Read this: https://archive.is/Fq5Js [[User:Viliml|Viliml]] ([[User talk:Viliml|talk]]) 09:36, 15 January 2026 (UTC)
::But "duct" ''screams'' folk etymology. "Duck" sounded unlikely so people though it must be "duct"...but it's a huge leap to think that a tape that some people tended to use for a/c ducts would actually be ''named'' "duct tape". Both the tape and the word "duct" are too general purpose for that. Is it known as that? Yes? Does it make sense though? Not for a second. [[User:Yorkshire Pudding|Yorkshire Pudding]] ([[User talk:Yorkshire Pudding|talk]]) 10:38, 15 January 2026 (UTC)
:::To be fair, it is more commonly used for taping ducts than it is used for taping ducks [[Special:Contributions/2A01:CB1C:12EF:7900:953B:FFB2:21E3:47EC|2A01:CB1C:12EF:7900:953B:FFB2:21E3:47EC]] 12:43, 15 January 2026 (UTC)
:::Actually, it was originally named duck tape, as it was made using something called "duck fabric." This had etymology unrelated to the animal duck, from a Dutch word "doek." There were some similar tapes seeing some use with that name beforehand, but it became common as during WWII, a kind of it was adopted by the military for sealing ammunition crates, and it's availability led to soldiers widely using it for other purposes. After the war, it was then sold to civilian markets. Common use on air ducts led to it being made in the same gray color, and being labeled "duct tape." Many had forgotten the original name when in the 70's someone decided to call it that again while advertising it with a cartoon duck picture.--[[Special:Contributions/2600:100A:B10C:6B2E:EC47:CF99:9B14:1C81|2600:100A:B10C:6B2E:EC47:CF99:9B14:1C81]] 08:00, 16 January 2026 (UTC)
:::To add on to that point, the most popular use for pipe cleaners (other than elementary school craft projects) is to clean pipes, so it's not ''that'' much of a stretch. --'''''[[User:DollarStoreBaal44|DollarStoreBa'al]][[User Talk:DollarStoreBaal44|Converse]]'''''

Now I'm wondering what the properties of a powdered bar magnet would even be, if each individual piece continued to be magnetic. [[Special:Contributions/2405:201:E010:1029:2C1E:1669:FA92:85DE|2405:201:E010:1029:2C1E:1669:FA92:85DE]] 00:44, 15 January 2026 (UTC)
:A magnetic powder stops being diamagnetic. All the north poles clamp onto a south pole, so the magnetic fields essentially all cancel. You end up with "lump of magnetic powder", not "one big magnet" or "powder you can disperse in a liquid." [[User:Nitpicking|Nitpicking]] ([[User talk:Nitpicking|talk]]) 03:32, 15 January 2026 (UTC)
:: But all the little pieces of magnets are still full magnets with a north and a south pole. Magnetic monopoles have, so far, not been observed in practice. --[[User:Coconut Galaxy|Coconut Galaxy]] ([[User talk:Coconut Galaxy|talk]]) 06:32, 15 January 2026 (UTC)

So, the 2-poly(etc) seems to me to suggest that instead of being "-vinyl-ethyl-vinyl-ethyly-" polimerisation, with the links between both 'ethyl-like' backbone subcomponents being from opposite ends of the respective subunit carbon-pairing, it'd more likely now be considered as a polymethyl-group with a methyl (or methylene) group as the now unused onward '1-'site, hanging free of the new polychain. I'd have to check the bond-geometries, though to see if it would even work. (Ignoring the obvious problem with the made up name.) [[Special:Contributions/92.23.2.208|92.23.2.208]] 01:44, 15 January 2026 (UTC)

I feel like the Polyethylvinylesteracetate is a joke about how polymer names are often long and gibberish-sounding. [[User:Potatocakethrow|Potatocakethrow]] ([[User talk:Potatocakethrow|talk]])

Rosin is also used soldering, which might be relevant to adhesives. Soldering is used to join pipes, among other things. [[User:Nitpicking|Nitpicking]] ([[User talk:Nitpicking|talk]]) 03:32, 15 January 2026 (UTC)

:>"Rosin is also used soldering, ...to join pipes" Plumbing (pipes) soldering more often uses "acid flux" (Zinc Chloride and similar), not rosin which is used in electronics and jewelry. --[[User:PRR|PRR]] ([[User talk:PRR|talk]]) 05:48, 15 January 2026 (UTC)

While it's less common in glues than other animal products (such as skin, bones, or cheese), blood-based glues are (or historically were) a thing. Citation: https://www.sciencedirect.com/topics/engineering/blood-glue
Gorillas would not be a suitable source of this blood, though. {{unsigned ip|178.251.89.99|07:09, 15 January 2026}}

The traditional song "Rosin the Bow" may be less well known than "The Devil Went Down to Georgia", but rosin is in the title. [[Special:Contributions/87.75.47.93|87.75.47.93]] 10:46, 15 January 2026 (UTC)

How would you even squeeze that thing

I'm here from exactly two years in your future. Well, perhaps not ''your'' future because... ah... best not say, just in case. [[Special:Contributions/92.23.2.208|92.23.2.208]] {{#time:H:i, j F Y|+2 years}} (UTC)

Why does the end of the explanation appear to have been written by AI? Am I going crazy or does that look like how ChatGPT would describe xkcd? [[User:CreatorOfWorlds|CreatorOfWorlds]] ([[User talk:CreatorOfWorlds|talk]]) 22:52, 31 December 2025 (UTC)

'''"Anyone else here?" vs. "Anyone else now?"'''. It's always fun overanalyzing why *this* point in space-time is a here or now, while *that* point in space-time is a there or then. [[Special:Contributions/84.233.216.138|84.233.216.138]] 00:31, 1 January 2026 (UTC)

I think the explanation discounting it as a "trick" is disingenuous. It would be like calling a forum user creating a new topic "engagement farming". [[Special:Contributions/64.114.211.52|64.114.211.52]] 06:41, 1 January 2026 (UTC)

It should be"The Hitchhikers Guide to the Galaxy".

On the contrary, almost all the fanfiction I write is set in Legends, so my productivity takes a major hit there. (I don't care what disney says, they can take the old republic from my cold dead hands) [[Special:Contributions/108.254.161.83|108.254.161.83]] 02:09, 20 November 2025 (UTC)

I think the capital letter is significant. A Canon wiki would be about the Japanese company that makes fine optical equipment, something that would be a legitimate business-related destination.[[User:Muttley|Muttley]] ([[User talk:Muttley|talk]]) 09:57, 20 November 2025 (UTC)

Someone has put in "like Google" as an example. Should this site be extending the internet myth that Google is essential for internet use? In reality, it's just one of many search engines. If Google went down, people would get a less skewed result from something like DuckDuckGo. But they think Google IS the internet. And this wiki shouldn't ecoueage the myth. {{unsigned ip|86.45.82.77|10:22, 20 November 2025 (UTC)}}

The 'doesn't rely on' curve is wrong - it should initially plummet as the person repeatedly refreshes the Star Wars Legends wiki, while cursing it for (still) not working. [[Special:Contributions/82.13.184.33|82.13.184.33]] 10:46, 20 November 2025 (UTC)
:I thought the same for people who rely on it. There should be a big spike down, while people keep refreshing and debugging things, then it gradually goes up again, often to almost the same level as before, as people focus on tasks that they can do without that service or find workarounds.

I feel [[903:_Extended_Mind]] might be relevant as well? {{unsigned ip|173.70.43.163|17:07, 20 November 2025}}

Is there some separate Star Wars canon-only wiki that I'm not aware of that this comic is referring to? The main wiki to my knowledge is Wookieepedia which has both Legends and Canon information (generally a subject in both just has two separate pages and a link at the top to switch between Legends and Canon), but if that server goes down it's going to bring down all the articles on canon and legends equally so the distinction the comic makes seems meaningless to me. Maybe I'm just being pedantic. --[[User:Espella|Espella]] ([[User talk:Espella|talk]]) 00:44, 21 November 2025 (UTC)
