In the title text, Randall claims to have been banned from the county fair for handing out helium-2 balloons because of the instant massive explosions caused by its radioactive decay. He jokes they violated a local ordinance. Helium balloons are often given out at county fairs and similar events, but they are filled with helium-4 and therefore inert. A balloon filled with helium-2 is a practical impossibility because of its sub-nanosecond half-life. Assuming a 12-inch diameter balloon at 1 atmosphere of pressure, the balloon-bomb would have a yield of roughly 18 {{w|TNT equivalent|tons of TNT equivalent}}.

This comic is another one of Randall's Tips, this time to reduce costs or provide something for free for physicists to save money on their research. None of these would provide any real advantages even when possible to implement. It continues the previous 2648: Chemicals comic's jocular theme of tricks to supposedly save money based on misinterpretations of science. Obtaining money from physics experiments was also described in 2007: Brookhaven RHIC.

Cost-Saving Tip Explanation
Try replacing regular vectors with pseudovectors whenever possible
Relationship of pseudovectors torque (τ) and angular momentum (L) to "regular" Euclidian vectors position (r), force (F), and linear momentum (p) in an oscillatory rotating system. Not shown is the centripetal force of the spoke's tension, a Euclidian vector towards the axle proportional to linear momentum, converting it to angular momentum.

The prefix "pseudo-" refers to an inauthentic variation of something. Fakes are usually cheaper than their original brand-name product, while often working just as well, so the comic implies a pseudovector could be a less expensive substitute for a regular vector. On the contrary, pseudovectors, or axial vectors, are distinct from regular Euclidean vectors, the former usually being involved with rotation or physical effects that share properties with rotation, similar to the relationship between angles and lengths. Pseudovectors are formed from the cross products of Euclidean vectors, in three dimensions, and while similar to Euclidean vectors, there is no physical meaning to their specific direction, only their magnitude and portions of their position. For example, angular momentum is described by a pseudovector, labeled L in the comic, normal to the plane of rotation, originating from the center of rotation, with magnitude equal to the angular velocity of rotation ω multiplied by the moment of inertia I. (The comic's diagram is drawn according to very uncommon left-handed coordinates instead of the standard right-hand rule. Randall is right-handed.[1])

A square wave can be broken down into an infinite supply of valuable sine waves Fourier analysis can decompose any periodic function into a series of sine waves. A square wave can thereby be represented as the sum of an infinite series of sine waves. However, the sine waves are not removed or separated individually, so such a Fourier transform does not produce a "supply" of sine waves for practical use in any tasks other than analysis, and as abstract mathematical objects exempt from the laws of supply and demand, their value is similarly limited.
Cut waste by buying lighter isotopes that don't have any dead-weight neutrons Chemical elements are identified by the number of protons in each atomic nucleus, equal to the number of electrons in their shell (unless the atom is ionized), which dictates most of their chemical behavior. Isotopes are variants of the element with different numbers of neutrons in the nucleus, among which chemical behavior is usually nearly identical. The comic suggests that the neutrons don't serve any useful purpose, so, in theory, if purchasing an element by weight, and its isotopes have the same price per unit weight, then you can save money by buying isotopes with no neutrons at all. In reality, the cost per unit weight for material containing a larger concentration of normally rare isotopes, such as heavy water or enriched uranium, is much higher than the cost of material containing isotopes in their ordinary proportions. (An exception is depleted uranium, which costs less than regular uranium because it is a byproduct of the production of enriched uranium.) In addition, a certain range of neutron quantity is needed to keep atoms stable, as atoms with too many or too few neutrons will decay more quickly than the common isotopes. The image shown is helium-2, an isotope of helium which has a half-life of less than a nanosecond. It decays into two ionized hydrogen atoms, releasing a large amount of energy—hence the explosions mentioned in the title text.
Conductors are a great source of free electrons (may carry charges) Free electrons are electrons that are not tightly bound to specific atoms so they can move freely, such as in conduction bands of the metallic bonds throughout the iron ingot depicted in the comic. Randall interprets "free" in a different sense, meaning no cost. The charges free electrons carry are electric, not monetary as implied by the pun.

In the title text, Randall claims to have been banned from the county fair for handing out helium-2 balloons because of the instant massive explosions caused by its radioactive decay. He jokes they violated a local ordinance. Helium balloons are often given out at county fairs and similar events, but they are filled with helium-4 and therefore inert. A balloon filled with helium-2 is a practical impossibility because of its nanosecond half-life. Assuming a 12-inch diameter balloon at 1 atmosphere of pressure, the balloon-bomb would have a yield of roughly 17 tons of TNT equivalent.

Calculations

Helium-2 has a half-life of roughly 10-9 seconds, or one nanosecond, and a mean life of roughly 1.44 nanoseconds. For context, light travels at roughly 30 cm per nanosecond. This means that on a human scale the energy is released all at once, and we only have to calculate total energy released, and not worry about time taken.

Helium-2 decays through 99.99% proton emission. For simplicity's sake, we'll call that 100%. Helium-2 is formed from two hydrogen-1s, and 1.25 megaelectron-volts, or as an equation,

1
1
H +
1
1
H + 1.25 MeV =
2
2
He. It therefore follows that decay from a helium-2 atom to two hydrogen-1 atoms would release 1.25 MeV,[citation needed] per the conservation laws of energy and mass.

A moderately-sized balloon might have a diameter of 12 inches. Some calculations give this a volume of roughly 14.83 liters (assuming a spherical balloon.) If the balloon is at 1 atmosphere of pressure at 25 degrees Celsius, then there would be 0.6058 mol in the balloon, mean that there is 0.6058 * 6.022×1023 atoms, or 364,800,000,000,000,000,000,000 atoms.

To recap, a helium-2 atom decaying results in 1.25 MeV of energy, and there are roughly 365 sextillion atoms in a balloon.

Every atom will create 1.25 MeV of energy, and therefore 365 sextillion atoms will create 365*1.25 sextillion, or 456 sextillion MeV. Interestingly, this is equal to 456 nonillion electron volts, or 4.56 megayottaelectron-volts. 456 sextillion megaelectron-volts is also equal to roughly 73,100 megajoules, or 17.4 tons of TNT equivalent.

The smallest nuclear bomb, the W54, had a yield of between 10 and 1,000 tons of TNT. The largest conventional bomb, the GBU-43/B MOAB, has a yield of roughly 11 tons. The 2020 Beirut explosion was roughly equivalent to 300-1200 tons. So, while the helium-2 balloon bomb would be larger than all conventional bombs, it would still be smaller than most nukes. Handing out what are effectively small atomic bombs at a county fair would not go down well with any surviving local authorities, so merely being banned is a very mild punishment. Criminal charges such as mass murder and terrorism would be more likely if it weren't for the absurd impossibility of the scenario.

Discussion

I don't recommend trying to make your voice squeeky by breathing He-2. Barmar (talk) 19:57, 22 July 2022 (UTC)

But breathing a helium-rich mixture in general... so long as it still has sufficient oxygen in it ...I would speak highly of it! 162.158.34.221 20:27, 22 July 2022 (UTC)

Please link comic 2007. I tried to do so myself but the edit errored.172.70.86.34 22:17, 22 July 2022 (UTC)

The vandals are going rather hard today. Can we get the first few semi-protected or something please? SqueakSquawk4 (talk) 22:24, 22 July 2022 (UTC)

I think I've fixed it. At least, it was fixed when I left this comment. I also don't do much wiki editing on anything, so I hope I actually fixed it and didn't break anything in the process. EDIT: Not sure if editing comments is appropriate, but it's just before 7AM UTC and it seems the vandalism has stopped. I think I had to fix it twice after I originally left this comment NErDysprosium (talk) 06:37, 23 July 2022 (UTC)
They're back. Semi-protecting may work (though at a cost in useful edits); if any of the major contributors to this site know tricks to track down the physical location of an editing IP, that might open up other approaches. 172.70.230.3 03:33, 24 July 2022 (UTC)
They're going after templates and similar infrastructure pages. Banning the little klanshit's username would be a good first action. 172.69.71.30 03:40, 24 July 2022 (UTC)

Are the "charges" that free electrons carry implied to be monetary or criminal? 162.158.2.219 22:27, 22 July 2022 (UTC)

Fundamental particles have dipole-matic immunity. 172.70.211.88 01:47, 23 July 2022 (UTC)

Somone needs to rewrite that section on heavy water / enriched uranium... deuterium in heavy water has more neutrons (so fits the comics description), and u235 is actually neither the lower nor upper neutron count for natural uranium so also questionably fits the description. I would but my head hurts after trying to parse it 108.162.221.79 11:20, 23 July 2022 (UTC)

Is it worth mentioning the L and omega displayed in the first illustration are in conflicting directions (not following the right hand rule…)?172.70.210.145

How sinister! 172.70.91.80 19:28, 23 July 2022 (UTC)
Done, including a video proving Randall is right-handed, so that can't be the reason. 172.70.206.163 07:45, 24 July 2022 (UTC)

I disagree with the calculation of the energy of the ²He filled balloon: ²He -> H + H + 1.25MeV (Wikipedia). One Balloon is approx. 30-40l, i.e. approx 2 moles = 2 Avogadro Number = 1.2e24 Atoms of ²He. This means 1.2e24*1.25MeV = 1.9E24MeV = 3e11J = 71 ton of TNT (@4.2e9J/ ton of TNT (Wikipedia)). That is much less than a kiloton of TNT, but probably above the limit for recreational fireworks. The balloon might pop, too.

Agreed; corrected. 172.70.211.88 09:15, 24 July 2022 (UTC)
I have done my own calculations, and come to a number of roughly 18 tons of TNT. I have put my calculations on my profile, and linked it. Please comment there if you disagree. Thanks! SqueakSquawk4 (talk) 13:37, 24 July 2022 (UTC)

The statement "This would make the Helium-2 balloon-bomb the most powerful human-made non-nuclear explosion ever" would seem to be inaccurate, given that it is not actually a non-nuclear explosion. Should this be edited? 172.70.110.135 03:43, 24 July 2022 (UTC)

Deleted the sentence. 172.70.211.88 04:43, 24 July 2022 (UTC)

How much yield would a Helium-2 baloon have, anyway? I've seen "Lots", "2 kilotonnes" and "70 tonnes". Does anyone know how to calculate it once and for all, and leave a citation trail?

I just had a small search around, and can't seem to find the decay energy of helium-2. Does anyone even know how to calculate this???} SqueakSquawk4 (talk) 11:24, 24 July 2022 (UTC)

Scroll up a couple threads. 172.69.34.32 11:02, 24 July 2022 (UTC)
I didn't see that. I'm doing my own calculations now anyway. SqueakSquawk4 (talk) 11:24, 24 July 2022 (UTC)

Great! I replied to you there. 172.70.207.8 14:40, 24 July 2022 (UTC)

Fantastic what-if on electrons. I love the idea that making the moon out of electrons would create a naked singularity with the mass of the universe. 172.70.211.134 07:47, 26 July 2022 (UTC)

Dear Simulation Operator(s), please do not try that. 172.70.211.134 08:45, 28 July 2022 (UTC)

Could the title text potentially be a play on "ordinance" and "ordnance" (the latter of which refers to explosions)? 172.69.34.18 21:58, 31 August 2022 (UTC)
