This comic makes a pun on the fact physics work very differently at the atomic level. In the comic, Cueball, Megan, and White Hat have apparently hired an accelerator physicist to design a water park, portrayed as Ponytail. Ponytail decided that, in the event an emergency stop is activated on a large waterslide, the riders would be diverted to a "beam dump", a large block of graphite which Ponytail believes would safely slow the momentum of the riders. Of course, this wouldn't work on the human scale,[citation needed] as graphite is extremely solid and not good for slowing momentum of large objects.
However, in the context of a particle accelerator, beam dumps are actually formed of large blocks of graphite in order to safely slow the particles without having them release large amounts of energy.
The title text adds to the joke, with the park designers apparently utilizing flypaper to 'minimize reflection or scattering of customers'. Of course, this would not work, as humans would be able to perceive and avoid the flypaper, unless they are fully boxed in.

[Ponytail is standing in front of a diagram on the wall, pointing at it with a pointer. The diagram has a picture of a waterslide and some untelligible text. The waterslide has two paths at the bottom; one returns to the base of the entrance tower, the other goes to a large black block. On the right stand Cueball, Megan, and White Hat facing her.]
Ponytail: If the emergency stop is activated, any riders on the waterslide will be diverted into the beam dump, a large graphite block which will safely absorb their momentum.

We regretted hiring an accelerator phsycist to design our water park.

Started with an explanation. Wikilinks would be very useful. Get this done quickly; this will be confusing, even for xkcd readers. --DollarStoreBa'alConverse 22:16, 14 November 2025 (UTC)
I don't see why a large block of graphite wouldn't absorb the momentum effectively. If it's not working effectively enough, it's simply not large enough. Easy. --2A10:D586:3E93:0:1DF3:4522:835D:33DD 23:19, 14 November 2025 (UTC)
- Well, for one thing, the collision is too elastic, and you'll get reflection. And graphite is brittle. 163.116.145.79 15:32, 17 November 2025 (UTC)
I feel like there might be an implied reference to the Schlitterbahn Kansas City incident with their Verrückt ride. Obviously not the main, geek-oriented point, but maybe worth calling out? Kind of dark, in any case. 2605:A601:AC81:5C00:89A3:3829:B7F:41E6 01:48, 15 November 2025 (UTC)
Why would quantum mechanics be mostly unable to describe what happens on the macroscopic scale if one were able to fully calculate the equations of state for each elemental particle (i. e., quarks, gluons, electrons) from the (mass- and, in some way, age-dependent) 200–900 ronnaparticles (or possibly up to 1–2 quettaparticles if we don't simplify baryons to 3 quarks and gluons)? 2001:4C4E:1C02:B400:A0AA:7176:EDF2:27AE 21:58, 15 November 2025 (UTC)

Which fun hater removed all the [citation needed]? I'm not mad, I just want to talk. -2603:7001:F040:10F8:CD0D:6500:323F:8258 07:34, 19 November 2025 (UTC)
- Was this one of those times when there were {{Citation needed}}s all over the place? Or even just two very close together (each being quite subjectively humorous, on top of that).
- You can overdo them. People do overdo them. Other people make the judgemennt that they're not needed, or even excessive. Nothing personal, just not necessary to keep them. 82.132.236.44 18:04, 19 November 2025 (UTC)
- I added one of them back (the one in the middle paragraph, relating to the fact that slamming into graphite blocks poses a significant health risk. --DollarStoreBa'alConverse 20:27, 19 November 2025 (UTC)
