    Edit: accedentally used the wrong density. Should be the desity of the surounsing medium (air) at 1.23 kg/m3- density of helium making it slightly more fesable. I.e. i was wrong on almost an order of magnitude, but its still infeasable… thanks @exasperation, @noneofyourbuissness

    So… hear me out. Yes i know its just a comic… im just autistic. Soooo…

    Assuming the guy is average weight (70 kg) the total force of gravity on him is Fg=70×g N. The force of boyancy would be Fboyancy=dhelium×Vdisplacemwnt×g N.

    If thease are in equilibrium (the guy floats): Fboyancy=Fg

    dhelium×Vdisplacemwnt×g =70×g

    If dhelium is 0.178 kg/m3 then 70/0.178 = Vdisplacemwnt= 393.5 m3≈ 1.9 m3 per condom.

    Like i know condoms are super strechy (can hold about 40L air befor burating) but wow. Thats like a phone booth per condom.

    Did you need this info?.. no. Was i compelled to calculate this? … no … stay in school kids.

      Classic rookie mistake.

      Not every store has an unlimited supply of condoms, especially the extra large ones*.

      He brought 200 at her store, and emptied the shelves. He probably hit a dozen places and brought all they had on hand.

      *I shall modestly refrain from enumerating the many, many times I myself have needed to purchase a vast number of extra large condoms…
