One thing I haven't seen mentioned which jumped out to me about the first theory is how would they have inflated the bag with breathable air in the first place?

- mc32 5y agoI imagine you could have two bags, one big one, connected to a smaller one and squeeze air from the bigger into the smaller (many ways)... but sheepskin isn't going to hold a lot of pressure and would just bust (not sure but not as good as a soccer ball) and given it's "hotdog" shaped and not spherical, it's probably not more than 2 - 4 psi.
