You cannot dive with an inflated goatskin, unless you carry extra weight, like stones.

You cannot dive with an inflated goatskin, unless you carry extra weight, like stones.
- 3pt14159 5y agoSwords and armour are heavy.
- wil421 5y agoThen you would just become buoyant and not even sink. Try to bring a basket ball to the bottom of a pool. Grab some bricks and a basket ball then see what happens.
- simonh 5y agoAs soon as you breathed in the air from the skin, you would lose the buoyancy form it and sink to the bottom.
- djrogers 5y agoUmm, what do you think happens to the air in that skin when you breathe it? It goes into your body, and continues to provide buoyancy.
- treis 5y agoPeople exhale too.
- simonh 5y agoSo the person doesn't inhale deeply and hold their breath beforehand, and submerges with empty lungs? That seems, well, not ideal.
- mcswell 5y agoNo, it goes into your lungs and provides buoyancy for as long as you hold that breath. Some of the oxygen gets taken into your bloodstream, where it no longer provides buoyancy, but that's compensated by an (approximately) equal amount of CO2 that you exhale. But unless you blow it back in the bag, it ceases to provide you any buoyancy because it goes back into the atmosphere. (And if you do blow it back into the bag, your next breath will contain rather a lot of CO2...and the next one after that, even more.)
- djrogers 5y agoNot that heavy. Air displaces about 62 lbs of water per cubic foot, so a goatskin the size of your torso would require more weight than a soldier could carry to offset it.
- tomtomistaken 5y agoI think you are right and the depicted soldiers are not diving but floating. Maybe they carried their weapon in the bag, they all seem unarmed. Also I was wondering why they would continuously have to blow air in the sack. Probably they weren’t airtight.
