Given how it's nearly impossible to breathe under water without the air itself being pressurized, I highly doubt option one. If you ever tried breathing out of a tube underwater as a kid, you'll know exactly what I mean.
- Gustomaximus 5y agoI've done this with a tube as a kid and get what your saying. But would a goat skin underwater be the same? The tube example is because of the pressure difference. Having a bladder underwater the air would easily come out to breath. IMO the harder thing would be getting the bladder to stay underwater, especially at the picture size, that would have a heap of buoyancy to offset.
- mcswell 5y agoThe air in the bladder will be at exactly the same pressure as the water around it. Therefore if the diver were underwater with the bladder (a thing which I doubt, for reasons others have mentioned here), the air in the bladder would be at about the same pressure as the diver's lungs (about 0.2 psi higher, if the diver somehow managed to keep the bladder below him, as in the picture).
