You can’t breathe when you are too deep. The outside water pressure is too great for your diaphragm muscles to overcome. I remember a Bill Nye Science Guy video from middle school where he tried to use a garden hose as a snorkel. The further down you go, the less you can breathe.
Also, wouldn’t a big-ass bag of air be crazy difficult to keep under water? Try keeping a beach ball under water…
Forget the gloves, when did toilet paper get to 90 bucks!?
