Re:Exploding from decompression (Score 1)

If I remember correctly from the diving class I took thirty years ago it's one atmosphere per 33 feet. Also it's safe to dive up to 33 feet for as long as you like and come up without decompressing. So I expect that there's something more at work here than just the change in pressure--like the change in the boiling temperature of water at various pressures.

Still, they remind you to be sure to breath out as you surface. Holding your breath is a sure way to wind up in the hospital or morgue.
