Very, very dangerous stuff this is! I knew a guy in Rochester, NY in 1971 that was a pretty good swimmer and he darn near died from this stuff....and had he not had great friends in the pool while doing this...he would have died....My take, this should ONLY be attempted with people who know first aid....watching you every step of the way. Other then that, you are really asking for the box!
I also knew an off shore free air - deep diver who was world class and he came up in the Med. off Italy in a world class event with blood in his mask...near dead....Very dangerous stuff only for the careful and well trained!
