Dangers of Liquid Nitrogen by Efreet 2002-04-30 21:40:37
My physics proffesor once told me that as a graduate, he had an instructor who put some liquid nitrogen in his mouth. He'd avoid getting burned by keeping it rolling around, but I certainly wouldn't try it. Dry ice, on the other hand, is much safer. If you get it right you can blow a pretty good smoke ring with the vapor from one of those when its in your mouth.
