Anyone ever come across anybody claiming to do this? I've seen one vid online which was kind of wierd(somewhere on here: http://www.whitetigerkungfu.com/). What do y'all think of that sort of thing? I'm a skeptic myself, but I really don't have any kind of chemistry background to know how that could be faked... nor do I know the science and theories behind qi/qigong to know if such a thing should be possible :P If you can't find the vid, he basically rubs his fingers together and a smoke/vapor apears from his hand. To show that his hand doesn't have anything on it, he washes it with some Agax, and a toothbrush(odd way to wash your hands ).
