Sigh . . . Ki is not a toy. It took me a decade to learn the very basics of it. Anyone who attempts to teach or learn it over the internet is only playing with a basic excercise. You will never fly, shoot a ki blast or do anything of that nature. If, for arguments sake, it's possible, you would need decades and decades of training in it to use it. No one who learns it off the web has the discipline or the experience neccesary.
That, and every time someone post something like this, people who know nothing about you laugh at you and mock you. (You are all lucky I am feeling generous, and are getting off light for flaming.) If you are serious about it, find a master, learn from him, gain his trust. Otherwise, give up now.
