Did Criss Angel invent that self levitation he does? He is constantly going around saying "my levitation". Did he invent that?

Yes, he even sells it.

Yes I know I actually own it. I actually just went back and rewatched it and Criss credits someone by the name of Jacob Spinny creating the concept AND having a rough prototype. So what I getting, from Criss Angel's own mouth is that Criss just made a nicer gimmick. So I'm not sure we can credit Criss with this since it was someone else's concept. I don't know that I'm shocked though. In another one of his dvds he reveals that the quarter in soda can was also not his creation.

He never said Sinful(quarter through can was his). And from what I've been told Criss' levitation is close to the Icarus Levitatioin, but done backwards.
