90% of criss angels effects he either made up himself OR not on the market.
Not sure where that statistic comes from. Most of what he performs on the street is not at all original and you can totally buy them. You just have to know where to look. The reason you can't find his name attached to these tricks is because they are not his. He borrows ALOT from the countless consultants for his show which include Max Maven, Lance Burton, Johnny Tomson, Banacheck among many others. Even his famed levitation is a merely a twist on the Icarus effect. It's the same thing only in reverse. The razor blade or needle effect is as old as the hills and can be found in just about any "geek magic" DVD or book. As far as pulling it out of your belly button try combining it with something like Harry Anderson's needle through arm if you want to get creative and gross you may throw in some blood.
