Its not magic. Its all an illusion that takes careful planning. He does things when we are not paying attention. He grabs our attention while doing his trick. While we are concentrated on his "trick" He is doing something else that we are completely oblivious too. He is an illusionist.
Criss Angel, along with all other magicians, bases his magic on optical illusions that trick the audience's eyes. Stunt doubles, trap doors, self-unraveling ropes, and other props aid Criss Angel in his "magic."
He is a trained illulisionist, and some of the people who are supposed to be strangers on the street are actually part of his act. All magic is simply slight of hand, do not be distracted, always watch the hands and not the magician and you will be able to figure out some of the tricks.
Criss Angel performs classic slight of hand technique. Criss also uses various props to increase illusion of things moving through tables, his skin, and mouth. Criss controls body and mind. Everyone always asks how did he make several persons disappear right in front of them. I think it is anyone's guess how he continues to amaze and amuse us.
He makes you believe one thing when another thing is actually true. A lot of his tricks are not that hard to figure out. He also has the use of a video camera so he can film one thing and make it look like a continuous shot. When it is really different shots put together.
A lot of it on TV is strictly camera tricks. I have noticed episodes where I can tell that the camera stopped. Also the fans on camera are usuallt actors
