He's basically an illusionis, but his stunts are beyond David Blaine.. Let me describe one of his stunts.
He gets lit on fire, and walks around for 45 seconds, then when he falls down onto his stomach and the EMT's put the flames out. He's gone, but his clothes are still on the ground laying out perfectly flat, still smoking. Then, one of the EMT's putting out the flames pulls his hood back and it's...actually...him? And he did this in front of a criwd if people in the middle of a street in Vegas.
And as for levitation. He can do it too, and everyone thinks, it's just a trick with camera angles right? Well, unlike Blaine, this guy comes FEET off the ground! He went into a restaurant. And levitated from the ground, on to a chair. Tell me how you do that with camera angles O_O
He made a girl levitate. Yes, not himself, a complete stranger. :|
