Yep. I\'ve used the one foot levitation before. Very simple.
Notice how David Blane gets everyone to stand on one side and bunched together? Then he\'d stand at an angle so that they can\'t see the foot that\'s away from them. That\'s the foot he uses to tippy toe on. And - remember, he\'s usually in a shadow. That way they can\'t see the shadow of his foot holding him up.

Remember, there\'s only ONE camera man with him. The camera man is always facing the people to catch their reaction. Next, there\'s another footage from the PEOPLE\'S angle - where you see him levitate about 12 inches off the ground. Where\'d that camera man come from?
Simple.
The editing room!

Yes, boys and girls. He will use wires to levitate. Then splice in the footage with the rest of the taping.
TADAAAA!
He\'s a fake. A great conjurer of cheap tricks, yes.....but he\'s no Gandalf.
Oh...and he will use "spies" to slip cards into people\'s pockets and such.
