#3 - This one he didn't do to me, but I watched him do with someone else. Similar to the deck of card trick, he had two balls one with "1" and one with "2" on it. The person held one in each hand, with his hands faced down. Then the magician did some hand waving, and told him to look, and the "1" and "2" balls had switched hands. The magician then took one of the balls in his hand and kept one in the persons hand. The person held the ball again with his hand faced down, some magic hand waving and presto, the guy now had both balls in his hand.
Fuckin cool. I wish I could learn how to do illusions like that.
