sjspeck:Anyone ever seen MindFreak? It's on A&E. Criss Angel does similar tricks.
He did a similar trick where he threw the cards at a window and the marked card was stuck to the inside of the glass. Then later he walked up to a family at an outdoor cafe, asked a little girl to mark a card never getting within 3' of her. When the trick was done, her card was in her back pocket. And she was sitting down...Amazing...
