Russian Roulette
In this video, Derren Brown of TV's "Mind Control with Derren Brown" plays a game of Russian roulette. He brings in a young gentleman and has him choose in which chamber a live round is placed. A shield is then placed over the chamber so that Derren does not know in which chamber the bullet is. He then determines one turn at a time which of the numbered chambers has a live round in it by either aiming at the target across the room or his head.
