Real magic happens in the spectators hand, and Echec & Mat does just that. The effect is totally self-contained and leaves your hands completely empty. A brass disk, held in the magician's hand, changes magically from black to white to black, again and again. It isn't long before the spectator realizes that the disk is white on one side and black on the other. I mean, it doesn't take a rocket scientist to figure that one out, right? The magician now places the chip in the hand of the spectator. When he opens his hand, he finds he's been checkmated. The chip is now black and white checkers on both sides! The impact is so strong and the effect is so clean that when the spectator realizes what has happened, he can examine the disk to his heart's content and not discover the secret. Manufactured in brass by European craftsmen. You receive Echec & Mat, packaged in a foam lined jewelry box with complete instructions.
