Zennerism offers you the cleanest and easiest method to perform this devastating mentalism effect. You and a spectator each begin with a standard set of five different ESP symbol cards - Circle, Cross, Wavy Lines, Square and Star. The spectator pockets one of her cards and then, one by one, attempts to match each card you lay face down on the table by placing one of her own symbol cards face up on top of it. When the cards are finally flipped over - the symbols of every pair match exactly, including your last card and the spectator's pocketed card. Routine only--you'll need ESP cards (available seperately) to perform this.
