Best made ESP matching board on the market- and you can show BOTH sides!
The effect is simple: you have five ESP symbol cards, and your spectator has five cards that match yours. You put each of your five cards into the slots on the board so that only you can see which order they are in. Your spectator then hands you each of his cards, and FREELY CHOOSES which order he wants them in. He can change his mind, change the order as many times as he wants. When he is finished, you turn the board around to reveal that all the cards match!
This is a really amazing effect that will leave them stunned every time! It's your choice to perform it as a lighthearted magic routine, or as a serious "experiment" in psychic ability. Either way, it's a reputation maker!
