Maxello Magic

An ESP effect you can't pass by! Spectator deals 10 ESP cards face up in the shape of a pyramid. Magician now openly deals from the bottom of the deck a face down card on top of each face up card. As the cards are dealt, the spectator uses an "image receptor" consisting of a triangular piece of clear plastic to indicate which cards he thinks match and which do not.

When the cards are turned over, the spectator has "accurately predicted" the outcome. Everything can be examined!
