Magician calls someone from the audience to assist in a trick. The magician selects a prediction card from a set of cards and lays it aside. From a different set the magician holds cards up one at a time and asks a spectator to stop at any point. The audience can see that every card matches the prediction (except for the spectator who is seated behind the performer). Once the spectator calls "stop"he is handed the card and asked to name it out loud for the audience to hear. Spectator names a DIFFERENTcard then what the audience just observed. The card is shown to the audience and it is in fact different. Looking confused the prediciton card is revealed and it too is different then what the audience thought. Miraculously the two cards match. Very entertaining magic! There are two special packs in this set.
