Twin Peeks by Paul Gordon
Effect: Two decks are on the table. The spectator places one in his pocket while the other is taken by the performer and shuffled. The spectator is asked to “peek” at one card. (This is a free choice of all 52 cards, no force.) The performer then dramatically reveals the name of the card plus names a number from one to fifty-two. The spectator takes out the second deck from his pocket and counts down to that number. It’s the same as the freely chosen card!
There is no memory or sleight of hand involved at all. Ideal for all performing situations. Easy to Prepare (Use Your Own Decks)
