No Brainer trick John Zander
The performer displays a wallet, which contains two identical sets of five cards, Ace through Five. The performer looks through the first set of cards and removes a prediction and places it back into the wallet. The spectator is then asked to look through the second set of cards and mentally select one of them. The second set of cards is then placed into the wallet along with the performers prediction.
At this point, the spectator is told that they may change their mind and choose a new selection. When the spectator is satisfied with their choice, the performer begins to remove the cards from the wallet one at a time. The spectator is instructed to name their selection when it is removed from the wallet. After all five of the second set of cards are removed from the wallet there is only one card left, the performers prediction, which is a match to the spectators mental selection!
