Twins

Duplicity of events – impressively presented with a spectator and only four cards. You show a small rack with your prediction in the form two giant cards. To start with, however, they are facing away from the audience to ensure that no-one is influenced in any way. You ask a spectator to shuffle a normal deck of cards, thoroughly and for as long as he or she wants. The spectator then takes two cards from the deck. This is done completely without any trickery, interference or manipulation. The two chosen cards are rested against the giant cards. The giant cards are then taken from the rack and turned over. The spectators see that your prediction is 100% right. The values of the giant cards and the cards chosen by the spectator are identical.
