You put a small packet of three cards, which are held together by a paperclip, in full view on a table. They appear to be two jokers, between which you have put a prediction. Now you take a deck of cards as well, shuffle it a few times and give it to a spectator, who may start to deal the cards down one at a time, face down. He can stop whenever he wants, and put the rest of the deck away. The dealt cards will now be divided into four separate packets. Now he may chose any of those packets. A completely free choice! When the spectator now turns over the top card of each of the non-chosen packets, they appear to be three cards of the same value (for example: three of the four twos). After everyone has calmed a bit after this surprise, you take the prediction from between the jokers. It turns out to be the fourth two! Ultimately, the top card of the packet chosen by the spectator is turned over and… it is a duplicate of the fourth two!
