This trick very easy, yet it amuses even clever people. It can be used for all kinds of prediction tricks involving cards, depending on the magician's innovation.

The Effect:

   The magician writes down a card on a piece of paper. The paper is then folded and handed over to a spectator. The magician then takes a pack of cards and shows that it is only a normal pack. He then shuffles the pack and asks the spectator to make a cut. The cut pack of cards is turned over the rest of the cards.
