You remove a deck of cards from its case and spread it face up between your hands to show that it's in random order. In fact, you tell the spectator that the cards are in a random order...except for one card. And that card is the one you will subconsciously force him to select. He may think it is a free selection, but he can't prevent you from imposing it upon him! You return the deck to the case and ask the spectator to name "his" selection. Demonstrating that there is no way you can touch the cards, (they're in the case), the spectator removes the cards from the case and he will spell down to the card he selected. When he gets to the last letter, he'll be looking at his card!
