Effect: You put a card in your pocket, and one in the spectator's hand. Then the cards change places.
Pick up two cards from the top of the deck and make them look as if they were one (double lift). Show it to the audience, say the name of the card (we'll assume that it's the Queen of Spades) and put it back on the deck. Take the card that is really on top and put it in your pocket. Do another double lift, show this card and name it, and put it back on the deck. Take off the top card (which is actually the one that you supposedly put in your pocket), lay it on the spectator's hand, and tell him (or her) to put his other hand over it like a sandwich. Palm the top card and say "I am going to take out the Queen of Spades." Put your hand in your pocket, take out the card you just palmed and show it as you say "Turn your card over." When they do it looks as if your card and their card changed places.
