YOUR CHOICE (DAN FLESHMAN)
Two cards are shown from a red deck. The queen of diamonds which is placed face up onto the table and then the ace of spades which is placed face down onto the queen. A spectator names either card. You then wave your hand over the packet, turn the packed over and a blue card is seen which is now the ace. You then turn the packed over again and the queen is now the card with the blue back, the ace once again has the red back. You now show both cards and they are both the queen of diamonds.
