The Changing Ace
Effect: You hold the Ace of Clubs, Diamonds, and Spades, spread out like a fan so that everyone can see them. You turn them face down, have someone tap them three times (the "magic" number,) turn them face up, and the Ace of Diamonds has now amazingly changed to the Ace of Hearts!
Card Trick: You say you are holding the Ace of Diamonds, but you are really holding the Ace of Hearts. When you fan out the cards make sure that the Ace of Hearts is upside down so the point of the heart is up. Put it in the middle, but on the bottom, with the other two overlapping it enough so only a red diamond shape shows in its center. It will seem to be the Ace of Diamonds. Turn the cards face down and have someone tap them three times. Lay the cards down, separately, one at a time, and it appears that the Ace has changed!
