Change The Ace

Effect: The Ace of Spades changes to the Ace of Hearts.

Secret: Place the Ace of Hearts and the Ace of Spades on top of the pack. Turn over the top card and show it is the Ace of Spades. Place it back on the pack face up. Push the two top cards a little to the right, so they overlap the edge of the pack by one centimetre. Throw the pack firmly down on the table. Air pressure causes the two top cards to turn over and the Ace of Hearts will now be face up.
