Slap the Deck Effect: The magician fans out cards, and asks a spectator ...
The Flying Aces
Effect: The performer gives an audience member all Red cards in a deck and the Ace of Spades. The performer turns around while the audience member places the Ace into the Red cards and shuffles any way that they would like. The performer then turns around takes the cards into his hand. He gives the cards a few shakes and the Ace magically flies into the air.
You must have an Ace of Spades from another deck with an alike back to perform this trick.
Before the trick you must remove all black cards accept the Ace of Spades from the deck. Also hide the other Ace of spades in your pants pocket or anywhere else where the audience cannot see it.
Give the red cards and Ace of spades to the audience member. Turn your back to act like your not watching the member shuffle. What you are actually doing is pulling the other ace from your pocket and Back palming it. Back palming is a method where you place the card face down on the back of your hand. Then grip the top-right corner between your pinky and ring finger, and grip the top-left corner between your index and middle finger. This will put the card flush against the back of your hand. Make sure no edges are showing on the palm of your hand.
When the member is done shuffling turn around (make sure to keep the back of your hand turned away from the audience to conceal your card). Tell the member to place the shuffled cards in your hand face up (the one with the card). Give the cards a couple of shakes then move your hand in a jerking movement while loosening up on the ace on the back of your hand. This will send the card flying in the air. When it lands the audience will be amazed and think that this was the original Ace.
