Watch as their card pulls a HOUDINI!
This one is really different!
You start out with a very unique deck of cards.
The cards, including the card box, have a hole drilled right through one corner.
The hole is big enough for the metal loop of a padlock to fit through it.
Go ahead and riffle through the deck, letting your spectator call "stop!"
Let your spectator take a look at the card he chose.
Put the cards back in the box, and let your spectator feed the padlock through the hole.
Let him lock the padlock.
Now there is NO WAY any card can come out of the deck- or can it??
You state the impossible- you say that the chosen card has escaped the lock, and is now in your pocket!
Let the spectator unlock the padlock, and sort through the cards.
His card is MISSING from the deck!
Of course, you reach into your pocket- and take out THE CHOSEN CARD!
