Eleven Card Trick
The Eleven Card Trick is a trick created and published by Edward Victor, in which the magician announces he wants to perform a trick with eleven cards, and asks an audience member to count them onto his hand. Picking up the cards and counting them again, the performer finds he has only ten. He takes another card from the assistant, but upon counting again, he still has only ten. This can be repeated, adding and subtracting cards, but the magician is unable to end up with eleven cards when he ought to have exactly that many.
