You explain you have a new computer program that allows you to win in Poker using no computer. Then you show a CD that has ten printed face cards on one side and back cards on the other.
You hand the spectator five paper clips and the CD explaining that he will pick out your hand clipping any five facedown cards and that the remaining cards will be his hand.
Then ask him to turn the CD face up showing the five clipped cards to be… the winning hand!
