A great piece of audience participation, which is a real mind bender for the participant. A number of ordinary playing cards are shown that have been cut in half. The two piles of halves are collected together, and the participant mixes the packet. The packet is than split into two facedown piles, and the participant freely selects which card from each pile to take. Having paired off all of the face down half cards, each pair can be turned over to show that the two halves match.

This is completely self-working, and puzzles young and old alike.
