Two sets of five ESP cards are freely displayed, one set with red backs, the other with blue. The red set is given to the spectator who shuffles them, the magician mixing the blue set. One at a time the performer places his cards face down onto the table and each time the spectator then places one of his cards at random next to the performer's. When the pairs of cards are turned face up, all five sets are seen to have been put down in matching pairs!
This is a streamlined version of my card matching routine which has extra subtleties and a cleaner handling than earlier versions.
