Four cards are selected and presented face down. One card is placed face down on the table. Just to make sure there are only 3 cards remaining, the performer counts them. The cards are lined up in hand and turned over to show 3 different cards. The fourth card on the table is flipped over to form a pair. A flick of the wrist and a pair becomes a 4-of-a-kind right before the spectators' eyes!
