Aldo Colombini has been killing magicians and lay people with this electrifying routine which fools, entertains and causes a frenzy.
Two packets of jumbo half-cards are mixed. Have a spectator freely select a card from one of the packets and leave it protruding. Now simultaneously turn over the top cards of both packets. Each card is different until you reach the selected card. It matches the card in the other pile. A perfect match. As a kicker ending, turn both packets face down and start turning the cards over again. This time, each and every card matches.
Mere words can't describe this true miracle. Ungaffed, examinable and very easy to do. Comes complete with necessary jumbo cards and photo-illustrated instructions.
