Another winner from Nick Trost! The performer and the spectator each hold several unknown cards. The spectator takes his cards behind his back, draws out one and gives it to the performer, who reverses the card in his packet. Likewise, the performer gives the spectator one of his cards, which the spectator reverses in his packet. When the packets are brought forward and fanned, the two reversed cards are the same, say two 5C's. The spectators think all the other cards must be 5C's, but when shown, all are duplicates of an entirely different card-say the 3H's! Everything can be examined! Easy to do. Complete with all the cards.
