Double Card Prediction
4m 42s
IN ADDITION to a double-backed card you require an envelope, a slip of paper and a pencil. Beforehand take any two cards, say AC and 2S and write their names on the slip of paper. Put this in the envelope and fasten the flap down. Place any indifferent card face up between the face-down AC and 2S and put the three cards on the top of the pack, the indifferent card being the second card and face up. Finally place the double-backed card on the top of the pack. Begin the feat by handing the envelope to a spectator to hold. Riffle shuffle the cards, keeping the four top cards in position and covering the pack well with your hands in the action to avoid exposure of the faced card. Take off the top card, turn the pack face up, and hand the double-backed card, just removed, to a spectator, inviting him to thrust it into the pack anywhere, face down. Thrust the pack forward and have him do this quickly so that he will have no chance of turning the card over. Have him cut the pack, then turn it face down and spread it on the table. One reversed card is visible and is naturally taken to be the card just inserted by the spectator. Let him draw out the card above and the card below the faced card, leaving them face down. Invite him to open the envelope and read your prediction. The two cards are turned and prove to be the very ones named.
