Effect:
Four cards are placed in a row, faces up. While performer's
back is turned a card is turned end for end. He finds the one that has
been reversed.
Preparation:
This is a development of the very old trick which was done
by using cards the white margins of which were a little wider on one
side than the other.
In this method pick out of a pack of Bicycle cards the K, Q and J of S. Note the small white spades used in the body of the design. The J has five small spades pointing up or down according to the way the card is turned. The Q has seven pointing to left or right and in the center of the K design the large jewel is shaded at one end only.
Procedure:
- Lay these cards in a raw face up noting the way the designs point and
invite a spectator to place any other Court card down with them.
- Turn your back while the spectator turns one card end for end. If he turns one of the S you recognize it by the changed position of the design, but if these are unchanged then you know that the fourth card must have been turned.
