A disk is displayed with 7 different animals on it. A spectator is asked to think of any of the animals.
The performer turns the disk over, and taps the holes under the animals in a random order with the tip of a pencil. The spectator is asked to secretly spell the name of his selected animal with one letter for each tap, and call out STOP when the complete name has been spelt. (For example if the spectator thought of Zebra, he would mentally spell Z-E-B-R-A, with one letter for each tap, calling out STOP on the fifth tap.)
With the pencil point in the hole the spectator called STOP at, the disk is turned over, to show the performer stopped under the Zebra or the selected animal.
