Performer displays a square board with five holes. A silk is pushed through one of the corner holes. The board is passed behind the performer's back, and the silk is found to have jumped to an adjacent corner. This is repeated several times and the spectators suspect the board is being turned behind the performer's back. The performer passes the board behind his back one more time, and the silk has now jumped to the middle. Complete with special "mechanical" board and the Silk.
