A small wooden block (1”x2” x3”) is placed on your table. Concentrating on the block the magician can cause it to move, slide or fall at will…or. Cover the block with a glass or jar or pitcher and without touching it you can “psychic energy?” get it to fall over.. There are no moving parts, wires or threads. As a “yes”or “no” indicator the block can move side to answer questions. Completely under your control at all times.
