Discern their thoughts!
Hand the spectator a cube and a small box into which the cube fits snugly. On each of the cube's six sides is a different design. The spectator selects one design, and places the cube into the box, while the magician's back is turned. Handing the box over to the magician is all it takes - the magician instantly knows which of the six designs was selected. Easy to do!
No sleight of hand. All the props are examinable. Manufactured by FUN Incorporated in the USA.
