Long off the market, the Rattleback is an amazing demonstration of magic and physics! The magician spins this small “boat-like” object clock-wise on a hard table surface, and it spins just like it is supposed to. However a moment later the magician spins the boat in the opposite direction. At first the boat spins like it is supposed to, but then slows it spin, stops, and then begins to spin the other direction!  Use this cute easy-to-do effect to apparently control an object with your mind! The Rattleback is gold in color, about four inches long by about ¾” wide. It easily fits in the pocket and can be used almost everywhere. There is no skill or sleight-of-hand required and can be performed by all ages. 0521MM8508
