The performer displays a solid cylinder of brass (not a hollow tube), and a steel ball which can all be thoroughly examined. The ball is placed on top of the solid chunk brass and, quite mysteriously, begins to sink visibly almost out of sight. Then it returns to rise until it reaches the top of the cylinder again. Finest quality brass, steel ball, and complete instructions.
