Novelty plastic ball – the beetle stays on top when you roll the ball

Immediately inside the clear surface of the ball is a thin layer of clear liquid. This allows the internal ball, which has the printing on it, to float inside. However, this ball is weighted inside, so that no matter which way the outer clear ball is turned, the beetle image always stays on top. The effect is quite magical for anyone seeing it for the first time. The words printed on the inner ball are: ‘Harlequin Cabbage Beetle. Copyright 1992. Club Earth. Taiwan’.
