A very strange object – the innards of a Switch Pitch! Ball
The photographs show how these loosely jointed pieces of plastic are able to flex. In one configuration the orange discs are in the middle and the green discs on the outside. In the other configuration the discs have changed positions – the orange ones are now on the outside and the green ones are in the middle. The third photograph shows the half way stage. This unusual behaviour explains how a Switch Pitch! ball (for details see Ref. no. N1614) manages to change its colour when it is thrown up into the air. The effect is distinctly magical.
