Hammer & ball box

This is an old trick, but the following description is copyright 1967 by the Inzani-Henley Magic Company Limited, London. A wooden ball vanishes from the performer’s pocket and appears inside a wooden vase. Now the procedure is reversed, but the ball refuses to vanish from the vase, so after a couple of unsuccessful attempts, the performer hits the ball with a wooden hammer and the ball vanishes instantly only to reappear back in the performer’s pocket.
