The BALL AND VASE trick is a classic of magic. If you take a good look at the vase it has a secret lid that will reveal a secret 'half shell ball'.
Begin the trick by showing the vase with the 'whole ball' inside of the vase. Remove the ball and place it in your pocket. Tell your audience it will magically return.
When you say the magic words you remove the secret top lid of the vase to reveal the secret 'half ball' gimmick. It will look as though the ball has magically returned.
