A plastic vase is displayed and the lid is opened to show that it contains a blue ball. The ball is taken out and placed in your pocket. Say a magic word, and open the lid again. The ball has returned to the vase! Close the lid once more, and say the magic word. This time when the lid is removed the vase is empty again and the ball has returned to your pocket!
Vase measures 3.5 inches high by 1.75 inches wide.
