The performer shows a transparent glass filled with a drink. He drinks some, until the glass is almost empty. Then, he puts the glass behind his back, or under his jacket for a moment, and when he brings it back into view the glass will be full of liquid again! During the performance the effect can be repeated as many times as desired!

A very magical "running gag"!

• The glass, made of plastic, is 13 cm  high (5,11") and has an upper diameter of 7.7 cm  (3").
