Sucker Glass Vanish

The Performer's assistant displays a glass on a tray. He covers the glass with a tube, slides the tube on the tray and lifts it up, and the glass is gone. The audience is not much impressed, because when the tray is accidentally(?) turned around, the glass is exposed, stuck in a hole in the tray !

The Magician repeats the trick. The Audience again thinks that the glass is under the try. This time, the Magician removes the cloth under the tray to show that the glass has indeed vanished, much to their amazement.

This is a great Quality product.
