Magic Show Prop - Sucker Glass Vanish

Performer covers a glass on a tray 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! Performer repeats the magic, and the glass is really gone. Additional effects possible with props supplied like Passe Passe Glass. Complete with cylinders, glasses and tray.
