Magician holds a tray with a glitter cloth on three sides of the tray. He also has a glass of milk on the tray which he covers with a metal tube. He drags the tube with the glass a little bit. On lifting the tube, it is found tht the glass with the milk has vanished! While taking a bow, he accidentally exposes the glass which is hanging behind the cloth from a hole in the tray. He apologizes and trys the trick again. This time the audience thinks that the glass is again hanging from the hole, but the magician shows the tube empty and rips the drape around the tray off. To the surprise of everyone, the glass of milk has totally vanished!
Very easy to do.
