This is a classic sucker effect that kids love to see. You show a glass of milk on a tray and vanish it by covering it with a cylinder. You then accidentally reveal the secret behind this magic to show that the glass was actually pushed into the hole on the tray. You then actually vanish the glass of milk without a trace. The table cloth on the tray can be ripped open to show that the glass has truly vanished and that it is not hidden anywhere. Due to the unique construction of the cylinder it can be used on its own as a ghost tube.
The tray measures around 13 1/2" by 5". The cylinder is over 6" in height.
