Ever Filling Glass (Locking)

Description

Magician shows a transparent glass full of liquid, such as milk, coke, etc. He drinks from it until the glass is almost empty. Then Magician places the glass under cover of his coat, or behind his back for a moment. When he brings it back out it is seen to be full of liquid once again! This can be repeated as often as desired. A very strong effect!

This is a newer version of an older effect that features a locking device which allows the glass to be resting on a table full of liquid before performing the effect.
