This one happens so FAST!
Show an empty crystal glass. Cover it for an instant- and the glass is suddenly full of liquid! The liquid can then be freely poured from the glass.
Of course, you can also use this great prop to make a silk appear or disappear, change a silk to liquid, etc. And it's THAT easy- if you can hold the goblet in your hand, you can do the trick!
Quality manufactured from a real crystal glass goblet. Sealed compartment keeps the liquid contained, and the intricate crystal cuts make this a very deceptive mirror glass.
The Mirror Glass is a similar effect, but made of plastic.
