The magician fills an empty transparent glass with water, beer or any other beverage and then drinks it. He then places the glass on a tray (or a book, a wooden plate or a glass plate) and places a silk over it. He now asks the audience if the glass is heavy or light. He asks a spectator to lift the glass a little bit, which is no problem. The glass seems to be light, as the spectator (it could even be a child) can easily lift it up. The glass is then placed onto the tray again.

Now the magician looks into the spectators eyes while saying The glass is heavy. Its really heavy. Its so heavy that you cannot even pick it up. The spectator tries to lift the glass but with no success! Its simply too heavy for him to pick up! It seems to be heavier than lead, heavier than gold, heavier than any known material!

The magician breathes against the glass and it becomes light again, so that even a two year old child can pick it up! Its nothing more than an ordinary drinking glass. But...
... if the magician wants it so, even the strongest man cant lift it up. Just a simple breath and the glass is as light as a feather again.

No, you are wrong: there are no gimmicks used. No hooks, no thread loops, no mechanism. The silk and tray are unprepared. No sleight of hand is required, the item is ready to go! No assistants or helpers from the audience are needed. Unexplainable, spooky and funny at the same time. Can be performed surrounded!

Comes with a special glass in a very attractive box and detailed instructions. Use your own silk and tray/plate.
