The performer displays an empty cylinder, a clear glass & another glass full of liquid.
The liquid is poured into the cylinder, and magically stays suspended in the cylinder.
A handkerchief or silk is now past through the cylinder to prove it empty.
Finally the clear glass is passed through the cylinder and emerges full of liquid, which can be drunk or past to a spectator.
The cylinder is again shown completely empty.

Supplied complete with powder coated metal cylinder, glass, gimmick & instructions.
