Comedy glass in paper cone by Bazar De Magia

The magician takes a piece of paper from a newspaper and makes a cone with it. Then put a glass inside it. He turns around, in order to take a bottle of wine (or water). At that moment, the clown that is assisting him, takes the glass out of the paper cone, without the magician noticing that, letting the spectators understand his naughtiness. The magician turns again to the cone, and pours the wine (or the water) inside the paper cone, thinking the glass is still in the cone.
At that moment, the clown shows the glass to the performer, and the magician realizes he has a problem. Nevertheless, he takes the glass from the clown and introduces it into the cone, as he argues with the clown complaining of his misconduct. Then the magician makes a magic gesture and opens the paper cone: the paper is dry, and the wine (or water) is inside the glass!

Easy to do, also includes a routine for the performer alone.
