The magician produces a bottle or kettle and asks the audience to name any sort of drink: water, beer, tea, or any other liquid. The magician tips the bottle and pours out a glass of that drink. He then asks for another example, and another, with the bottle producing the drinks on demand, seemingly forever. At the end of the performance the bottle is broken open to reveal various objects. Kettles generally reveal a number of colored handkerchiefs inside, which are said to give the kettle its magical powers.
