From a beautiful tea kettle, magician pours various coloured drinks, 15 to 20 glasses. Where do all these pretty coloured drinks come from? To show this, magician removes the cover of the kettle and produces a large load of coloured silks. He produces so many they would overflow the kettle if returned to it. Now the coloured drinks are poured back into the kettle and shaken up. Clear water is poured from the kettle ( or milk or beer).
