Magician shows a 4 different sized glasses. The largest glass is filled with milk. But the Magician feels that it's too much for him to drink. So he pours it onto the next lower sized glass. This too is much for him . So he then pours it onto the third glass which is smaller. But the Magician feels that this is more as well. Finally he pours the milk into the tiny last glass. He feels that this is sufficient for him and happily drinks it. But wait.. where did all that extra milk go? No one knows .. but it definitely is Magic!
