Ask your audience to inspect four cubes, all of which have a special feature: The tops and bottoms are marked with a coloured dot while the sides of each cube are numbered 1, 2, 3 and 4.
Next you show the audience an oblong wooden box open at one side.
You then put the cubes into the box in a random order (e.g. 1-4-3-2). The box is then covered with a cloth.
When the cloth is removed the cubes have magically transformed into the correc order � 1, 2, 3, 4.
