The magician shows a cube to the audience, each side of which is a different color. “I just learned a new game. The winner is the one who throws a red! The champion is the one who can throw a double red!”
He throws the cube, and two cubes roll apart on the table! The magician takes hold of one of the cubes and slaps it on the table in front of a member of the audience saying “Why don't you try it? Here is a cube, have a throw!”
When he raises his hand from the cube, it is seen to have become completely flat.
There is no way that anyone can throw it now!
Everything can be immediately examined by the audience!
