A Cube Is Cloned And Squashed In Surprise Demonstration

The magician shows a cube to the audience - each side a different colour.
The cube is covered with one hand - the other hand copies the first, resulting in TWO cubes.
The magician now takes one cube and slaps it down on the table.
The result? One squashed cube.
The squashed cube and the regular cube can now be examined by the audience.
