The Magic Cube - Economy

The performer shows a cube and tosses it in the air showing the audience that all its faces are completely mixed up. He then puts it in an elegant box and closes it with a lid. When he takes the cube out of the box, all its faces are now in order (each one of a different color). Finally he puts the cube in the box again and, after a moment, shows it once more. This time all its faces are… yellow!
 
• It is made of wood. The yellow cube measures about 10.5 cm per side. The box a little more.
