Cube to Anything

Show a cube and a tray. Drop the cube on the tray: upon impact the cube visibly transforms into another object such as: a sponge ball, a crumpled up banknote, a crumpled sheet of paper with a message written on it, many small colored silks, etc.. but you can also simply make it disappear!
Another idea is to have it transform into the famous cube with the various faces solved. To you the choice!

• The tray measures 29.5 cm (11,6") per side, while the cube measures 6.1 cm (2,4"). The various items into which the cube can be transformed are not supplied.
