You hand over a small black plastic box for examination. Then you take an aluminum cube (2.5 cm edge length) out of your pocket and have it examined closely as well.

A spectator is asked to place the die into the box with any number facing up and replace the lid while you stand outside the room or face away.

You now ask the spectator to place the sealed box on your palm. A brief moment of concentration is all it takes, and you hand the box back to the spectator, loudly stating the number that the die is facing up! - You seem to have x-ray vision!

The experiment can be repeated any number of times without the spectators being able to find a solution to your 'supernatural' abilities!

• The lid is not secretly lifted or incorrectly placed (It may even be sealed...)
• You can't see through the lid or box.
• There are no secret openings in the box or lid.
• No gimmicks to remove or add.
• The trick principle has not yet been used in other trick routines.
