Mental Die

The mentalist lets a spectator examine a small cylinder closed on one side, its lid and a die, all of them being made of brass. This may also happen with the magician’s back turned on the audience.
The spectator chooses a number from the die and puts the die back in the cylinder with his chosen number face up. Afterwards he closes the cylinder with its lid.
The performer turns back towards the audience, grabs the cylinder and after concentrating for a few seconds, names the chosen number.
In the end the spectator opens the cylinder showing the correct insight.
