Show a roll if nickels, a small die and a small brass cup. Nickels are stacked on the table and the die is placed on top of them with the six side up. Covering the stack and the die with the cup, the magician then proposes to change the number on the die without touching the cup with his hands or removing it from above the stack. Someone then steals the die while the magician is not looking. But the magician accomplishes the impossible--not only does the die reappear, but he changes to spot on top of it in the process. Precision made in brass. Diabolical concept.
