"Invisible Dice" (#127)

INVISIBLE DICE(#127)

TRICK: The spectator rolls a pair of invisible dice. After doing what seems like some random math the magician divines the numbers that they rolled.
The magician hands someone an invisible pair of dice. He asks that they roll the dice and inquires, “What number did you roll?” After their response, the magician insists “Roll them again.” Upon complying the magician asks, “What number did you get this time?” After responding with a different number the magician proclaims, “So they are not loaded!” Everyone chuckles.
The magician asks that they roll the dice one last time. He adds, “This time don´t tell me what you rolled. Instead choose one of the two numbers that you rolled and double it. Now add five to your new number. Multiply the result by five and add the number on the other dice to it. What is your new total?” Upon their response the magician astonishes everyone by revealing the number(s) that they rolled. The magician adds, “Do you know how I guessed your numbers? It was easy… you left the dice sitting on the table.”

SECRET: The real method uses a little math.Let´s say they rolled a 5 and a 2.If they choose the 5 and double it that makes 10.Adding 5 to 10 makes 15.Multiplying 15 by 5 equals 75.Adding the other number 2 to that total equals 77.The secret is to subtract 25 from this last total!77 minus 25 equals 52.The result 52 translates that they rolled a 5 and a 2.

This always works. It is amazing!

If you decide to try this on an elementary school student, someone who has been drinking, or someone who just doesn´t seem that bright, you might want to hand them a pencil and paper or a calculator to work out the calculation. :-)
