Effect: You read someone's mind.
Secret: Whilst your back is turned (or you can be blindfolded) someone throws a die on the table. Ask him to remember the number thrown and then to make another throw. Tell him to double the first number he threw and to add five to the answer. He has now to multiply his answer by five and then add on the second number thrown. Ask him what total he has reached. Mentally subtract 25 from the answer he gives. You will end up with a two digit number – the first digit is the first number thrown and the second is the second number thrown. Now pretend to read the spectator's mind and tell him what numbers he threw.
