Effect: While you are out of the room a three-figure number is chosen. On your return, you read your assistant's mind and reveal the number.
Secret: When you return to the room after a number has been chosen, you place your hands on either side of your assistant's head. Your friend now tightens and loosens his jaw for the appropriate number of times to signal each number in turn, pausing between numbers.As your fingers are near his temples you can feel this muscular movement so it is easy for him to transmit numbers to you without saying a word.
