'Inversionist' schoolboy Frank Balek writes upside-down and back to front on a blackboard; a mirror at the top of the board shows us the words the right way around ("My name is Frank Balek"). Frank stands beside his teacher at the board as she reads out a mathematical sum. Frank writes each number on the blackboard upside-down, adds them together and gives his answer - correct!
