Ask the spectator to secretly select a random number from the sheet you display which has many different numbers printed on it. You write 16 different numbers in a grid that’s printed on a piece of white cardboard. The secretly chosen number is not included in what you write. But you’ve actually made a magic square using the spectator’s number!
