Crazy Clock by Maurice Janssen
You show a flat paper clock with missing numbers, numbers in the wrong locations, tilted at different angles. You have a prediction which sits out the entire time. You show a small packet of facedown cards, give them a shuffle and place them around the clock, next to the hours. Your volunteer calls out a number (or rolls a die) from 1 – 6 and begins counting from that number around the clock. They eliminate the card at that number and continue eliminating until only one card remains – which matches your prediction. For an added bonus, you show the eliminated cards faces are all the same……BLANK.
