Tell someone's fortune. Hold the fortune teller in your hand and have them choose a color. Open and close the device one time for each letter in the color. Next, have them choose a number and then open and close the fortune teller the correct number of times, based on their number. Finally, have them choose one more number, lift the selected flap, and read the fortune.
People's names, animals, or any theme can be incorporated into the fortune teller for a little variety.
