Recruit two volunteers by asking for students who are metal heads. For this game you need two pedometers and two headbands. I purchased a pedometer for $5 at walmart and a wilson headband for $2. The pedometer had a belt clip that we ran the headband through. Place the pedometer clipped to the headband around the forehead of each volunteer. Give them one minute to register as many steps as they can by head banging. We used Metallica’s “Enter Sandman.” The one whose pedometer measure the most head banging wins.
