Defy gravity with the Greek Waiter's Tray! This device will allow you to observe the effects of momentum, friction, and centrifugal force. Place a glass on the tray and grip the apparatus by the top of the pendulum. With practice, you will be able to swing the tray from side to side (and even over your head!) without any spillage.
