Invent a compass made of beams to draw circles on a cardboard sheet. Cut a hollow disc with a notch for the rubber band while the other end is held within your hand. Release the rubber band to project the aerodynamic disc and let it bounce against a wall or the ground. Make a series of discs with different sizes and experiment.
