How Do You Make A Rubber Band Propelled Car?
Rubber band toy cars are one of the simplest self-propelled toy cars that you can make at home. It is a simple process that takes about an hour. The car operates due to the stored (potential) energy created by wrapping the band around the axle, changing into motion (kinetic) energy as it unwraps. The longer the rubber band you use, the faster and farther your car will be able to go. Also, by changing the size of the wheel you can affect distance and speed, so try different combinations, and have fun. Notch the body. Using the scissors, cut a notch in the center of the 5-inch side of the cardboard. The notch needs to be 1½ inches deep and 2 inches wide. Throw away the piece that you cut out. Make the axle. Slip the wooden skewer through the cardboard, near the outer edge of the notch. The skewer must be equally distributed on either side of the cardboard, or the car will drive crooked. If the skewer doesn’t rotate freely, turn it manually a few times to widen the opening a little bit. M
