For this challenge, you will build your own rubber band car. Rubber bands are stretchy, so you can "wind up" your car, and use the energy contained in the stretched rubber band to make your car go forwards. There are lots of ways to take advantage of rubber bands to move an object further! See instructions and video tutorial below to see one idea of how to build the car. What could you make your car out of? What can you modify, change, or add to make your car travel the farthest.
