Roll it forward and it rolls right back! Discover the science behind potential energy.
Fifteen pieces of strong cardboard, a rubber band, a metal weight, and a small plastic cinch all build into a most fascinating example of energy conversion.
Follow along with the included building guide to piece it all together. Then push it forward and you’ll see how it creates reverse potential energy as it turns and then converts it into motion to bring it back to you!
