Rube Goldberg #3

We have changed our whole sketch. It now includes more simple machines, each step is changing from KE (kinetic energy) to PE (potential energy), and it is a lot more interesting. The simple machines we are using includes a lever, ramp and wheel and axle. We finished the sketch and are happy with the way it turned out, and we didn’t even have to scrap our old pieces we built for the other sketch. We are using them in our new design. I will update you more when we start building again!
