Rube Goldberg #3

After my partner and I finished the sketch, we realized that we only had one simple machine, which was the inclined plane. We had to start with a brand new piece of paper and started the sketch again. First, we thought of making a pulley. We thought of making it with a tape roll and string. We realized that there would be nowhere to hang the pulley, so we thought of a different simple machine. While it was Winter Break, I thought of trying to make a lever and a wheel and axle. After Winter Break, we tried looking for materials to make the lever and the wheel and axle. For our wheel and axle, we used a toy car, and for our lever, we used a tinfoil roll and a plastic lid.
