Pendulum

 We began trying to make a yo-yo but we discovered the device had to be self  sufficient . So we decided to make a pendulum. We soon realized that this was not possible because the bean couldn't swing in a circle this being discover we renamed our pendulum a swing. our device consist of paper in the shape of a triangular post that we then hung a paper clip on the top of the post and attached sting. At the end of the sting we attached another paper clip and we taped two beans to a small piece of paper. In order to get the device to move we had someone lift the paper clipped bean to give it a downward momentum.Thus our swing was created.Our device was somewhat successful but not recommended.
