Perpetual Motion - Free Energy

I made this for my science project on renewable energy. Its a perpetual motion machine known as an overbalanced wheel... Bhāskara's wheel to be exact. It took a ton of work to get just right; I had to clean and grease the bearings several times, water wasn't heavy enough so we had to dissolve a TON of salt in the water to increase the weight, and then we had to tape coins to the wheel in several spots to get the wheel as perfectly balanced as possible.
