For this project we were trying to make fuel efficient car designs with no electricity whatsoever. We decided to go off the main road of using balloons or rubber bands to make a car that would go 1mph, and decided to make a towering, pulley powered, monster of a car. The main idea for this car was to have a pulley at the top of this car which had a string run through it. The string had a weight attached on one end and it wrapped around and axle at the other. When the weight is dropped, the string unwinds the axle and makes the wheels spin moving the car forward.

Reflection
Overall, I think that I had an amazing group for this project. We were all friends and we all worked well together. One thing that we did well in this project is that we tried to stay away from the normal solution to the problem and make something that hasn't been done before. We also communicated very well. If one person had an idea or concern, everyone else would listen and take into mind what they were saying. One thing that we didn't do well in the project is we didn't manage our time that well. We started a car and kinda slacked off for a while in class, but then we were able to pull it together in the end and go to my house to finish it. Another thing we didn't do so well on is that we had some talking issues. Sometimes we would be talking about our car, then after ten minutes we would end up talking about something completely irrelevant.
