this is our current product.

After showing it to Micheal and Eugene they all bring up a problem which is the car automatically stops itself because the rubber band is stuck on both sides after is finished with the rotation it does not fully use its energy. Mr Hussack said that maybe we can look into how toy cars work. Also, sunnie(who is also doing a rubber band car) told us that the most probable way is to just not let the rubber band be tied to the engine, only to the car.

our plan is to tear the rubber band off. set the anchor to somewhere further ahead and not tie the engine this time.
