Hi, I have to build a toy car that travels a distance of 31 feet, but the only source of energy must come from a size 10 rubber band and no more. I can twist the rubber band so when I release it, it will untwist and create energy to turn the wheels of the car<--- that was my idea but its not working very well because for some reason my rubber band wont untwist itself efficiently. Or we can stretch the rubber band to cause some sort of force to be released to push the car across the distance. We may also cut the rubber band to create energy. All forces coming from the rubber band must be internal, meaning no sling shots. The whole point of the project is to create a transmission of a car with an energy source to turn the wheels through the manipulation of a rubber band. Do you have any suggestions to help this project become a success? If so, please let me know. Thanks a lot! June
