hongher2005 Posted February 1, 2008 Report Share Posted February 1, 2008 Im in the 7th grade doing an engineering fair project! Im making a rubber band powered car.. I have sort of an idea of how I want to make it. I think I'm going to make it out of legos for less weight then put 2 straws for the wheels to spin to reduce friction. Then large wheels with a lot of grip for max acceleration.. But the thing I can't get is how to get 1 rubber band to turn it all and move it.. please help! Thanks! if you want more info, the accual rules and regulations are at --- http://www.ospe.org/associations/7506/files/2008%20Official%20Rubber%20Band%20Powered%20Vehicle%20Rules.pdf --- Quote Link to comment Share on other sites More sharing options...
