Hi Sean,

Try this site: http://www.seps.org/cvoracle/faq/mousetrap.html which provides details for cars powered by mousetraps and rubber bands.

Rubber band powered cars are made either by winding the elastic band around an axle, or having it turn a small propeller on the back of the car to push it forward. See here for some more information http://www.seps.org/oracle/oracle.archi ... 14183.html

Mouse trap cars are made by having a mouse trap pull on a piece of string wound around an axle. See here for some more information http://www.msu.edu/user/fawcett3/cindyand.htm

Hope this helps, but if you need more help, just leave another message.
