Pinewood derby on roids


Like pinewood derby? Want more speed than gravity can provide? Try CO2 rocket cars. Pitsco's Science of Speed site offers all kinds of info of the competitions, the techniques, the science, and the kits. The photo is Alan M's Muffin, which places 12th in the 2008 middle school competition.
