High Quality Content by WIKIPEDIA articles! The pinewood derby is a racing event for Cub Scouts in the Boy Scouts of America. Cub Scouts, with the help of parents, build their own cars from wood, usually from kits containing a block of pine, plastic wheels and metal axles. With the popularity of the pinewood derby, other organizations have developed similar events, and a small industry has developed to provide tracks, timers, scales and other products. The pinewood derby was selected as part of "America`s 100 Best" in 2006 as "a celebrated rite of spring" by Reader`s Digest. Similar Cub Scouting events include the raingutter regatta with boats and the space derby using rubber band powered rockets.
