The Pinewood Derby is an annual Cub Scouts activity in which boys build miniature wooden cars with their parents or adult mentors and then race the cars. Held annually since 1953, the activity intends to help boys enhance collaborative work skills, develop good sportsmanship and value tradition.
The official Pinewood Derby website has instructional videos for six different car models and sells car kits, tools, paints and other materials for making the cars.
