The Soap Box is a youth soapbox car racing program which has been running in United States since 1934. Each July, the World Championship finals are held at Derby Downs in Akron, Ohio. Cars competing in this event are are unpowered and it relies completely upon the gravity to move.
The All-American Soap Box derby began the Rally World Championship in 1993. The Rally derby is a grand prix style of race in which each district sends back a number of champions based on number of racers and races in each district. Today there are broader categories that extend the age range to younger racers and permit adults to assist in construction. This is especially helpful for younger children who cannot use power tools, as well as to provide an outlet for adults.
