Using a CO2-Powered Pinewood Derby Car Is Probaby Cheating

The Pinewood Derby is a traditional crafting event among Cub Scouts in the United States. Boys are given a block of wood and some plastic wheels. Their job is to carve and paint the block into a car that, when released at the top of a long ramp, will beat the other similarly made cars to the finish line. When I was a Cub Scout, my Dad showed me how to add weights to the body. Doing so was completely within the rules. Adding CO2 canisters to the car, however, probably isn't. It's actually a fairly sophisticated modification because the tubes have to open at the right time. A video at the link shows how it's done.

What Krikkit said; there are Pinewood Derby cars and there are CO2 racers, and this isn't the former.

@Hiller: The Pinewood cars could weigh no more than 5 ounces. The winning cars always used a combination of clean aerodynamics and smooth-running wheels to win. Running straight also helped, because having the wheels bump against the track edges slows the car considerably. Those were some fun projects!

When I used to enter these races in boy scouts the derby cars were always carefully weighed by officials before they races, so that they met but did not surpass the weight limit. Forgot what it was, but it wasn't that much. It looks like this car did away with most of the wood, enough to have two CO2 canisters and still be within the weight allowance. Kudos.

Are you sure that is a Pinewood Derby car?

We also had C02 drag races in scouts. In that event, obviously, co2 canisters were allowed in the cars.

Bragging: MINE WON TOO!
