COOL PINEWOOD DEBY FACTS

• Did you know that each year over 2 million kits are sold and built in the United States? It is estimated that up to 100 million have been built since the mid-fifties.
• Did you know that while there are lots of specifications for Pinewood Derby cars there are very few specifications for the tracks they run on?
• Webelos Cub scouts are racing champions more often than other ranks. It's the experience! Tiger Cubs run a close second with the additional help they get from mom and dad. How about that!
• The favorite color for most pinewood cars is red, followed by blue.
• Did you know that 5 ounces, the maximum pinewood derby car weight, is equal to about 56 1/2 new (post 1982) copper-clad US pennies? The older bronze penny (95% copper/5% tin&zinc) is heavier and requires about 46 to equal 5 ounces. Because of the minting process variables and wear this is an approximate weight average.
• The best design for a fast car on one track may not be the best for another track due to slope, run-out, lane guide type etc.
• Good wheel lubrication and maximum mass in a low profile allows one car to pass another on the flat run-out portion of the track.
• Did you know that Pinewood Derbies began in Southern California in the mid-1950's?
• Did you know that a very thin car can actually run upside down and backwards?
• Some organizations have major competitions for design, unique concepts and appearance and may not race cars at all?
