The science behind making the fastest possible Pinewood Derby car
You wouldn’t think that a four-wheeled car would go faster if one of its wheels didn’t touch the ground. Or if its axles were bent. Or if it was designed to grind against a wall. But you’d be wrong, and here’s the science to prove it. Our old friend Mark Rober—former NASA JPL engineer—has put together an exhaustive video on how to make the very best Pinewood Derby car. Full disclosure, I’d never heard of Pinewood Derbies—wherein Cub Scouts and Boy Scots make little cars and race them down a straight track—before this, but apparently they’re quite popular. Over 100 million cars have been made over the last sixty years.
