1.14 second Pinewood Derby Car!!! (CO2)

Retired engineer, Joseph Hodgson, decided to build a Pinewood Derby car a few years back that broke the rules a bit and used a ducted fan for propulsion. It wasn't fast enough. The next year, he build a direct-drive car that was faster but still not quite there. In 2011, he nearly broke the 1 second barrier with his latest...a CO2 powered beauty. The speed is one thing but watch the whole video for a good look at the intricate detail involved in the creation of this masterpiece.
