As you know, we are a pinewood derby family, and while all the boys love it, Callahan has always shown the most interest. So it made perfect sense choose a derby theme when it came to his science fair project. The goal of a derby is to finish fastest ... how can you do that? Decrease FRICTION, increase speed ... now there are oodles of ways to reduce friction in your car... he chose to focus on using graphite to lubricate the wheels and axles. After running the experiment, the conclusion was that lubricating your wheels/axles makes a BIG difference and should definitely be done if you want a chance at winning the race!
