It's that time of year when kids and their parents are starting to work on their cars for the pinewood derby. I've noticed an increasing trend in people coming to my blog by some form of Google search like, "pinewood derby humvee."
Let me just remind you from last year's post: Humvees are NOT aerodynamic and will NOT win the race (if that's what you care about). If you don't care about winning the race and just want to make something that looks cool, then totally go for it!
After our resounding defeat last year, I explained the basic concept of aerodynamics to ES. This year, ES decided he wants to make a bullet train for his pinewood derby car. We worked on it a bit today - got the basic shape cut, sanded it down, and put the first coat of paint on it. I'll post pictures later when it's done.
