Hypothesis

I think putting more weight in the back and sanding the wheels will make the biggest improvement in speed.  I also think that making the car with an aerodynamic shape will help. (My Dad doesn’t think the cars go fast enough for the wind to make a difference.)

I think the cars will go slower when graphite is first put on the axles, and then get faster after a few races.  (Once when I was in Cub Scouts, I lost against one car, but then won the next time I raced him.)
