Low Cost and Easy to Build DIY Pinewood Derby Track

I demonstrate an easy to build pinewood derby track that features mechanisms to release the cars and to designate the winning car. I only purchased a 1/4 inch sheet of plywood and used scrap wood for the rest. I looked and couldn't find anything similar so a am sharing my original design with the Boy Scout community. I had 3 boys in Boy Scouts so I built many cars over the years, but this is only my second track. Much more interesting than building cars:) One thing to note is that the speed of a particular car depends on the track design. If the track starts out steep and than levels out a car will be faster if the weight is centered in the back of the car. This is because there is more potential energy because the center of mass of the car will fall more during the steep portion of the track. If the track is a constant slope it really doesn't matter. Having the wheels well aligned is probably the most import consideration.
