High-Tech Pinewood Derby Track Resolves Race to 0.00005 Seconds

When I participated in the Pinewood Derby as a Cub Scout, the winner was determined (I think) by snapping a string at the end of the track. Now a company called BestTrack has brought the race into the 21st Century. Its track uses an infrared beam to determine the winner. This system is accurate to one half of one hundred thousandth of a second.
