I have 6 Uncles and their sons along with my Brother, Father and Grandfather. I have married in Aunts as well who participate. I however am the only girl granddaughter and I would like to win this thing!!! Of course my first thought is search the internet for amazing tips....right? The problem is that they ALL search the internet. They are really crazy with their graphite, weights and little secrets! I also should mention that I come from a family of jewelers so they have any tool imaginable to drill, shape or create their car. I am looking for some expert physics or aerodynamics secrets. Something...that none of them would be able to find searching the internet. I know its a long shot but does anyone have any mathematical or engineering genius they could send my way. Any secret websites, surefire tips or designs? Last year I tried a C02 cartrige on one car. I was evidently the most creative but couldn't win cuz pinewood derby has specific guidelines! Thanks so much!!
