June 21, 2015 Morris Arboretum's SteamPunk Day:
ColonialLUG demonstrated the power of potential energy at the Morris Arboretum STEAMpunk Expo 2015. The Power It Up station demonstrated the mechanics of stored power. Using Technic bricks and gears, as well as rubber bands, we built pullback race cars that visitors could customize and then race to see how well they work. Visitors built everything from two-wheeled dragsters, to a three-frame combination vehicle. It took several people to pullback, but it worked! Everyone had a great time!
