Two Rock 4-H SET met at Leghorns Park, Petaluma CA to build solar race cars. We had a spectacular day of beautiful sunshine (great for solar cars), and warm weather. We learned a lot about solar cars, like you need to point the solar panel into the sun for maximum speed. The "Sun E Zoom" car kit from Pitsco was a fun solar car to build. The solar panel was high quality and they included several different gears to experiment with.
