About the Car

Our car is named Sparkle Pink because our car will glisten in the sun when it races down the track. We believe that our car is innovative and creative. Something special about our car is that we designed 3D printed wheels using Tinkercad. Also, the solar panel is angled perfectly to capture the sun’s rays. Some of the earth-friendly materials we used are parts of a yard sign and a bottle cap for the ping pong ball holder. We used the engineering design process to make our car. We improved our chassis by velcroing the solar panel, so it would be easy to angle or to place the ping pong ball in the bottle cap holder. We encountered some obstacles with our gears. The gears were not spinning very well at first, so as a team we decided to use different size gears to improve our car’s speed.
