Manatee Maniacs

Photo & Basic Info

We are the Manatee Maniacs from Timber Lakes Elementary in Orlando, Florida. Yes that’s right, we are crazy about manatees and that is why we named our car after these friendly sea cows. We used green friendly materials such as a Gatorade lid to hold the ping pong ball and recycled cardboard pieces for the manatee’s snout and tail. We also repurposed a yard sign for our solar panel supports. We positioned our solar panel perfectly to catch the sun rays.

Another unique feature of our car includes our 3D printed rear wheels and the ombre painting effect on our chassis. A challenge we encountered was we had to use exact measurements for our axles. So, we decided to add beads to help the wheels spin properly. Don’t forget to be “green”, not mean.
