Super Solar Racing Car
If there’s one energy source more inexhaustible than your child, it’s the sun. The Super Solar Racing Car ($11) takes full advantage of this free and abundant power, converting it into fuel for the high performance engine in this tiny, yet shockingly fast, car. You have to put it together, but no tools are required, and it’s an easy build. Once it’s done, your little racer will endlessly fly around a track as long as the sun is shining.
