Volta Racers are pint-sized, solar powered DIY toys that are built for speed. Fueled by an on-board flexible solar panel, the cars require no batteries to juice-up the drive train. And with a chassis constructed of recyclable materials and an axle made of bamboo, this car is green… and modular to boot. The adjustable frame and chassis “allows you to experiment with two different solar panel configurations and two speed gear modes.” And because the parts snap together, junior builders can utilize the panel and motor in ways outside of the car’s packaged design (such as a giant solar cockroach, or USB charger). Volta racers are available in shades of blue, black, gray, green, pink and white. These toy cars are sure to have kids racing to learn more about renewable energy.
