Your cart is empty.The sun’s energy can be used to do some pretty astonishing things! Get ready to explore the amazing capabilities of solar energy by building your own solar-powered vehicles and devices. Using a system of ultralight bamboo rods, plastic gears, and a powerful solar panel, you’ll build five different motorized models that that move using electricity generated directly from sunlight. Construct three types of solar cars, a solar fan, and a solar robot. Perform science experiments with each model to learn about gear ratios, solar cells, and more. The ultralight materials make your models speedy and durable while the modular gearing system lets you test out three different gear ratios.

Was amazed how much incident light you need to turn the motor.Really only works in Summer and outside. Failing that, you have to smother it with a bright light.Wheels spin on hard surfaces such as tiled floors or laminate.

Cheap parts, an under powered motor that barely turns the gears, and odd/poor designs (for marketing itself as "stem"). Do not waste your money on this. Far superior products out there.

I bought this product for my son's birthday and regret this purchase. Some of the bamboo sticks were thinner than it should be, so the wheels were not stable and the cart was floppy. We tried couple designs and each has its own problem. The assemble process was frustrating and was hard to do by a child. My son was able to try one of the design, but got a wood stick chip into his finger nail. I would not recommend this product.
