If you’re looking for a cool way to educate your Transformer-loving kids about solar power, check out the T3 Solar Robot Kit.

Not only can you use this 70-piece kit to build a robot, you can then transform it into a tank or a scorpion! You won’t need batteries to power your creation – a healthy dose of sunlight will do the trick. Or, if the day’s cloudy, you can use a deck light to power up.

With the detailed instructions and a simple screwdriver, use it as a stress-relieving desk toy or enjoy it with your kids. It’s a great way to learn more about how alternative energy works, no matter the age.
