Easy build-it-yourself solar eco house operates on natural sunlight or on batteries when indoors!
This super cool-looking house comes to life with an LED sign display, solar door sound, and solar windmill.
It's an eco-friendly DIY toy that provides hours of learning, and great to display when you're done.
The Greenex Series is 100% battery-free eco learning fun that connects the environment to amazing science experiments.Smartly designed, each
Greenex kit allows kids to snap the pieces together with ease. Simply snap all key components and modules together to start and then pull
apart once finished. Encourages kids to experiment on their own for additional learning. Best of all, each kit can snap to another to integrate
functions and double (triple, quadruple) the fun!
