Fascinating 17-piece experiment kit to explore eco-friendly engineering.
Build your own energy efficient home with this cool STEM kit. Follow along with the 32-page manual as you assemble a 14-inch model, complete with wired LEDs and appliances. Collect sunlight and convert it into electricity, then experiment with a water pump for heating. Watch as the lawnmower "mows" your grass and grow a nifty living roof too!
