This little wind-powered toy brings clean, green energy to the palm of your hand, and is a great little gadget for getting youngsters interested in the beauty of renewable energy. No batteries or charging or nothing – instead just blow on the toy and watch it light up! The wind-powered toy has one green and two blue LED lights which are powered by blowing on the tiny 2.4-inch rotor blade. So you can forget using a lighter or cell phone during that ballad at your next rock concert— illuminate the night with the eco-friendly Blow Light!
