Features: This wind-powered toy is a great little gadget for getting kids interested in renewable energy. No batteries or charging. Just blow on the rotors and watch it light up. It has one green and two blue LED lights which are powered by the tiny 2.4-inch rotor blade.   Description: The worlds smallest wind generator! Blow on the rotor to light up the blue and green LEDs. The blow light comes in three parts to be pushed together: a white 6cm diameter rotor blade; 17cm long clear ABS plastic stalk; and the dynamo and LED housing. When the rotor blade turns it creates electricity to power two blue and one green LED (ideal wind speed around 6mph if used outdoors). Novel and educational, the blow light is a unique gift or a useful science teaching resource. Attractively and securely packaged. Not suitable for under 3s due to small parts.   Package include: 1 x blow light mini turbine
