4M GreenScience Solar Mechanic

With the Solar Mechanic kit, you can learn about alternative energy using solar panels and hand cranks. This kit uses repurposed materials. Product Description Assemble a unique solar motorized module powered by a solar cell - using clean energy from the sun. Use it as the engine of a vibrating robot that slides across the floor, a cooling fan that functions automatically under the sun, an illusion spinner that turns the sun's rays and colours to sparkling visual wonder, and more. No batteries are required. The fun and the power are unlimited. How to power your solar machines indoors or when there is no sunshine? Shine a desk lamp directly onto the solar panel from close up. The light should be enough to drive the solar machines indoors. Note: Not military grade (obiviolusy for this price.)
