Handcrafted from high-quality tinted blue glass, this delicate ornament contains a partial vacuum glass bulb housing a lightweight spindle with four spinning vanes. When exposed to direct sunlight, artificial incandescent light, or infrared radiation, the vanes automatically rotate without any batteries or electricity. The dark side of each vane absorbs heat, creating a thermal force that propels the spindle; the brighter the light source, the faster it spins. It serves as an engaging educational tool to demonstrate thermodynamics and solar energy conversion. Perfect for home decor, office tables, bookshelves, or a sunny window sill, this unique physics toy is designed for older children and adults who appreciate sophisticated, interactive design.\u003c\/p\u003e","brand":"DORAMI","offers":[{"title":"Default Title","offer_id":52031762563389,"sku":"Rudra-B079CL6XBF","price":3439.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0991\/7602\/2333\/files\/padded_1774011173.jpg?v=1784891511","url":"https:\/\/rudraretails.com\/products\/dorami-blue-solar-power-crookes-radiometer-windmill-4","provider":"Rudra Retails","version":"1.0","type":"link"}
