It needs to be placed on a flat surface to avoid shattering. How it works - The glass radiometer consists of a vacuum glass bulb with a rotating shaft and four blades inside. When exposed to sunlight, artificial light or infrared light, the blades rotate. The stronger the light, the faster they rotate. BEST DECORATION - Suitable for office, living room, bedroom, classroom, study room, party and other occasions. Place it on the desktop or windowsill, as long as there is enough light, it can rotate continuously without needing other energy. CREATIVE GIFT - Perfect as a gift for family, friends, colleagues and leaders. As long as there is light, it can rotate continuously, just like our emotions. As long as we treat it sincerely, friendship is eternal. Physics Teaching Tool - Its formation can explain many physics principles, such as the principle of refraction of light, the principle of air friction, the principle of vacuum propagation of light, the principle of uneven heating, the principle of electricity generation, etc. Product Introduction: Radiometer is an educational and physical demonstration object invented by British physicist Crooks about 100 years ago. Today, radiometers have become home decorations and holiday gifts, and of course, teaching tools in physics. How does it work? Radiometers consist of a partially evacuated glass bulb. Inside are four vases mounted on spindles. The vanes rotate when exposed to sunlight, artificial light, or infrared light.
