About This

• How it works - The glass Radiometer is made of a vacuum glass bulb. There is a rotating shaft and four blades inside. When it is exposed to sunlight, artificial light, or infrared radiation, its leaves will rotate. The stronger the light, the faster it rotates.
• Exquisitely designed - Handmade from high-quality glass. Crystal clear, small and exquisite. It needs to be placed on a flat surface to prevent shattering.
• It is a creative gift, we can send it to our friends or family.They will love it!
