Description

  • 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.
  • The best decoration - It is suitable for occasions such as offices, living rooms, bedrooms, classrooms, study rooms, parties, etc. Place it on a desktop or windowsill, and as long as there is sufficient light, it can rotate continuously without requiring any other energy.
  • Creative Gift - Giving it as a gift to our family, friends, colleagues, and leaders is perfect. As long as there is light, it can rotate continuously, just like our emotions. As long as we treat them sincerely, friendship can be eternal.
  • Physics teaching tools - their formation can explain many physics principles. For example, the principle of refraction of light, the principle of air friction, the principle of vacuum propagation of light, the principle of uneven heating generating power, and so on.

When you put the radiometer in the sun, the vanes will keep spinning.
