Watch sunlight come to life inside glass!
The Solar Radiometer is a captivating scientific instrument that demonstrates how light energy becomes motion. Sealed inside a beautifully crafted blown glass globe, the vanes spin as sunlight or bright indoor light heats them. With alternating black and white surfaces, the vanes respond differently to light—absorbing and reflecting rays, resulting in movement powered entirely by the sun.
Place it on a windowsill, under a lamp, or in a classroom to observe the power of radiant energy in action. A timeless favorite for science lovers, teachers, and curious minds.
