Description of Copernicus - Radiometer

Radiometer Another oldie but goodie. 5" high evacuated clear glass stand 3" in diameter at the top. A four bladed vane is balanced on a needle inside the sphere. Because opposite surfaces of the vanes are black and white, incident radiant energy is absorbed or reflected to a different degree. The result is a spinning vane. The brighter the light, the faster it spins. Simple, but compelling. Brief explanatory instruction sheet included.

Tools and Hardware Reviews of Copernicus - Radiometer

Customer Review: Classic Toy, Still Awesome!
Summary: 5 Stars

This is wonderful! I remember when I was a kid, and had one of these. It is not exactly fun to play with actively all the time, or something that you will be using every day to check lighting conditions, but it is definitely something to put on your window sill, or on a dresser or book shelf where it can be hit with the sun. I find it more of a decorative piece.

It is good to see these are still being made and sold! I bought two, and they both arrived VERY well packaged, in perfect condition, and work great! They also come with a little workbook with scientific experiments that can be done with them, and explanations of why it spins. Useful to teach with!
