These curious and mesmerising instruments measure the power of electromagnetic radiation. Made from a glass bulb with much of the air removed to form a partial vacuum, inside is a set of fine metal vanes, each with one dark and one light side, mounted on a spindle. The vanes rotate, as if by magic, when exposed to sunlight, artificial light, or infrared radiation (even the heat of a hand nearby can be enough) – the more intense the light, the faster the rotation.

Sadly, It Does Not Rotate Even In Strong Sunlight.

I have just tried it again in fairly strong sunlight and it does not rotate at all. Our daughter bought me a similar one about 30 years ago and that whizzed around in any sort of light until it gave up the ghost a couple of years ago. This was meant to be a replacement. I think the item must be defective.

Great Purchase

I sent this to my son as a surprise (we had been talking about Radiometers, although l didn't know that was it's name) as he was fascinated by one we had at home years ago. He's had a rough time, was furloughed and recently made redundant. It arrived extremely promptly and well packaged. He loves it!
