I first learned of them in my high school physics class and vowed I'll own some of my own. I even pictured having a room in a house one day that gets lots of light, full of different looking radiometers.
I liked them so much I was mesmerized. I got caught in the hypnotic spin of the radiometer. Somehow one radiometer made its way from the science room into another classroom and I just stared at the radiometer all during class. See, I can't even remember what class I took in that room since I only paid attention to the radiometer.
Unlike some childhood dreams that never came true, my dream of owning radiometers has come true.
:-D
This was the first radiometer I bought. I can still clearly remember finding it. It was at the Somerset Mall in Michigan that I went to while I was visiting my aunt during a college holiday break. And I knew it was meant to be, because it was on sale! This radiometer sat proudly in my college dorm, spinning and spinning and it has travelled with me from abode to abode ever since.
My husband has added to my (now our) collection since, and while I won't post every single one we have, here's one of my favorites, a hanging 3 parter.
But there's one radiometer I really want that I can't even find a picture off the internet to post here. It is a double-radiometer. It's a standing radiometer like the first one, and it has two bulbs one right on top of the other. And the vanes in the bulbs spin in opposite directions. One of these days I'll find it, and it will be mine!!!!
PS. If I remember my physics class correctly, scientist aren't 100% sure what makes radiometers spin! There's various theories, but nothing proven. Pretty cool if you ask me!
