Radiometer

This might be a thoughtful gift for anyone interested in science-y type stuff.
Invented in the late 1870s by chemist Sir William Crookes, a Radiometer is part science project, part conversation piece. Housed inside a glass bulb with a partial vacuum, the four vanes of the Radiometer are attached to a delicate stem, which rotates when it senses the presence of light. The brighter the light, the faster it spins. The bulb is perched on a thin glass stand that evokes both a chemistry lab and a wine glass. Place one on your desk, on the living room coffee table or even on the kitchen window sill, and it will offer quiet meditative movement as the room’s light changes and shifts. Made in Germany.
