Made in Germany, entirely by members of the Glass Art Guild of Thuringia.  What we may remember as a classic physics experiment becomes beautiful handcrafted kinetic They consists of an airtight glass bulb containing a partial vacuum, with a set of vanes which are mounted on a spindle inside. The vanes rotate when exposed to light, with faster rotation for brighter light.
