Bring a little sunshine to your shelf. This authentic vintage solar radiometer features four diamond vanes (two black, two mirrored silver) suspended in a hand-blown glass bulb on its original cream pedestal base with a cheerful smiling sun and "SOLAR POWER" text.
Place it in direct sunlight or under a bright incandescent lamp and watch it spin — no batteries, no cords, just physics doing its thing. The stronger the light, the faster it goes. Perfect for a windowsill, desk, science teacher gift, or that mid-century curiosity cabinet you're building.
From the era when science toys were made to last, this one has the wonderful patina and slightly yellowed base that collectors love. Works beautifully — spins readily in sun.
