A little science, a lot of charm.

The Hightide Radiometer (S Size) is a classic scientific curiosity turned into a playful decorative piece. When exposed to direct sunlight or a warm light source, the black and silver vanes inside the glass bulb begin to spin—showcasing the delicate interaction between light and motion.

Compact in size, it makes an eye-catching desktop accessory, conversation starter, or thoughtful gift for the curious at heart.
