Colorful Ball Nordic Creative Thermometer

The Colorful Ball Nordic Creative Thermometer from Comfyhaus is a Galileo thermometer: a liquid-filled glass cylinder with colored blown-glass balls suspended inside. As the room warms or cools, the liquid changes density and the balls slowly rise or sink. Each ball carries a small charm, and the lowest one still floating shows the temperature.

Every piece is purely handmade from blown glass, so the balls and their colors vary slightly from one to the next. It reads at a glance and needs no batteries or power, which makes it as much a desk or shelf ornament as an instrument. The simple, modern shape suits a bedroom, living room, or office.

It comes in four sizes, each with a different number of balls: 25x180mm with 5, 36x280mm with 7, 50x440mm with 10, and 50x530mm with 12. Taller cylinders hold more balls and give a finer read. Like all Galileo thermometers, it shows approximate room temperature rather than an exact degree, and the glass body is delicate, so give it a stable, level spot away from direct heat and sun.
