Best Galileo Thermometers

Galileo thermometers are a fun decorative piece that measure the air’s temperature with rising and falling glass bubbles filled with colored water or alcohol. Reading a Galileo thermometer is easy: simply read the temperature tag on the lowest floating bubble. The more spheres a thermometer has, the more accurate it will be. The most basic Galileo thermometers are simple glass tubes, but some may include barometers, hygrometers, or quartz clocks. Aesthetics are important, and there are few Galileo thermometers that aren’t eye-catching, but if you’re concerned about the functionality of a thermometer, look for one that works consistently and accurately.
