Galileo thermometer liquid glass thermometer – precise temperature display 18–26°C – 33 cm height, colourful spheres, for living room & office

Have you heard of the Galileo thermometer? This elegant glass cylinder is not only an extraordinary eye-catcher, but also a practical temperature gauge for your home. Here’s how it works: The glass liquid thermometer contains colourful spheres that float in a clear liquid. As early as the end of the 16th century, the famous physicist Galileo Galilei discovered that the density of liquids changes with temperature. When it gets warmer, the liquid in the thermometer expands and you can see the floating bodies sink. When the temperature drops again, the smaller spheres gain buoyancy and rise. Simply ingenious!

Accurate temperature measurement: Merely watching the colourful spheres rise or fall is of course not enough to determine the temperature. That’s where the metal tags on the floating bodies come in. The metal tag on the lowest sphere indicates the current ambient temperature between 18 and 26 degrees Celsius.

Perfect as a gift: This standing thermometer not only delights science enthusiasts, but is also an ideal gift for anyone who loves extraordinary decoration. The liquid thermometer is made of high‑quality glass and becomes a highlight in the living room, bedroom or home office.
