Have you heard of the Galileo thermometer? The stylish glass cylinder is not only an unusual eye-catcher, but also a useful temperature gauge for your home. Here‘s how it works: the liquid thermometer made of glass contains colorful spheres that float in a transparent liquid. The famous physicist Galileo Galilei recognized as early as the end of the 16th century that the density of liquids changes with temperature. When warm, the liquid in the thermometer expands and you can see how the floats sink. However, if the temperature decreases again, the smaller spheres gain buoyancy and rise. Simply ingenious!
Accurate temperature measurement: Seeing the colored balls sink or rise is of course not enough to determine the temperature. However, this is what the metal plates on the buoyancy bodies are for. The metal plate on the lowest ball tells you the current ambient temperature between 18 and 26 degrees Celsius.
Excellent as a gift: The standing thermometer not only makes natural scientists happy, but is also an ideal gift for anyone who loves unusual decorations. The liquid thermometer is made of high-quality glass and will be an eye-catcher in the living room, bedroom or home office.
