BIOS Medical Weather 6” Galileo Thermometer Ornament

Everyone’s familiar with thermometers, but what’s a Galileo thermometer? Based on its name, most people would immediately assume that it was invented by Galileo Galilei, the historically famous Italian physicist, astronomer and inventor; -- which simply isn't true. The physicist happened to have a pupil known as Torricelli, and in a combined effort with his own team, they invented the Galileo thermometer.

For hundreds of years, these neat little devices were never reproduced. In the 1990’s, the Natural History Museum of London began selling its own version of Galileo thermometers through their gift shop.

As experts in the production of intelligent products, BIOS Weather now produces their own Galileo Thermometer as an ornament! As a gift and an ornament, it’s both practical and aesthetically pleasing, making it perfect for anyone during the holiday season.

Galileo Thermometer Description

The BIOS Weather 6” Galileo Thermometer Ornament features both Celsius and Fahrenheit tags, great for checking the temperature throughout the season as it hangs on your Christmas tree. These tags are marked according to the temperature they’re meant to measure and are denoted by their beautifully coloured liquids and markings on the gold-finished tag.

How Does a Galileo Thermometer Work?

As a part of gifting a Galileo thermometer ornament, you should know how it works so it doesn’t spark any confusion on Christmas morning. Traditionally, a Galileo thermometer is crafted out of a sealed glass cylinder containing clear liquid and a handful of small glass vessels.

Each of the glass vessels in a Galilean thermometer is crafted to be of a different density. This is achieved by calculating the approximate density of the material, filling it with water and a small amount of alcohol, then sealing it. At the bottom of each vessel is a tag which indicates the temperature. Upon reaching the top of the glass cylinder, that should be an accurate approximation of the temperature outside of the cylinder.

The inner workings of a Galileo thermometer aren’t dissimilar to a modern mercury thermometer. When there's a temperature change around the glass cylinder, the density of mercury changes, causing it to push up along the inside. Similarly, the temperature alters the buoyancy and density of the temperature-gauging vessels, causing them to either float or sink.
