Unpacking Instructions You might have seen my work on Digital Trends, PC World, VentureBeat, or even the New York Times website. Reading a Galileo thermometer is quite simple. The accuracy of your thermometer will depend on a variety of factors. Under normal conditions, the … The most basic Galileo thermometers are simple glass tubes, but some may include barometers, hygrometers, or quartz clocks. Changing temperatures cause the colorful orbs to either sink or float inside the glass tube. The spheres float because the liquid inside the tube becomes denser than the spheres.

Galilei (1564 – 1642). Keep in mind that Galileo thermometers are not super precise. In this case, you'll need to take the average value between the lowest bulb's temperature in the top group and the highest sphere in the bottom group (the spheres directly above and below the gap). One last factor determining accuracy is how the spheres are calibrated. For the most accurate results, it's best to not hang the thermometer in direct sunlight. In stock on January 2, 2021.
