You can't go wrong with the price either, which is considerably cheaper than some other Galileo thermometers we've seen. AcuRite offers a one-year warranty on this thermometer and barometer, and while it's quite large at 13.1 x 9.5 x 5.6 inches, it weighs less than two pounds and can be placed just about anywhere that has a flat surface. The water level in the spout of the glass globe reveals the variations in barometric pressure. While you can't tell the exact barometric pressure using this technique, it will allow you to monitor trends.

\u00a9 2021 wikiHow, Inc. All rights reserved. However, it also produces various other weather instruments, including this Galileo Thermometer with Glass Globe Barometer. Water is never used because liquids like ethanol show a more significant change in density as its temperature changes, making the thermometer more sensitive (and therefore more accurate). As I've found out on my own, weather stations aren't cheap, and it's easy to make a costly mistake. Changing temperatures cause the colorful orbs to either sink or float inside the glass tube. Dec 26, 2015 - A Galileo thermometer operates on the principle of buoyancy, the phenomenon by which objects of greater density than their surroundings sink and less-dense ones float. Using a beaker of water is great for a classroom demonstration because the temperature change between the air and the water makes for a dramatic show.
