For example, many have a range of 60 °F (16 °C) to 100 °F (38 °C) and won't tell you the temperature if it's higher or lower than those values. If there is no bulb floating in the gap, use the lowest bulb from the floating cluster to get the temperature. Aye, there’s the rub. Changing temperatures cause the colorful orbs to either sink or float inside the glass tube. Conversely, if the bulbs all sink, then the air temperature is warmer than the reading on the highest tag. Last Updated: April 24, 2020 While you can't tell the exact barometric pressure using this technique, it will allow you to monitor trends. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Galileo's work inspired scientists and researchers at the Accademia del Cimento of Florence to create the Galileo thermometer in the mid-1600s. A simple, fairly accurate thermometer, today it is mostly used as decoration. It will expand and contract based on movements in temperature.

For the most accurate results, it's best to not hang the thermometer in direct sunlight. The spheres sink in high temperatures because as the liquid in the tube heats up, it becomes less dense than the spheres. When the barometric pressure increases, the spout's water will be low, and fair weather can be expected. Floating in the water within the tube are glass bubbles also filled with water containing simple food coloring, though sometimes alcohol might be used.
