Galileo Thermometer
2.1
How the Galileo thermometer works
The Galileo thermometer consists of a sealed glass tube that is filled with water and several floating
bubbles. The bubbles are glass spheres filled with a colored liquid mixture.
Attached to each bubble is a little metal tag that indicates a temperature. These metal tags are
calibrated counterweights. The weight of each tag is slightly different from the others. Since the
bubbles are all hand-blown glass, they aren't exactly the same size and shape.
The bubbles are calibrated by adding a certain amount of fluid to them so that they have the exact
same density. So, after the weighted tags are attached to the bubbles, each differs very slightly in
density (the ratio of mass to volume) from the other bubbles, and the density of all of them is very
close to the density of the surrounding water.
As the temperature of the air outside the thermometer changes, so does the temperature of the water
surrounding the bubbles. As the temperature of the water changes, it either expands or contracts,
thereby changing its density. So, at any given density, some of the bubbles will float and others will
sink. The bubble that sinks the most indicates the approximate current temperature.

How to read the Galileo thermometer
Make certain the weather station is installed on a flat surface. The lowest temperature bubble within
the group at the top of the cylinder displays the current temperature.
The lowest floating ball indicates the current temperature.
If all of the balls float to the top, the temperature is below the lowest floating ball.
If all of the balls sink, the temperature is above the highest ball.
