Did Galileo make the Galileo thermometer?
Although named after the 16th–17th-century physicist Galileo, the thermometer was not invented by him. [Galileo did invent a thermometer, called Galileo’s air thermometer (more accurately called a thermoscope), in or before 1603.]

Did Galileo improve the water thermometer?
The first Water Thermometer was created during the 16th century. In the year 1593, Galileo Galilei made a better Thermometer which was basically a water thermometer. This newer version was the first type of thermometer to allow variations in temperature.
How can you tell if you have a Galileo thermometer?
Attached to each ball is a metal disc, stamped with the temperature. The temperature can be measured by reading the metal tag attached to the lowest of the floating balls in the top half of the thermometer. Galileo thermometers work on the principle of buoyancy, which determines whether objects float or sink.
What is the liquid in a thermometer?
In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.
What is the liquid inside of a glass Galileo thermometer?
What is the clear liquid in a Galileo thermometer? The clear liquid in a Galileo thermometer is ethanol, a colorless volatile liquid with very little odor. Although its density is less than water, it varies depending on the temperature, even more so than water.
What is inside of a Galileo thermometer?
The liquid in a Galileo thermometer is water. Floating in the water within the tube are glass bubbles also filled with water containing simple food coloring, though sometimes alcohol might be used. The Galileo thermometer is an accurately functioning machine that is more often than not used today as decoration.
What fluid is in a floating thermometer?
The clear liquid inside the Galileo thermometer is not water, but is another liquid, typically ethanol, whose density varies with temperature more than the density of water does. This makes it more sensitive to temperature changes which makes it a better predictor for temperature than water.
What to do if you broke a thermometer?
Slowly and carefully squeeze mercury onto a damp paper towel. Alternatively, use two pieces of cardboard paper to roll the mercury beads onto the paper towel or into the bag. Place the paper towel in a zip locking bag and secure. Make sure to label the bag as directed by your local health or fire department.
Can a glass thermometer stopped working?
However, if your thermometer has seemingly stopped working, you can repair it by placing the thermometer in a refrigerator or freezer. If it’s cold enough, it may restore the mercury column on your thermometer.
Is the liquid inside a Galileo thermometer toxic?
The liquid in AcuRite Galileo Thermometers is 100% paraffin. The colored bulbs are filled with paraffin and 3.4% dye. The liquid is non-toxic. The dye inside colored bulbs may stain fabric.
What if I touched mercury from a thermometer?
MERCURY EXPOSURE If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.
How do you fix a broken thermometer?
Heating–Heating the thermometer bulb is often the quickest and most successful method of repairing column separations. The heat can be applied by holding the bulb under a faucet of hot running water or by immersion in a pan of slowly heating water.
