What fluid is in a floating thermometer?
Answer: The clear liquid inside isn’t water, it’s ethanol.
Is the blue liquid in a thermometer dangerous?
The blue spirit thermometers listed contain non-toxic isoamyl benzoate and dye. These thermometers can be stored horizontally; their separation rate is equal to or better than mercury thermometers.
What liquid is in non mercury thermometers?
The alcohol thermometer or spirit thermometer is an alternative to the mercury-in-glass thermometer and has similar functions. Unlike the mercury-in-glass thermometer, the contents of an alcohol thermometer are less toxic and will evaporate quickly.
Do Galileo thermometers have mercury?

What are the dangers of a mercury thermometer?
The small silvery ball in a mercury thermometer can be dangerous if the glass breaks and the mercury is not cleaned up properly. The mercury will evaporate and can contaminate the surrounding air and become toxic to humans and wildlife.
Can a liquid thermometer be used to measure temperature?
Mercury and other liquid thermometers cannot be used to measure temperatures in kelvins. Kelvin thermometers are usually electric devices that can record tiny variations in radiation. These variations would not be visible and may not change air pressure enough to raise the level of mercury in a liquid thermometer.
Are there laws against the sale of mercury thermometers?
Some states and municipalities have passed laws or ordinances barring the manufacture, sale and/or distribution of mercury fever thermometers. This is to help remove the threat of thermometer breakage and the subsequent release of mercury vapor indoors.
Do you have to touch your body to use a thermometer?
Touch, or contact, thermometers must touch the body in order to measure temperature. Remote, or no contact, thermometers can measure body temperature without touching the skin. The most common kind of contact thermometer uses electronic heat sensors to record body temperature.
