Best Answer

Thermometers used to have Mercury in them because it is very temperature reactive and a liquid across most temperatures measured in everyday life. However, this practice has been discontinued due to the health risks associated with contact with Mercury from broken thermometers; most analog thermometers today use colored ethanol as the measuring fluid.
