Mercury has a number of uses. A small amount of mercury is present in all fluorescent lights, including compact fluorescent lights. In vaporized form, it creates a conductive pathway for the electric current to flow. Mercury is also part of an alloy called amalgam, which is used by dentists to fill cavities (although non-mercury fillings are also available now). Mercury is a solvent for gold, and has been used to create gold paint; when the mercury evaporates, a gold deposit is left behind. Because mercury is so dense, it is sometimes used when it is necessary to float heavy objects, for example, in the design of the Michaelson-Morley experiment which led to Einstein's theory of relativity. Mercury is sometimes used for its antibiotic properties, for example, to preserve vaccinations.
