Quicksilver

Mercury is the only metal on earth that is liquid at room temperature. Since mercury looks like shiny liquid silver, it is sometimes called quicksilver. Mercury is used for many different things around the world. It is used to mine or extract gold from ore, which are rocks that contain metals like gold. Mercury is also used to make or manufacture different things like computer monitors and fluorescent lights, and it is used to make dental fillings. Because mercury expands or gets bigger when heated, it is also used in thermometers. As the temperature rises, so does the mercury.
