Mercury vapor is odorless, colorless and very toxic. Even though liquid mercury evaporates slowly, a significant amount of mercury vapor can build up indoors after mercury is spilled, and it can be dangerous to breathe these mercury vapors.
Mercury only becomes solid at temperatures below 37.89 degrees Fahrenheit. Mercury becomes a liquid at room temperature. Mercury is very weird. It attaches to metal, but bends over plastic. It is poisonous if used wrong. It is used in thermometers.
