Mercury is a liquid that conducts electricity. When heated up, this liquid expands, and vice versa. Does not kill STKM. One of the heaviest liquids, it can even sink below some lighter powders like DUST. It is almost indestructible since it can't catch fire or vaporize, but certain elements such as BOMB will cause damage.
