Gallium metal, liquid under very dilute hydrochloric acid
Gallium metal has a tendency to supercool below 29 C (84 F),and can remain a liquid at 20 C (68 F). Here is a globule of liquid gallium at around 21 C (70 F) under very dilute hydrochloric acid, which dissolves the oxide layer giving the metal similar appearance to mercury (more concentrated acid can attack the metal).
