Gallium spoon melts in tea

A soft silvery metallic poor metal, elemental gallium is a brittle solid at low temperatures. As it liquefies slightly above room temperature, it will melt in the hand. -wiki

This is very cool -- it must be the metal with the next-lowest melting temperature after mercury.

.....aaaaaand a bit of research reveals that Ga melts at 29.8°C, and there are three other "liquid metals" as well: francium (27°C), caesium (28°C), and rubidium (39°C).  Gallium is the only one that is considered non-toxic.

There are also non-toxic metal alloys that are liquid at room temperature, such as gallium-indium-tin, which melts at -20°C.

You must live in a very cold room


Melting at -20 means that it's still liquid at room temperature. It will stay liquid until the evaporation temperature has been reached, probably much higher than room temperature.
