Answer
The molten metal is mercury (Hg)!Mercury's melting point is lower than that of water and is a liquid at room temperature. It's got something to do with the very weak Hg-Hg bonding, and that's due to the fact that Hg atoms do not share their valence electrons readily.
Mercury is poisonous and should be handled with care. However, unlike other liquids, it doesn't stick to or infiltrate solid surfaces unless they're made of metals. Therefore, mercury poisoning is unlikely to be caused by skin contact.

People have been putting mercury in their mouths for years, they just usually encase it in glass - haven't you ever taken your temperature with a mercury thermometer? Also, during most od the 20th century, tooth cavities were filled with an amalgam of silver and mercury - are you sure you haven't been putting mercury in your mouth??
Simple but fun!!! Loved it!
It could also have been one of the metals that melts just above room temperature (but it doesn't burn).
loved this teaser
Don't try this at home the fumes are hazardous and the element is poison (it is found in some fish and shell fish)
btw - it is not molten as in applied heat it is in liquid state at room temperature
