I remember as a kid in country school putting some mercury in the palm of my hand and rubbing pennies in it to make them shiny and look like dimes. Back then it was just considered a fun liquid metal to play with.

    long time,
    not knowing it could go right through my skin.  Yikes!!
    Yikes indeed!  You have reminded me that I played with the mercury
    out of a broken thermometer when I was little.  I probably touched
    it to see it dissipate into little globules, though my mother did
    tell me how dangerous mercury was.
