    Re: Artificial horizons and mercury
    From: Paul Hirose

    I remember playing with a Petri dish of mercury in school back when I
    was about 10 years old. We students were allowed to stick our fingers
    in the mercury and float coins on it. There was no personal protective
    equipment for us at all.
    
    That was back in the 1960s. Times have changed. A few years ago, a kid
    broke a mercury thermometer in a classroom so they evacuated the
    building. The Los Angeles TV stations covered the hazmat spill
    response with live video from copters hovering overhead. Of course
    with my experience I was thinking, "get a LIFE, people!"
    
    Mercury *is* pretty nasty, though. Put the words
    
    mercury msds
    
    in a search engine and take a look at some of the material data safety
    sheets. No more touching mercury bare-handed for me!
    
    This web page on handling mercury in the lab is pretty good:
