  I saw that, too (or is that three)... I also saw something similar today (or yesterday), a melted metal led thingy, and it got me thinking about making my own mercury tilt switch (perhaps an idea for someone doing the recession prop contest... Grandma may have an old mercury thremometer in the medicine cabinet).

  Be careful.
  
  Mercury is considered a serious bio-hazard now. I was talking to my local fire chief a couple
  months ago, and he said that if he *knew* there was open mercury somewhere he would have
  to roadblock the area, and call in a special hazmat team to bring equipment to clean it up.
  (This was actually done once, someone broke an old thermometer in a desk in city hall.)
  
  Funny, how many of us played with it coating pennies as kids. The rule was to wash your
  hands after you were done playing with it. (At least in my house) Outside of my serious
  addiction to all things electronic, I've suffered no ill effects.

  I played with it quite a bit as a child as well.
  
  My theory is that eating lead paint and sliding down slides into playgrounds full of arsenic-laden materials counteracts the mercury.
