Mercury clean up

[Ken]

I broke a small tube with mercury in it and caused a nice scatter around a basement room floor. I've scooped most of it up, though I know there are small hard to see pin-head sized pieces left lingering. How dangerous is this really? And what is the best way to get them up; cotton balls, etc..?

I have to hit the sack. Any advice is appreciated.



Thanks guys & gals.
