Kenny, are you gonna draw that in ascii for us? How about an avi
on your web site? :-)

Kidding aside, I like the thread on merc handling. At school, we
use a syrenge that normally lives on a bed of charcoal granules,
as does the merc supply. Being at the university, we have easy access
to toxic waste for the tubulation and electrodes that have had
contact with merc. We even use latex gloves (sometimes).

My home waste company also has periodic toxic
waste collections; I hope the reset of the country does as well.
I suspect one day we will have a toxic waste curbside recycle bin
to go beside our mixed paper bin , glass bin, plastic bottles bin,
actual trash bin, newspaper bin, and the yardwaste bin. Of course,
we composte the garbage!
