Mercury extraction?

The volume of mercury in a fluorescent tube is pretty small, you'd need a lot of tubes, and would generate a lot of contaminated scrap just to obtain dirty mercury. If you have a legitimate use for it I suspect you could buy some, no doubt you;d have to sign some forms and what not, but I'll bet it could be done. BTW, you might want to not be such a head when dealing suppliers and, especially, any regulatory authorities.
