Elemental mercury should be no problem at all, just siphon it out. Don't handle it as we use to as kids, we now know it can be absorbed thru the skin. But it won't dissolve in SW
. That was a old thermometer!
"Elemental mercury is toxic primarily through inhalation of mercury vapors. It is only slowly absorbed through the skin, although it may cause skin and eye irritation. Elemental mercury droplets may be absorbed through eye contact. Ingestion is not an important route of acute exposure as almost no elemental mercury is absorbed through the gastrointestinal tract."
