When I was young there were plastic maze toys with a drop of mercury inside.
Years ago I had an environmental activist knock my door. His agenda was that his organization wanted tighter government controls on mercury emissions. I wasn't particularly interested at the time.
When it comes to poisons, concentration is everything. What could be deadly in one dose could also be harmless in trace amounts. Chemical structure is also important.
