I love this video for how it makes dangers of mercury poisoning real for people showing it instead of a lecture. It's also a good reminder of what I thought about mercury as a Christian: "that shit is from Satan!" Having one's mind deactivated piece by piece has to be one of worst fates for an intellectual individual and/or their family observing. I feel lots of sympathy for that woman and her husband. :(
It's so dangerous that industry mostly obsoleted it on purpose. It probably should be treated as a chemical weapon with anyone illegitimately selling it doing life in prison. I stay the heck away from anything with mercury if I can live without it.
