[math-fun] Q: Where do we get mercury?
A: H. G. Wells. When I was a kid, at least two friends had a bottle of Hg in their garage. I don't know why. We often played with it, smearing it on pennies, e.g.. If we spilled it, we could sweep it up and put it back in the bottle. I had numerous medical relatives who kept lots of mercurochrome and merthiolate. (AKA the infamous autismogenic thimerosal.) And we all had amalgam fillings. Rich and Hilarie named their daughter Mercury! "Almaden" is still a popular place|business name around San Jose, where the natives used cinnabar for warpaint. And the paper is still Mercury News. DHS might be interested in people trying to make the fulminate, but *much* more interested in the terror potential of the nightmarish compound methyl mercury, from which even a hazmat suit might not protect you from slow, agonizing braindeath. Fear of spontaneous formation of methyl mercury probably fuels today's mercury hysteria. —rwg When bottom-feeders ingest too much mercury, they can't get off the bottom.

Someone brought liquid mercury to one of the high schools in L.A. a few years ago, and the officials evacuated the school and brought in people in hazmat suits to remove any possible mercury spills. Irony alert: they apparently didn't realize that a much bigger mercury poisoning threat existed within every fluorescent bulb in the school.
The problem with a mercuryball is that it isn't "smart" or self-powered.

If the ball were flying through the air, it could set up asymmetric drag and change its trajectory to some degree. Even if it weren't *guided*, it could still move in a random and impossible-to-predict manner which would thoroughly confuse even the best goalies.

When I was a graduate student at University of Texas, I was assigned to run the sophomore physics lab one year. It was in one of the older buildings and the second floor lab had a wood floor, on which lots of mercury had been spilled over the years. When the problem was recognized a few years earlier, the solution mandated was to always keep all the windows open in that room, and the door closed. It gets pretty cold in Austin in the winter. A lot of times students could see their breath and heavy jackets were common. Brent On 2/10/2019 3:47 PM, Bill Gosper wrote:

Dimethylmercury is far more toxic than methyllmercury. There is quite a bit of information on this nasty chemical, including the death of Karen Wetterhahn.

My Dad worked for Kodak. He told me that once a mercury thermometer broke in the street internal to the industrial park where photographic paper and film were made. A small amount (maybe single atom?) can mess up the silver halide grains enough to make a visible spot on developed paper or film. So the risk was so great they dug up the street and trucked away all the asphalt and dirt! A guy has a nice YouTube video about mercury amalgamating with aluminum: https://www.youtube.com/watch?v=IrdYueB9pY4 <https://www.youtube.com/watch?v=IrdYueB9pY4> He also has ones with gold leaf and with sodium. I think mercury hacking is best done vicariously! — Mike

There is a rumor/urban legend about military throwing knives with mercury-filled handles. Don’t ask me where I heard this – I just have a mind like a vacuum cleaner that sucks up everything and spins it around. I think Bill means to refer to the neighborhood/place is short for Almaden Quicksilver. There is a good amount of mercury ore (cinnabar) in that ground and during the gold rush, several small mining towns were built to process it. At that time, there were no vents to prevent the processors from inhaling mercury fumes and the symptoms of mercury poisoning (losing teeth, hair loss, “softening” mind) were a known hazard. I used to take homeschooled kids into Almaden Quicksilver park and have them pick up the reddish rocks to see how heavy they felt and to see if the red could be scratched. There is also a defunct mercury processing plant within the park that closed down in the 1970s. And there is also an Almaden Lake (a separate park) in which you can fish but are strictly warned not to eat the fish you catch because the lake was a former cinnabar quarry naturally filled in by rain and run off (though the public – including myself – can and do swim in the lake).
