If anyone else was reminded of that video of a 110lb anvil floating in a tub of mercury, here you go. Don’t try this at home.
didn’t they use to use shitloads of mercury for floating the lenses on a lighthouse, letting it turn without too much in the way of friction?
That’s right, I often forget about that.
Anyone who’s studied high school physics will also remember one of the biggest blunders of modern experimental physics: the Michelson-Morley Experiment which infamously attempted to prove the existence of the aether but rather gave them a pretty clear confirmation of a lack of the aether. It actually ended up helping form one of the basic tenets of Einstein’s Special Relativity, which is that the speed of light is constant within an inertial frame of reference.
They floated their interferometer setup on a sandstone slab measuring 1.5m x 1.5m x 0.3m in a giant circular trough of mercury in order to provide near-zero friction and reduce vibrations.
Not only is this technique still used to insulate large optical devices such as telescopes but liquid mercury is even spun around to create mirrors for telescopes: https://en.m.wikipedia.org/wiki/Liquid-mirror_telescope
Nine out of ten hatters recommend that you don’t do this. The tenth hatter purple monkey dishwasher.
(Victorian-era hat makers were notorious for going mad because they used mercury to treat felt cloth.)
I wonder what secondary compounds this was creating. Elemental mercury is pretty much fine, but if it was reacting with other things to create wacky fun times…
I think it was mercury nitrate. Much more soluble.
they chewed the leather to hides to soften them, IIRC. so it wasn’t just getting on their hands, they were ingesting it.
Is this the origin story of The Mad Hatter? 🙄
I think the original idiom was “mad as a hatter” which was eventually shortened to “mad hatter”, possibly due to the Alice in Wonderland character.
Could have been. I know Lewis Carroll liked to lampoon issues of the day in his writing.
I’m kind of guessing the mad as a hatter phenomenon was known then, but don’t really know.
Sneaky Simpsons reference here for those who didn’t notice.
It’s so much harder believing in six impossible things before breakfast when you’re allergic to quicksilver.
I wondered what the Mercury actually did with the felt, as I couldn’t think of anything from the top of my hat:
Mercury made the felting process in hat production more efficient. The compound used to moisten the fibers was Mercury Nitrate, a process known as carroting. It produced a superior-quality felt, which in turn, resulted in higher-quality hats
Mercury Nitrate
Which, should be noted, is not the mercury show in the picture. Mercuric nitrates are a white/yellow dry powder that is the result of mixing mercury with nitric acid. The process of making mercuric nitrates, and carroting itself, both result in rather toxic fumes that you really should not breathe in.
Handling liquid mercury is basically almost harmless as it absorbs through the skin really slowly and doesn’t produce much vapours. Putting it in acid, heating it up, and putting the cloth treated with it in an oven is not.
I thought it was the vapours from using mercury inside that got them.
Sure is hand outside today
Delicious as Sunny D.
I can’t read this. Reported.
Rip to that guy
Mercury can absorb through the skin, but it takes a very long time. (Generally safe to touch it, but still wouldn’t recommend it)
If you have the stuff in your bare hands you also inhale the stuff…
You could just… not inhale liquids you’re holding in your hands. Probably a good idea even when it’s not mercury
/s
Try telling that to a 🐠
Metallic murcury can’t actually be absorbed through the skin, and it can theoretically be handled without protective equipment if you know what you’re doing. Not that I would recommend it.
See the crazy stuff that Cody’s Lab does on YouTube, and he hasn’t gotten poisoned yet:
My friends Dad showed us one time handling it in his hands, he said you just have to be absolutely certain you have no cuts or injuries that would let it get to your bloodstream. That was a long time ago now, today’s parents would probably freak.
Mercury poisoning isn’t all or nothing. I love love love Cody but also that boy probably has a little mercury poisoning at this point ngl.
No he’s been tested and the test came back normal
Holy shit. I’m as surprised as I am happy! Thanks for letting me know.
Ooo I forgot about Cody. Gotta see if he is back to posting videos
He just published a few videos, with more about the Chicken Hole Base
He’s back and posting fairly regularly again, and better news is that he finally got paid by Google!
Is it more the inhalation than the skin absorption that would be toxic? Not too familar with mercury poisoning.
You’re correct
Nah, it’s the vapor that’s dangerous with elemental mercury. Touching it is basically fine. Just no open wounds and be in a well ventilated area
There are far more toxic forms of mercury you shouldn’t mess with though
Dads old mercury filled carburetor sinch worked much better than the oil filled one ever did.
Toxic as fuck.
Not as much
Metallic elemental mercury (what you see in the picture) is relatively harmless to touch. Arguably, it’s more dangerous to rub a lead ingot, for example. However, mercury vapours (and mercury does evaporate slowly but consistently) absorb quite easily when you breath them with a ton of undesirable effects, often related to central nervous system, which is never a nice thing. Broken mercury thermometer won’t kill you. Playing with the puddle inside a non-ventilated room might kill you in several decades. Working in the non-open-air environment where mercury is always present will slowly worsen your health as mercury accumulates.
Organic compounds of mercury are what actually is nasty. A short contact with a few millilitres of that — and you will have to recover for a long-long time, if ever. However, the scary stories about methylmercury rarely mention that there are other organic compounds that are just as toxic or worse. I wouldn’t get close to any organic cadmium compound, for example, and would be extremely wary of its inorganic salts too. The thing is it’s extremely unlikely that you encounter any of these chemicals ever in your life, and if you do encounter them, then you are likely a professional who knows exactly how and why you are to deal with them.
From the same issue:
Is, uhh… Is he floatin’ on a pool of mercury?
That he is. Looks like fun, right?
Honestly he looks a bit anxious
Pure mercury metal is pretty chill, just done fuck with organic mercury compounds
Vapours too.

Oh, he be Madden alright.
This kills the idiot.
Is no one going to comment on the font rendering
When I was young my Dad bought me some mercury home from work… I loved how it moved when I shook the bottle and the weight of it.
When I had my own kids I didn’t want it around, so our local council had set up a event where you could dispose of household liquids like old paints and solvents, so I took it down. When I drove up, the guy asked me what I was disposing of so I said mercury. It was bizarre. I was told to stay in the car and a guy came out of a shed in a full hazmat suit with one of those pairs of metal tongs to retrieve it from me.
I remember Dad telling me that miners used to collect gold pan tailings in mercury and then of a night they would hollow out a potato and put the mercury in, and then put that in the camp fire… it would burn off the mercury and leave a little ingot of gold.
Out in the edge of the lower mainland of BC by Hope, where there was a mini gold rush a long time ago you can find lots and lots of mercury sitting below the water levels when the streams dry out during the summer.
It is all left behind from the miners back in the day.
That sounds like it would look really lovely. Got any pictures?
Mercury sitting below the ground level sitting underground, potentially poisoning the ground water if it gets disturbed enough is beautiful or just the area of nature where the gold panning happens?
It’s actually harmless if not ingested. They were being weird.
Its also harmless, generally, when ingested as the gastrointestinal absorption of elemental mercury is negligible. It is inhalation that is most concerning with elemental mercury.
Except eating paint chips with lead made a lot of kids dumb. Lead based paint held up awesome, but it was banned due to injection. Not inhalation. Even now, 40+ years later it’s still the leading cause of lead poisoning in children.
I mean… we’re talking about mercury here, not lead.
Oh, fuck me. Lol. I commented last night and then responded back today and in between my mind totally flipped to thinking it was about lead.
We also had an innocent looking little (maybe 100ml or 200) bottle of mercury at school. Mostly for the startling weight when it was passed around to demonstrate density.
Probably because they didn’t know WHICH type of mercury you had. Organic mercury can kill on touch with a single drop. Best not to take chances.
Yeah. Elemental is mostly harmless if you aren’t around it for long and don’t inhale vapors.
Source? I’m not sure who to believe. People on the internet who claim it’s safe enough that you can pick it up or people on the internet who claim kills you if you touch it.
I’m not going to go swimming in a mercury pool any time soon either way.
I think they are saying it depends what you mean by “mercury” because some compounds are both toxic and readily absorbed through the skin.
Exactly that. Elemental mercury (ie: the liquid metal form) doesn’t readily absorb through the skin. It gives off vapors which are harmful with extended or repeated contact, but generally it’s not super dangerous to be around.(Not totally safe though)
Organic mercury compounds (eg: methylmercury) are extremely toxic because they can be absorbed through the skin, and can traverse the blood brain barrier
Regular liquid mercury is relatively safe to handle, but I would still wear gloves. It won’t get through undamaged skin, but is dangerous if you have even a small skin laceration it can get through.
Chemist here. Organometallic compounds of Mercury are primarily dangerous because Mercury ions bond fairly strongly to soft ligands like sulfhydryl groups found near the active sites of enzymes. This can result in the displacement of the metal ions or otherwise disrupt the structure needed for enzyme functionality. Mercury metal OTOH is considerably less reactive. It is not safe to breathe in for prolonged periods of time but it is no where near as toxic as its organometallic derivatives are. Dimethyl Mercury for example, is extremely dangerous. A single drop has 100+ times the organomercury content needed to kill someone.
you can always consult the Material Safety Data Sheet
For comparison, dimethyl mercury
Elemental mercury is not going to kill you if you touch it- wash hands and call a doctor. they’ll probably be like, “Take two asprin and call me int he morning so I can bill you twice.” you definitely don’t want to inhale it, but outside of something like a fire or being heated, adequate ventilation is sufficient; if ventilation isn’t possible a respirator is a good idea. Dimethyl on the other hand… is nasty.
I had to search for “organic mercury”, it’s dimethylmercury and it doesn’t look like mercury at all. Do people really call it “mercury” or “organic mercury”? It’s on par with pounds as a measure of mass, weight, and force by the amount of confusion, I’d say 🤔
sad story
that was in the top of search results about dimethylmercury:
sad but also a bit ironic fate 🫡 that’s why I prefer not to do dangerous things even when protection and/or safety is in place.I think chubbyemu did a video about this lady. Absolutely tragic and heart breaking.
And currency!
Forgot about that, this certainly
adds insult to an injuryspices it up

No, I doubt it. There aren’t very many uses for dimethylmercury due to its potential lethality. I would assume the people who actually use it in a lab setting are going to call it dimethylmercury, especially considering organic mercury usually refers to methylmercury, or one of the other less harmful organomercury compounds.
I think the confusion probably stems from the original article about the scientist who passed. Dimethylmercury is made from a reaction of methylmercury, and they are both organomercuric compounds.
