Polished Malachite Stalactite - Copper Crescent, Congo
*looks around*
Is
Is anyone gonna say it
malachite is a poisonous mineral. please do not fuck the malachite stalactite
@lizaleigh do you know any rock people that can confirm/deny because I am very curious and really donât feel like getting into a conversation with my geophysicist brother that MAY somehow get back to the fact I saw a malachite that looked like a weird dildo.
âŠsadly, I am not on good enough terms with any of our partner geologists to just attach this to an email with the subject line: âEXPLAIN.â Although I think @mollisaurus is a mineral person. Thoughts?
oh geeze, iâm kinda rusty on minerals but malachite is just copper carbonate and is really common in both antique and modern jewelry so i think like if you were really gun-ho about it you could go ahead and put it wherever you want?
Itâs really only a problem if youâre polishing or cutting it. The particles would be bad to breathe. Itâs rather porous too, so I would worry about bacteria growing. Well, being literal anyway⊠Better to leave the poor thing alone. ._.
I mean it kinda depends on where you stick it because malachite does not like acidic environments very much and the malachite will degrade and also might dye your bits blue-green as the copper dissolves out.
So use a condom when fucking rocks is the takeaway here.
Oh my god guys itâs poisonous
It is super poisonous
There is a reason we do not use it in make up any more
Not even with a condom, do not fuck the rock
Try this one instead.Â
malachite literally explodes in water does it not?
I⊠no⊠I think youâre thinking of pure sodium?
Malachite is however water soluble, which really just means it will poison you quicker
This is both hilarious and cool as fuck because youâre getting all this information on minerals and rocks. Youâre also watching people argue over wether or not you can fuck this rock
I go on hiatus for a week and come back to find tumblr molesting my post, but hey, at least we all learned something so yay tumblr, you just keep on being you.
Iâm still not sure if I can fuck this rock.
Iâm looking into it.
UPDATE:
Today in âIâm so sorry, coworkers, itâs for Tumblr,â I brought this post to the attention the science reporters at BuzzFeed. Dan Vergano did a some research and weighed in on the question âCan you use malachite as a dildo or is it toxic?â
The answer is âItâs probably fine, just wash it first and maybe use a bunch of lube.â
Oh man this got so much better than the last time I saw this post
This is my favourite. Science side of tumblr: asking the REAL questions
*biologist crashes through the underbrush* Ok so hereâs the thing though Malachite is not poisonous to YOU. BUT fucking this stalactite will probably wreck your vaginal flora and leave you with a gruesome infection within a couple days. Want details? SO GLAD YOU ASKED, âCAUSE HERE THEY ARE. âą Malachite is not copper oxide. Itâs Cu2CO3(OH)2. Like most carbonates itâs water solubleâ thatâs how it became a stalactite in the first place! And technically any given chunk of âmalachiteâ isnât just malachiteâ itâs a mix of various copper carbonates & oxides. This will become important later. ⹠When malachite dissolves it makes a bunch of copper (Cu++) ions. Cu++ is GREAT at killing bacteria and fungiâ so good at it that sprays with Cu++ get used a lot as a spray in agriculture to stop plant disease. It takes such a large dose to harm larger organisms that copper sprays are used a lot in organic agriculture (like Bordeaux mixture). So bottom line, yes malachite is technically nontoxic to humans. But it kills bacteria when it dissolves and releases Cu++. âą Malachite dissolves somewhat slowly in waterâ but vaginal secretions arenât just any water. A healthy human vagina has a pH of 3.8-4.5 and a salinity of about 0.9%. Itâs also warmer than your average underground cave at 37°C (or 98.5°F in American meat units). As luck would have it, acidity, salinity, and warmth all make malachite dissolve faster. ⹠In other words, the human vagina dissolves malachite. ⹠I have no deeper explanation for why human females can dissolve rocks with our genitals. It simply is. ⹠Gonna to take a quick moment to point out that sex toys that dissolve when you use them are maybe not the best investment. ⹠Anyway the key question now is âhow fast does the human vagina dissolve malachite?â Are we talking geological timescale, a Nazis-in-Indiana-Jones situation, or something in between? If the reaction kinetics of dissolution are very slow, then thereâs nothing to worry about. An encounter with a stalactite would have to last years for enough Cu++ to leach out to cause problems. If itâs quick then weâre in trouble. ⹠Unfortunately it looks like nobody really knows. One of the best sources on how malachite dissolves & precipitates in waterâ an EPA document on how to avoid too much Cu++ in municipal drinking water systemsâ helpfully says âThe kinetic constraints on the formation of these solids in water systems are largely unexploredâ (p. 42) because end equilibrium points is all you need to run a city water system safely. In other words, the experiments that would tell us how fast malachite dissolves in various types of water just donât exist because nobodyâs ever needed to know before. So weâd better assume itâs going to happen reasonably quickly, #for safety. âą So in best scientific fashion, weâre just going to bullshit our way ahead using what facts we DO have on hand: endpoint equlibria. ⹠Is there any info out there telling us what equilibrium concentration of Cu++ we get in salty acidic water at body temperature? Almost! One J.F. Scaife published some great data on this back in 1957. TAKE IT AWAY, SCAIFE.Â
That orange box is how many moles of dissolved Cu++ Scaife got from sticking malachite in some water that had 0.171 moles NaCl/L (body salinity is about 0.154 moles NaCl/L so this is slightly less salty than people) at 30°C. Heâs got no acidity in there, and again the salinity and temperature are slightly lower than people. But this is probably the closest weâre going to get to data on how malachite behaves in vaginas anytime soon, folks. From this we can take away that if you leave malachite alone in a vagina youâll get AT LEAST 9.12 x 10^-4 moles/L, or 5.8 ppm, of Cu++ at equilibrium. ⹠Recall from above that most âmalachiteâ isnât actually pure malachite, itâs a mix of various copper carbonates & oxides. The EPA document elaborates: â[T]raditional âeyeballâ identification of malachite by its blue-green color is extremely unreliable, because almost all cupric hydroxysulfates, hydroxycarbonates, hydroxychlorides, and even fresh cupric hydroxide can be some shade of blue-green. âŠÂ Thus, the uncertainty in the computed copper concentration in equilibrium with malachite is at least about a factor of 2 ⊠until further experimental data focusing on this problem is generated.â In other words, âdo your math and then double how much Cu++ you think is going to be in the water, just in case.â So that gives us 11.6ppm Cu++, at equilibrium, with malachite in a (til now!) healthy vagina. ⹠Next step: do we have any idea what happens to bacteria in acid conditions with copper? OH MY GOD WE TOTALLY DO. Gyawali et al 2011 checked this out in the context of âso what if we rinsed tomatoes with a solution of lactic acid and copper, because that would be a safe & organic way to get rid of E. coli?â So now this post has officially ruined stalactites, vaginas, and tomatoes.
^This would happen. These are the counts of 4 E. coli strains exposed to various levels of lactic acid & Cu++ for 8 hours. This table only shows the end counts but it represents the death of 99.7% of bacteria*. âą Losing 99.7% of your vaginal flora is seriously bad news. Youâre looking at really good odds of a yeast infection, bacterial vaginosis, and/or other infection issues. And thatâs if youâre lucky enough to not be in the 4% of the population or so thatâs sensitive to skin contact with copper. ⹠The good news? Biochemically speaking, youâre probably ok to put it in your butt. Itâs not as acidic or salty in there, plus thereâs a huuuuuge stockpile of gut microbes right upstream that can quickly repopulate the colon after spelunking is complete. However this stalactite is not flared at the base so it is the wrong shape for putting in your butt. Do not put this stalactite in your butt. ⹠This all looks like fun and games, but I think itâs really interesting that the internetâs mistake in concluding that this stalactite is fuckable is very similar to the mistake made by the Flint water management system. Hear me out. ⹠Central to the Flint lead poisoning crisis is that authorities only looked at & tested Flintâs water in its central treatment plant before it went out through the pipes. Not after it went through the pipes. They did not consider what would happen biochemically as it went through the pipes and metals started dissolving. ⹠Similarly, in concluding that the stalactite is fuckable, the internet only considered the stalactite itself. Not the biochemical processes that would happen to it as it, welp, went through the pipes. ⹠Media frequently reports that the Flint Riverâs water is âcorrosive,â leading many to believe the river is full of industrial waste. This ainât the case. Youâd need industry to fill a river with industrial waste, and industry left decades ago. Thatâs why Flintâs so poor. So what IS in the water? Road salt. Plain old stupid road salt. The old Detroit-based source didnât have salt because it came from Lake Huron which has a large, mostly rural watershed. Meanwhile the Flint River runs through a lot of towns, making it slightly salty as everything melts down in spring. And as we recall from the stalactite experience, a little salt is all it takes to get metals to dissolve. âąÂ Information on this engineering problem was not coming through clearly from the engineering or chemistry sides. It took a biologist, pediatrician Mona Hanna-Attisha, to document the real-time results and provide the data to kick-start a high-level investigation. ⹠Morals of the story: when dealing with a biological system pls consider asking a biologist, your vagina and/or city could depend on this âą Pls use a condom when fucking any water-soluble material âą Still donât put the stalactite in your butt -3/10 do not recommend
OK, I havenât reblogged this before now but the final post takes it to a whole new level and I can no longer resist.Â
This might be the most Tumblr thing Iâve ever seen.

REBLOG IF YOU HAVE STRETCHMARKS

Y u pet me
Keep pet me
This always makes me happy, because the source video shows that the shark actually wanted this. It experienced it once and then kept coming back for more petting.
(also, because iâve seen comments about this: the shark is able to breathe while still, not all species need to be in motion to pass water through their gills. If you look closely, you can see its gills pumping)
I would very much like if more people would pet sharks and be good to them instead of trying to hurt them please
Sharks are very lovely and should get pettings like these more :)
MythBusters did an episode on how to survive a shark attack and a sharkâs nose is so sensitive that a gentle tap is all you need to drive it away. The guy sat on the ocean floor with a bucket of chum and didnât get attacked once, when hungry sharks swam up heâd give them a boop on the nose and theyâd swim away. So if the shark is friendly, pet the snoot. If the shark is dangerous, boop the snoot. Either way, no one dies.Â
Boop the snoot
