Moana + forehead touches

The Hongi (or Honi) is a Polynesian greeting in which two people greet each other by pressing noses/foreheads and inhaling at the same time. This represents the exchange of ha, the breath of life, and mana, spiritual power, between two people. The ancient custom of Hongi when meeting another included touching foreheads together, inhaling, kissing the other on the cheek, hugging and then exhaling.

Imagine stabbing someone with this knife. 

It would instantly cauterize the would, so the person wouldn’t bleed, so it’s not very useful.

if you want information it is

and above, in order, we see a gryffindor, a ravenclaw, and a slytherin

why would you stab a PERSON when you can have TOAST?

There’s the hufflepuff

Polished Malachite Stalactite - Copper Crescent, Congo

*looks around*


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 don’t 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.

…sadly, I am not on good enough terms with any of our partner geologists to just attach this to an email with the subject line: “EXPLAIN.”

Although I think @mollisaurus is a mineral person. Thoughts?

oh geeze, i’m 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?

It’s really only a problem if you’re polishing or cutting it. The particles would be bad to breathe. It’s 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 it’s 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. 

malachite literally explodes in water does it not?

I… no… I think you’re 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 you’re getting all this information on minerals and rocks. You’re 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.

I’m still not sure if I can fuck this rock.

I’m looking into it.




Today in “I’m so sorry, coworkers, it’s for Tumblr,” I brought this post to the attention the science reporters at BuzzFeed. Dan Vergano did a some research and weighed in on the question “Can you use malachite as a dildo or is it toxic?”

The answer is “It’s probably fine, just wash it first and maybe use a bunch of lube.”

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 here’s 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.


• Malachite is not copper oxide. It’s Cu2CO3(OH)2. Like most carbonates it’s water soluble– that’s how it became a stalactite in the first place! And technically any given chunk of “malachite” isn’t just malachite– it’s 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 fungi– 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++.

• Malachite dissolves somewhat slowly in water– but vaginal secretions aren’t just any water. A healthy human vagina has a pH of 3.8-4.5 and a salinity of about 0.9%. It’s 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 “how fast does the human vagina dissolve malachite?” 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 there’s nothing to worry about. An encounter with a stalactite would have to last years for enough Cu++ to leach out to cause problems. If it’s quick then we’re in trouble. 

• Unfortunately it looks like nobody really knows. One of the best sources on how malachite dissolves & precipitates in water– an EPA document on how to avoid too much Cu++ in municipal drinking water systems– helpfully says “The kinetic constraints on the formation of these solids in water systems are largely unexplored” (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 don’t exist because nobody’s ever needed to know before. So we’d better assume it’s going to happen reasonably quickly, #for safety.

• So in best scientific fashion, we’re 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. 


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. He’s got no acidity in there, and again the salinity and temperature are slightly lower than people. But this is probably the closest we’re 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 you’ll get AT LEAST 9.12 x 10^-4 moles/L, or 5.8 ppm, of Cu++ at equilibrium. 

• Recall from above that most “malachite” isn’t actually pure malachite, it’s a mix of various copper carbonates & oxides. The EPA document elaborates: “[T]raditional ‘eyeball’ 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. … 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.”

In other words, “do your math and then double how much Cu++ you think is going to be in the water, just in case.” 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 “so 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?” 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*.

• Losing 99.7% of your vaginal flora is seriously bad news. You’re looking at really good odds of a yeast infection, bacterial vaginosis, and/or other infection issues. And that’s if you’re lucky enough to not be in the 4% of the population or so that’s sensitive to skin contact with copper

• The good news? Biochemically speaking, you’re probably ok to put it in your butt. It’s not as acidic or salty in there, plus there’s 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 it’s really interesting that the internet’s 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 Flint’s 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 River’s water is “corrosive,” leading many to believe the river is full of industrial waste. This ain’t the case. You’d need industry to fill a river with industrial waste, and industry left decades ago. That’s why Flint’s so poor. So what IS in the water? Road salt. Plain old stupid road salt. The old Detroit-based source didn’t 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. 

• 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

• Pls use a condom when fucking any water-soluble material

• Still don’t put the stalactite in your butt -3/10 do not recommend

OK, I haven’t reblogged this before now but the final post takes it to a whole new level and I can no longer resist. 

Yep writing a story about this

give me a grey makeup pencil and some white face paint and i could recreate the su*cide sq*ads look easily but do u know how complicated it would be for me to make the alien makeup of beyond? itd take years of training, and then weeks upon weeks of work to perfect the prosthetics, hours to put on the actors faces seamlessly………….im salty

You’re not the only one

This took 5 hours in the chair every day…shut up.

And I quote from the person who was the head of making the FIFTY SIX DIFFERENT aliens costumes.

“Each one of those characters had to be treated like a hero main character. On days when you had 20, 30 of these characters playing, you really had to have competent makeup application artists on-set to deliver them “

20 TO 30 on multiple days. 

For example

“For the generic characters, there was a lot of pieces, sometimes upwards of six, seven, eight silicon, overlapping prosthetics that you have to apply in sequence, and blend off, and then tie in the paint job or the patterning or whatever it is. I would think the shortest amount of time that anybody spent in the chair was probably two hours, and the longest was the Natalia character at the end of the film, and that was about six and a half, seven hours”.

So shortest. 2. Longest. SEVEN.

They spent hours, on JUST background characters. JUST THE BACKGROUND. Not even the main people. That is how much detail Star Trek put in.

For example!

Not to mention, the various stages Idris Elba had to go through. Because his wasn’t just one look. Krall’s face had multiple looks throughout the film.

And remember, there 53 other aliens I haven’t even mentioned.

Croc does look good. Can’t say he doesn’t OF COURSE he does. 

But for all that is good.

56 brand new aliens. 20-30 would be worked on on the same day, multiple times. 2 to 7 hours of work ON EVERY.SINGLE.ONE.OF.THEM.

Yeah, people are upset for a damn good reason. And telling to shut up over your croc when you haven’t even considered goolging is childs play. Not to mention!!! How it was revealed the sexiest votes SS got because of Harley Quinn!! Which means, the Oscars didn’t even care about Croc! [Source]

So please. Just don’t.

Do u ever not realize how starved for affection u are till someone hugs u a bit tighter than normal and you find that you really don’t want to let go

Touch starvation is actually a thing. The term for it that’s emerging in medical/psych circles is “skin hunger”. We as humans are meant to be much more social- and especially physically social - than we actually are, and Americans in particular are often touch starved because the casual, platonic contact that often happens between friends in other places just. Does not happen here.

There’s a really Puritan idea that’s pervaded our culture, that touch and sex are inherently linked, and it’s doing us a massive disservice. Touch is incredibly important for humans- hugs reduce blood pressure, cuddling releases oxytocin, and babies will straight up DIE without being touched enough because the stimulation releases hormones that are integral to their healthy development.

We were never meant to hold one another at arm’s length, and if you feel you need physical contact, don’t be afraid to ask for it! Hug your mom. Cuddle a friend on the couch. Ask. There’s a good chance that they need contact just as much as you do.

person: what’s wrong with you

me: i have the Skin Hunger
