You can only eat 2 foods for the next 2 years (with no health repercussions)
Spin this wheel twice to figure out what they are!
Are you happy with your new food palette?
Literally a dream come true
Pretty satisfied, all things considered
It's fine I guess...
Ugh. I'm counting down the days until this ends
I FUCKING HATE THIS 😤 AAAAA

Please reblog and add your nationality in the tags along with what you answered! I'm very curious about this; and it's not to shame anybody, so don't be rude!
If you don't do the reblog part it's not very good as a study 😭
So fun story about my roommate
so last semester, my new roommate, without consulting anyone else, put up these stupid wall stickers. and I had to live with em alllll year.
(ignore the tapestry, that's mine)
so, end of the school year starts coming up, we're gonna have to take the damn things down anyway. so I decide to have some fun with it.
on sunday, while roomie was away at work, I took the stickers off the wall and started cutting up the letters. and this was what she found when she came home.
this was just above the couch, the first thing you'd see upon walking in the door. and my favorite of all, in the corner where the couch met the wall:
the next day, while I was in class, she came home and saw it. and promptly began acting like I did not exist.
It was the greatest week I'd had since moving in.
but only a week. one day, I texted our collective roommate group chat that I was taking an online test, and that I'd need quiet for about 2 hours or so. and when I finished, I left my room to find bare walls where my art once was, and a ball of letters in the trash can.
so I fished it out. and left this.
but I wasn't done quite yet. I fished out a couple favorites and put them back up in my room (partly bc I had gotten a bit attached to nut,)
now, you might notice that "tit" has lost its "s". that s now serves a greater purpose:
forming the word "penis" that I hid on the wall behind the couch before I moved out.
suffice to say, that roommate hasn't talked to me since.
I'm sorry but it's literally impossible to ignore the tapestry
has any cryptid ever been bullied harder than goatman. shane and ryan stole his bridge, ruined his reputation, and he didn't even get a shout out on their top 5 beatdown ep devoted to cryptids. lmao
I KEEP FORGETTING TO POST THINGS
A TTRPG where the setting is vaguely based on the 19th century and the character classes are Cowboy, Samurai, Detective (think Sherlock Holmes), Mad Scientist (think Jekyll or Frankenstein), and Hunter (specifically a monster hunter, think at least half of the anti-Dracula polycule). You can play as a human, vampire, werebeast, or something like Frankenstein’s monster. There are no restrictions on class-species combinations, so if you want to play Sherlock Holmes But A Werewolf or Vampire-Hunting Frankenstein’s Monster, you can do
rb this with ur opinion on this shade of pink:
This is magenta, and not pink. Unlike pink, magenta doesn’t actually exist. Our brain just invents magenta to serve as what it considers a logical bridge between red and violet, which each exist at opposite ends of a linear spectrum.
TL;DR this color is fake (and also I hate it)
Wait til you learn about Stygean Blue
Your brain is a badly-designed hot mess of bootstrapped chemistry that will tell you that all kinds of shit is happening that has no correlation to physical reality, including time travel. It just makes things up. Your brain is guessing about what’s happening when your eyes saccade, what’s happening in your blind spot, and what the majority of the visible light spectrum looks like, and you don’t know it’s happening because it doesn’t aid your survival to become aware that a lot of what you see is fake.
The human eye only has three types of color sensitive cones, which detect red, blue, and green light. Your brain is making up every other color you perceive.
Let’s have a little fun with that thought. This is the visible spectrum of light.
You will of course note that yellow is on the chart. Yellow has a discreet wavelength, and is therefore a distinct physical color. But we can’t see it.
“Sorry, what the fuck?”
What we call yellow is just what our brain shrugs and spits out when our red and green cones are equally stimulated. We have light receptors that can pick up on the physical spectrum of light we call yellow: that’s why yellow things don’t just look like moving black blocks to us. But your brain has no fucking idea what the color yellow looks like.
Some animals have eyes that can perceive the color yellow! Goldfish have a yellow cone in their eyes. If they could talk, they could tell us what yellow looks like. But we wouldn’t be able to understand it.
What your brain actually sees of the color spectrum:
We can measure the wavelength of light, so we know that when we see ‘yellow,’ we are seeing light in that 550-ish nanometers range. But we don’t have a cone in our eyes that can pick that up. Your brain just has a very consistent guess about what color that wavelength of light could be. We decided to name that guess ‘yellow.’ We can’t imagine what yellow really looks like any more than a dog can imagine the color red.
Here’s the funny thing: your brain is never perceiving just one photon of light at a time. Something like 2*10⁸ photons per second are hitting your retina under normal conditions. Your brain doesn’t individually process all of them. So it averages them out. It grabs a bunch of photons all coming from the same direction, with the same pattern, and goes, “yeah, that cup is blue, fuck it, next.”
That’s how colors blend in our eyes. So sure, if a photon of light with a wavelength of 550 nanometers bounces into our eyes, we see what we call “yellow.” But if we see two photons at the same time, coming from the same object, one of which is 500 nms and the other of which is 600 nms, your brain will average them out and you will still see yellow even though none of the light you just saw was 550 nms.
So how does magenta factor into this?
Well, as we’ve just established, when your brain sees light from two different slices of the visible light spectrum, it will try to just average them together. Green plus red is yellow, fuck it. If it’s more red than green, we’ll call that ‘orange.’ Literally who gives a shit, we’re trying to forage over here. There are bears out here and it’s so scary.
What happens if you take the average of blue and red light, which we perceive to be magenta? What’s the centerpoint of that line?
Fucking green.
Hey, that’s not gonna work? We live on a planet where EVERYTHING IS GREEN. If something is NOT green, that means it’s either food, or a potential source of danger, and either way your brain wants you to know about it.
So your brain goes, WHOOPS. Okay - this is fine. We already made up yellow, orange, cyan, and violet. We’ll just make up another color. Something that looks really, really different from green.
And so it made up magenta.
So, physics-wise, is magenta “real?”
No; there’s no single wavelength of light that corresponds to magenta. But you’re rarely seeing only a single wavelength of light anyway. And even when you are, every color other than RGB is a dart thrown on the wall by your meat computer. This is the CIE Chromaticity Diagram:
Explaining this thing is a little more than I want to take on on a Saturday morning, but I’ve included a link above that goes into it a little more. The point is that only the colors that actually touch the ‘outline’ of the shape actually correspond to a specific wavelength of light. All of the other colors are blends of multiple wavelengths. So magenta isn’t special.
Given that color is just a fun trick your brain is playing on you to help you find food and avoid danger, is magenta real?
Yeah, absolutely. Or at least, it’s just as real as most of what we see. It’s what we see when we mix up blue and red. It would be disastrous from a survival standpoint to perceive that color as green, so we don’t. Because it’s not green. Light that’s green has a wavelength of around 510 nm. Stuff that’s magenta bounces back light that is both ~400 and ~700. Your brain knows the difference. So it fills in the gap for you, with the best guess it has, same as it does with your blind spot.
The perception of color exists within your brain, and your brain says you see magenta. So you see magenta.
So I googled Stygian Blue and…
Yall.

Anyone on the team ever work with/around bonobos? They're my fave great apes
I have never encountered a bonobo! They are very rare and endangered, so even many primate caretakers don't have experience with them. It's a personal little dream of mine to visit the Lola Ya Bonobo Sanctuary; that would be a privilege.

I've also never even seen a bonobo in person. Only a small handful of zoos house them.

Wow, if I had a nickel for every time The Ghoul Boys popped open a can of beer to lure out an entity, I’d have TWO nickels! Which isn’t a lot, but it’s weird that it happened twice.
