I was going to just leave this in the tags but no, I've seen too many people misunderstand this and it's very simple and easy to explain so I don't know why anyone who shares this fun fact doesn't use this analogy.

so if you took a few leaves and threw them into a blender and pulverize them to as fine a paste that you could they would still be green. this is because chlorophyll has a green PIGMENT in it. now I can't speak to the base color of blue jay feathers so we're just going to talk about blue macaws for this example. If you went and put a Blue macaw feather in a blender and pulverized it to the finest powder that you could you would get black powder. this is because blue macaw feathers have black pigment in them, but they reflect blue light because of a microscopic bubble texture on the surface.

to explain it further, have you ever seen one of those little rainbow hologram things? like how they'll put a holographic Crystal or sparkle pattern on like a Pokemon card?

yeah that motherfucker, if you tried to scrape the top layer of this card off to get the hologram "pigment", you wouldn't get bubkis. in fact if you scrape the top of this card very lightly, the yellow part would still stay yellow because it's yellow because it is PIGMENTED, but the hologram where you scratch it will stop being holographic. now it will still have the pigment underneath it because that is pigmented but the rainbow effect comes from a TEXTURE on the top.

you could even put these kind of holograms on chocolate, are you following? it's a texture!

it's the same reason that bubbles are rainbow colored despite being too thin to see pigment in them.

IT'S A TEXTUREEEEEEE!!!

blue pigment will always be blue, you can crush up a Rose and use the Rose goop to color something else the color of that Rose! leaves, bones, clay, rocks!! that's pigment! disturbing its structure will not change the color because its a PIGMENT!!!

but a blue macaw? a pigeon's neck? a raven's feathers? and a blue jay apparently? that's a texture.

"yeah that's how color works" NO!! bubbles are clear!!! they just happen to have a broad spectrum iridescent TEXTURE, and some bird feathers have a short spectrum of iridescence.

I love that he apparently got the job because he looked so pathetic that children truly believed he would be unable to solve puzzles created by a cartoon dog without their assistance.

kids really said “i can fix him”

the average person's understanding of the "squirrel" could stand expansion. most people think of grey squirrels and red squirrels. urge them to think a little harder and they might come up with chipmunks and flying squirrels, while asking "i mean, do those really count?"

prepare yourselves.

first up, red squirrels and grey squirrels (classic):

chipmunks (nightcore ass animal):

african pygmy squirrel (the smallest Squirrels):

thirteen-lined ground squirrel (fancier than you):

prairie dog (insanely intelligent and social):

marmots/groundhogs (the Biggest squirrels):

image

flying squirrels (how does she do it):

image

Indian Giant Squirrel (And why he ourple😂):

there are 200+ species of squirrel out there their family is one of, if not the most diverse of the rodents

I know people on tumblr looove stories of underwater cave diving, but I haven't seen anyone talk about nitrogen narcosis aka "raptures of the deep"

basically when you want to get your advanced scuba certification (allowing you to go more than 60 feet deep) you have to undergo a very specific test: your instructor takes you down past the 60+ foot threshold, and she brings a little underwater white board with her.

she writes a very basic math problem on that board. 6 + 15. she shows it to you, and you have to solve it.

if you can solve it, you're good. that is the hardest part of the test.

because here's what happens: there is a subset of people, and we have no real idea why this happens only to them, who lose their minds at depth. they're not dying, they're not running out of oxygen, they just completely lose their sense of identity when deep in the sea.

a woman on a dive my instructor led once vanished during the course of the excursion. they were diving near this dropoff point, beyond which the depth exceeded 60 feet and he'd told them not to go down that way. the instructor made his way over to look for her and found a guy sitting at the edge of the dropoff (an underwater cliff situation) just staring down into the dark. the guy is okay, but he's at the threshold, spacing out, and mentally difficult to reach. they try to communicate, and finally the guy just points down into the dark, knowing he can't go down there, but he saw the woman go.

instructor is deep water certified and he goes down. he shines his light into the dark, down onto the seafloor which is at 90 feet below the surface. he sees the woman, her arms locked to her sides, moving like a fish, swimming furiously in circles in the pitch black.

she is hard to catch but he stops her and checks her remaining oxygen: she is almost out, on account of swimming a marathon for absolutely no reason. he is able to drag her back up, get her to a stable depth to decompress, and bring her to the surface safely.

when their masks are off and he finally asks her what happened, and why was she swimming like that, she says she fully, 100% believed she was a mermaid, had always been a mermaid, and something was hunting her in the dark 👍

a couple of clarifying notes from a PADI advanced open water diver:

  • nitrogen narcosis happens to absolutely everyone, the only difference between individuals is the depth at which it can start affecting them. just like with intoxicants, your natural susceptibility matters, but also things like stress level, fatigue etc. (but unlike with intoxicants, you can't develop a resistance to the effect.)
  • it will always happen to you if you go below certain depth while breathing either unaltered air or nitrox. (18m/60ft is the safe limit for the first level of PADI diving certification, 30m/100ft is the limit for advanced diving, and generally around that second depth is where you could start experiencing noticeable narcosis.)
  • the severity of nitrogen narcosis progresses with depth, you're not going to go from fully cognizant to psychotic. BUT, it's very hard to notice that you're being affected by it, because unlike with alcohol you're not getting any physical hints at your condition, your mind is just getting quietly impaired. a frequent symptom is no longer being able to understand where up and down is, and swimming deeper instead of toward the surface.
  • nitrogen narcosis is one of the reasons you never dive alone, you always dive with a buddy, and why it's vitally important to periodically sync with your partner. it's on you to notice that your diving buddy is behaving strangely and to get them safely to a shallower depth. even if you're diving with a group, you must have a buddy, and you are responsible for each other.
  • and it absolutely cannot be overstated how dangerous nitrogen narcosis can be, and why discipline is the most important attribute of a scuba diver. sure, in most cases you'll realize what is happening, you will go up a few meters and regain your bearings, and laugh it off after the dive -- but you can easily find at least one recording on youtube of a group losing a diver, literally losing them, watching them swim into the depths never to come back, because nobody realized they were affected by the narcosis before they were at a depth where the person filming could not go after them safely.
