This is how blue eyes get their colour

Blue eyes don’t get their colour from pigment – it’s actually way more fascinating than that.

  • by Fiona MacDonald

“Your eyes aren’t blue (or green) because they contain pigmented cells. As Paul Van Slembrouck writes for Medium, their colour is actually structural, and it involves some pretty interesting physics. As he explains, the coloured part of your eye is called the iris, and it’s made up of two layers – the epithelium at the back and the stroma at the front.

The epithelium is only two cells thick and contains black-brown pigments – the dark specks that some people have in their eye is, in fact, the epithelium peaking through. The stroma, in contrast, is made up of colourless collagen fibres. Sometimes the stroma contains a dark pigment called melanin, and sometimes it contains excess collagen deposits. And, fascinatingly, it’s these two factors that control your eye colour.

Brown eyes, for example, contain a high concentration of melanin in their stroma, which absorbs most of the light entering the eye regardless of collagen deposits, giving them their dark colour.

Green eyes don’t have much melanin in them, but they also have no collagen deposits. This means that while some of the light entering them is absorbed by the pigment, the particles in the stroma also scatter light as a result of something called the Tyndall effect, which creates a blue hue (it’s similar to Rayleigh scattering which makes the sky look blue). Combined with the brown melanin, this results in the eyes appearing green” (read more).

Skull Armchair by French designer Harold Sangouard, aka Harrow “Built For Comfort And World Domination”

  • exterior structure: polyester resin and fiberglass
  • internal frame: steel
  • cover black cotton velvet
  • black gloss finish
  • each chair is numbered
  • 103lb
  • L 47.6” x W 40” x H 40”

Kevin, no. The velvet will show ALL the cat hair.

Well, that was a disorienting photoset.

I figured it was something small enough to hold in your hand, and then it started turning around and I was like “…wait. Wait that’s a chair. Not a hand-held thing.”

(“Unless it’s a really tiny chair, I suppose, but it wouldn’t seem right to go through all the trouble of making a chair like that and not being able to sit in it.”)

What do you do if you’re a harmless, gentle snake and someone scares the pants off you? If you’re an eastern hog-nose (Heterodon platirhinos), you bluff. And when you bluff, you bluff like crazy. You flare your neck like a cobra (spoiler alert: there are no cobras in the Northeast). If that fails, you roll over dramatically and play dead. If someone rights you, you make sure to roll back over so you look properly dead. You also release every bodily fluid you have on hand. Nearby humans may feel compelled to say “What a clever snake!” just because they can tell you’re really trying.

The Edison : Steampunk Nigth Club in Los Angeles CA

This was my second home in LA T_T (ok so I only went for birthdays, whenever I took people downtown and on Thursdays when my kid was with her dad cause they had $.35 cocktails for happy hour XD)

Once I took a friend for Happy Hour and the fairy that serves the absinthe (she rolls around a cart with tiny bottles of absinthe cocktails) came out and saw me and said “I’ll be out in a few, ok?” and went back to load the cart. my friend was like, “Um… how often to you come here??”

i am legit jealous

Batman: You know Clark, there’s one reason why I’ve felt relatively comfortable working with you, despite the fact that you could probably punch the moon into dust.

Superman: Why would I even do that?

Batman: It’s because you were rai–

Superman: Why would ANYONE do that?

Batman: –sed human, even though you–

Superman: There is literally no possible benefit for anybody if the moon were to be punched into dust

Superman: What, does everyone think I’ll just wake up one morning, “Hey, looks like today’s a good day to eat breakfast, go for a walk, and oh, obliterate the moon”

Superman: “Probably punch the moon into dust,” unbelievable

it aint real fanfiction unless their tongues battled for dominance

#i’ve liked and reblogged this before, #but i suddenly thought, #what if their tongues don’t WANT to battle for dominance?, #what if you get two people with, #like, #really submissive tongues, #would their tongues just like, #lie there waiting to be dominated, #what a weird mental image (cosmic-llin)
