Kaye Effect
This awesome display of fluid mechanics in action was first noticed in 1963 by Kaye, and is thusly named after him.

FP Edit: This is shampoo! If you want to try it yourself, you have the technology! Bonus fun fact: if done with a clear liquid, it can behave like fiber optic cable with internal reflection!

Neat

PleaseMrLewisIsMyFatherImDoctorLewis
As a fluid mechanics engineer, fluid mechanics is freakin' crazy.
daveeeeeeed
Okaye
jsmithy2334
How do you even discover something like this
sarahlyzzibeth
Thanks, Kaye. Really cleared that one up.
AkevoTheBard
Every man has experienced this when trying to pee in the morning
cheesyweasel
Kinda like popping a zit, right? ...guys?
decorativemooseknuckle
Same thing happens to me in the morning with a bladder full of Guinness from a long night of drinking.
madunderscorescience
It's like a zit.
Epiphronic
Well thank god every kiss doesn't begin with Kaye

When given enough mass, fluid gains sentience and attempts to communicate with the nearest living being.
Sticklebrickk
My best guess is the liquid is at such a viscosity that it acts as a chain. When it piles up, the weight of it pushes down a little dip.
Sticklebrickk
Afterwards, this little dip is used as a bowl, with the weight of the fluid still forcing down on the bowl, it acts as a chain again, shoots

neat
HEYimSQUANCHINinHERE
Dats some crazy squanch
spaceymonkey
Yeah, I can squanch to that!

Kept reading as "Kanye effect." Kinda drunk. So... makes sense.
aselleus
In my head i always pronounce Kanye as Kane so i was doubly confused

O-kaye
TacoBoozeDay
see this is what happens when i pee but my mom never believes me
Hactick
Your mom has a different name for this.

AMPLIFIEDFootsteps5IntenseMusic
Could have made up something fun... Kaye = the Earth spins at a retrogressive state and the spiders worshippers salute the sunshine, but no
itsavacado
I swiped to this...then a bladder medication commercial came on in the background. Psssss.
Ulthirm
Do we know what causes it now? What materials does it occur in? Is it temperature specific, does it require a shape? Important stuff man
flamingflamingo
You can watch the video for an explanation. It's caused by the fluid's viscosity.
Ulthirm
And the point isn't that I can't Google it. I could easily but provide people with information otherwise
vDorothyv
Shampoo? Bullshit, I know pancake batter when I see it. You just don't want to share
LowEarthOrbit
Fine, you got me... =P
chittyb
For a second, I thought this was someone popping something. I am unsure how I feel about this. I'll give the upvote, but I may take it back.
LowEarthOrbit
I must direct you to my post's refund policy. "No returns without a receipt" Did you keep yours? If not, I can only offer in-post credit.
isthisalsotaken
I read that as the "Kanye Effect"
TheShiphoo
Another one
tipsbandana
same
kissmyash
I did as well
WarlordPipsqueak
"I can offer no explanation for this behaviour"
IAmNotASkeleton
So did Kanye.
siler7
Well, this fluid is dope and it does dope shit.
lovemesumfemdom
Shit I did too and I didn't even realize this would be odd until I read you
LowEarthOrbit
This fluid would have to be 1000's of times more self-absorbed for it to be named as such.
bigcj101
I spit out a little of my milk
Zreen
Xathraphor
Was it viscous enough to display the Kaye Effect or self-absorbed enough to display the Kanye Effect?
ThatSirPooptoyou
Best guess would be a temporary increase in density where the gel is being applied, leading it to shoot back out, especially with 1/2
flamingflamingo
Just because Kaye didn't understand it in the 60s doesn't mean it's not understood now. The video explains it. You're not wrong.
YouCapturedMe
I think it has to do with a changing rhyology. Like, the shear stress applied onto the liquid causes the liquid to thin out from a normal
YouCapturedMe
Thicker state. So, the liquid falling is thicker than the surrounding thin liquid and the falling liquid will push the thin liquid instead
YouCapturedMe
Of piling up as it normally would. But that is just my theory. Think how ketchup only flows when a force is applied to it.
Perovskite
Rheology*
YouCapturedMe
Thanks. I spell that wrong all the time. You think I'd learn by now.
dagg3r
None newtonian fluid falling from a height will act as a solid when hitting a surface, the force is distributed on the surface so the /1
dagg3r
/2 point of impact solidify and deflect off the subsequent layers and in turn you get a funneling affect which shoots the liquid upwards
dagg3r
Funnily enough in not sure if im completely correct but hopefully 4 years of an applied physics degree and 3 years of a phd in QMC studies.
dagg3r
Helped
thegricemiceter
not quite, this is to do with fluids that lose viscosity when a sheer force is applied. like shampoo thins out in your hands
ThatSirPooptoyou
Something this viscous, the pool under the dripping forms a parabolic shape and the drips ride along it, shooting it back up.. But who knows
GuyNamedSean
We understand the mechanics that cause it, the issue is that there are so many tiny variables that we can't predict the behaviour well.
AnonymouZero
you mean you need a mathematician?
desice
Three of them actually.
yoandhello
Four if they're drunk.
LowEarthOrbit
That is why mathematical fluid modeling is so damn difficult.
illogicalphallicy
"The difficulty in modeling fluid dynamics is too damn high!"
yoandhello
This is why we can't have realistic water in video games.
magicalmysterytour
Is that for real?... I genuinely did not know that
