Rotating Sphere of Water in Microgravity

[TickingClock2013]

Can everyone say hollow earth theory.

[zombie2093]

i wanna see mentos in diet coke

[qwex11]

Now I have to look for HRWH1's comment. -_-

[OldSchoolMetalScum]

Unbubleliveable!

[juliansalome]

Its not that bubbles go into the center of the spinning water along the axis of rotation... is that the water moves outwards (given its higher density) pushing the bubbles into the axis of rotation. You can verify this by watching the tea leafs also going outwards.

[quosmo1]

@juliansalome exactly. its simply a spherical centrifuge.

you could do it with tomato soup, some blood, or infact air bubbles with a little surfactant.

[Calcorperations]

Science used Water Gun!!!

[Loader2k]

Was that filmed on the 'vomit comet'? Too cool.

[Tonlondong]

i wanna play...



[TJDeadkid]

man i would trip balls in 0 gravity i could amuse myself for years playing with shit like this lololol

[goodwolf359]

spin it FASTER =D

[rdrgdz4]

i just came here cause it looks cool

[ItzBigidy]

How do u get in this room!

[TheThusComeOne]

...along with a few chunks of... Orange peel. Lol

[TechnoStickmen]

..now I have to somehow recreate that on my computer

[CommanderdMtllca]

@vytko16198

Accretion is the process of rotating particles combining in microgravity and that's what we see here. Accretion is also how galaxies, stars, and planets are born

[AGolstonT]

Seeing that the Earth is 3/4 water, what are the odds that the Earth behaves the same way? Is it possible the the center of the Earth is actually gas?

[ModestMagician]

@AGolstonT The surface of the earth is 3/4 covered with water. Earth itself is less than %1 water.

[JerkOnTheInternet]

@AGolstonT You can't possible be real.

[lzrd0113]

Would the bubbles in the center eventually combine to make it look like a donut made from water?

[PoopyThumb]

this proves that everything has a gravitational field no matter what the size is :)

[TheWhiteOwl23]

@PoopyThumb surface tension...

[PoopyThumb]

@TheWhiteOwl23 i stand corrected

[RJFlashCOM]

Physics are COOL!!!!!!

[borderraven]

What does ice look like as it melts in microgravity?

What if you add a bit of Ivory soap to the water?

[1isaacmusic]

I want some space tea :)

[MarcSylex]

This reminds me of a TED talk where a woman was presenting the theory for the existence of dark matter. I can't exactly what she said but it boiled down to the idea that dark matter encompasses galaxies. She added that stars in toward the center of our galaxy ( or any galaxy) has apparently the same rotational speed as the stars at the outer edges. Suggesting that these stars are somehow bounded together the invisible space we call dark matter.

[theoriginalmcsquare]

Anybody else feel tempted to grab the bubble?

[cacasarq]

the galaxy inside a bublle, nice.

[vytko1618]

very cool, how is it all done?

[Tjita1]

That's cool. Not extraordinary in any way, but cool.

[ninjabob52]

how'd they get it to spin?

[ApertureAce]

I want to drink the bubble of water.

[nisse112112]

@ApertureAce with a straw :D

[MucusFelidae]

@ApertureAce It will rotate in your stomach.

[FoxiAndFriends]

@ApertureAce Well now hold on there Ace, that's dangerous thinking.

[thekingsora]

kinda sounds like george bush

[TheFireHornLLC]

@thekingsora Came to see if anybody else thought so, too! It does sound like George Bush!

[bubbletanking]

Where is this taking place? ISS, plane, etc?

[bloodydiareah]

you guys eventually the bubbles will turn into a sphere :3 and thats how earth was made... lols :3

[duran66]

Stop creating your mini bubble worlds and tea worlds! You nerds are playing God!!!!

[benchy06]

@duran66 no they are not.

[duran66]

@benchy06 Playing God I say!!!

[benchy06]

@duran66 nope, we are playing God if we are toying with life. Like bringing back the dead. what they are doing here is just physics.

[CrappyMcJoe]

They look so delicious!!!! NOM NOM NOM



[whoyouuu]

the air bubbles look like a penis

[HAPPITYFUL]

gasp! water earth 0:49

[rusk1992]

i wonder if earth could have a bubble like that surrounded my magma??

[100Petrelis]

i like his voice:DD

[Evangeder]

how to make that sphere ;d

[ZuKahta]

@Evangeder go to space

[Evangeder]

@ZuKahta something else?

[ZuKahta]

@Evangeder you could try the center of the earth, but last time i tried that the continent started splitting

[boxol20]

cool :P

[Kadda67]

yummy



[DarxLotus]

this is how snowglobes are made

[Blue2Scripter]

i want to kick that thing really hard.

[grendelee]

That makes sense. I wonder if you spin a bubble the right way, will you have just a WHEEL of water, with a hollow center?

[kingkoopakong]

@grendelee that is retarded. look up how cohesion works.

[JOshAchorn]

HOW IS HE DOING THIS???????

[Policemanofficer]

I want to eat it.

Drink it.

Whatever.

[detroitrockcity22]

this might be the coolest thing i've ever seen

[gorgolyt]

i can think of easier ways to deduce that the density of the pills is the same

[serbwithblade]

Bored astronauts? I think so..

[zoldszemu998]

Gömbölyű víz, üres térrel a közepén és ízzel a felszínén. Ez ismerős.

[HRWH1]

i do know there are water bubbles in zero gravity, but i just dont seem to believe in this video. first thing that got my attention was how come u have a black background, why not white? or some other colour :s

[Pomme843]

@HRWH1 You don't believe in it? What, is this CGI animation?

The videographer probably chose a dark background so as to make the sphere more easily visible.

[TheMeansardine]

so the water wants to stick together evenly as a sphere and the gyro forces are trying to "disc" out the water by pulling the water towards the equator centrifugally. The water flows outward towards the equator and the air bubbles "gravitate" towards the center to try and even out the system of water to its most spherical shape? it seems like this creates a negative center and the positive buoyant bubbles will move to void the difference in pressure because all matter seeks rest.

[yurikolovsky]

so earth's center might be is less dense because of earth's rotation?

[Viking009]

@yurikolovsky I think not, as the sphere of water has a slightly lower gravity than the earth ;) But if it rotated much faster, then probably yes

[decathlete112]

@yurikolovsky The Earth and probably all planets out there spin soo much slower, if the rotation of that water globe were extrapolated to the size of I dunno the earth it would be drastically different, by the look of the speed of that water it would take about seven tenths of a second instead of 24 hours. Since it spins faster the forces are multiplied and it causes a narrow dispersion, if it were spinning much slower and put into a vacuum it would remind you alot more of Earth you know.

[DJLocoAl]

I wanna eat ALL of those bubbles.

[lordpoee]

It's like a tiny planet!

[lordpoee]

I wonder is this what the core of a Gas Giant like Jupiter look like?

[tatunkha]

tightly packed bubble core? Is that a new genre of music?

[Marathonmarch]

You could use the water as a delivery system for air in space

[Marathonmarch]

You could use the water as a delivery system for air in space if it wouldn't freeze

[Marathonmarch]

You could use the water as a delivery system for air in space lol

[Sentinel3D]

Makes sense that if you're rotating, the pressure is away from the axis. I'd like to see this experiment with it rotating on two axes.

[dembumboclot]

He begins all his vids with "here we have" the exact same way

[davidchenard]

We're told the Earth's crust is 3-18 miles thick and covers a flowing more flexible mantle that extends 1800 miles down. So we have a thin broken crust covering a molten layer of rock over 100 times as which belches gas through the crust constantly.

"Here we have a rotating sphere filled with bubbles and tea leaves, and as expected the bubbles go to the center and the.." Wait! "AS EXPECTED"? Why was this expected? if Earth's mantle is liquid and bubbly,why do we have a solid core?

[grendelee]

@davidchenard gravity

[davidchenard]

@grendelee Perhaps if gravity pushed, but it pulls. If you were in the center of the planet, you'd be surrounded by matter pulling you away from it. With gravity pulling you and everything near you away from the center in every direction, you would not remain in the center for long.

[grendelee]

@davidchenard and you think that would cause bubbles?

[9hello123]

@davidchenard Pressure. You have no knowledge of science whatsoever. Don't kid yourself.

[arlobrubaker]

what makes it spin?

[LostOliven]

Makes sense, since the denser materials push the lighter materials out of the way.

[o0SkateOrDie0o]

:49

Thats what earth is gonna look like soon

[op3852]

@o0SkateOrDie0o no, this means the 'Earth core is denser' theory could be wrong, no one knows what the center of the Earth is like, maybe it's Empty, lol.

[HJxJJ]

@o0SkateOrDie0o STFU

[bloodydiareah]

@o0SkateOrDie0o you mean thats what earth did lols

[1234REEB1234]

@o0SkateOrDie0o shut up hippy

[TurbulentG]

i wanna see it pop just pop the thing already 

[davidchenard]

@TurbulentG It can't pop. The air is not under pressure by the surrounding mass of water. There is only water tension.

[TurbulentG]

@davidchenard yeah i know it cant pop as such but cant you put your finger through so it splits into more little spheres?

[davidchenard]

@TurbulentG I'm sure you could, unless that water was really a living Blob monster that consumes everything it touches and grows bigger and bigger without end. Then probably not.

[NapalmDragonFly]

I wonder if this may give us clues to the shape of planet cores. What if the Earths core is an elongated molten iron like the bubble core (instead of perfectly round). This would open up some clues as to why the Earths magnetic field acts the way it does.

[davidchenard]

@NapalmDragonFly This is a huge clue, but don't assume Earth has a nickel iron core just because that is taught in science class. The reasons for believing that are hardly scientific. It seems more likely that planets are formed hollow from the start. the center of gravity would not be in the center of the planet.

[NapalmDragonFly]

@davidchenard

Nothing personal, but "Are you on Crack?"

Google "If We Had No Moon" and watch it.

[Slyeyes4403]

you must love tea cuss you say tea in like all of your videos

[15monarch]

omg is it mee or does it seem like the water is floting

[Suyamu]

@15monarch

yes, the water is floating - it's an experiment in zero gravity in space.

[Unclevertitle]

Wild! So, in lieu of strong gravity the denser than water tea leaves "sink" outward in the direction of the centrifugal force and the less dense than water bubbles "float" to the center in the opposite direction.

Hmm... a candle flame in microgravity goes out in a sphere, but if you were to spin the candle then the flame would "rise" to the center of rotation.

Now I want to see a circular candle with multiple wicks, light one wick, spin it in microgravity and watch it light the other wicks!

[RADIOACTIVEBUNY]

That is the coolest fucking shit I've ever seen.

[jaghatarkebab]

did someone just poop in the sphere?

[obrisky]

i REALLY want to slap that ball of water to see wat would happin

[dhstandard22]

Clicked on the video because I thought I saw a penis in a bubble....

[pointbky]

since all the air is compressed in the center could you poke a straw into it and breathe it?

[GodofCider]

@pointbky Well, all the bubbles of air are there anyways. You'd undoubtedly suck in some of the liquid as well, but there's no reason why you couldn't.

[sopimusician666]

how is the micro gravity achieved? are you in space or something? :D

[oldboystef]

@sopimusician666 It has to do with gyroscopic motion. Google 'weightless dumbbells' it should give you a good idea of how different weights can be achieved in this manner.

[bennemann]

@oldboystef uhh, googling that leads to an article stating that those dumbbells are fake and don't work. :/

[Nexstarcrazyness]

VERY INTERESTING! Reminds me of the Saturn hexagon. You know but saturn is all gas. I bet some interesting things might happen on a much smaller scale if we use different chemicals. Testing out gravitational distribution in a weightless environment can help us understand more about molecular structure in zero gravity.

[JozleMan]

Add some dirt, couple of seeds, and a little heat. Now you have created a miniature planet.

[Repudation]

Water bending!

[MacaAustralia]

The bubbles go to the center, that's a 50DKP minus!

[IHaveAnAnonymousName]

whered u get the antigravity?

[laidbackbazmac]

What device is used to make microgravity hold the water?

[346L3]

@laidbackbazmac I'd think the ISS? ;D

[CoolFire666]

One hell of a way to brew a cup of tea

[slipperywhenwet5]

Laziest job: zero gravity waitress "uh oh dont drop i- oh wait LAWLZORZSAUCE"

[zx6rtt]

space is....

COOOOLL 

[municsscareme]

its beautiful!

[georgeofthajungle]

it seems like our core should be less dense also

[soylentgreenb]

@georgeofthajungle Nonsense. Rocks don't float in water and vegetable oil doesn't sink.

So why is the Earth not like this blob of water? This water droplet is held toghether by surface tension, it is spinning very rapidly compared to the Earth and it is much too small to generate a significant gravitational potential.

[georgeofthajungle]

@soylentgreenb the earth is still spinning quite rapidly, thats why its more of an oval than a sphere. but like a fat person has to hold on tighter on a carousel, shouldnt the denser objects move towards the outside? the further away from the core the dense material gets, the less gravitational force acts upon them. i guess it just comes down to the speed in which the earth spins...

[NotKud]

It's a centrifuge without the equipment! Neato!!

[Kabukita]

looks like the astronauts were bored

[bstmanversusskeletor]

Along with a few chunks of orange peel.

[Rathause]

thirsty...

[anthwhite91]

Ahahahaha!

Here WE HAVE...

Here WE HAVE...

He puts emphasis on so many different words for no reason.

[wiz2111]

Throughout the whole video I wanted to see it pop

[ins0mniakds]

So then theoretically speaking, why couldn't there be moons or planets that contain millions of lifeforms protected inside the core of inhospitable or frozen surfaces and atmospheres? Hell for that matter (no pun intended) why couldn't there be NATURALLY occurring Dyson's Spheres in space. Hard to detect because what's left of the star (or it's twin) is encased inside the core of the system's debris collapsing back in on itself (around it's twin - maybe)!

[hayharut]

sooo... the denser the matter is it goes to the surface? and vice versa?

[99XiNUZ]

@hayharut as opposed to the water yes, works the same as a simple centrifugal force

[Viking009]

@hayharut Try to spin a bowl with marbles inside.. They will go to the edges due to centrifugal forces. Now when the water ball spins, it's the same, instead of that bubbles don't act like marbles, because they are denser. Here the water itself is the marbles. And as it travels to the edge, it pushes bubbles to the center.

[ginogrz]

looks more like an oblate spheroid to me. :p

[HlST0RY]

Gravity is a property of matter and 1 of 4 fundamental forces in the universe. The strong and weak nuclear forces are the strongest, then comes electro magnetism. Gravity is by far the weakest universal force. It's so weak in fact that a tiny magnet can pick up a paperclip even with the entire Earth pulling it down. Here's the real question though... WHY?! That's where the secrets of the universe lay. Higher dimentional energies. Maybe this a clue. Dark matter could be one such manifestation.

[Interleap]

Oh because the tea leafes are heavier makes sense :D

[aparkhurst1]

This video is totally "bubblecore"

[ATK101893]

Really? Can you explain?

[Envergure]

They should freeze it while it's spinning

[Interleap]

And bring it back to earth :P

[Envergure]

They could poke out the bubbles and make a necklace that can only be worn at he poles xD

[tigresssharplesl]

frozen spinning bubble would be awesome

[SpeedMjam]

why?

frozen material is boring it would be the same as when you use a spinning ball...

[Veerwhil]

Dude just shut up and have the Danube waltz play in the background or something

[UtubeFailure]

Nerd Partaaaaaaaaaaaaaay!

[Leeman7986]

Think about what this experiment shows about the formation of our own planet, maybe we need to rethink our own geologic model of the planet, since as you can see by this experiment the more dense material goes towards the outer edge of the sphere and inside the core is all the gas bubbles forming a cavity all the way through the sphere. Does this imply that the once discarded hollow earth theory may not be such a radical idea?

[yedrellow]

No it doesn't, google p and s waves and you'll understand why we're pretty sure that the earth is solid.

[Zyphet]

Gravity > Centripetal force

[redeyesthe20th]

yes but in the "trillion and trillions of years GRAVITY pulled the heavy stuff inward.

and earth doesn't spin that fast ; )

[Leeman7986]

I would like to see an experiment then, that has been scaled as much as possible to our own earth in these same laboratory conditions. Who has really gone to the core of our planet to see what is there? Here is a model of behavior that if applied on a much larger scale explains alot.  Notice how the sphere is flattened at the poles, much like our own planet as well.

[iorixs]

the earth doesnt spin at all

[tigresssharplesl]

no its flat and has little faries all over it. why dont you go look at an atlas or a globe or take a plane or even go into space and stay there for some years until you see that it is in fact spinning around its own axle. wich is why theres gravity in the first place moron

[ekocekoc1]

axis faggot

[andyduff]

We don't have gravity because the earth is spinning...

[ninjabob52]

@tigresssharplesl Axis rotation for a body of any shape, does not generate gravity. The two forces have little to do with each other.

[OnlyHardstyle]

its lookin cool but that voice is ffn annoyin meXD

[binary132]

I just meant he sounds ridiculously bored and stressed out, maybe they just need some space shorties all up in da hood. Lol

[binary132]

all of these videos of the ISS sound like they really need to get high.

[featheredmusic]

there's more to life then getting high, if tthey were high they'd be sitting at home on a couch not doing shit

[Xxero0]

And that's a stereotype that's not entirely true. Getting high helps you think. If he was gettin ghigh just to get high... ya, you might right. But if he was getting high for a reason, like helping him make sense of it, then no. He wouldnt be sitting on the couch doing nothing.

[blacksheep02]

Studies on THC's affect on dopamine systems would say otherwise.

[Xxero0]

It helps, bro. If I'm high and Im doing something mathematical, I always spned like 30 minutes going "Lets see how complicated I can make this and still get it right...." And end up with a whole page of work that has the same answer as 6(5+4).

And most studies on THC are bullshit, dude.

[blacksheep02]

Here's an equation for you:

bias stoner + shitty personal experience < scientific studies

[Xxero0]

And you just assume Im bias? And that I have shitty personal experience? And that those scientific studies are true? Dude, when they did tests on xtc they used meth. When the did tests of lsd they used lsa. When they did test on marijuana smoke they fuckin suffocated monkeys. And I'm not exactly a stoner, either. I only do pot occasionally, not everyday.

[featheredmusic]

@Xxero0 LOL you're saying that your brain is more cognitive when it's high?

I think not, that's we get high not to worry about all the bs we have to think about to survive. Okay go get high and build a rocketship lets see how well it will work

[Xxero0]

Conceptial thought is easier when you're high. And not everyone gets high to forget about the world. I do it to make it better, open my mind, and become creative. You seem fairly ignorant, not everyone is the same. Not everyone is lazy, and not everyone doesnt do shit. If it wasnt for psychedelics you might not even be on a computer right now.

[NoPetrol]

@Xxero0 What kind of analytical thought do you do when you're high, exactly?

[Xxero0]

I cant really explain anything about being high. Marijuana is something you have to have done it to know what I mean when I describe it. But the best answer I can give you is this:

When you're dreaming, dreams work in a similar fashion that thoughts occur while high. They're completely random, aspects of the subconscious that you have little control over. Ideas literally pour out of your mind. But it's different for everyone, perhaps it's the way it is for me because I have an artistic mind.

[NoPetrol]

@Xxero0 Well just like too much sleep can be a bad thing, the hallucinogenic state that marijuana puts you into is not conducive to analytical thought. Sure you may still be able to do things like play the guitar and paint, and I'm sure your guitar playing probably sounds better to you, but I would be surprised if you could do things that were mentally taxing, such as physics. That's why all the potheads major in communications and political science when they go to college to smoke more pot.

[shoopdawoop3]

@featheredmusic yeah your right its not like the govenor of california who was a insanely famous actor smoked weed he did by the way also so did obama

[featheredmusic]

@shoopdawoop3 You can smoke here and there, but i dated a pot head and yeah they don't do shit, it makes u relaxed, why would you want to solve problems, fuck it

just stating the obvious, i don't care if people smoke whatever, it's fun, but don't expect a pot head to build a rocket ship
