[clintzoto]

This is great. Thanks for the post!

[Brotagonist]

Wow thats so awesome that even trolls cant hit the dislike button :)

[xGuest10101]

you cant even imagine or dream about the experiments they are doing on the space center!

[bulinger96]

lol. I'm a nerd.

[Anusdhka]

How can they make the water stay in mid air? are they on space?

[MrLoko435]

@Anusdhka their in space

[bryce995]

now put a air bubble in the little droplet....

..

[Avalon400]

WOW! Thanks ! This is great science !

[sciencoking]

If I was on the ISS, I'd do this kind of stuff all day.

[joedawson007]

anyone know how theyre holding the water in the air like that?

[usmcboi13]

@joedawson007 LOL its called being in space -- they are doing these expirements in the space station!

[DarxLotus]

you know u have to take your pant completely ooff to sit on a toilet backwards....

[barkerd1]

Awesome!!!

[fedaykindc]

its a bubble within a bubble within a bubble.....

[thorsworld2000]

should try it with soap water ... I'd love to see if it strengthens the outer shell to test a mock universe with different colors and such ... I can see it in my head ... that would be awesome

ha, at 4;11 he pops the bubble, it seems so similar and yet so different from what we get here on earth, these videos are fascinating.

I don't think he'll ever see a vagina bubble

[somnolent49]

@davidchenard, have you ever gone swimming? Ever dive down as deep as you can, and feel that tremendous increase in pressure? That's the compression added by only 10-20 feet of water above you. The pressure that feels "normal" to you is from the atmosphere, it's a column of air miles and miles in height, and it contributes less pressure than that little amount of water does. Now imagine instead of water, having rock and earth over your head, and instead of 20 feet, 3,958 miles.

[davidchenard]

@somnolent49 I have imagined that. At 20 feet down, I have a huge mass below me pulling the weight of that 20 feet down on me. At 3,958 miles down, what do I have pulling anything down on me? In what direction is the mass of the World and from what direction will I feel gravity pulling? How can pressure be generated at a place where gravity pulls from all directions?

[Towedwart]

@davidchenard Untested theories aren't theories at all. Those are hypotheses. Gravity is a relatively weak force. You can momentarily beat Earth's gravity simply by jumping. Yet this same force is what collapses planets into solid balls (not hollow balls). Gravity comes from the center of an object. The further from the center of an object, the weaker the pull of gravity (and exponentially so). Earth's gravitational pull is much stronger at its center than its surface.

[davidchenard]

@Towedwart A hypothesis states a predicted outcome to a study. I'm not predicting the result of an experiment, and learning what is at the a planet's core can not be tested. Gravity draws objects at or near the surface of a celestial body toward it's center. Where did you learn that gravity comes from the center or that it is strongest there? Is that a fact or what? If at the center and equally surrounded by matter (the source of gravity) in all directions, you would in theory be weightless.

[Towedwart]

@davidchenard I learned about gravity thanks to Isaac Newton and his gravitational theory. His equation explicitly states that the gravity of an object weakens the further from the center of that object you are. The point I was trying to make was that you can't be weightless at the center of the earth because there's a bunch of solid iron there. There is no empty space to float around weightlessly. I'd suggest reading up on physics, astronomy, cosmology, and probably some geology.

[zdxl01]

I THOUGHT ONLY I COULD GO THREE LAYERS DEEP

[hittingbees]

yo dawg i herd you like bubbles

[asdf2345234]

Clearly they need to add a .5" diameter bubble of vodka, observe the oscillations and then add jello mix.

[jamontoastst]

inception bubble!

[Raxterdax]

Osmosis.

[Sentinel3D]

Cool stuff. Exactly what I thought would happen, though I hadn't anticipated the whole mass transfer and surface tension as a propellant thing

[slowplaysrs]

@Sentinel3D so basically you knew what the title told you but you thought nothing of the science involved.

[Sentinel3D]

@slowplaysrs No. it makes perfect sense, but it doesn't enter your mind until you see it. I'm not ashamed to admit that. Perhaps if I were challenged to anticipate what would happen, I might come up with it. I don't know.

[DelusiveDragon]

Mass is a form of energy, so when the object loses mass it gains momentum keeping its energy the same. As energy can not be created or destroyed. Hmm I think :P

[davidchenard]

@DelusiveDragon Mass is not a measurable form of energy. It is a measurable characteristic or aspect of matter. On the other hand, it is argued that matter is a form of energy. Though matter contains energy which can be released by energy, I do not see support for the argument that mass, an aspect of matter, is energy.

[jakoparg]

couldnt take my eyes off

:P

[davidchenard]

So why does the Earth have to have a solid core and not be hollow?

[grendelee]

@davidchenard gravity

[slowplaysrs]

@davidchenard becuase gravity is a force which pulls inward. It doesn't necessarily have to force to compact the mass at the core any more so it just sits there as one big ass hot pressurized place that cant be squished further unless, say, the moon was to crash to earth and the gravity from the two masses would increase.

[davidchenard]

@slowplaysrs That doesn't make sense to me. Is that air bubble under pressure? Unlikely. From the center of a planet, gravity would have to pull outward in all directions toward the surrounding mass with nothing to pull inward creating the pressure you are referring to. Air is lighter than water, yet you can see the water does not crash into the center forcing the air bubble out. The center of gravity is in the center of the water layer. Where would oil go if it was added to the water?

[davidchenard]

@kylezangar I suspect the center point of a planet must have little or no matter and be under little to no pressure where and a physical object would be weightless if placed there. I also suspect the center of gravity must surround the core in a layer below the surface possibly 1/4 of the distance to the core. This would allow for a planet to be hollow and prevent it from being solid. Why do you claim the Earth has has a liquid core?

[Towedwart]

@davidchenard Do you know anything about gravity? Or planets? Or science?

[davidchenard]

@Towedwart No. I only know what science is. As for gravity or planets, I only have questions and untested theories. That is all our science books have in regards to the same. Presenting theories as facts in text books does not make them so.

[nuclearbox2]

Yo dawg...

[airsearescue]

is this how the sun creates solar flares ? energy transfer in a similar way in the core of the sun

[marstrenght]

how to make this?

[MrMontugar]

@marstrenght step1: go to space

step 2: make a water bubble

step 3: use a syringe to inject air

[marstrenght]

@MrMontugar thx ill go to space!

[suiciders10000]

wow...... this is highly fascinating.

[LittleFox1976]

This one just made me smile. Love you mircrogravity stuff.

[kionay]

"...a sphere of air inside a sphere of water"

now i'm no scientist, but isn't that called, oh idk, a bubble?

-.-

[XANDERXXZ]

he has a scary voice.

[Cachicochip]

OSMOS :D

[Knowwon249]

@Cachicochip Exactly dude I was playing that earlier today!

[fartpopartist]

They could inject a fart bubble mixed with oxygen and see if they can ignite it with a laser beam.

[infernomunky]

now imagine all matter, spinning and rolling... at thousands of degrees... and cooling and colliding, and freezing and melting back in...

[avida13]

it has to be because of the surface of the bubble that comes in contact with the ``wal`` of the outer bubble then the forces that creat that bounce reaction can be measured to give info for the action that really hapens any mathematic online for the type??

[russellreal]

#1 when a mass transfer from the water outside of the air bubble and the inner water bubbles.. it looks like there is a LOT of energy involved and it is like an explosion of sorts.. I can so see the government making a bomb outta this.. I mean.. its WATER its renewable the cheapest bomb ever imo :) the only thing they need to do is create a vacuum inside a LARGE bomb shell.. fill it with water and then insert air into the middle drain the excess water and drop it.. the drop will keep it moving.

[russellreal]

continued:

then when it hits the ground.. thats a stop.. 30 seconds later the water bubble in the middle of the air bubble will lose force and then transfer energy and BOOM lol

[OldSchoolSkill]

To find required energy transfer (momentum) of the "mass exchange" shown here,

Multiply water's coefficient of surface tension

(0.073 N/m) x

Surface area of droplet (assuming droplet is roughly spherical despite perturbations)

4 pi r ^2

Assuming thermal exchange is negligible, should = potential energy of droplet.

PS: I like Hans' suggestion; see what happens when they freeze those bubbles. Should be easy. It's cold up there!

THAT would be a COOL experiment! ;-)

[Splortched]

Amazing.

[siztem]

AWESOME!!

[moe354sa]

Hey I'm a glass artist and this is fascinating

[marybob321]

tehy should put and ant in side!

[McCreamyBanana]

Mmmmm.... Very interesting.

[HansTheAtheist]

Have they ever tried to freeze them?

[karabinjr]

@HansTheAtheist I get bubbles in my ice cubes all the time, Thousands of scientific experiments in every glass of scotch I would be happy to get rid of

[PatronSaint210]

So your making a water bubble, with an air bubble inside, with a water bubble in that, and an air bubble within that? O_o confusing...

[PatronSaint210]

Lol that would suck if this pissed off the bubble and it inhaled everything around it like a growing black hole. I'd call it the water hole. xD

[ross350tube]

can you imagine

a biosphere made of water.....

with land inside

could be done.

easy ,cheap and soon

[sargo]

Dem meteors would like to meet with said biosphere and wreck its shit once it gets into orbit.

[speesy]

This is great!

You sould film this with a 2k FPS camera or even more for slow motion examination of these material transfers - Time Warp - like (DiscoveryChannel)

Two thumbs up!

[Tigers828]

Wait, I have a hypthesis; try to bear with me.

Okay, if the very inner spheres of water are "sliding" around the sides of the inner core of air, shouldn't that resulting momentum cause the core sphere of air to turn in the opposite direction around the sides of the outer water sphere?

Just throwing it out there. I have a very limited knowledge on this subject, it just seems like natural instict to me for the spheres to act this way. Am I right?

[chobertt]

Tigers828, your hypothesis can be resolved in a simple way: mass. Water has a density of 1 g/cm3(cubic), whereas air has a mass of 1.2g/L

Water is literally pushing down (evenly) on every cm of area of the bubble trying to compress it. Therefore the bubble will remain at the centre at all times, no matter what.

On the other hand, if you start sucking water out the outer sphere with a syringe, you could get to the point where the water can no longer hold the air in it and pop.

Clear? :-)

[020jeffs]

no dude, chobert's answer is irrelevant, the reason the "core sphere of air" isnt effected by the spinning of the water spheres, is because the coefficient of friction between water and air, is near zero. this means, the spinning water spheres have no effect on the air sphere, because there is no friction, its like trying to undo a bottle cap when ur hands are covered in loob.....lol

hope that helps

[mattphub]

Amazing! I would love to see this with studio quality lighting.

[jbear0000]

I want to go to space just to do this type of stuff.

[Choice777]

i wonder if there's a "no touching" sing next to the exibit :D

[arkor7]

cool

[andreirocks1992]

gotta go.. i lost my jaw somewhere around here..

[arsonin]

wait...so if there is no gravity...air in water no longer floats up and disperses into the air around...it simple stays in suspend animation in water?

[mirabilis]

where's up? :)

[arsonin]

im just wondering if air needs gravity pulling agianst it to rise?

and if it does...why?

[mirabilis]

yes it does, because in space water and air has the same weight, i.e. no weight.

[arsonin]

o...that actualy made sense. thanks ;)

[020jeffs]

weight is irrelevant, they might have no weight but they have masses in space, and these are relevant to each other in space, when water and air react with one and other

[mirabilis]

the question was why the air bubble didn't "rise". :P

[jockersshadow]

because, although water is denser than air, there is no gravity (or at least not a significant amount of it) to pull the water down, which is what happens: the water gets pushed down being denser, and the air is pushed up by the water to take up the space; in microgravity, though, there is no "down", per se, so the only thing that keeps the air from bursting out of the bubble, is the surface tension of the water.

[020jeffs]

air doesnt need gravity to rise,

air doesnt rise.

only hot air rises, cos it is lighter than the surrounding air, it is lighter cos the particles are "ecited" and there are less of them per unit area.

this is the same reason air rises in water, as water is more dense than air, there are more mols of it per unit area , gravity pulls on the water, more than the air, (per unit area) and so the water sinks in the air.

[arsonin]

thanks

[bluebell101]

wow

[its329571]

That seriously rules!

[Allorga]

Guys this is a sphere of water with au bubble in it, it doesnt have anything to do tiht eiither volcanes or Lightning Oo

You can learn things about surfacetension.

[butabenjai]

could this help explain how volcanoes are created through the different magma layers under the earths crust?

[naternatedowg]

its tectonic plates moving

[beakill]

these water sphere and water film experiments should explain alot about how the earths atmosphere works,the mass transfer could suggest how lighting forms,but in a different way due to different gravity,the explosive effect that appears outside the air bubble is similar to the explosive effect above a lighting bolt.

wild theory i know!..lol

thanx for posting,great stuff!

[watchnasatvcom]

Is picking his jaw up off the floor. o.O

[ToonSpirit]

Fantastic!
