1:37 ITS COMING RIGHT AT US!!!

[tevvytevv]

why is there a baby bottle on board the station

[gmcglothern]

is the fresh egg the one unable to spin stably along its long axis?

[Zagexi]

@gmcglothern yes because it's filled with liquid.

[ApolloWasReal]

He should have pointed out the bubbles in the water bottles. They were critically important in allowing the water to slosh around and dissipate energy. If they weren't present, the conversion of the rotation to the axis with the greatest moment of inertia wouldn't have been nearly as rapid.

[zorb2000]

disagree with the book not spinning stabily 0:20, It's stable, its just rotating on two axis, much like how an asteroid tends to 'tumble'

[andzlou]

InerTIA! It will spin along its axIS! 

[goodwolf359]

dare them to spin a sphere of water just fast enough that it forms a disk

[Vei2aC]

i think the hard boild egg is the one that spinns on it's two point's better as it's more dense but the fresh egg (the egg he spinns first from 1:20mins) spinns more unstable as it's more of a viscous liquid in a fresh egg.

[ApolloWasReal]

@Vei2aC Right about which egg is which, but that's not the reason. The raw egg contents can jiggle around and dissipate energy, and that's crucial for causing the change in spin axis because it involves losing energy. An absolutely rigid object will spin smoothly about any axis because there's no mechanism to change it.

[ApolloWasReal]

Too bad the engineers designing Apollo didn't have these videos. On its way to and from the moon the Apollo spacecraft was spun slowly about its longitudinal axis for passive thermal control, but just like the liquid-filled cylinders here that spin around an axis with a small MOI wasn't stable. It was very hard to set up these PTC rolls, and they often had to be corrected when they began to cone.

[B19Dav3]

I presume from this you can acertain that bodies always want to rotate their longest and most stable axis?

[Level84]

@B19Dav3 not really, short or long axes could both be equally stable... it just depends on the distribution of mass on either side of the axes. The liquid filled objects and the objects rotated on random axes both rotated unstably because their axis of rotation didn't intersect the objects center of mass.

[ApolloWasReal]

@B19Dav3 The most stable axis for a non-rigid body like one filled with a viscous or bubbly fluid is the one with the greatest moment of inertia, and that's usually its shortest one. The axis across the water bottle is shorter than the longitudinal axis about which it initially spins. The book spins most stably around the short axis through the pages.

[thekingsora]

probably a huge question i wonder how it would look if i took a piss in zero gravity

[heromage46]

@thekingsora Well umm u dont go to the bathroom normally in space-.-

[MrRocketjon]

@lionsforlyons No, the moment of inertia has nothing to do with it. The liquid, as any other flexible thing, serves to change the kinetic energy of the whole system, dissipating it as heat. Since the lowest energy state , for the same angular momentum, of a spinning solid is spin about its largest MOI axis, that is the stable state. For a prolate body (pencil shaped body) that axis is a transverse axis, so spin about the long axis is unstable.

[MrRocketjon]

The earth of course has a lot of liquid but it is stable because it is oblate, that is, it is spinning about it's largest moment of inertia.

[MrRocketjon]

The long liquid filled tube is not stable. It's divergent time constant is just too long to have the nutation growth observed in the experiment time.

[Kittykatkiddo101]

the fresh egg spin off course becuase the yolk is swinging it

the bioled egg spins solidly becuase it is completly solid

[fragglesmackdotcom]

I want EGGS IN SPAAAAACE!

[ApolloWasReal]

Excellent demonstration of how spinning objects with internal energy dissipation (fluid filled containers) convert their spin to the body axis with the largest moment of inertia. But note how the overall angular momentum is still conserved; the spin axis remains pointed in the same direction in space.

[0rangeKush]

Both of the eggs had holes in them? WTF

[jtfunkymojo]

why do they have a baby bottle?

[sudoLinux666]

@jtfunkymojo It's a challenge to drink in space. So you need to pull, or 'suck' the liquid into your mouth to drink it. The baby bottle seems to have that requirement, and completely sealed pouches with sealed fitting straws work as well.

[jeryhen]

Our earth is hot liquid with a thin layer of crust, so eventually the same thing will happ-OMG! T_____T

[hcarvalhoalves]

They always spin around their centers of mass?

[TwitchandFirefly]

@hcarvalhoalves No, because there IS no mass in the center when its in anti-gravity.

[75niteowl]

@TwitchandFirefly There is always mass. Mass doesn't change, only weight does. You can do the egg experiment in your kitchen right now, you don't need microgravity for that.

[sudoLinux666]

@75niteowl Correct, inertial mass is always present, even if there isn't any gravitational mass.

[light24bulbs]

it cost thousands of dollars to lift that book into space. Astronauts need e-readers.

[Somethingproductable]

Wait...why did they bring a baby bottle on the shuttle?

[MrPneumonia]

@Somethingproductable Because in microgravity, cups or glasses don't work. To drink, they need somethink that would work in those conditions, in this case, the bottle.

[BellaDiL0]

I want that camera lens.

[tommy2ter]

the hard boiled egg is the one that the axis of rotation stays constant. The fresh one is the one that cannot have a constant axis of rotation due to the fluid encased in it is changing position therefore changing the centre axis of rotation

[hazzard77]

what's the point of these space-missions? is it just so that we have videos to watch?

[cyborg4r]

@hazzard77 The guy recorded this in his free time

[L0ver80y]

things filled with liquid will stay on their axis if you spun them with some sort of instrument instead of a hand, which to start with isn't stable at all, the liquid gains inertia with friction inside the bottle so when you release the bottle you can't interfere with the axis or the liquid will gain momentum in which the bottle is spinning, and the radical inertia of which it was released.

[computerfreaq17]

@L0ver80y But I honestly think that that would be impossible to make it stay on a certain axis indefinitely, since there may be some small, unnoticeable imperfections in the container, causing the liquid to have some kind of small drag. This is just a guess though...

[L0ver80y]

@computerfreaq17 Your completely right, you would have to build the container atom by atom so that there was no imperfections, even then there's friction with the smoothest materials, you'd have to have a magnetic field pushing on the liquid inside so it wouldn't touch the inside surface, even then I'm sure it would stop or become erratic.

[luigiman83]

I want to have sex in space!

[Arvak777]

We should have more science classes in space, just drinking water would blow our minds into warm pudding!

[Rikdakidd]

i wanna go to sleep in 0 gravity :O

[felix1qaz]

Why is there a baby bottle in space?

[225USAboy]

@felix1qaz it is a bottle used for transferring liquid to the astronaut's mouth.

without it the fluid would fly about the cabin.........

[meteodub]

Cool!

[mikeymike3232]

if you dont know which egg is hard boiled your an idiot, half the video has obects that wouldnt stay on its axis because of liquids...

[hitlermugabetashtwin]

Why would you boil an egg, and then keep it next fresh eggs?

[myskateboard16]

@hitlermugabetashtwin ... what?

and the hardboiled egg spins stably..

[hitlermugabetashtwin]

@myskateboard16 I was referring to his final statement.

What I mean is, why would people living in space (or anywhere) boil an egg, and then just put it back with the eggs that haven't been cooked? No one does that.

[zzzIdividedbyzerozzz]

@hitlermugabetashtwin Its just for the sake of the experiment :P

[otaklub]

and there they go our taxes LOLOL

[Welocy]

"It will change its axis of rotation and tumble and over and" wut?

[Zlazuja]

@Welocy tumble end over end

[fdssg]

@Welocy "End over end," noob.

[Welocy]

@fdssg Not a native English speaker

[fdssg]

@Welocy Ah okay.

[Welocy]

@fdssg But thanks anyway

[helpdonate1]

Imagine doing a 900 flip

[Meashisgod]

i need to go to space

[Halapartna]

his voice is badass

[dodgedart74]

so the core of earth isnt liquid?

[Zryuken]

Spheres do not tumble.

[procletnic]

@dodgedart74 Earth does not wobble much because the moons gravitational force is stabilising the spin.

[dodgedart74]

@procletnic what about all the other planets, or did you forget about them too?

[procletnic]

@dodgedart74 The other planets have their influence but it is rather weak compared to that of the Moon. Why do you think tides exsist? They are not formed thanks to the gravity of the other planets and are only dependant on the Moon. Ofcourse our planet is a very small part of a bigger gravitational system major players in which are Jupiter and the Sun.

[clearlydecember]

@procletnic and you point is......

[procletnic]

@clearlydecember my point is well defined if you follow the conversation

[fartpopartist]

Request of motion to observe two magnets diametrically opposed in a fixed, rotating aparatus.

[Lleanlleawrg]

The reason for the baby bottle, its probably better than opening a bottlecap and having liquid fly around and getting into everything.

[asdasdasdasdasdas98]

WTF baby bottles in space, wonder if they got a baby up there???

Im sure they would be interested to see if a baby would survive and grow normally!!!!!!!!!!!!

[siztem]

who brought the baby bottle, and why

[adlebadle1]

They don't leak...

[siztem]

sure it doesnt leak. a lot of things dont leak. but who needed a baby bottle

[bengt123]

Err, they use it to drink maybe.......?

[pitecman]

So do humans spinning along the long axis head to toe do not wobble because of the circulation of the fluid in our bodies. we are basically similar to the liquid in the bottle right?

[sougamo]

Liquids have no sences to see and understand how they spin,nor muscles to pull themselves around.All I'm saying is a human could change spining axis on will

[edward052191]

the egg that wiggled the most was NOT boiled.

[erjohnson227]

actually, the egg which spun along its long axis was the hard boiled egg egg, the other egg which began to tumble along its long axis was the fresh egg.

[anothershakey]

@edward052191 wow, you're so smart! :P

[AsiansOf94]

hey this video gives me an idea of making a turbine in space to produce electrictiy

[94valeRa01]

OMG I want be at 0 gravity ^^

[davidsong85]

the last one shown is fresh egg cuz liquids do that

[TSDFurReal]

Imagine how hard it would be to flip a coin.

"Heads or tails on who goes to sleep first?"

[peteyg1]

wouldn't be that hard, just clap it after it's spinned for a few minutes

[Agentoxedo07]

Holy-Terrorist:>*=*

[ingolifs]

does anybody think this guy sounds like a stereotypical nerd from the simpsons or something?

[tails2fan]

1:37 by giving them a spin *bink*

[SkyboxMonster]

now try a bouncy ball in micro gravity

[Paneatix]

hahaha

[aijii]

@hairyDingos lol

tub girl in space would be kinda funny

[diilanG]

@aijii it would be messy and somewhat traumatizing, but yeh, kinda funny

[sbpeeps007]

@hairyDingos long range jizz shot

[torolof]

@hairyDingos imagine cleaning later!

[YukiCupcake]

@hairyDingos yeah , careful so the cum doesn't goes for your face x]

[lizerdspherex]

@hairyDingos Until it gets everywhere like a snowglobe> >:L

[Fredy216B]

fresh eggs should change their axis of rotation due to the liquid inside, since hard boiled are close to solid, they will not change

[unclechicken]

Checklist for space ship.

1. Dont make a ship full of water.

2. Always take hard boiled eggs as food.

3. If you really, really want to make your ship full of water, make it really thin and long.

FFS, its like a $50bn playground up there...

[puretroubleman]

The people stay up on the ISS for long periods of time, they are going to experiment with basic stuff as well as advanced. lighten up.

[TheReaverOfDarkness]

sweet! you could cook some of the eggs for breakfast tomorrow, and put em right back with the other eggs.

[vanepico]

Don't flip pancakes!

[tomanyasses]

body in motion stays in motion until acted upon, well thats what i and they think butt if a worm is reading this im a scientist and i say this is true butt if your a worm you say your not a scientist cause scientist dont talk like that.

[DieAndBehold]

No, they'd say your not a scientist, tomanyasses, because worms have the inability to read.

[tomanyasses]

i bet your a cronic smart ass and worthless blabbing idiot arent you going for turd of the week on you tube low life

[teacherphysics]

Your an idiot sir, go back to stupid school ass head!

[DieAndBehold]

Why would I go to "Stupid school"

Are you a complete moron? Schools are for teaching. Such as how to use real grammar and punctuation.

You should learn them sometime.

[Scoo]

What, did Don sneak a baby on the mission?

[siztem]

thats what i'm saying

[grondin240]

If u listen with no sounds, the firsts objects are like in a poltergeist...

[supersimy]

Fresh one is the white one! Oh wait..

[xXpezcoolXx]

So ur in space? that's cool!....no-gravity is hard no? no physical movement

[watchnasatvcom]

So cool, just really neat stuff. Like being a kid, in space everything is new again.

[36016]

That's a good analogy.
