OMFG cock* sucking forum  [pigtail] ised software of anal rape.
Wrote a lengthy explaination. Two lengthish rants about how it keeps telling me I submitted it twice and then deleting my post text

*Not my fault if the forum doesn't censor obvious words.

I guess it's all about what you define as space then.

OBEY!!!

Actually space is just a few degrees kelvin above absolute zero. There are still trace atoms, eh. And don't forget about photons.

The 'space' question here is not really in-space, we're talking about the behaviour of water + gas in null gravity, which can be either in space, or a room in space.

@Cookie: Only applies under a certain volume threshold. We're talking about a man-sized water blob. Don't forget that cohesive forces DON'T increase proportionally.

I wasn't asking about a man sized water blob. Amblin asked that.

I was asking about how it would behave in space in a straw. YOU PEOPLE DON'T  [pigtail] ING READ.

After that happens a few times, you'll learn to highlight all of your text and copy it before hitting "post."

Only anime shows I've felt any interest in over the years are Pokemon (original TV series) and various hentai.
so clearly jgrp is a goddamn anime connoisseur. his opinion might as well be law here.

Best Admin: jrgp, he's like the forum mom and a pet dog rolled into one.

No they don't. Also willing to bet that none of them knows the answer to your question, so they start asking fscking stupid questions like ' omg water freez in space lololol!111one!'

There seems to be no articles on your particular question, but,

From http://liftoff.msfc.nasa.gov/Shuttle/USML2/science/DPM.html:

Quote from: Arvid Croonquist, NASA Jet Propulsion Laboratory
Almost everyone is familiar with the three basic states of matter: solids, liquids, and gases. What sets these three states apart is the amount of attraction between similar atoms and molecules. In solids. these forces are so strong that materials will retain their basic shapes even under pressure. In liquids, the attractive forces, known as van der Waals forces, are strong enough to cause liquids to pool and form a boundary, called an interface with other fluids such as air. Yet the attraction is weak enough to allow liquids to flow when an external force, such as gravity, is applied.

In gasses, the attractive forces are so small that there is almost no interaction between the molecules. Because they will flow, or change shape, if an outside force is applied, liquids and gasses are known as fluids. The basic goal of fluid physicists is to understand how fluids flow under the influences of external forces, how particles and gas bubbles suspended in fluids interact with solid boundaries, and how fluids change phase, either to form solids or to change from one fluid state to another.

...In microgravity, the effects of gravity are nearly eliminated, making it the nearly ideal place to study fundamental fluid physics. In the absence of gravity very large drops can be formed because surface tension is now the dominant force affecting a liquid drop.

Considering this, the interaction between the air and water would probably be the same as in normal gravity. While the gas will attempt to spread out faster, the van der Waals forces would take over and prevent gas from dissolving [quickly] into the water. Since there's no change to the amount of matter, really there shouldn't be a very noticeable difference...

Just my speculation though.

Actually I just wanted to toss that into the ring for you people to consider. I don't care either way about this debate. Please learn to keep your idiotic opinion to yourself. Thank you for the trivial waste of time.

Ah, yes, and "wut color is j00 wallet" is not a trivial waste of time?

Yes because its quite clear in my first post I put the "What color is your wallet" thread  in such high regard that no one should attempt to create another. No one topic can compare to its glory.

The cohesive force is quite strong between individual water molecules though, in space if gravity isn't really acting on it, swimming in it shouldn't cause it to break up.  Having you there as an extra surface for it to cling to probably would help it stay together even better.

Strong? NASA uses sound waves in ZG to deform and and separate SMALL droplets, where the van der Waals forces is proportionally greater... as volume increases, the cohesive forces decrease relatively, so, uh...
