- NospmisRemoh, on 10/12/2007, -2/+6I personally can't stand all of the morons in the world the simply sleep the night away and come in early in the morning and digg a story that was posted while they were sleeping. Any inteligent person would be sure and filter through all the stories they missed over night to make sure they don't digg a dupe. Stupid lazy Americans.
And, don't even get me started on people who are so lazy they miss reading Digg for days or even WEEKS. Then they, and hundreds of others like them, wander in here and digg a story that was already posted in their absence. I mean the nerve of hundreds of people to digg a story up to the front page that I and dozens of others already dugg at 3:00 am Monday.
Thank you sir for your overnight diligence, as a tribute to you I have dugg this story to ensure it makes it to the RSS feeds of more people so they can read your insightfull comments about the fact that this story has already been posted while they were sleeping.
[/rant][/sarcasm] - phpCypher, on 10/12/2007, -0/+2water is highly mass-magnetic. the only reason it is acting like a 'glue' at the nano scale is because there are fewer water molecules for it to stick to thus, this magnetism is greater between two opposing (non-water) bodies when water is present.
Stick any metal plate onto a wet glass table surface. It will be hard to peel off, but slides very easily across the table surface.
I think this effect is intuitively displayed as well in surface tension/cohesion as well as in capillary action. - wrinkles, on 10/12/2007, -0/+2In bulk water (3-D), the hydrogen bonds are pulling on any particular molecule from all directions. Therefore the net force on any molecule of water cancels out.
On the surface of water (2-D), the net force on the surface molecules tends to pull them inward (therefore water forms drops and has surface tension). Which is why some things float on the surface of water, but will sink when pushed into the bulk. (No, I'm not referring to items just soaking up water and sinking).
What these scientists appear to be doing is measuring the 1-D properties of water. The probe is so small that essentially tiny "fingers" of water attach to the probe, acting like tentacles. - NospmisRemoh, on 10/12/2007, -0/+2Or, for the rest of us who skipped biology class, the way the coaster stickes to the bottom of your pint glass on a humid day.
- megaton, on 10/12/2007, -2/+4Yep, that's right. PhysOrg is just covering it for kicks...
Quit modding that guy up, folks. - tallgreen, on 10/12/2007, -0/+2HCL is an ionic solution. It connot exist without water. If you evaporate HCL, the hydrogen and chlorine gas evaporates also.
- shawgo, on 10/12/2007, -0/+1I take it these "scientists" are out of the loop?
- Ssandman, on 10/12/2007, -0/+1yea, whenever someone says " its a DUPE!" it pisses me off because the person assumes EVERYONE reads every article that passes through this site. some of us DO have lives and cant sit in front of the computer for hours at a tmie ruining other people's posts because they are "dupes".
Dont trash smoeone else's post, i tried to post a story once, and i tel you its dam hard without finding at elast 5 other stories that arent the same. - x713, on 10/12/2007, -1/+2This is not so old news especially for many people. They just tested this out recently by not freezing... whatever, here for the ones who don't read which obviously don't, "Jinesh and Frenken explain that the reason for these lube problems is that, on the nanoscale, water ceases to be wet and slippery and instead becomes solid and sticky.........This finding contrasts previous studies, which suggested that water acts like a lubricant down to the nanoscale. "
- cleverboy, on 10/12/2007, -0/+1It's intrinsically silly to have conversation threads about how much the story being submitted doesn't "deserve" to be promoted or popular. A-roo? I thought the mechanisms were in place to "digg" stories you like, OR mark stories as "dupes" or "lame". Shouldn't that be all that's needed?
--As if stories somehow need an negative-advertisement crew inside its thread. Just avoid the thread in the first place, and let people think for themselves. If anything, instead of calling "dupe", people should just link to the "similar" story or "duplicate" link and move on. Eh. It could be the first time someone else saw the story. Big deal. - Verisimilitude, on 10/12/2007, -2/+3OMG!!! Really?!? You mean someone finally "proved" my grandfather's breathing on a spoon to make it stick theory !!!???!!
This is Science? No, not really.
no digg, no news, no cookie - mackfish, on 10/12/2007, -0/+0Different forces at work here..
Those are macroscopic forces like "Surface Tension" - the same reason why you see a miniscus (a bowing of the liquid) at the surface of water in a glass. Whereas the atomic level forces are entirely different (and i don't understand them!) - Rmplstltskn, on 10/12/2007, -3/+3These scientists could have saved a lot of money if they woulda just rolled a blunt.
- phatvolvo, on 10/12/2007, -0/+0digg you anargeek for obscure reference of a great book.
- iWorks, on 10/12/2007, -2/+2everyone knows that frozen water molecules on your tentacles causes shrinkage and they'll call you "tiny finger, tiny finger..." and you'll end up crying and going home all sad and will probably never graduate from MIT so don't even think about it.
- buckyboy314, on 10/12/2007, -0/+0Actually, it doesn't evaporate as hydrogen AND chlorine gas; it evaporates as hydrogen chloride gas. The acid hydrogen chloride is just this gas dissolved in water.
- Rickler, on 10/12/2007, -11/+10DUPE
*for those of use who have checked every article in the past 8 hours. - abstraxion, on 10/12/2007, -5/+3I thought this was pretty basic knowledge, like the cohesion/adhesion we learned about in biology class?
- patm1987, on 10/12/2007, -6/+3is HCl a liquid? (HCl == Hydrochloric Acid || Hydrogen Chloride)
i don't think the paper test will hold true there. - ub3rgeek, on 10/12/2007, -10/+7um not quite a dupe, although they are very similar, this is about how that the water acts like a glue. not that its possible to freeze water at room temprature.
- Anargeek77, on 10/12/2007, -4/+1Sounds like Cat's Cradle.............ICE NINE
- KMcG, on 10/12/2007, -7/+1I saw this in action this past week when a wet advertisement on my windshield got glued to it when it dried. I still have some residue on the windshield...They are so lucky they didn't have a phone number on that thing or they would have had an earful from me.
- arduenn, on 10/12/2007, -10/+2Heck, ANY liquid will act like glue. Just dip a piece of paper in it and stick it to your forehead.
- guttertrash, on 10/12/2007, -10/+2dupe dupe dupe dupe dupe dupe dupe. dupe iddy dupe dupe dupe.
- Flankk, on 10/12/2007, -10/+1Spam spam spam spam,
spam spam spam spam.
Lovely spam! - Rosewood, on 10/12/2007, -16/+5Not only is it a dupe, this is highschool science.
