  • Lucas123, on 07/28/2008, -12/+247Science is cool.

    But it would have kinda sucked if he'd spilled that stuff on himself before getting it to the pool -- Terminator 2 flashbacks.
    • jacobu9, on 07/29/2008, -3/+59Sorry to destroy your GoldenEye/Terminator 2 fantasies, but pouring liquid nitrogen on your skin won't do anything, it will just boil away. The only way it will cause you to blister is if you continuously hold it against your skin, like if it gets stuck in your shoes or you cup it in your hand or something, otherwise it's like passing your hand through a candle flame, it doesn't do anything.
      • tomj88, on 07/29/2008, -1/+23yeah, if I remember correctly the temperature difference between your body and the liquid nitrogen is so great that it vaporises before it touches your hand or something to that effect so it doesn't blister your skin, but if you immerse say your hand in the stuff it doesn't get as much of a chance to vaporise so will cause damage to you.
      • laplie, on 07/29/2008, -1/+9actually, even if you put your hand in a bucket of it, you'll still be pretty ok. A layer of vapor will form between your hand and the liquid.

        One of the only real ways to injure yourself is to grab something (like a metal rod) that's been soaking in the nitrogen
      • burrgrinder, on 07/29/2008, -1/+19College physics class had us pour liquid nitrogen drops into our hands and stick our fingers into a bowl of it. Every person in the class did it, zero people were hurt. The extreme temperature difference keeps you safe, it never actually touches your skin. Really, the easiest way to hurt yourself with liquid nitrogen is to ingest it.
      • masterkenobi, on 07/29/2008, -3/+5Sure, tell that to Robert Patrick.
      • rmclaughlin, on 07/29/2008, -0/+10actually the leidenfrost effect (the vapor barrier thing) pretty much keeps you safe to ingest the stuff, as long as it isn't that much of it (and it doesn't touch your teeth).

        I had a high school physics teacher who would drink a bit of LN to get people excited about physics. All that would happen is that he would "burp" out a bunch of the gas.

        i couldn't find a video of him drinking the stuff (i had one on my old cell phone) but here is another one of his little "stunts"

        about 3:10

      • aterimperator, on 07/30/2008, -0/+2To be fair, it's not just the extreme temperature difference that keeps you safe, but also the very low specific heat of liquid nitrogen.
      • screamthenrun, on 07/30/2008, -0/+2@laplie...
        if he stuck his hand in the bowl he would be in trouble..
        but other than that.. pouring it over your hand will do nothing [i've done it before!]
    • alcavit, on 07/29/2008, -6/+35th grade all over...
    • clutchperformer, on 07/29/2008, -0/+8Leidenfrost effect.
    • MrCobaltBlue, on 07/29/2008, -34/+21***** you. two of my friends died jumping in a swimming pool that had liquid nitrogen thrown in it.
    • dotorg, on 07/29/2008, -0/+8As Jacobu9 said, it won't do anything. I've spilled it on myself before. Its freakin' cold, it stings like a mother but it flashes to gas and insulates your skin from the liquid part almost instantly.
      • squaredUP, on 07/29/2008, -2/+3So from that I derive that if you were to be in a cold enough environment the stuff wouldn't flash to gas and then instantly freeze dry your skin? And yes I'm aware you couldn't just be hanging out in a cold enough place long enough for this to feasibly happen; I'm just speculating here...
    • Urbalist, on 07/29/2008, -1/+8Ever pour ice9 into a pool?
    • smakusdod, on 07/29/2008, -3/+4Would have been extra extra cool if these guys weren't a bunch of dorks.
    • nbx909, on 07/29/2008, -0/+2yeah you only get a "chemical" burn if you keep it on your skin for long. The worst i've gotten is a few red spots that lasted about a day or two.
    • TheTaoOfBill, on 07/29/2008, -0/+2I'm not much of a chemistry person but does the chlorine in the pool have any effect on the nitrogen?
      • Qeveren, on 07/29/2008, -0/+2Not really. Nitrogen is a relatively inert substance.
      • unable, on 07/30/2008, -0/+2Actually, nitrogen is pretty reactive... it's the basis of most physiologically active chemicals. However, the presence of chlorine in the pool (most likely trichlor, a nitrogenous ring with alternating carbonyl and chloride groups) has no influence on the "reaction" that occurs: the state change is purely the result of the massive temperature difference
      • tech42er, on 08/02/2008, -0/+1@Qeveren
        Are you kidding? Nitrogen is an incredibly reactive element.
    • jasonh1234, on 07/30/2008, -2/+1Terminator 2? I think Jason X had the better liquid Nitrogen scene.
  • malexan, on 07/28/2008, -10/+291What about liquid nitrogen in a pool of Coke with Mentos thrown in for added fun!
    • schroeder, on 07/29/2008, -0/+60Don't forget the Pop Rocks!
      • ZER0JACK, on 07/29/2008, -3/+79FOOL, You'll kill us all!
      • nmnnotmyname, on 07/29/2008, -1/+9I think ZER0JACK is right....... Worth it, let's go!
      • griz, on 07/29/2008, -0/+4Why spend $6 Billion on the LHC when a Pool, Some Liquid Nitrogen, Mentos, Coke and Poprocks would do the trick.
    • pk7677, on 07/29/2008, -2/+2That would be a amazing combo.
    • RudeTurnip, on 07/29/2008, -4/+63Two friends, died, etc.
    • zhaojon, on 07/29/2008, -1/+5Umm... Diet Coke...
    • ungoliat, on 07/29/2008, -20/+3omg what a genius. oh and btw: "F*ck you. two of my friends dies pouring liquid Nitrogen into a pool with diet coke and mentos"
    • AFGUnit106, on 07/29/2008, -6/+2How about putting liquid nitrogen up my *****
    • hege27, on 07/29/2008, -2/+1that wold be cool

  • Adam420, on 07/28/2008, -38/+48Very old, and duh what else would happen...
  • kevbryant, on 07/28/2008, -6/+37Gremlins did it!
  • akpwnz, on 07/28/2008, -14/+5Would've loved to see his face melt off!
  • mnemy, on 07/28/2008, -13/+220Was I the only one cringing when that guy was walking around with a bowl of liquid nitrogen? If any of that spilled on him, I imagine it would be pretty unhealthy.
    • Sornos, on 07/29/2008, -3/+89So long as you don't immerse any part of your body for a long time you should be OK. I've seen a guy dip his fingers in. For a short time, it'll just boil around your fingers.
      • AshamedAmerican, on 07/29/2008, -10/+20Oh, is that all?
      • cyberfreak01, on 07/29/2008, -3/+65As you should know, gas is not a great conductor of heat, so when it boils at -320.42 °F it will actually create a little bit of a barrier around your finger from the liquid nitrogen. Still like mnemy said, can only do it for short periods of time. So yes, that's all
      • Spuy767, on 07/29/2008, -0/+4Yes, it's kind of like firewalking.
      • davidaod, on 07/29/2008, -16/+3320.42 Fahrenheit = 160.23 Centigrade, for those of you who live in the 21 century.
      • swiftsam, on 07/29/2008, -1/+9too fast on your smart ass comment

        -320.42 F = -195.78 C
      • nuand, on 07/29/2008, -1/+4actually it's -320.42 °F which converts to -195.78 °C
      • bitrot, on 07/29/2008, -1/+7And -320.42 °F = -195.79 °C for those of you who like relevant info.
      • Sornos, on 07/29/2008, -1/+12How about we use Kelvin, the correct way to measure temperature in chemistry? Nitrogen boils at 77.361 K.
      • cyberfreak01, on 07/31/2008, -2/+1because i'm not a chemist?
    • btschul, on 07/29/2008, -0/+23http://youtube.com/watch?v=R2f1ECjs9fA
    • Kalior, on 07/29/2008, -1/+2My chemistry teacher poured some out on his hand, it looked really cool, a pillar of smoke coming from his palm
    • origamistars, on 07/29/2008, -1/+9A friend of mine poured some into his mouth and spat it out as a gas. It won't hurt you... as long as you don't swallow it.
      • kraetos, on 07/29/2008, -0/+35That's what she said.
      • TecK415, on 07/29/2008, -0/+1I think I remember this being a story on digg a while ago. Some kid swallowed liquid nitrogen and somehow lived.
    • laplie, on 07/29/2008, -3/+5actually, a science professor died from doing that stunt. He put some in his mouth and it the gas expanded so quickly, his lungs pretty much exploded (in the sense that his avioli burst)
      • Namaha, on 07/29/2008, -0/+26[Citation needed]
      • alecks, on 07/29/2008, -0/+11I call BS... Your mouth would open before your lungs explode
      • captnkurt, on 07/29/2008, -0/+17Wait... someone had ravioli in his _lungs_?!

        1. a distilling apparatus, consisting of a vessel in which a liquid is heated and vaporized and a cooling device or coil for condensing the vapor.
        2. a distillery.

        Hmmm, good thing you found his still for him.
      • Gimpy1983, on 07/29/2008, -5/+3Good try smart guy...

        Still - With reference to action or condition; without change, interruption, or cessation; "it's still warm outside"; "will you still love me when we're old and grey?"

      Taking every opportunity possible to attack Americans just makes you look like a ***** retard. I mean as much as I wish we used the metric system I'm not going to whine about how everything sucks here, so why should we have to deal with people who don't live here whining about how much it sucks here?
      • kreejo, on 07/29/2008, -3/+6I agree with nmnnotmyname, I'm English and I've only been to America twice, I can't fairly comment on the country, and the only complaints I see are generated on the Internet, not exactly the most reliable community for opinions...The point is that England probably has just as many issues as the USA, as would almost any other country in the world, America is an easy target because of their huge global influence; they're always in the spotlight, and any mistakes are picked up on quickly and exacerbated beyond reason. It's not at all fair for them, but unfortunately it seems to be true.

        America ain't so bad, give them a break.
      • leladax, on 07/29/2008, -1/+1what do u expect from englishmen. every chance to lick american sweaty hairy balls.

      • skyroket, on 07/30/2008, -0/+2It's too bad you couldn't come up with something relevant to the discussion instead of going on about Englishmen ball-licking. Do 8-year-olds in Portugal like to have intense debates about sweaty ball sacks?

    • sysop073, on 07/29/2008, -0/+1If you mean like all youtube video narrators ever, then yes
  • recalcitrantid, on 07/29/2008, -3/+11How does a repeated digg dupe get 400 diggs, when it has 2 million views and was posted over 2 years ago? Not to be a negative nancy... but...buried for that.
    • ShakeWell, on 07/29/2008, -1/+3Because not everyone reads Digg everyday and remembers what has been posted and what hasn't. Most Diggers welcome a chance to see someone that others may or may not have seen a few times before.

      I swear. If given the choice of permanently eliminating either all dupe stories or all the people whining about them, I would get rid of the latter.
      • kh99, on 07/29/2008, -1/+1Well said. It's pretty ***** self-centered to think every story has to be something new and interestng to *you*. No one cares if you've seen it before. Just ***** bury it and ignore it. Do you have to comment on everything?
  • Onyxblaze, on 07/29/2008, -1/+19Just wondering... was that chick wearing her top?
  • shoguner, on 07/29/2008, -0/+4i was expecting the T1000 to rise up .
    • nmnnotmyname, on 07/29/2008, -0/+2Huh...
      I guess that makes more sense than who I expected to rise up... But It would've been really cool to see Rick Astley appear out of nowhere.

    the filmer = obvious douche.
  • 9bpm9, on 07/29/2008, -7/+3Boring.
  • Ageroth, on 07/29/2008, -5/+12As accurately as it was described, I am surprised none of you knew it by name.

  • nmnnotmyname, on 07/29/2008, -3/+1Is Japanese Youtube better than the US Youtube? Besides for Japanese stuff, I mean. Because it really seems to have more interesting *****. Or maybe we're just not interesting anymore :P
  • pault107, on 07/29/2008, -1/+50Fat girl jumps in - 'hey everyone, look at me, I'm just sooo crazy'
    • notwizt, on 07/29/2008, -0/+4Apparently, Penguicon (where it was filmed according to the youtube description) is an "Annual combined science fiction and fantasy convention with Linux and open source programming expo."

      Just wow.
      • LilRabbitFooFoo, on 08/11/2008, -0/+1So, the entire con's attendance was surrounding that pool then...

  • itsripitsrip, on 07/29/2008, -1/+6all the time.
  • Regulator980, on 07/29/2008, -1/+48For future reference if you decide to use liquid nitrogen:

    "You should *never* wear safety gloves when working with liquid nitrogen. Likewise, you should not wear any clothing (such as sleeves) which may get soaked in liquid nitrogen and then hold it against your skin.
    Liquid nitrogen is fairly harmless if it touches you or gets on your skin... the real harm is if your skin is submerged in it or covered in it for extended periods of time. So if you have no gloves and use the right handling utensils, then at most, you risk some splashes to the skin.
    If you have gloves on, however, you risk liquid nitrogen getting down into the glove and then freezing your fingers off.
    Just an asterisk... I'm not trained in this field or anything, however, I saw it on a Bill Nye episode where he was very firm with not wearing gloves while handling liquid nitrogen. =)"


    Quoted from a user (SIRBERUS) on Digg from a previous front page video.
    • monocyteLSU, on 07/29/2008, -0/+21I work in a research lab. Every week or two, I go and get about 5 Liters of liquid nitrogen and deliver it to my lab to be poured in a larger container. I wear Sub-zero gloves that go up to almost to my elbows as well as Safety Glasses. While gloves may not be needed during the transport of the liquid nitrogen, I can't see myself not using them while getting the Liq. Nitrogen or dispensing the liq. nitrogen. The metal hose used to get the Liquid nitrogen freezes over, so the gloves are most definitely needed there unless you want your hand frozen to the hose for a period of time. While dispensing the liquid nitrogen, I can understand that they might be a risk of pouring the liquid nitrogen into the glove, but the probability of that happening with the proper gloves and handling is slim. It serves mostly as a splash guard (even if the liquid nitrogen might be fairly harmless). Of course, this might just be what my lab does and we usually are very cautious when it comes to safety.
      • ericcire, on 07/29/2008, -2/+3Don't you mean you're cautious when it comes to danger?
      • terminal157, on 07/29/2008, -0/+1That makes sense in a professional situation where you have gloves especially designed for it and must touch items that are frozen by the nitrogen, but professionals are going to know that anyway. The tip was for amateurs, and it's a good one.
    • thembt, on 07/29/2008, -6/+2This is frozen CO2 (dry ice) not Nitrogen, http://en.wikipedia.org/wiki/Dry_ice you can watch many videos if you search for "dry ice", but giving a wrong title is a good way of gaining diggs
      • MaxPayne3476, on 07/29/2008, -1/+2? no no, it is liquid nitrogen... as dry ice is well... dry ice. Not dry water.
      • aterimperator, on 07/30/2008, -0/+1There's no reason to believe it's dry ice. Will dry ice do something similar? Yes. Does that mean it's not liquid nitrogen? No. While dry ice sublimates quickly and thus also creates a gas by simply coming into contact with water, liquid nitrogen boils quite quickly (it has a fairly low specific heat) and creates a gas by coming into contact with water. Thus, in this experiment there's no real difference, except for the fact that liquid nitrogen is easier to obtain than liquid CO2.
    • aterimperator, on 07/30/2008, -0/+1I think the primary problem with this advice is that with liquid nitrogen, there's always a container. The container I use is a metal one that has a thin vacuum as insulation to keep heat out. The handles are metal and get a bit cool. We use it to cool metal objects. But even if we used a glass beaker, there's still a container, and that container is still very cold.
