  • what if you took the liquid out from the balloon?

  • @jcyoshi It would still boil and turn back to a gas, just not in the balloon.

  • Lol i like how i just randomly think "what would happen if a balloon were to be frozen?" before going to sleep hahaha xD night :)

  • Nice vid. Liked.

  • awesome iam suscribing

  • Subscribed. Love these videos!

  • @JeffersonLab

    Thank you

  • Water is liquid at room temp. Nitrogen liquefies at -197.15°C. Helium liquefies at -272.65°C. The lower the atomic mass of the element or compound ( gas or liquid at room temp. ) the lower the temperature must be to liquidate it. Does this mean that Hydrogen must be extremely cold to liquidate or can't liquidate at all?

  • @superfrenchfrys Hydrogen does need to be cooled in order to change to a liquid, but not as much as liquid helium.

  • @superfrenchfrys That's an over simplification, it depends on the intra-molecular forces of the substance. Beryllium has an extremely high boiling point (5000 C) even though it's atomic mass is less then most constituents of air.

  • @fabjonjon you can light it on fire there is so oxygen it is displaced by the nitrogen

  • grade 9 science, hahahaha fun times.

  • no, hit 9 fast!

  • hit 6 fast

  • I'm wondering the relation to the air that we breathe and water that we drink to substaining life.

  • I saw a photo once that showed (whole) liquid air; it was blue. =^.^=

  • @VulpesFidelis Actually, liquid oxygen is blue. You don't get the blue color if you just condense air.

  • that is cool

  • Is it safe to drink the liquid air?

  • @taterskins Nope. It's far too cold.

  • @taterskins Is that a joke?

  • thats soo cool! subscribed

  • Lol thats liquid air ¿Wat?

  • light it on fire or mix gas then light it on fire

  • pretty interesting, thankyou!!!

  • isnt it liquid oxygen instead of air?

  • @okmankk Nope, it's liquid air. The balloon is filled with air (nitrogen, oxygen, argon, etc...) and that, for the most part, is what gets liquified inside the balloon (the argon is actually frozen, but still...).

  • Can you make a video like that then pop the ballon? I am subscribing now!

  • @MarkLatimerRussell You mean pop it while there is still liquid in it? We could, but it wouldn't do too much. It would be like cutting a hole in a plastic bag with some water in it. The liquefied air would just fall out and there wouldn't be much of a pop since there wouldn't be much air pressure. If you just want to see some balloons popping, take a look at our 'Instant Liquid Nitrogen Balloon Party' video.

  • Amazing, what would happen if you were to pop the balloon while the liquid air was still a liquid?

  • @1rich14 It would be a bit like a water balloon. The liquid would spill out, hit the table/floor and rapidly boil away.

  • @JeffersonLab amazing

  • @JeffersonLabs Why can you spill it on that table like that and it not mess it up or damage it?

  • @iShaneFan The table is made from wood and, in the grand scheme of things, wood is fairly dry. Structurally, it can take it. If the wood contained a lot of water, it would be a different story.

  • 100,000 people are thinking "YAYYYY BALLOON!!!"

  • It's cool, but your writing is beyond cheesy.

  • @PaintedGay Well, yeah. But, in our defense, if you consider our "Liquid Nitrogen Ice Cream" video to be the pilot, then this was our very first episode. I like to think that we've improved since then.

  • THATS SO NEAT!!!!

  • Also another question when particles slow down like water turns to ice it expands and fills up more so space so I am somewhat confused

  • @johnken0 Two different points. First, here we're going from a gas to a liquid. There's a huge change in volume when doing that. Second, you're talking about liquid water freezing. The proper comparison to what we're doing would be steam to liquid, where there is also a huge change in volume.

    But, yes, when liquid water freezes, it expands. It's one of the few things that does. It's an exception to the rule.

  • So you can use liquid nitrogen to store balloons and also what would happen if the liquid air would leak out?

  • @johnken0 If the liquid air were to leak out, then the balloon wouldn't re-inflate.

  • do you guys still make videos?

    

  • @crackuhbottle Yes. We just haven't had the chance lately due to other priorities.

  • you do know that you dont have to wear gloves.

  • @hardcoregamer941 And you don't have to wear a seatbelt, either. But, you are far better off if you do.

  • lol the guys so terrible at pretending he doesnt know anything

  • is buying liquid nitrogen for any common man is legal

  • @adityasahu96 Yes.

  • Is there an element or compound that is gaseous at room temperature, and has a freezing point that is higher than nitrogen's condensing point so if you bubbled it through the liquid nitrogen it would depositate (is that what it is called?..)?

  • @MrMontez11 Sure. Carbon dioxide comes to mind. Water vapor, too. Argon as well. The process of going from a gas to a solid is called deposition. Not sure what the proper usage is. 'Deposited' maybe?

  • @JeffersonLab I'm impressed that the latex in the balloon stays flexible and doesn't break due to the extreme cold

  • @wb5rue I think that part of what happens is that the warmer parts of the balloon are able to expand when needed. But, yes, it is a little surprising that the balloon doesn't end up shattering.

  • LN2... It's pretty cool.

    *Badum tish*

  • how do you get this liquid nitrogen?

  • @historybuff4 The literal answer to your question is "From the Test Lab liquid nitrogen fill station." But, you're probably asking where -you- can get liquid nitrogen. Check in the Yellow Pages under 'welding supply.' The places that supply gases to welders typically carry liquid nitrogen. Just be aware of the hazards liquid nitrogen presents, both in use and in transportation.

  • @180Trist No, I don't think so. At least, not normally.

  • What is the liquid air?

  • @itdoesntmatter30 It really is a mixture of liquid oxygen and liquid nitrogen. There's also a little frozen argon in there as well.

  • can you drink the liquid air?

  • @jameel969 Sure, in so much as you can drink any liquid. But, you can drink mercury or gasoline, too. And, just like trying to drink those liquids, trying to drink liquid air wouldn't be a great idea.

  • Where can I buy big airship balloons like that one?

  • @poopleton Apparently, from a place called Qualatex (qualatex.com). Unfortunately, there isn't anything on the bag that gives me much of a clue as to what you would order. No size or special description or anything. The numbers under the barcode are 71444 75460. The barcode box is also marked with a '50' and a '646Q', if that means anything.

  • Yes, it does! From what I have looked up, 646 is the size - 6" x 46" & Q is just the manufacturer (Qualatex). I've seen some on E-Bay, which I might bid on :-)

    Thankyou for the info :-)

  • @poopleton And I'm guessing that the '50' means that there are 50 of them in the bag...

  • i heard that if you touch liquid nitrogen bare handed, your hand freezes in under 1 second

  • @par0l It depends on how much you touch. If it's only a drop, it may freeze a small part of your hand, but it won't be able to freeze the entire thing. Place your hand in a container of liquid nitrogen and, yeah, it'll freeze it solid. It'll take longer than a second, though.

  • ware do you get liquid nitrogen

  • @2010myanna We get it by the truckload from a local supply company. You could get it from a place that sells gases to welders. If you do decide to get some, know that it can seriously hurt or kill you if you don't know what you're doing.

  • This was cool. I did not know this.

    When they jammed the balloon in liquid nitrogen, and some of it spills on the table, I taught some of it might spill on that guy sguatting behind the table. He would just lose all the bodyparts hit by liquid nitrogen, right?

  • @bary1234 Some of it did spill on the guy squatting behind the table. He wasn't hurt mainly because the amount of nitrogen that actually got on him was very small and what did get on him fell off almost immediately. It kind of like dipping an ice cube in the ocean and expecting the ocean to freeze over.

  • @JeffersonLab: Ok, thanks for the reply :) I tought that stuff is like liquid metal, really destructive to human tissue.

  • That's a great experiment! Awesome thorough explanation.

  • can you make a helium filled baloon freeze and then shatter on impact?

  • @MYEYESONECONOMY Not really. We don't have the equipment necessary to freeze helium.

  • @JeffersonLab i meant, because helium doesn't freeze (shrink) as fast,could you freeze the baloon around it so that it would shatter ?

  • @MYEYESONECONOMY Interesting idea, but it's still not really going to work that well. As you can see from the video, the balloon stays fairly pliable, even when it's cooled down to liquid nitrogen temperatures. It just doesn't become glass-like.

  • @JeffersonLab okay, thank you for the answer!

  • @JeffersonLab wow awsome stuff well done!!

  • that was actually really cool. Didn't expect that

  • I could do that for hours :D

  • @jeffhardy075 cool video man

  • would the same thing happen if it had helium in it?

  • @MrBugeyes1 Not exactly. The balloon would shrink a bit due to the lowered temperature, but it wouldn't get cold enough for the helium to change to a liquid. We're planning on doing a side-by-side comparison in a future video.

  • @JeffersonLab ok cool i'll be sure to watch that one. so how cold would it need to be for helium to change to a liquid?

  • @MrBugeyes1 About 4.22 Kelvin. The nitrogen is only 77 Kelvin, so we're still well above helium's boiling point.

  • cool video man

  • I watched this today in science, that's an awesome experiment!

  • Oxygen turns to liquid oxygen at a lower temperature then nitrogen does I though. So is the liquid inside the balloon the other gasses in air turning to a liquid?

  • @wowcolors Under standard pressure, nitrogen boils at 77 K and oxygen boils at 90 K. Boiling liquid nitrogen is colder than boiling liquid oxygen. The balloon is a mix of liquid nitrogen, liquid oxygen and frozen argon.

  • can u drink liquid N2?

  • @Almontmarine Can you physically drink it? Sure. You can drink any liquid that you like. Of course, it's not a great idea to drink any liquid you happen upon. Like gasoline, for instance. It's physically possible to drink it, it'll just kill you. Same sort of thing with liquid nitrogen. It's physically possible to drink it, it's just a horribly bad idea to do so.

  • @JeffersonLab

    ?!? Oh sorry, I mean to say is it toxic if you drink it? :)

  • @Almontmarine Nitrogen isn't toxic. After all, we breath and ingest it all the time (burps come from somewhere...). Although liquid nitrogen isn't toxic, it's still extremely dangerous to drink since it's extremely cold. It won't poison you, it'll just freeze and kill the tissue it comes into contact with.

  • this is pretty incredible!!! :) I thought the balloon was actually going to pop, but it just got compressed and filled with liquid air. How interesting!!

    great video, thanks for posting!!!! :)

  • this bored me

  • why not try the same thing with water balloons?

  • What would happen if you were to drink air? O.o

  • @Iceblue2005 You mean regular air? Well, if you 'drink' air, you end up burping. If the air doesn't come out that way, it has another option that it'll eventually use.

  • @Iceblue2005 Your stomach would freeze and you'd die

  • @Iceblue2005 ahahahhhahhaha omg i was just thinking of that loolz

  • @Iceblue2005 If air by you mean oxygen. Liquid oxygen is toxic. since it's pure Very reactive that's why in the air you have different gasses.

  • My mistake. Liquid oxygen has a higher boiling point than liquid nitrogen. I was looking at melting points. How silly of me.

  • Seems like a physics fail. Liquid oxygen is much colder than liquid nitrogen. So the liquid in the balloon can only be liquid nitrogen, not both liquid nitrogen and liquid oxygen.

    Now if the balloon was put in liquid oxygen (very flammable and expensive), then both gases would condense. But this is not the case.

  • kool

  • cool vid

  • wow never thought there was such thing as liquid air prety awesome 2 know

  • @nubserver yeah air can turn into a liquid if it gets very cold and shrinks or if its under pressure

  • 0:30 good thing he was wearing protection!

  • @chubbsfan111 Actually, yes. I got a fair amount on me on a few of the takes. Goggles are good! - Steve

  • cooooooooooool

  • what is liquid air?? can u drink it? if your pop it will the liquid air evaporate instantly? can u make oir into a solid if cold enough?

  • @caleb12naruto Liquid air is just air that's been cooled to the point where it has become a liquid. In our balloon, we mainly had a mix of liquid nitrogen and liquid oxygen. You can drink it if you don't mind freezing your esophagus. You can also drink gasoline if you choose to. Just because you can do something doesn't mean that it's a great idea to do it. If the balloon were to pop, the liquid air would boil away fairly quickly. It would be gone within a second if it landed...

  • @caleb12naruto ...on the rug that's on the floor in the room. If it lands on a nice, smooth surface like a wooden table, it'll last longer since it ends up shielding itself on a layer of gas, something known as the Leidenfrost effect. Even with that, it'll only stay for 30 seconds or so. And, yes, you can make it into a solid if you get it cold enough.

  • Can u put an ipod in liquid nitrogen please?

  • @MaidenFan24568 If we come across one that no one wants anymore, we will.

  • @JeffersonLab

    Cool, now im subbing

  • @MaidenFan24568 that would be awesome!!!!!!

  • @MaidenFan24568 WOOOOO MAIDEN ROCKS!

  • im subbing! ive seen 3 vids and they are all amazing

  • @14ramosr Thanks!

  • that was so cool!!

  • Thats really cool, I am going to subscribe now!

  • Thanks!

  • nice

  • I'm a fan now :P

  • if that exploded in the flask, there would be liquid nitrogen all over.

  • Liquid Nitrogen + Liquid Ethanol = best Halloween Fog.

  • but where to find liquid n2

  • For us... not hard at all. We get supplied with about 6,000 gallons a day. For you... check the Yellow Pages under 'welding' or 'welding supply' for companies that supply gases to welders. Know the safety hazards before you use it.

  • pikajes96, air aint vacum

  • Air,and liquid,IT MAKES NO SENCE,AND NOONE CARES!!!!!!!

  • What would happen if an alkali metal was put in a container of liquid nitrogen?

  • I'm fairly sure you just get a cold alkali metal. The bond in a nitrogen molecule is a triple bond. It's not easily broken.

  • umm can i run liquid nitrogen in a air conditioner coil and put i fan infornt and have much cooler air ? sorry for spelling

  • Sort of. Running liquid nitrogen through an air conditioner coil and putting a fan in front of it would definitely give you cold air. The problem is that the air conditioner's compressor won't be able to recompress the nitrogen back into liquid form. You wouldn't have a closed system, so you would have to keep supplying the system with fresh liquid nitrogen.

  • i see

  • but if you did that wouldnt you get that disease that divers get for breathing nitrogen to much?

  • Nitrogen narcosis? I think you only get that when you breathe air under pressure. Plus, if the liquid nitrogen is in a coil, it isn't mixing directly with the air. Blowing air past the coil would just cool the air.

  • i dont really remember but cool thanks

  • can you mack Liquid Nitrogen in to ice

  • It depends on what you mean by ice. If you mean what you get when you freeze water, no, since nitrogen (N2) isn't the same thing as water (H2O). If you mean 'ice' as in a solid, yes, we can freeze liquid nitrogen to create nitrogen ice. That's actually on our list of things to do!

  • @Xavier56100 The atmosphere is 70% nitrogen already

  • The heck with acting. I liked the video I think they are cool.

  • Wow cool :d did this i my class :)

  • so in theory if you drank the liquid air would you breathe?

  • There are two problems with this theory. First, the liquid air is 321 degrees below zero F, so drinking it would just freeze whatever tissue it came into contact with. Second, drinking it puts it in your stomach, not your lungs. It would make you burp, but that's about it.

  • true but say it wasnt that cold and you breathed in that would it work?

  • Okay, so if you somehow had warm liquid air and you inhaled it... it might work. I'm not a biologist so I can't really say for certain, but the cells in the lungs would still be 'seeing' a normal nitrogen/oxygen mix. Whether or not the actual oxygen/carbon dioxide exchange mechanism would still work is beyond me.

  • It would expand when changing back to a gas. Your stomach would probably pop.

  • The gas would most likely escape before your stomach popped. Not to be tacky, but it's going to come out one end or the other.

  • I liked this. I did not know you could do such a thing and have learned something from this vid.

  • I love you PV=nRT

  • ideal gas law?

  • Awesome project! I love how you make science fun. High school chemistry would have been a lot more engaging had my teachers tried this. Thanks for posting! :o)

  • You say this vid is meant for kids? I'm 28 and I enjoyed it.

    But then I have a mental age of 10 probably....

  • the acting is horrible. don´t do it, just do it cold logical style :D

  • Mr. Spock finds some liquid nitrogen and a balloon?

  • you guys need to stop pretending that you don't know what your doing or what going to happen.

    your not making videos for children are you?

  • Actually, yes, we are. Our intended audience is middle school students - 5th and 6th grade mainly. Whether or not that's what we get is another matter. I don't trust YouTube's demographic information, so who really knows. So, if the science seems really basic or overly simplified, no insult is intended. We just don't want to confuse the person who may be seeing this kind of thing for the first time. Hopefully, it's still entertaining even if you know this stuff. If not, we're sorry!

  • its not that it seems basic or over simplifed it is and that's fine.

    I'm just saying the videos would be of better quality if you didn't do any acting and just approached it as normal science teachers would.

  • Let's just say we're still working on perfecting our craft. This video, I believe, was the third one we filmed if you don't count the liquid nitrogen ice cream one. We were still getting the feel of filming. We still are, actually. Hopefully, we've improved over time.

  • I disagree. One of the problems with science experimentation videos in general is that they are often poorly made and boring. Very tweed. The tweeness takes away from the subject content - when I was in school we would just laugh at the clothing and lecturing style of such science videos with their poor presentation skills obscuring the content.

    This video is brilliant, love the style, even the slightly sub-par acting kind of has a comedic value of its own that highlights the content.

    Love it.

  • Just 'slightly sub-par' acting?

    Thanks!

    I think that's the best review our 'acting' has ever received!

    Seriously, though, thanks for the comment.

  • My apologies, I meant no offence!

    Indeed, I wouldn't change a thing about the video. It's pretty good and you both present the material an an intriguing way!

  • No apologies are needed and no offense was taken. Believe me, neither one of us has delusions over our acting skills.

  • sorcery!

  • BURN THE WITCH!

  • The duck method is better.

  • nice vid,that was really cool!

  • Hahaha, I would love to be a chemist for a living.

  • corny acting

  • Please, don't confuse what we are doing with acting. It's an insult to real actors. ;-)
