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 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.
@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...).
@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.
@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.
@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.
@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.
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?
@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.
@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.
@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.
@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 :-)
@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.
@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.
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.
@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.
@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.
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.
@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.
@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!!
@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.
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.
@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.
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.
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.
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.
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!
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.
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.
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)
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!
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.

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.

so in theory if you drank the liquid air would you breathe?
ramshxc22 2 years ago
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?
ramshxc22 2 years ago
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.

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....

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!
JeffersonLab 2 years ago
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!
deconverts 2 years ago
No apologies are needed and no offense was taken. Believe me, neither one of us has delusions over our acting skills.

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