TheTruephantomking Good point!

huh?

How to make it 1000 times more interesting Replace liquid nitrogen with 1x liquid oxygen and 2x liquid hydrogen.

Liquid hydrogen will do the trick.

liqiud oxegen is 70 degs colder than liqiud nitrogen

Hermann Fegelein liquid -oxygen- hydrogen explodes // EDIT somehow oxygen and hydrogen got messed up in my head when i read comments above. weird

me too

me to

J.A.Ratt85 so pretty much "I like this dude, but he's really cool"

effects of temperature on equilibrium

Me to

Yep. And, if you didn't know that most fires need oxygen before now, you've learned something! That would make those eight minutes a good use of time!

I didn't learn anything new... Atleast I got to know that nothing exciting happens when you combine Nitrogen and fire.

Jefferson Lab "most" fires? Wait... there are fires that go without oxygen!?

morten325 Your first statement is contradicted by the second.

Narlie Titanium will burn in an atmosphere of pure nitrogen. Magnesium will burn in pure nitrogen, pure carbon dioxide and even under water.

legion2k that would be hilarious but kinda hard to pull off unless he pulled it out really fast so they wouldnt have enough time to identify it before it shattered

Zaa Lee just take a fake hand under the table, then freeze it.

legion2k I had a friend who pulled a prank like that on one of her profs at college. She put a piece of a hot dog into the finger of her lab glove, froze it, then tucked her finger into her palm and wore the glove (so the hot dog looked more or less like her finger), then smashed the "finger" and screamed. Her prof saw right through it but her classmates FREAKED. One of them fainted. ^_^

hehe... clever

I was just thinking that

ikr

+Thomas Heaven Chemistry is not about making big explosions

+Raymond Lei Of course chemistry may not be about making big explosions, but that thumbnail, description, and build up implied the video certainly WAS about making big explosions.

+frtard since nitrogen is an inert gas it is pretty obvious from the title that it won't explode. it will evaporate pretty quickly (also a kind of explosion).

+Jonathan Lässig how can nitrogen be an inert gas elements it is in grp no 15

Why not

Gottfried Leibniz *tries at someone elses home*

Boom

+Gottfried Leibniz Tries outside.

anywhere else except home

Victor Kyrg being a teacher is 40% teaching 60% story telling.

Agree 100%

Ikr accept for when he scared the crap out of those people 5:26

True

Drog2099 I wish

Are you Serious ? !!

Big Bang. The quark-gluon plasma cools, allowing nucleons to form. Clouds of hydrogen and helium gas collapse, forming the first stars. The largest stars explode, seeding the Universe with heavier elements. The sun forms. The earth forms. Life arises. Life evolves. Dinosaurs rule the planet. Dinosaurs are wiped out, allowing for the rise of mammals. Life evolves. Humans create language and art, master fire, build tools and learn agriculture. Civilization arises. Humans aren't completely occupied with survival, so there's time to discover how the world works. Chemistry, physics, biology, math and all of the other sciences develop. People learn how to liquefy nitrogen. RU-vid is invented. A video is made of a lit candle being placed in a container of liquid nitrogen. The video is uploaded. You click on a link. You arrive here. Elapsed time, about 13.798 billion years.

Jefferson Lab sweet....

Best answer ever

Although you missed the part about how when a mommy penguin and a daddy penguin love each other very much.....

Jefferson Lab I'm confused whether he wonders why he exists or wonders how he came across and watched this video, because I don't know the latter.

Hollywood Builded Mind ; D

***** Just because something is science doesn't mean it's not an explosion lol

The Curious Engineer People want a big boom and not knowledge, go figure...

Where i cant see them now

Oh you can see the dislikes, dude from the past? Well I cant. Thanks youtube.

+heroesandcons09 We are upset that nothing explodes!

+DrunkenShinobi Kind of a silly thing to be upset about. Imagine what the world would be like if nitrogen did explode. Walk across a carpet and touch a doorknob? *BOOM!!* You're gone. Light a candle for your birthday cake? *BOOM!!* You're gone. A springtime thunderstorm pops up? *BOOM!!* You're gone. You should be *happy* that nothing exploded, not upset.

thing is, im not upset but a tad bit underwhelmed. i mean, i already knew fire needs oxygen to work lol! not news to me, i just watched on intruiged and was a little bit disappointed by the end ya know. like, what's the point?

I like explosions.

Well go watch a Michael Bay movie or turn on your nearest TV.

lol But the explosions in movies are so unrealistic! How am I supposed to suspend disbelief when cars are exploding left and right. Seriously though, my comment was an attempt at a joke based off the character Frito from Idiocracy. I like this presentation and upvoted the video. ;)

ExperienceLOS7713 Not even Michael Bay can quench my thirst for explosions.

writer15131 The worst part is when the "good guys" have to go and save the day, disarming the nuclear device seconds before detonation. What a letdown. ;)

kauske Yeah, because that's what you want to do in a room full of kids...

Jefferson Lab the bar is higher when you put it on RU-vid. also aren't those college students

Shiggity Shwa The bar is set higher when it's put on RU-vid? Have you spent more than five minutes on RU-vid?? And, no, those aren't college students. They are in 8th grade. It's mentioned in passing in the video.

Jefferson Lab Ah it looks like a college chem lecture hall but ok and no i've not spent more than five minutes on youtube

Jefferson Lab They mean the bar is higher in a more negative way. Ie the expectation for something spectacular/dangerous/stupid/all of the above is greater, because it's youtube.

How so? If you were expecting it to explode, then you are lacking an understanding in how fire works and you used that time to fix that deficiency. That's a win for you. If you knew what was going to happen and you watched anyway.... Well, that was your choice.

Muahah even now years later you respond to old videos, never seen that before on a channel.

Did you expect a spectacular explosion? Nitrogen isn't even flammable.... lol

sneekyshot1 he`s dedicated

u thought it was gonna explode? LOL

Son of the Llama i think theyre 8th graders

No, @K Clardy is correct. This was a group of 8th graders. The older people you see are teachers and parents. This is a field trip and one does not send 230 8th graders out into the world without some sort of supervision.

OmGWtftRolOlOLolO!

Yeah something like that :OoOoOoOo

Corkoth55 only people that disliked

+Sion Additional videos are listed in the video description.

are you serious

@@official-obama are you serious

That's like mine but she's a girl so...

Loki Laufeyson And they say it's hard to get a job...

***** No one is telling you that. Why do you even think this is a college? Didn't you see the kids in the audience? It's even mentioned in the video that they are in 8th grade.

***** To be fair, they probably know it, they just don't know that they knew it. There's a difference between obtaining knowledge and applying that knowledge.

***** It's true though yes. Notice that when you enter the atmosphere which is hitting Oxygen leaving space you catch on fire? It's not just because of Friction. It's also because you need oxygen for fire.

This is not a computer game, where flames can freeze.

OpenGL4ever Of course I know that haha I wasn't intending on being realistic.

***** Not possible but if it was that would be so awesome!

Neutron Star Have you ever played a computer game or do you know, how they work?

OpenGL4ever Yes

+Cyrus Khalvati ikr

The nitrogen creates a layer of non oxygenated gas

Cyrus Khalvati exactly

I was suprised everyone thought something would happen, i mean its preeetty obvious fire needs a balanced mixed of heat, fuel and oxygen, thats like the basics

***** Actually, he stimulated their minds. He demonstrated one of the core principles of science which is to explore all potential possibilities. And he did it in an entertaining fashion.

+RanndomUndead because we wanted a explosion.

+Epcot lp (dawnqwerty) There has been a load pop. Not every chemical can blow up. All of the haters are dumb and know nothing about chemicals. Thumbs up to video, thumbs down to haters.

While that would result in a boom, it wouldn't be as big as you might be hoping for. Like with the liquid nitrogen, atmospheric oxygen would be purged from the inside of the container. The only 'boom' would come from a relatively thin layer near the top where enough oxygen has mixed in.

hmm.... So it doesn't work like stars? that's what their fuel is.

Spore Creature No, it's not nearly the same thing. The sun isn't burning like the candle burns. There's no chemical reaction with oxygen. The energy is a result of a *nuclear* reaction. Hydrogen is *fused* within the sun to produce helium, and the mass difference (4 individual protons are more massive than a helium nucleus) shows up as energy via the well known equation E = mc^2.

oh...... -_-

If only a fusion reaction was as simple as a small amount of heat and some liquid hydrogen.

As opposed to all the other minutes of your life that you do get back?

Go do something fun for eighy minutes and make up for it.

+PremierMilenkov A room full of people and, currently, about 7 million more on RU-vid apparently expected something different.

Jefferson Lab Which kinda makes me question the educational systems of most of the world :/

+PremierMilenkov I don't know if I'd go that far. I prefer to think that this is more of a knowledge vs. application of knowledge issue. I think (hope) that most people 'know' what will happen, they just don't realize that they know that they know. If not, then, yeah, your critique becomes much more valid.

Jefferson Lab I suppose that could be right. There are certain situations where you don't quite realise it's something you've dealt before in a different context.

+PremierMilenkov It's a room full of kids, not scientists. The whole point of classes is to *learn* what you don't already know. Besides, I think that a lot of them got caught up in the showmanship, either hoping or worried that it would make a big bang, lol.

im pretty sure thats the atmosphere, not air

Aron Gabor Same thing.

JayJay plass I think you're missing the point dingdingdingdiiiiing is making. The air/atmosphere is almost 80% and the world doesn't explode when a match is lit. Nitrogen clearly isn't a problem. So, why would 100% nitrogen do anything?

JayJay plass I think you'll find there are many more gases present in the atmosphere than just Nitrogen, Oxygen and Carbon Dioxide.

JayJay plass On that part, yes. You were correct.

No explosion. Like the alien at the end if the movie Contact

stefantrethan People were expecting something from an action movie, a lot of people think that science experiments are 90% explosions, loud sounds and bright colorful lights.

stefantrethan People want to see explosions and fire......You know, like the TITLE of the video leads you to expect.

Gregg Macey If the title were "Liquid Nitrogen + Fire = EPIC EXPLOSION!!!" or "My jaw hit the floor when fire was put into liquid nitrogen and then THIS happened!!!" then, yes, I would agree that those would be leading you to expect something... grander. As it is, the title consists of four words, three of which directly describe what's being dealt with in the video. The fourth word is a conjunction and can't really be faulted for being there. If those four words caused you to expect an explosion, it's because you JUMPED TO A CONCLUSION based on the minimal, factual data you were given. The jumping occurred within your own head and isn't the fault of the title. Disappointing? Sure. But that's sometimes what happens when one jumps to a conclusion.

Justintime Thou dhall not like this comment. :D

Saif Khan *Likes.*

I couldn't stop laughing when I saw that comment of yours and you got thousands of likes XD

I still can't believe that happened. XD

You must've been in shock when you saw that lol :D

Thats the animals home so it's still others home

Searl Miranda But it ain't MY home, and the only animals around here are cats

+Carl Bryant He said, "or anybody else's home".

+Carl Bryant *anyone else's home*

+CryEye anyone means any person, so animals "home" doesn't count.

Completely agree. I almost didn't finish my lady semester in college because I stayed home and just watched fascinating documentaries to subjects I NEVER was taught in school on RU-vid and listened to audiobooks and things like that. When I would come into school it felt like a real joke and nightmare for myself - overcrowding, lack of materials, bad attitudes by professors and students alike, complete lack of information and worse, misinformation...money wasted to pay for overpriced GMO crap on campus and expensive metro fare. I have learned more on RU-vid in 4 months than I had my entire 17 years in public school institutions. You have to teach yourself these days with America's teaching institutions collapsing and lack of book stores selling affordable books and closing libraries. If you are really curious and hungry for knowledge, there are public free databases (most require money) like jstor that will give you great academic articles on different subjects going back decades. Have a good one, and keep enrichment alive!

*last semester

Jensen Payne Truly that is good but for god sake these people are at university shouldn't they be a little past the fire triangle? That being said SCIENCE :P

qweqweqwe as Who said that this was at university? Why are you making that assumption. It's even said in the video that these are 8th grade students...

+NightStalker 927 Ummm, no. Pretty sure you led yourself into beleiving that there was going to be an explosion.

+NightStalker 927 XD But wasn't the humor worth the letdown?

I read it as in liquid fire. I don't know what I expected :(

Yep. This is a field trip. 8th graders are (hopefully) much different than college students.

Likely people disliked the fact nobody got hurt.

You don't send 250 8th graders to a national lab without some teachers and parental chaperones.

@@JeffersonLab ok

True. And seven books is a long way around to say "Harry Potter kills a bad wizard." One way is more memorable than the other, though.

Jefferson Lab You sir are the best.

just so you know snape kills dumbuledor

But.... Why.... Why would he do that.... MY LIFE IS RUINED!!!!!!!!

Jefferson Lab HE KILLS HIM????

Some people think it will explode and get angry when nature doesn't oblige.

Jefferson Lab well then... it's pretty screwed up that people actually wanted to see 8th grader space program

I didn't down-vote it, but I was expecting something other than such an anticlimactic show and then nothing afterwards. I've worked with liquid nitrogen myself before, so I expected nothing other than the fire going out, but I was expecting him to maybe try the same thing with liquid oxygen afterwards. The huge build up and anticlimax afterwards is just what makes this video so down-voteable.

Of course, doing anything with liquid oxygen in a room full of middle schoolers isn't the best idea.

>Implying people with headphones use max volume

We have: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1kLsNRPiqco.html

+Jefferson Lab wow your still alive!

I love his experiments....it's so informative.....and interesting too😉✌

Literally O2 ac is rocket fuel

Additional videos are listed in the video description.

Jefferson Lab's Open

Joe Nagle Oxygen is not flammable. Oxygen does not burn.

Jefferson Lab Pure Oxygen is flammable.

Yes, and what i meant to say was that nitrogen puts out the flame, and that fire feeds on oxygen. When there was no oxygen the the tube, the fire went out.

MCAA6556 Pure oxygen is not flammable. Without something to burn, the oxygen has nothing to react with and there's no fire. Take a look at the video where we put a lit match in liquid oxygen. You'll see pure oxygen *NOT* burn as soon as the match runs out: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1kLsNRPiqco.html But, suppose that you're right and that oxygen were flammable. What would the reaction be? O2 + O2 --> what??

Jefferson Lab hmm... I though the pure substance oxygen did ignite in contact with open air.

We're uncertain.

+ABilly05 And who are "They"?

Watch 'Lost'

+ABilly05 it's a common joke, i doubt there was an actual incident.

I suppose. But, considering that liquid water falls from the sky, it's a bit easier to come by than liquid nitrogen is.

Some of the fancy fire suppression systems in high value storage rooms, museums and data centers do use nitrogen (gas) to put out fires. That way you can avoid the problem of preventing things from burning only to destroy them by getting them wet.

Jonathan Nellis I've seen with CO2, never with nitrogen . But I bet that he wouldn't be so brave as to do that with a tank filled with hydrogen .

Eros Viana Intelligence would be a greater factor than bravery.

Jefferson Lab Yeah, I think it would need more dumbness than bravery to do that . Also, great channel, found it today, congrats on it and it's cool that you guys take time to talk to your fans .

Nope. They're *mine*. _ALL MINE_!!!

***** Oh nope. I'd already known Nitrogen doesn't support fire, but he really did make me think it would xD

Iceaka Demintika Then this taught you to trust your own knowledge. So, again, your time wasn't wasted.

Jefferson Lab so insightful :P
