How to make this video more 100 times more interesting.
Replace liquid nitrogen with liquid oxygen.
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
I like this dude, he's the kind of dork that makes school fun... wish I would've had teachers like that
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
Did I seriously just sit and watch for 8 minutes only to find out that fire goes out when there is no oxygen?
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.
7:10 he needs to have a fake hand in there already and pull it out and smash it on the table..
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
That has to go down as the best trolling in history of chemistry.
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
*tries it at home*
Why not

anywhere else except home
Amazing story teller.
Victor Kyrg being a teacher is 40% teaching 60% story telling.
we need more teachers like this guy

How did I get here
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. CZcams 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.
This was very interesting. Why so many dislikes?
You are one awesome teacher. I would love to attend your every class :)
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.
Yall upset cause he tricked you guys into thinking that it was gonna explode and used that trickery to teach you a chem lesson. Don't be upset cause he's a good teacher.
+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?
This guy looks like a fun teacher
I don't get why there are so many dislike. He obviously knew the candle wasn't going to blow up. He wanted to make the kids feel agitated and expectant, only to throw them a disappointing fact that nitrogen doesn't catch fire. It's how people will learn.
Or was it because he didn't dip the burning candle into the liquid?
There's really no point. Nitrogen, liquid or gas, simply won't explode or catch fire.
Lol at everyone who came to watch this video looking for explosions. Don't you watch enough of those on TV?
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. ;)
I was hoping that something self oxidising would be tossed in to create some kind of explosive expansion, instead, disappointment.
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 CZcams. also aren't those college students
Shiggity Shwa The bar is set higher when it's put on CZcams? Have you spent more than five minutes on CZcams?? 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.
I just wasted my 8:22 minutes of my life.
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
Epic way to learn. I remember in HS we were playing with Liquid Nitrogen in AP Chem... Was fun and the teacher froze random stuff like candy and ice cream lmao
Those adults looked PISSED when he made all those death by explosion jokes XD
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.
This guy is exactly like my art and graphics teacher with the tricks and jokes.
This guy just plays with the audience so hard.
5:27 That guy is a really good troll
Trolololol
OmGWtftRolOlOLolO!
Yeah something like that :OoOoOoOo
Science teachers are the original trolls.
people who expected an explosion and left a dislike are sad human beings :D
Corkoth55 only people that disliked
"comes to see explosion" darnit.. all I did was learn...
I deeply appreciated this video. I am in college majoring in science, and I had picked the "N2 will just put out the flame option", but was still on edge and built on suspense that I was probably going to be proven wrong, SOLELY based on the fact that you seemed to be inferring that an explosion was going to happen. Not only had I anticipated an explosion the first time, but also the second.
This video really teaches the importance of learning how to think for yourself and trusting the laws of the universe to be able to predict outcomes, and not the spoken word of somebody else. I also think you made the whole experiment much more exciting through your presentation, and more likely to be remembered than if you had presented the experiment plainly. The result was honestly disappointing, but if one could see the beauty in the disappointment, a deeper appreciation for our judgement could be obtained.
Is there more videos by this teacher?
Does he have a CZcams profile?
+Sion Additional videos are listed in the video description.
Great video, why so many dislikes? Am I missing something? Teachers like that are what inspires kids to get into science!
are you serious
@@official-obama are you serious
The answer to what would happen was so completely and utterly obvious that I felt it was so obvious that I clearly must not be thinking of something.
This was designed to troll. This trolled. 10/10
Wish I had a science teacher like this. :/ Mine was just... "Here's the book, read these pages while I go sit at my desk until the bell rings."
I'm not even kidding. He was the _worst_. Most boring teacher I've ever had.. And I had an English teacher who spoke in monotone.
That's like mine but she's a girl so...
Loki Laufeyson And they say it's hard to get a job...
Are you telling me in College in America, they learn that Oxygen is needed for fires? Are you being serious?
***** 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.
Sounds stupid but it would have been so cool if the actual flame froze.
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
it is so simple... there is no oxygen
+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
Thank you. Comedic, fun, watchable. And to those who complain that they know everything -- contribute something. From doing so, you'll learn to appreciate those who genuinely do.
Great teacher, dont get why all the hate here
*****
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.
I love when this video pops up in my suggested for you on CZcams every other month, I watch it every single time! Thank you for making science fun for young & older kids alike!
Amazing teacher. You kept the entire audience engaged in the entire experiment. Wish that every teacher were able to do this.
I can stick my hand here.... class dismissed, and can somebody get the nurse?
I hope this man teaches with as much passion today as he did back then. Such a great chemistry teacher. Makes it fun for everyone involved, which leads to a more memorable and enjoyable experience. Teachers like this lead to students wanting to pursue careers in science.
Not the best explosive reaction with the experiment(no kaboom), but the professor(Steve, as I creepily found out) seems like a great teacher that enjoys what he does, and you can see that he makes the students enjoy it too.
Best troll ever.
try liquid hydrogen
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.
Well that was 8:00 of my life i will not get back
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.
Honestly, did anyone expect anything different? I mean, yeah, when you deprive fire of oxygen, it tends to go out, duh.
+PremierMilenkov A room full of people and, currently, about 7 million more on CZcams 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.
Geeze I wish i had classes like this when I was in school. I always loved the sciences but the professor was so dry and boring I ended up losing interest
Hmm not what I expected but I like the teacher^^
(Edited 'cause of some spelling mistake ^^')
I'm an relatively new educator and I (with love you science ) find your presentation remarkable and very well done. Hats off to you, sir.
Your replies to the comments are actually the best part on this video page.
19482 people who disliked this are probably big fans of Michael Bay.
lol hes a good teacher
He is a really good teacher
I LOVE this guy. Wish I could have a teacher like this. If schools had teachers like this I'd love to go to school lol
I jumped when he hit the table
so nobody knows air is almost 80% nitrogen?
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.
Why so many thumbs down? I think that was a fine presentation.
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.
Fascinating!
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
Nobody twisted your arms to watch this video. These are 8th graders, or so was mentioned in the video. A lot of people making troll-like comments about wasting their time, you look a lot older than the 8th graders. Try saying something that helps with the conversation instead of whining because you were expecting an explosion and it didn't happen. A little common sense and maybe a little research will get you a long way.
I will not try this at home or anyone else's home... Get the keys! We're going to the great outdoors!

This is what news on TV should be about, education, absolute hilarity, and enjoyment, rather than war and negativity and politics and BS. Thank you for bringing joy. I will share this with my family and my friends. Keep doing what you’re doing you make life so much fun.😂
I learn more from this channel than I learn at school.
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 CZcams 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 CZcams 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...
chuckle, wish my teachers had been that cool
Awesome teacher!
Def a cool teacher!
At least this isn't a college, it looked like one at first, would have been so sad for roughly a third of college students to be thinking that the fire would get bigger/explode.
Yep. This is a field trip. 8th graders are (hopefully) much different than college students.
i bet most of those dislikes are because they thought they were gonna see an explosion
the title lead me to believe that there was going to be an explosion.
+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 :(
this teacher is amazing!
Wait, What? Why so many dislikes?
Likely people disliked the fact nobody got hurt.
( 5:15 ) That's one big 8th grader.
You don't send 250 8th graders to a national lab without some teachers and parental chaperones.
@@JeffersonLab ok
Wow long way around to say nitrogen settles and doesn't support a flame
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????
why does this have so many dislikes??
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.
I don't know why there are so many dislikes. This video is pretty fun to watch. Probably too many 12 year olds expecting someone stupid messing with explosives so they could laugh at how their hands get blown off.
It was fun seeing how you play around with the kids :P
The answer was easy to tell from your humor but still.
Please. please try it again, but with liquid oxygen!

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

Jefferson Lab's Open
Only now that I’m watching it, I find it cool that I watched this stuff once in person
Definitely someone who knows his showmanship. Would have loved to have such teachers, makes a lot easier to remember.
Omg the best teacher these students are so lucky
Apparently these kids forgot about their 4th grade Chem class.
I watched this a LONG time ago and forgot all about it. Well I have to say he got me again.
Perfect example of a good teacher that makes the class interesting. The answer to this was quite clear but he makes it fun and interesting. If all teachers where like this, grades would be so much higher!
At the beginning when he asked the kids what would happen, i knew right away. We learned this in IPS, when we read a book called the Disappearing Spoon. For fire to stay lit, it needs oxygen, which is flammable. Nitrogen has the opposite effect, it snuffs out the fire.
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:
czcams.com/video/1kLsNRPiqco/video.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.
Really enjoyed the video. Great teaching style
I laughed out loud when he hit the table. that was perfectly timed and well executed.
I added this to my watch later so many years ago and hadn’t got around to watching it until now. Even in 2022 almost 2023, we don’t have teachers half as good as this man!
I wish this guy was my science teacher! xD

What is Heisenburg doing on the far right?
We're uncertain.
Excellent presentation, great rapport with the kids! Thanks for doing what you do, even with the dad jokes =)

Watch 'Lost'
+ABilly05 it's a common joke, i doubt there was an actual incident.
Best....Professor....Ever.....
Wow....what an awesome teacher! They are enjoying this lesson so much, they don't realize that they are learning!
its teachers like him that make you not forget stuff, with examples!
Well, I suppose that we could conserve water with the fire department and just shoot liquid nitrogen at blazing inferno :p
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 .
Give back to me my 8 wasted minutes of life!
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
From one teacher to another, this was great.
Great teacher! He sure can make his student pay attention.
