Giant Koosh Ball in Liquid Nitrogen!

by Jefferson Lab • 19,697,207 views

Sometimes, you just want to know what's going to happen! Watch "Let's Pour Liquid Nitrogen on the Floor!" [] if you're concerned about the liquid nitrogen...

So, the first thing you think when you see a squishy fun pink toy is: "Hmm, I wonder what would happen if I put that in a chemical bath?"
totally a breaking bad reference right there lol
Here is an experiment: Let the girl take off the googles and see what happens with the views count.
+Jefferson Lab i am just stating the fact that your videos are more professional and interesting then most understudied people on YouTube not that i am implying that you are an understudied individual just saying that most people do not study these experiments or experiments similar to this one they will simply just throw it in and see what happens.
+Jefferson Lab the great thing about wearing googles is that people goggle at you.
That wasn't as exciting as I thought it'd be...
+cybertree I never said anything about not being exciting, of course Liquid Nitrogen is fun. It's just that the results were pretty much the same as all the other experiments, kinda anticlimactic? I don't know.
Wanna live thousand years? Just take a bath with that,
Pfft... If u feel smart make a science and show to world
Tryed it, doesn't work
I feel sorry for the janitor... like did you just pour liquid nitrogen on the floor?
It just evaporates. 
i was like did they just throw it on the floor do they have a bucket down there  til i saw this second vid lol
What would happen if skin made contact with the Nitrogen??
+Sammy Lane If liquid nitrogen was poured on your skin, let's say your hand, it would most likely just skitter across the palm and fall off unless you're cupping it. This is caused by the Leidenfrost effect. Essentially the liquid never really touches your hand as long as you keep it moving. You can find more of it here: 
+Sir. Velocifaptor And that's fine for a short time. However, people seem to forget that the Leidenfrost Effect isn't free. It takes energy to make and sustain the gas layer. If you're pouring the nitrogen on your hand, that energy comes from your hand. If your hand is losing energy in order to boil the nitrogen, then your hand is cooling down. Given enough time and nitrogen, your hand will freeze. Pour a cupful over your hand? Not a problem (as long as you don't trap/collect it). Let the delivery truck pour its contents over your hand? It's a frozen block of dead meat. Unfortunately, the only way to find the boundary between 'small enough to get away with it' amounts and 'that was way too much' amounts is to sustain injury.
how do you dispose of liquid nitrogen? does it warm up and dissapear? and can anyone buy the stuff??
Am i the only one wondering what will happen if you thaw out those shattered pieces of Koosh ball? Would it be like small rubbery pieces?
If my school used macs, I would be mad . I hate macs. Windows all the way for me!!!
amen to that. many schools used macs when I was growing up. Apple was smart and made their computers cheap for schools so students would use macs and then buy macs themselves. I do miss the day where I could look at a mac in my middle school and spout off the exact specifications of it based on the model numbers. made me look super smart hehehe
Looks like The Big Bang Theory:DDDDD Shaldon and Amy.
This got 19 millions views how?
+Will Ganness Pfft... You think that's a high ratio? Check this one out:
yep that what i think when i see a koosh ball bathe it in liquid nitrogen XD
When a gas gets cold, the particles slow down which decreases the volume, but volume and pressure are inversely proportional in gases, so it imploded because the pressure inside was too high, it doesnt get lower
Your statement directly contradicts what is observed. We see that the ball collapses. A 'flat' ball isn't flat because the pressure is too high. Just ask the NFL. Volume and pressure are directly proportional if the temperature remains constant. Since, as you say, the gas gets cold, the temperature clearly isn't remaining constant. If the temperature drops, either pressure or volume (or both) must also decrease. The ball implodes because the pressure is too low, not because it is too high.
+Jefferson Lab I had to laugh when you said Just ask the NFL.
A bit pretty legit expirement :{ but yea I liked this and Sub you ;) make more videos
Can Science tell me why you still had eMac's?
Because they still do the job that's required of them. No need to replace them if they do what they need to do.
uhm so what happened to the light ball that was inside does it still work? or is it fragile to0? it would have been nice to see it dropped in slow motion...
The circuitry, lights and batteries still work, but there was a loose connection, so the ball part had to be cracked open in order to solder it.
What if i dipped a sandwich in it? Would it be safe to eat afterwards?
+Jefferson Lab you could also mention how freezing things quickly usually results in a better perserved and tasting food.  Ice crystals have less of a chance to form and destroy the food (making it mushy and bland tasting when thawed).  I'm just going off what I recall from a NOVA special i saw about the history of freezing things I saw many years ago though.
About 78% to 80% of air is nitrogen as long its warm its all good!
look at those early iMacs in the back
R.I.P Mr. Pink Koosh Ball 2011-2011
Who's watching this in 2015? Look at those computers. lol
That was really cool how air just turned into a solid except for going to a liquid and then a solid it just skipped the liquid stage

You made my morning/night
yes it is so cold that it boils so when dumped onto almost anything. turns it to a gas. there is no solid form of liquid nitrogen.
Well... if it were a solid, you wouldn't call it liquid nitrogen, so saying that there's no solid form of liquid nitrogen is an empty statement. Saying that there's no solid form of nitrogen would also be quite wrong. Cool liquid nitrogen a bit and it'll freeze. You can see us do just that in this video:
my little cousin (he's 4) thought that they were killing an alien  he's adorable
What's the temperature of the liquid Nitrogen? and another question: if we don't drop the ball and wait until it becomes the normal temperature again, will it still become a NORMAL koosh ball?
The nitrogen is boiling at atmospheric pressure, so its temperature must be 77 K. If you let it warm back up, it'll become flexible again (which you can see in "Light is a Particle!" - but it won't be a 'normal' koosh ball since it ruptured.
Isn't it a liquid that's in those things though
This one was filled with a gas.
We can all take from this video that the PROPER way of the disposal of liquid nitrogen is pouring it on the ground. The more you know :)
There's really nothing wrong with it, as long as you know what you're doing. See for details.
Nitrogen isn't harmful to humans, and it just vapourized as he poured it out
I noticed you were wearing gloves. Its actually better not to wear gloves because the liquid nitrogen can freeze the glove and harm your hand. When you don't wear gloves, it won't freeze your hand because it is sitting on a pocket of gas. If you want to see what happens search for Rosanna Pansino playing with nitrogen.
That is very wrong. Yes, the Leidenfrost Effect will protect your hand for a brief time. However, the Leidenfrost Effect doesn't happen for free. It takes energy to make the nitrogen boil (which forms the insulating layer of gas) and that energy comes from whatever the nitrogen is touching. If that's your hand, your hand gets colder. Keep the nitrogen there for long enough and your hand will freeze. How about a glove? The glove is nearly as warm as your hand. It also causes the liquid nitrogen to boil and form an insulating layer of gas. The Leidenfrost Effect protects the glove just as well as it protects your bare hand. And, just like your bare hand, keep the nitrogen on the glove for long enough and the glove will get cold enough where it can damage your hand. Why wearing a glove is safer is simply a matter of math. To freeze your hand, you need to remove a certain amount of energy, whether or not you are wearing a glove. Let's call this amount of energy H. To freeze the glove to the point where it becomes dangerous, you need to remove a certain amount of energy. Let's call this amount of energy G. If you're wearing a glove, you need to cool the glove and then your hand, so the amount of energy required is G + H. If you're not wearing a glove, you only need to cool your hand, so the amount of energy required is just H. Clearly, G + H is greater than H. If you wear a glove, it takes more nitrogen to hurt you. That's a good thing! You can walk away from larger splashes unharmed if you wear gloves! Recast this in terms of sunscreen. Can you get a sunburn while wearing sunscreen? Sure. But, you get sunburn faster without sunscreen. Gloves basically play the role of sunscreen. Can you get hurt with gloves on? Sure. But, you get hurt sooner/easier without them. One additional thing that the 'don't wear gloves' crowd never seems to consider... Liquid nitrogen makes other things cold, too. Like, that metal bowl. What do you suppose would happen if that were picked up without wearing gloves? The Leidenfrost Effect won't help you since the bowl won't boil and form an insulating layer of gas between you and it... Is that really something you want to touch with your bare hand?? In short, wear gloves.
Where the heck do you get liquid nitrogen/dry ice. I have been wanting to buy some for a long time but I can't find anyone who sells it. Can you tell me where to get it and how much it costs?
Us? We have thousands of liters of liquid nitrogen on-site. If we want some, we just withdraw some from one of the storage tanks. Ultimately, the Lab purchases it from an industrial supplier, such as Air Liquide, Air Products or Praxair. For you, you'd want to find a local welding supply shop. Assuming that you have the training, equipment and knowledge to safely store, transport and use liquid nitrogen, you should be able to obtain some from there. For us, dry ice is more difficult. We don't normally use it here, so we have to go out and buy it on a per-use basis. Happily, one of the nearby grocery stores sells it. Maybe one of your does so as well. A fish market is another good place to try.
What happens if you put a bag of ice in there?
YES Now I have FINALLY see a huge pink ball deflate! Life changed forever! :D 3 minutes and 21 seconds of my life that I will never get back...
Since your time is obviously so valuable, perhaps cruising YouTube isn't something you should be indulging in. Of course, leaving a comment complaining about time that you'll never get back took absolutely no time whatsoever, right??
Yes, you are correct, those are 3 minutes and 21 seconds you will never get back! BUT YOU WILL NEVER GET ANY TIME IN YOUR LIFE BACK! Unless you can time travel into the past and change what you did in those 3 minutes and 21 seconds! 
"A while ago I was at the mall, and I saw this, and the first thing that popped into my head was 'I wonder what would happen if we were to put this in liquid nitrogen.'" That was your first thought?! O~O
Um...death would happen,slow and painful death vinyl.
Half price.  It's as if they were practically begging you to soak it in liquid nitrogen.
IT'S ALIVE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!=OAHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!
The fact that this video has 18 million views gives me a small shred of hope for humanity.
Yeah, because a science video with many views is just so dumb.
Those are some old school computers...
Is Liquid Nitrogen similar to dry ice???
Not really. One is nitrogen (N2) while the other is carbon dioxide (CO2). One is a liquid while the other is a solid. One boils while the other sublimates. There really isn't any likelihood in confusing the two.
the ladling was bad science, atleast without measuring when you began and at what rate with what volume ladle.
+lobyouster It's about two liters. It's still around... somewhere. We can determine it's volume more precisely if you need us to.
This is the only reason they got big lmao.
Yeah. It's kind of ridiculous.
Do you know what happend if you put dry ice on nitrogen liquid ?
Yep. We even have a video of it. You can watch it here:
You uploaded this un my birthday
those macs in the background are pretty old !
Yep. And the wall behind them is even older. For the moment, they both do the job that's required of them, which is nice.
:) That will never get old...
It's filled with air that's obvious why would It be a children's toy if had a gas that could harm a child in it
You don't know what it was filled with. It's a good guess that it's filled with air, but a guess isn't a fact. There are manufacturing reasons why it could be filled with something else, such as nitrogen gas. Like air, nitrogen wouldn't harm a child. So, without testing (or contacting the manufacturer), neither you nor I can say for certain what it was filled with. All that we know for a fact is that it was filled with some sort of gas, which is why we said that.
Why are you using gloves? Liquid nitrogen could freeze the gloves and give you frostbite.
Ever heard of the ledenfrost effect?
+R3D Nebul4 Did you read the thread before commenting? We've already discussed the Leidenfrost Effect's role in this and why it isn't magical cure-all that some people make it out to be.
Not expecting a hollow object full of air to self destruct in liquid nitrogen?????
Not all hollow objects full of air self destruct in liquid nitrogen, so it wasn't a forgone conclusion.
This is so cringe-worthy. I don't know why but it just is o_o
When do you do the liquid nitrogen live shows in newport news
We do them throughout the year. Use your search engine of choice and search for 'jefferson lab physics fest' to find the current schedule.
How did the ball inside not break
The primary reason is that they are made from different materials.
when was this filmed those apples in the back are ancient
The filming date is pretty much the same as the posting date.
+Cleverconure No more than ice is a chemical reaction. It took a reaction to make the nitrogen (N2), or the water (H2O) if we're talking about the analogy. But going from a gas to liquid (nitrogen), or water to ice, is a physical change. No chemical reaction is involved.
+Jefferson Lab Yeah, you're correctus. Its only a physical change. Its been a while since i've studied physics and chemistry; i get confused between chemical change and physical change.  The reason i said it was a chemical reaction though is that well, i meant physical substance i guess you could say =P. I knew i said something misleading.
If you were to keep the koosh ball in there long enough, and you would take it out and  thaw it, would it turn "rubbery" again?
This was... disappointing. Why was it unexpected, that the thing" self destruct"? you freeze its surface, and the gas inside is still contracting. Well,
Because of previous experience, primarily with balloons. See or or They collapse, but don't self-destruct. As was stated in this video, since the giant kiosk ball is sort of like a balloon, it might behave the same way.
Did you have to tidy all that up
Of course. It's rude leaving bits of shattered kiosk ball scattered about.
why do u have such an old pink scooper thing and old computers also why is the first thing u think of when u see a squishy not koosh ball air filled thing u think of putting it in liquid nitrogen
Ladle - Once you find one that survives being in liquid nitrogen, you stop looking for a ladle. Computers - They still do what we need them to do, so why replace them? Koosh Ball - Why wouldn't that be his first thought? Something has to be the first thought. When you have nearly instant access to practically limitless amounts of liquid nitrogen, such thoughts happen naturally.
yo no hablar muto inglis y no entenderid at video 
Well, that's not really a surprise, considering that it's in English. You could try using the translation feature with the closed captions.
Wow! That's a very messy way of doing an experiment. Cool one though.
Possibly, but don't you think Liquid Nitrogen needs to be handled a bit more carefully? :)
+TechAztech No. Proper safeguards were in place and, believe it or not, reasonable procedures were used. Remember... This is all planned. How we make things look on video isn't necessarily how you would perceive them if you were in the room watching.
So if I die and I place my corpse inside of a Liquid Nitrogen bath, will my body look the same forever?
If you're dead, you aren't placing your corpse anywhere. But, should someone place your corpse in liquid nitrogen, it won't decay. If they don't do something to remove the water ahead of time, it probably won't look the same, but it won't rot.
+Jefferson Lab C'mon you know what I mean. If my corpse gets placed in a Liquid Nitrogen bath.
Where did you get that pink thing
From the mall... We say as much in the video.
Wouldn't it be better practice to know what the actual gas is inside?
+Jefferson Lab What if the gas inside the giant kiosk ball was harmless until exposed to nitrogen gases?
+recipeez 78% of the air is nitrogen gas. If the gas inside the ball became dangerous when exposed to nitrogen gas, then we're back to lawsuit city after the first one gets cracked open by some kid.
Absolutely. It's very basic and very simple, but it's still science.
Now I know what to do with liquid nitrogen!
Not talking about the comments  about taking a bath in it.(raditya armstrong)
oh i knew it was gonna pop.... im 13 o-o. is there scientific evidence of reasons it WOULDNT? i thought that was common knowledge :I
Balloons don't pop - "Liquid Nitrogen Experiments: The Balloon" Racquetballs and ping-pong balls don't pop - "Liquid Nitrogen Show!" So, yeah, there's reasonable expectation that the kiosk ball wouldn't pop.
This is in Virginia, right?
Yes. We're in Newport News, Virginia.
Dude, if I worked at Jefferson Lab. I would steal all their nitrogen and create a spiderman sort of webbing, but like it sprays liquid nitrogen instead. I'd be Nitro Man.
We have something like 80,000 liters on-site, so good luck with stealing it all. You're going to be sloshing...
why would u just dump liquid nitrogen on the floor?
To get it out of the bowl.
You are wasting nitrogen like that.. It cost a lot
+Jefferson Lab I wasnt aware of that..  than its feasible.. but somewhere in the net they said it cost hundreds of dollars.. for small size bottle.. !!!
+Prem Krishna Chettri The containers are expensive, but the containers aren't nitrogen. This is a little like saying that gas costs a lot because you have to buy a car to put it in. The largest tank we use in these videos costs about $800, but it only holds about 50 cents worth of nitrogen.
Why does this pop but not balloons?
I think it's primarily because the 'skin' of the koosh ball is much thicker than the 'skin' of a balloon.
that was the most boring video on youtube i have ever seen
It's your first day on YouTube, I'm guessing? Because there are lots of other videos that are way more boring than this.
Why?  Because why not!
I know, right? Something like that is practically begging to be put in liquid nitrogen.
Here's something else that is begging to be dipped into liquid nitrogen.  Anything running on iOS or OSx.  Or test samsungs everything proof phone. 
No, you really don't.
The most expensive way to destroy a Koosh ball
If that's what you think, then you don't have much of an imagination... More Expensive Way #1: Hire Liam Neeson to track the giant koosh ball across the globe, where he eventually catches and destroys it. More Expensive Way #2: Build a rocket and launch the giant koosh ball into the sun. More Expensive Way #3: Create an anti-matter giant koosh ball and introduce it the the regular matter giant koosh ball. Liquid nitrogen, being about 25 cents per gallon, isn't really all that expensive.
I heard someone say that you shouldn't wear gloves when manipulating liquid nitrogen because it just falls right out of your hands and doesn't really do much, but if it's caught inside your gloves it could be really bad.
That's why the gloves are loose-fiting. If nitrogen should get into them, you take the gloves off. Did you watch the entire video? Towards the end, when the metal bowl is picked up... If your hands were bare, what do you think would happen to them? It's a choice between 'maybe something bad happens if nitrogen happens to get into the gloves' and 'certain, severe, and quick damage happens without the gloves.' Which do you choose?
+Jefferson Lab yeah in the other video i watched they used some kind of pincer to pick up the object they were freezing. But as long as you're careful i guess it's ok! i just said it in case you hadn't considered, i thought maybe it was dangerous.
How Much is the nitrogen? In the USA
For us, about 25 cents per gallon (~6 cents per liter).
one could easily suspect it would have popped (I thought that before watching the video) because the plastic/rubber would become rigid with the cold. After that, the gases contract, and there would be negative pressure. This would cause it to pop
Maybe. Maybe not. It depends on what your past experience is. As was mentioned in the video, balloons don't behave that way. They contract, but they don't pop. If that's your frame of reference, and you think of the koosh ball as being like a balloon, it's completely reasonable for you to expect it not to pop.
like to fill a water gun filled with Liquid Nitrogen and shoot it at people 
Did he really just Dump liquid nitrogen on the floor
Why were you at the your old
I came here to laugh not to learn
+oopsy444 If we can only provide one of those things in three minutes, I'm glad it was the latter.
Hey y r u wereing gloves the gloves could get stuck to you skin don't were gloves next time
Sorry, but you don't know what you are talking about.
Destroying the world for a stupid experiment...
The video is about 4 years old and the world is still here. So, false.
I'm walking down the street and i see a pup i wonder what will happen if i put it in liquid nitrogen ?
My prediction? You get arrested for animal cruelty.
Was this suppose to be comical? I don't get it...
Watch this vid till the end the end it funny.THANKS TO jayden to recommending this vid
nice vid! but what was that silver ball @3:10??
It contains the circuitry and batteries for the giant koosh ball's light flashing system.
Ugh!!! Too much science talk! Next time just freeze it and break it!
This is a science channel. The fact that there is 'science talk' shouldn't be much of a surprise.
You all know it's 2014?
ooooooo you might want to apply some ice, you just got burned by Jefferson Lab
it even says uploaded feb 1, 2011
"it isn't collapsing...maybe it will" but then 2:31 popbufgdh!!
Why are they just pouring nitrogen on the floor Is that even safe I was like😱
Wow their hypothesis supported their data
Other way around. The data are what they will. They either support the hypothesis or they don't.
So, take action and watch something else. We won't be offended.
