Liquid Nitrogen Experiments: The Rubber Stopper

[TheAgent3000]

Try boiling liquid nitri

[erikdude1111]

How many times do you practice your scripts? No joke, please reply?

[JeffersonLab]

@erikdude1111 Not a whole lot. Lately, there hasn't been time to rehearse before filming day. We'll do general practice as the video equipment gets set-up and then 'scene specific' practice just prior to filming those segments. Maybe 5 or 6 run throughs before the camera rolls and then probably 4 or 5 actual takes. It's not the best way to do this, but scheduling additional time for rehearsal is usually even more difficult.

[Soo7izStudio]

So much fake excitement .. :L

[videoman5747]

Whoa the rubber stopper exploded right after you went under the table that is what I call perfect timing.

[JeffersonLab]

@videoman5747 Well... Editing does exist...

[kosikko4400]

@JeffersonLab "Whoa the rubber stopper exploded right after you went under the table that is what I call perfect timing." irony :D

[gaylordman123]

Can liquid nitrogen freeze

[JeffersonLab]

@gaylordman123 Yes. See our video called "Let's Freeze Liquid Nitrogen!"

[robertjamieson421]

How can any random person obtain liquid nitrogen not saying ur random asking for myself

[brandola1971]

What would a book in liquid nitrogen look like

[brandola1971]

How do u get liquid nitrogen

[JeffersonLab]

@brandola1971 We get liquid nitrogen by going to the Test Lab fill station.

[brandola1971]

I like things that explodes :)

[evewingful]

What would happen if you put a book in liquid nitrogen?

[ninryokuandpie]

@evewingful Ooh good idea.

[SNWijesekara]

Hay Steve try a piece of K(potassium)

[JeffersonLab]

@byehiguy No, not really. Unless it's really wet, wood can handle it fairly well. We usually do our demonstrations on wood tables for this reason. We completely destroyed a plastic table in the past...

[The31073]

wasn't the ducking was a bit anti climatic?

[livenlearnify]

you should try submerging a test tube like halfway in liquid nitrogen and see if you get liquid air in it

[JeffersonLab]

@livenlearnify You do. Take a look at our 'Behind the Scenes' video. You'll see that's what we used to get 'pure enough' liquid oxygen to use in a couple of our experiments.

[lemkelegion]

i have a qustin what would happen if you put something extemly hot like a liquid metal like in nitrogenand what would happen to liquid titanium.

[JeffersonLab]

@lemkelegion It depends on how much nitrogen you have and how much molten metal you are pouring into it. Must likely, you would flash the nitrogen to gas. Do it with large enough volumes and you'll have a bit of a gas explosion on your hands.

[askyurself]

i was shocked by that detonation..hahaha..how many minutes does it take to explode?..because after you ducked..it just *pop!*..

[JeffersonLab]

@askyurself The time varies a lot and it wasn't possible for us to predict when it would go off. 5 to 10 minutes is about the timeframe.

[Almontmarine]

do you have extremely hot stuff, like liquid gallium or liquid copper?

[JeffersonLab]

@Almontmarine Not normally. We usually go through great lengths to keep things cold. The hottest place we have here, other than our electron beam welder and the business end of our Free Electron Laser, would be the beam dumps at the ends of the experimental halls. Melting that would be very bad, so we raster the beam over the dump's area so the heat doesn't build-up on one spot.

[IKickedurassdontcry]

lmao self destruct mode sequence

[lukeogawa]

Wats a stopper?

[JeffersonLab]

@lukeogawa It's like a cork. You put it in the opening of a test tube to stop things from spilling out.

[koreath]

awsome!@@!!@!@

[Jon58004]

i think the stopper would melt if you put it in a hot area

[JeffersonLab]

@Jon58004 I agree. It probably would.

[ilovekirky1]

haha

[FlumenSanctiViti]

From this video we can see that if we place warm rubber stopper in liquid nitrogen, it explodes.

However, if we were to place frozen rubber stopper in hot area, would it make it... implode??

[JeffersonLab]

I think it could still shatter. When we cool the stopper, the outside gets cold and contracts while the inside stays warm and doesn't. The stress that this creates eventually leads to the failure of the stopper. Putting a cold stopper in something hot would do a similar thing. The outside would get warm and expand while the inside would stay cold. There would still be a build-up of stress. Whether or not the stopper would fail would depend on how quickly the outer layers regain their elasticity.

[lyzergnature]

-gasp-

[lightmobile]

sweeeeeeeeet!!!!!!

[nebonit]

Wow, I am so going to do that

[nikki638]

where's they get the liquid nitrogen? could u make it at home?

[JeffersonLab]

We get our nitrogen from an outside vendor, which doesn't really help you that much. I'm guessing that you intended to ask where *you* could get liquid nitrogen. Companies that supply gases to welders typically carry it. Look in the yellow pages under 'Welding Supply' for a company in your area. Be aware that you can hurt or kill yourself with it if you don't handle it properly.

Could you make it at home? It's possible, but it's far easier to buy it.

[Tristanvash38]

5/5 for popping rubber stopper popper copper whopper

[MrGameAndWatch00000]

LN2 is awesome, bought some last year

[TomCatFort]

Was it expensive?

[MrGameAndWatch00000]

Not Steves Faverite stopper!

[ginjerninjer]

that ws funni.

buy why go under the table..??

XDD

[JeffersonLab]

If you aren't sure how big the explosion is going to be, you hide. There is no shame in fleeing the stopper.

[tutorialconr]

I love you guyz!

[JeffersonLab]

Yes. Steve was distraught for days afterwards.

[freak60763]

xD 5/5 i loughtd at the pop, i do that too :)

[b0rjas]

the pop made me jump!!! 5/5
