Liquid Nitrogen and a Light Bulb

[TheMihig]

next time use liquid hydrogen :D

[zaxtor]

I always thought liquid nitrogen would destroy the filament like oxygen.

Also how long the bulb would last if you wouldn't pull it out?

[asadparvez2]

That sounded like poop!

[MrSkateify]

@asadparvez2 Wtf? What kinda poops do you take? lol ;)

[asadparvez2]

@MrSkateify lolz

[Pakman332]

soo the liquid nitrogen keeps the filament cold so it wont burn up when you turn it on?

[joeylawn36111]

@Pakman332 Keeps the Oxygen in the air from burning up the filament, as happened shortly after removal from the liquid N2.

[FlashXX97]

Now you know how to save electric bills.

[smokinleaves]

is this legal?

[webmastertool]

@smokinleaves no but that sure as hell isn't going to stop me from doing this. fuck fbi friday.

[XWHITEoKNIGHTX19]

liquid nitrogen+mercury=world wide devestation

[hr1100]

SCIENCE!

[bioshock2bigsister]

yes, the nitrogin has enough stored energy 2 power a light bulb....du!!! i knew that and im in 7th grade

[ID0NotCare]

@bioshock2bigsister Work on your English next.

[bioshock2bigsister]

@ID0NotCare indeed.

[Geekv2]

@bioshock2bigsister The lightbulb isn't being lit up by the liquid nitrogen, it's being lit up by the electricity they're putting through it. The liquid nitrogen is boiling because the lightbulb is getting hot, as they normally do. This is demonstrating that a bare lightbulb filament, which normally burns up when the glass is broken because of excessive heat, doesn't burn up when dipped in liquid nitrogen.

[346L3]

@Geekv2 It doesn't really burn up because of excessive heat, as a lightbulb is not cooling the filament in any way. It does because the metal comes in contact with oxygen and burns through, so it doesn't matter if the nitrogen is liquid or gaseos: as long as the filament is in relatively pure nitrogen it won't break at normal voltage.

Lightbulbs are filled with protective gases like Argon and old ones were simply evacuated, so the vacuum inside contains too little oxygen to oxydize the filament.

[mynameismatt2010]

@bioshock2bigsister Yes something hundreds of degrees below freezing has "stored energy" You may want to speak with you previous science teacher for some clarification.

[TheRealShadowspawn]

When I was in 3rd grade a guy put on a show with liquid nitrogen; had a motor and did all sorts of "cool" stuff. We weren't allowed to handle it but we were able to give things to him to see what happened. Rubber/tennis balls shattered like glass, balloons turned into pancakes, and yes, there was a lightbulb. I can show my son this. Thanks for the video!

[AlacerIgnis]

now, put ur finger in...

[Y0uNG0ne619]

Lol sounds like a bong toke

[GoldenKnight422]

considering how delicate the electrical lighting element of a light bulb is I am surprised that it survived the sudden temperature difference plus the movement of the boiling liquid nitrogen

[walkandlookup]

@GoldenKnight422 there are two facts the filamente will stay lit due to the lack of oxygen and there is less resistance because LN is about -198ºc as you can see the filament lasted barely two seconds in air

[Jerkwad152]

Good thing it wasn't liquid oxygen. =D

[RaudelSolis]

@Jerkwad152 lmao boom!

[greenrolaids]

@Jerkwad152

or nitroglycerin.

darr

[iToasterman]

omg ._. boiling liquid nitrogen wusing electricity :D!!!!!!!!

[Ochn77]

I LOVE LIGHTBULBS! HHHHHAAAAAAAA!

[bulkytinktink]

nice camera quality

[rpknight12]

Is it plugged in?

[guitarhero3rox97]

@rpknight12 no shit sherlock

[homeyG75]

@guitarhero3rox97 That's not really the right time to say "no shit sherlock"

It didn't show that it was plugged in

[nugget0428]

@homeyG75 fuck man... ur just as retarded

[btsouthmost]

Sounds like someone smoking out of a bong

[Dagg215]

epic win

[matchbox2022]

LN2 bp = 148ish C

[videocritic2463]

wtf its boiling

[sorakeybade1]

itz becuz Liquid Nitrogen has a boiling temperature of -196 degrees celcius i believe, so virtually anything u throw in liquid nitrogen will cause it to boil

[htirah100]

@sorakeybade1 is it dangerous if liquid nitrogen is exposed at ur skin

[sorakeybade1]

@htirah100 It could be, dependin on how cold the contact is when you touch it. If you pour it on a table and let it boil for a good 2 seconds b4 touching it, its pretty safe. But if you pour it on your arm, then u have some problems

[htirah100]

@sorakeybade1 update i just findout somethin that is called the leidenfrost effect the liquid nitrogen is safe cos there is like a cusion from the vapour that makes it not to have contact with ur skin

[123chea123]

@htirah100 yeah that only lasts for a few seconds before it starts to kill your skin cells and etc

[htirah100]

@sorakeybade1 but after a while when its stops boiling,then you can turn ur hand into meat popsicle i guess

[somard1]

i friggen love liquid nitrogen

[ballonman124]

@somard1 where can one get it?

[somard1]

@ballonman124 no idea but i just love it :)

[ynonn1000]

@somard1

I LOVE EVERYTHING ABOUT ICE, DRY ICE, NITROGEN

ESPECIALLY I LOVE ITS COLDNESS

[somard1]

@ynonn1000 okay enough with the caps please

[ynonn1000]

@somard1

OK BUD!

[somard1]

@ynonn1000 .-. lol

[OmgThereGoesMiranda]

Now THAT is awesome.

[OgamerNL]

Really nice :D

[wictro]

I think that the reason for not burning out is also that metal conducts electricity better if cold (supra conductors)

So it does not heat that much, thus is cooler.

On second tought it glows, so it has to get hot to do that.

Maybe a combination of no oxygen and better conducting.

.wic

[gennaman2bit]

Heat is over 2000-2200 °K, the light is yellow...

[infinitemes]

where do these people get liquid nitrogen from?!

i want some :[

[cowgoesmoo2]

ebay????

[gytiw79]

Wait till 18 and get a job at chemical fabric and wala! Ask for some liquid nitrogen there!

[madjimms]

@infinitemes Your local hardware store.

[iseesquares]

that's awesome my grade 6 teacher taught us about light bulbs and how there is an inert gas inside the buld so the filament can't burn i guess liquid nitrogen does the same job :)

[srmaietta]

in a bulb is inert gas. no oxygen = no burning of filament. In liquid nitrogen = no oxygen, no burning out. simple. COOL!!!!!

[dmanewas]

awsesome!!!

[salmiak911]

Not all lightbulbs ( or maybe noone? ) have complete vacuum. It has nobelgases ( not sure about mywording ) like argon.

It would be cool to just drill a small hole in the bulb and fill it up with liquid nitrogen ( or gasoline ;D ).

[bunyanjo]

Cutting edge science guys.

[crazn20]

No guys, normally an intact lightbulb is in a vacuum so it doesn't burn out but since liquid nitrogen is so cold, it prevents the filament from burning out which explains why when he pulls it out of the liquid nitrogen, it burns out.

[SETHHIKARU]

No it's not under a vacuum, it's an inert gas that they put in the bulb after they put it under a vacuum.

[unit10251]

OMG.. THATS SO COOL..

[braveryhawk]

I KNOW!!!

[moosey333]

Hmm, are light bulbs filled with argon or a vacuum? I don't remember right now but if it is argon I would try a intact lightbulb without a power source and liquefy the argon. Well, actually if would be difficult because the melting point of argon is very close to the boiling point so you might even end up with a solid.

boiling point = -185 *C

melting point = 189 *C

[Unlovedhero5]

vacuum

[TootieLouLou11]

How does that work?

[tehklutzking]

In the bulb with it not broke it keeps it from over heating it has gases which slowly exorb heat. But when you put just that in some thing sub zero temps it will keep it from over heating an blowing out!

[Zenodilodon]

Actually no, in order for things to burn up, anything for that matter oxygen is required, filling a lighbulb with argon or a vacuum remove the oxygen from the tungsten filament's environment

[Dalemoooooon]

to re-write what that guy just said so it makes sence..... inside the bulb there are gasses which stop the fillament instantly burning out (like when they took it out of the liquid nitrogen) so basically putting the un-protected fillament in the nitrogen will be the same as being inside the full bulb.

[Unlovedhero5]

it cools off the filament. The reason air is vacuum out of light bulbs is because if there was air, it would heat up and break instantly.

[gumdrops27]

thats crazy!!!!!!!!!!!!!!!!!!!!!

[lordofgangstas]

AWSOME and thats the power of LIQUID NITROGEN ITS A LIQUID MIRACLE!!!!!

[swissair10]

no there's no miracle - just physics ;)

[beto9298]

why does that hapen

[chinesekid05]

it made a farting noise XD

[WaffleManForever]

that was cool

[anonymousguy2007]

its because they use nitrogen in lightbulbs

[colledge123]

no its because the nitrogen cooled the nitrogen and kept it away from oxygen so it didnt burn out

[eatingjif]

makes no sense mate

its because there is no oxygen so the fillament wont burn out and nitrogen is also inert so no wierd shit happend like a fire

[contentlocked99]

the liquid nitrogen is so cold that the filament boiled when submerged in it.

even if the light bulb is cold to the touch it's still extremely hot in comparison to the liquid nitrogen.

[eatingjif]

well done

[jonahkwok]

they use argon, not nitrogen.

[anonymousguy2007]

correction thanks to jonahwok argon not nitrogen

[3709280]

cool

[Gaunc]

holy shit
