liquid oxygen in microwave.

[ohklunkme]

oxygen doesn't ignite, it basically makes things u ignite ignite much more violently....

[smallroyden]

"Do not try this at home, try it at an apartment! j/k. cool vid!

[marklandynut]

The fuel used in the space shuttle is liquid HYDROGEN. Nitrogen is extremely unreactive and many of its reactions absorb energy rather than releasing it. Hydrogen by comparison is very reactive and releases a lot of energy, especially when reacted with liquid oxygen.

[marioescalante68]

Can you breathe in the liquid oxygen?

[Flydeification]

@marioescalante68 Its extremely cold something like -220C. it would freeze your throat, lungs and wont allow any oxygen pass through into your blood stream.

[ChemCrazy81]

This is fake, just like the cesium/rubidium video from Brainiac. They were disappointed with the results of LOX/steel wool so they blew up the microwave, just like the bathtub.

[boris3650]

and here you have a rocket motor XD

[rockbaskit]

Fake and gay

[Schwedler]

why there is black smoke at 0:50 ? ^^ .. black smoke is comming from carbon^^... and there's no carbon contending material burning.. only oxygen with iron.. so i would say that this is a fake ;) .. oxygen is an oxidizer and not a fuel, it can't burn -.-

[Deamonic]

@Schwedler shockingly enough, the materiel comprising the MICROWAVE itself contains Carbon, Especially the plastic outer housing. there are very few things in our world that don't contain some small amounts of carbon.

[spartoon110]

I think I'm gonna try this at home

[soulles2002]

Hamster are you even sure you know what your talking about you should probly leave this to james may lol

[thewii552]

fake. O2 is just an oxidizer-not even rocket fuel. it is used with hydrogen to power a rocket. However, it cannot be lit with a match...and certainly won't do that!

[JZ41523]

lol that guy turned it on and got the fuck outta there lol

[juneya04]

STFU hammond just blow the thing up already

[jhafanador69]

is it just me... or does that look and sound like the guy from top gear?

possibly him?

[johnnynaillon]

@jhafanador69 He is the guy

[biw1]

@jhafanador69 yes it is richard hammond...

[DieterMe]

Don't try this at home... bla bla bla.

[justonium]

The explosion wasn't caused by the liquid oxygen. The video is legit up until the explosion though.

[libtechsk8er]

Somehow I think they used explosives in this video to make the effect more dramatic, just like they admitted that they did with the alkali metal demonstration.

[quosmo1]

@libtechsk8er yeah the black smoke that rises in the fire cloud looks a lot like a petrol explosion not the bright fast burn of liquid oxygen, but slower and colder petrol fuel burning.

[libtechsk8er]

I love liquid oxygen. I can condense small amounts of LOX using liquid nitrogen. I got a job so why not spend $500 on a Liquid Nitrogen Dewar :)

Basically, all you have to do is pour some LN2 in a thin metal cup, and the LOX will actually condense on the sides of the cup, and drops of LOX will quickly drip into a test tube that I have partially submerged in another cup of LN2.

[elmasshop]

cool :D

[thisissparta1066]

The guy talking is Richard Hammond who also presents Top Gear.

Basically this show is an excuse to blow things up and do all the science experiments that are banned in schools in the UK now (such as the sugar monster experiment).

There's a few others in the series such as answering if you can stand on custard..

[tannersword1]

what are you talking about? it's simply an oxidizer

[tannersword1]

these guys are good at making people stupid. liquid oxygen isn't a fuel... it's a strong oxidizer

[liquidoxygen0]

tannersword1: Actually it's both. But to my knowledge it's only ever used in spacecrafts as fuel. I don't know about aircrafts, but I've a feeling some models use liquefied Oxygen or Hydrogen.

[JoeytheHDK]

DINNER'S READY!

[Deathbringer135]

lol

[killertofu101001]

YOWWZEERRRZ!

[Draxis32]

Interesting, do not try this at home, but uuh.....who does have liquid oxygen in home?

God you're a dumbfuck.

[furiousharry]

it was a joke.. cant u see?

[Draxis32]

It was a bad joke my man, he even repeats it...

Wich turns it even worst

[furiousharry]

lol dw its english humor, only the english understand understatement humor lol

[Draxis32]

:D

Then I'm sorry, well i made a joke myself, i didn't mean to be evil on those profanity words.

[thedude77777]

oxygen does ignite

[XSFx5]

Ignorant YouTube idiots... *sigh* No, thedude77777, it really doesn't. It's an oxidizer, not a fuel. Futhermore, the ignition is from the microwave magnetron heating up the steel wool until it melts or vaporizes as sparks. Adding more oxygen simply enriches the oxidizer's concentration and thus allows the rate of the reaction to violently accelerate with a positive feedback loop from the heat, until creates a pressurized fireball. Still badass regardless.

[thedude77777]

i meant to write "doesnt"

[doceigen]

The really cool demonstration, sure make you appear very sexy in front of a party of hotties, is to breath in a whole lungful of pure oxygen and then light yourself a cigarette! They are gonna love you!... what's left of you anywise...

[dmbfan1912]

Oh yeah, everybody is gonna run home and put some liquid oxygen in teh microwave, because we all have liquid oxygen just laying around. Oh sure, we could all make liquid oxygen, but then again who the hell has liquid hydrogen just laying around? LOLX7+42

[itsumonihon]

all you need to make liquid oxygen is a compressor, in fact it's conceivable that some people have accidentally made liquid oxygen by using their compressors improperly. it's less likely that someone has been injured as a result of a lox leak or explosion but it's possible

[dmbfan1912]

You'll need to cite references.

[itsumonihon]

just search youtube for it! it's the same way lox is made on an industrial scale, they just do it bigger

[dmbfan1912]

No, you'll need to find references where it is documented that people have accidentally produced liquid oxygen using compressors. Have you ever produced liquid oxygen? Do you know what you are talking about? You'd need to cite references to your own education or background with supercooled liquids. Furthermore, anyone attempting to purchase liquid nitrogen will be highly scrutinized to the point where the truly inept are weeded out.

[dmbfan1912]

My point was that anyone who actually is in possession of liquid oxygen would probably be of sound mind enough to take proper precautions with it, and if such a stunt was attempted, proper precautions would probably be taken. No one capable of possessing LOX would jeopardize house and home repeating something on youtube.

[itsumonihon]

i said it's CONCEIVABLE that people have done it by accident. it's also CONCEIVABLE that nuclear fission has occurred in nature on earth, while finding citations for it might be difficult or impossible.

[dmbfan1912]

It's conceivable that you missed my point twice. While I can't point to references showing that you didn't understand, (Only you will be able to know whether you truly understood me) I can say that it is highly conceivable that you didn't get it. Also, the critical temp of oxygen is -113, so no amount of pressure after that tempurature will liquify it. and let's say, for the sake of arguement that you had that temperature. You would need a pressure of 734 psi to liquify it.

[dmbfan1912]

and let's say that you had a normal household air compressor... most of those units have a normal operating pressure of 90 psi, with a maximum pressure between 135-150 psi. So, you would need a specialized industrial compressor used for filling high pressure tanks such as scuba tanks. Those compressors are capable of supporting pressures upward of 3500 psi. However, obtaining one of those compressors is not something a 15 year old kid would be able to do. So... let's be reasonable.

[dmbfan1912]

Besides, if someone were inclined to do something incredibly stupid, they wouldn't have to go through all this trouble. A trip to a garden supply center, fireworks store, and a gas station with $50 can produce results on a cataclysmic scale. However, the point being that it is highly unlikely you find someone capable of repeating this.

[itsumonihon]

you missed the point, any home compressor can compress enough to have the gas cool to a liquid if it passes through anything resembling a condenser. it's theoretically possible that someone has accidentally created a condenser unit while intending to use it for some other purpose. youtube it there are several people making LOX with compressors and a few of them are using it for amateur rocketry.

[dmbfan1912]

You'd need to cite references for this. I searched and found nothing to back your claim. Home air compressors don't carry the necessary pressure required. The only way to do this would be to plumb the compressed air back into the compressors inlet after it has exited through a type of expansion valve which would cool the air, Then, the air would have to be cooled again, repeating this process until a temperature colder than -300 is reached. It's not something that could happen accidentally.

[itsumonihon]

allatomsDAWTcom/LOXpageDAWThtm shows how to do it with a scuba cylinder of compressed oxygen, anyone with a scuba grade compressor could do it just like that page, and it's entirely possible that a home compressor could do the same thing.

[dmbfan1912]

That's what I am talking about. You see, I mentioned that the pressure needed is above 700 psi, and could only be obtained by a specialized compressor specifically capable of high pressures. I specifically referenced scuba gear in my explaination of how this couldn't be done with a home compressor which is only capable of 10% of the needed pressure. I specifically mentioned this. I gave you many chances to redeem yourself. You have proved nothing, and therefore have lost my respect. FAIL

[Sirob972]

i will try this at my friend house xD then run away

[ImtheTroubleIn421]

you can make O(l) yourself, the complicated part is getting the N(l) an the purified O(g)

[howe094]

these guys don't know shit about science.

oxygen doesn't ignite, it increases the rate of the burning of the steel wool

[rszemeti]

agreed, and the "oxygen is highly volatile" comment just shows they haven't quite understood what oxygen is/does

[XSFx5]

Yep, but then again I'll bet none of the script writers are chemists. The bad part of this is this is how myths that are totally false get started.

[SaltiestPeach]

@howe094 Liquid Oxygen is a highly reactive/combustible material. The STEEL WOOL is actually the igniter for the oxygen.

[howe094]

@SaltiestPeach Oxygen does NOT burn, it just allows other things to burn, oxygen itself does not combust or ignite, I can't believe so many people don't know that

[creamyfilling102]

is that the guy from Top Gear?

[abhiginimav]

yes, hammond

[thriller920]

man show

[tomek123kotek]

I just watched this yesterday

on tv...

[verwer777]

cars are better

[HowlingStone]

lol, fuck that. liquid oxygen is no joke. i work around cryogenic liquids for a living and i'll fuck around with nitrogen all day, but i leave the oxygen well alone.

[thejava1]

I like all these microwave experiments, primarily because they talk about safety. Yet i find it intriguing that none of these people have heard of a "switch" you dont have to turn on the microwave and run away. you can turn it on from a safe distance. You coud even plug/unplug the microwave ooo!!!

[BHT195]

Liquid oxygen is not used as rocket fuel, it used, rather unsurprisingly, as the oxidizer. Since there is no oxygen in space its needed to be carried onboard so the fuel can burn and provide thrust. Now to cancel out the seriousness of the preceding; boingo boingo whoopsey knickers.

[faxmanloveswaffles]

@BHT195 the nitrogen is the actual gas the fuels the rockets. even though purely nitrogen can't burn because it need oxygen.

I finished you answer!

[4O4ERR0Rrs]

@BHT195 it and liquid nitrogen are..... that's what is in the big red tank in front of the space shuttle, please research before putting dumb things onto the internet

[lasergeak]

thats not exploding oxygen

it would'nt burn with black smoke

[Casowsky]

Good point...

[RockyMHorse]

I love this show! ^^

[MissileSlLO]

i want to try this at home. where can i get liquid oxygen?

[iissmm3]

get a license for using it making sure your not some kid who does not realize you can put this stuff onto your hand for 3 seconds and hitting it softly will shatter it into a million pieces. make sure your over 21 and last buy the equipment required which after all set and done the gloves, mask, storing device. it all costs 400 dollars in total and LAST the stuff cost about 40 dollars an ounce.

other than that go to the store and show them your license and buy it.

also its no toy so dont play.

[MissileSlLO]

thanks, didn't know you needed a license to get this.

[Ormaaj]

you don't need a license to get liquid oxygen as far as I know. Its quite easy to synthesize small amounts of it on your own with dry ice or liquid nitrogen, condensing it from air while the nitrogen evaporates. I suppose you could also get oxygen by itself from electrolysis or hydrogen peroxide plus a catalyst.

[notabook]

God you're a dumbfuck.

[shifforbrainz]

i love brainic

[crazyhugs]

is that the guy from top gear ? , wat show is this ?

[taffel105]

yes it's that guy from top gear... and the name of the show is braniac

[clerlic]

I'm gonna try this at home!

[666Bandaged]

good show!

[000Mbarry000]

Is that Richard Hammond?

[evan1005]

Wow. A few errors in the narration. First, liquid oxygen isn't used as a rocket fuel; it's used as an oxidizer of the rocket fuel. Also, liquid oxygen cannot ignite, since it's not flammable; rather it makes the steel wool burn faster. Due to the incorrect terminology used in this video, it assumes a lack of understanding in the general audience.

[moonspots01]

I caught that too. Keep this in mind and in context; shows like this have NO educational value AT ALL! They are geared for the easily amused and dim-witted. (Yes, I realize that I have watched it as well.)

[dlk2528]

...and the oxygen ignites... WRONG!

[pommyrooter]

actually it is true becoz it is LIQUID and oxygen is wot burns idiot

[dlk2528]

ok, i dont know why i am dignifying you with a response due to the intrinsic illness of your response. must be something in the water at "ya mums belly, ya mum ate it", australia. anyway, oxygen, does not burn technically much like gasoline doesn't burn either. it is the vapor of the fuel (i.e. the gasoline) which burns and the oxygen is what supports this chemical reaction(oxidation) because fire is simply a material oxidizing and giving off heat and light. wot now, idiot?

[frizspin175]

They don't know what they're talking about. Liquid oxygen doesn't ignite.

[Disfik]

my friend found a hamster on his deck, so he put it in the microwave, and he said it exploded.

[NicksJoesKevinsLover]

I wonder if someone tried that in their house.

[SamuriCam]

Ooh, Brainiac!!! I love Brainiac...it's ALMOST cooler than Mythbusters...

[Josh906]

Brainiac is awsome!... but Mythbusters is better! and i never see brainiac on tv :'(

[sethtastic89]

except the mythbusters crew know what they're talking about and explain everything they're doing.

[teamhex]

Yeah thats true, but there methods are stupid sometimes. They either spend to much time on something already proved or common sense. Or they fuck up and don't do something right. For instance. ydEkV-E0mP8

[renegadeoflife87]

That is true, however this video is clearly misnarrated. Oxygen itself cannot possibly burn- however it can rapidly accelerate the combustion of other substances.

In this case, the steel wool is ignited by the microwave like before, but the oxygen causes it to burn much more intensely and the heat boils off additional oxygen.

Eventually this ignites the inside of the microwave, and you have your explosion as it flashes into heat.

[MaxMouseDLL]

Everything can burn, including Oxygen, Inside stars for example.

Also this shows like this aren't stupid etc, they are just no brain entertainment, something you watch and laugh at :)

[frizspin175]

you can ionize oxygen but it won't burn

[YYYYYYYYYYZZZZZZZZZZ]

I think these guys "enhance" their experiments. Like, look at their propane thermite experiment and then look at mine.

You will see what I mean. Mine is not fake.

[godmode911]

omg! who would have thought putting rocket fuel in a microwave would cause an explosion! Twits.

[AryanBlitzkrieg]

It is used in Rocket fuel it is NOT rocket fuel...

Twit

[godmode911]

same shit, idiot.. go suck a dick.

[LunaticCalm]

He's saying LOX is used IN rocket fuel, but not on its own. It's an oxidizer used with other materials (such as Kerosene).

[poptya]

lol Hamster shows up everywhere.

[wiinsider]

WTF!!! I need a new microwave and these guys are just burning one!

[SeanPhone]

that's stupid

[liquidoxygen0]

I imagine it would cost them a hell of a lot of money in the long run. Guess they get some kind of government or third-party funding?
