is that wool the scientist's hair???

[jorge10928]

the bald guy never talks?

[mecrazy5]

@jorge10928

Is that a question or an observation?

Because science isn't for girls.

[ih8gamer]

i thought ozone molecules had four oxygen molecules

[ih8gamer]

I thought ozone molecules had four oxygen molecules

[ih8gamer]

i thought ozone molecules had 4 oxygrn atoms

[therandomexample]

aww..this makes me not like America too much, because I never learned this, although I haven't finished school yet. These videos are truly lovely, though. Much more education in a short time span than I've had.

[talshiarr]

@therandomexample Blame the atrocious state of science education in this country. Too many touchy feely social classes have become priorities for politically correct administrators.

[9hello123]

@therandomexample You didn't learn that oxygen is needed for fire?

[therandomexample]

@9hello123 Oh well I of course learned that. They just really only give very basic things.

[paopaomanalansan]

Will the splinter light after it has lost its red glow?

[shunnehling]

@paopaomanalansan no it wont light because the splint is no longer going through combustion. it has to still have its red glow.

[Flatine1]

hahah that guy talking about the oxigen looks like those old movie mad scientist xD

[carlosewm]

Psychotic laugh at 2:25 lol

[Slic3R1]

if you heat a diamond to when it becomes red and put it in liquid Oxygen it will completely dissolve

[9hello123]

@Slic3R1 no it won't lol.

[Slic3R1]

@9hello123 well i didn't mean to say dissolve i meant to say that the liquid oxygen will speed up the oxidation process of the diamond so that there will be nothing else left

[9hello123]

@Slic3R1diamond doesn't oxidise in cold temperatures. which liquid oxygen is, it would start oxidising when you heated it up (very little considering how stable diamond is) and then would completely stop when you added liquid oxygen to it.

[Slic3R1]

@9hello123 ill send you a link to a video as soon as i find it

[JoshuaRapana]

The guy with the affro is classic

[jellykelly696]

I'd like to know where do the get Oxygen from. I know we breath it in the air, but it's not pure oxygen..it's mixed other elements like nitrogen and other elements. What I'm asking here is how and where do they get from so it can be used for filling gas cylinders used for welding and stuff. Do thet get oxygen in gas form by vaporizing Liquid O2.. Does anyone know??

[sharinganx12]

Pure Oxygen is formed later in a stars life in the outer Helium shell. About 0.9% of the sun's mass is Oxygen. At normal atmospheric pressures Oxygen is in the form of O2. At very high pressures an extra oxygen atom bonds with O2 to become Ozone, which has highly oxidizing properties. However we can't breathe pure Oxygen since it's dangerous alone...

[squalea]

Liquid oxygen is the same thing as gaseous oxygen, it's just very very cold so the gas condenses into a liquid. If liquid oxygen is raised to room temperature, it would expand and become gaseous oxygen.

There are several ways you can get pure oxygen... Look up a process called "electrolysis of water" and you'll see that you can separate water into pure hydrogen and oxygen gases by just running an electric current through it.

[kriegkatse]

oxygen gas is made cryogenically to separate it from the atmosphere. The product is liquid oxygen but if you want it in gas form there are some fairly safe procedures the industry uses for making it a gas again and storing it. But as far you making it yourself in a highly pure form i would suggest don't, its far to flammable, you are better off buying it.

[Clarisserj]

aparenta ser um video muito bom, pena q nao entendi nada o q estar dizendo, I do not speak ANGUAGES. bjs

[Agentoxedo07]

holy-terrorist:>, yes, is this compression air, = nitrogen oxygen, and is nitrogen degrade and recolted oxygen *=* thank

[DeltaPhi79]

Nitrogen oxygen? I'm not sure, but don't you mean nitrogen oxide?

[waybeforetheplatypus]

Neal is badass

the Profesor too

[HaydenPK]

probably spelt neil- but you're right i don't know how it's spelt

[Tropps82]

It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.

[Tropps82]

The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.

However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions.

[o0tinerz0o]

yup its the hydroxyl strech of the oxygen, also why water is blue the oxygen (actually the hydroxyl (OH) stretch causes light to blueshift

[sharinganx12]

Hey why are there thumbs down on my comment? Anyways think about it. Every living thing, every matter in the universe is at least made of a hydrogen atom or started as a hydrogen atom. Living things need oxygen to breathe. 2 Hydrogen atoms bound to an Oxygen atom, water. Yep, water is the essence of life and every living thing were made of water. I also guess that's where fishes get their oxygen (from water)...

[powermousey]

Every living thing physical and every fragment of matter and energy is made up of empty space. Not empty in the sense that nothing is there but of negilible mass...sorta like a foam mattress. A background substrate network of various particles and waves. Signals at various states and frequencies and of vector forces of attractions, repulsions, and nuetrality and involving other bodies,and of 4d space time.

[yelton7]

so that is why the sky is blue

[Brucey117]

Not really, no

[tori94]

awsome dude

[Prince4999]

why the hell the guy starts to laugh????

[cutebuttt]

cos he's a frustrated professor, - needs to be careful, with all that volatile stuff around him , don't you think?

[Ormaaj]

If ozone is more reactive than oxygen, it makes a better oxidizer right? If this is the case and you liquefied it, would it not make a more efficient oxidizer for rockets? Less weight = more lifting power.

[zokyle]

Good point. Never thought of that really.

[andrewapotheosis]

you guys should so an experiment demonstrating oxygens paramagnetism!

[Ducky1138]

This is my favorite video by them, i just love the color of liquid oxygen, it's like looking at the sky, but in a beaker....

[keitaidenwaKern]

if ozone is heavier than oxygen then why is it in the ozone layer above us. Why doesn't it come down.

[tomandjj]

first of all gases don't tend to arrange themselves according to density because their is a lot fo wind and such. for example nitrogen is lighter than oxygen slightly but both are mixed in the same atmosphere. secondly ozone decomposes within about half an hour at lower altitudes what tends to happen is as it sinks into our atmosphere it decomposes and oxygen from our atmosphere can also go up and be converted to ozone. you can smell small amounts of ozone after lightning storms.

[awol09]

or you can smell it after being around a jacobs ladder

[Ducky1138]

I suppose tomandjj could be correct as well, but im pretty sure since ozone absorbs uv-light it's molecules become more energetic, thus less dense than oxygen, so it rises...

[gabi83tm]

"So, near the Earth's surface, where you and I are at the moment..." lol

[JeffreyRodriguez]

Flame on?

[Nygle123]

he said bum! HAHAHAHAHA

[kandastrike]

these guys are awesome!

[inglebert123]

the hair of england :)

[Kaarel314]

Its so stupid in movies when people burn oxygen.

What do they think happen? O2 + O2 ?

[TomMarAlem1987]

They put in a wad of cotton. Cotton is a hydrocarbon. Hydrocardon+O2= CO2+H2O.

[Kaarel314]

I know that, i meant cheap hollywood movies.

They tend to burn oxygen there.

[ktmggg]

"They tend to detonate and cause very enegetic experiments."

"If not dead, certainly much less comfortable than we are at the moment."

I love droll British understatement.

[frizspin175]

please do a demonstration of paramagnetism of liquid oxygen.

[motorbyclist]

whatever happened to that hole in the ozone layer? middle of summer down here in NZ means ten minutes to sunburn on a cloudy day, that's what.

[roendm]

this are crazy scientists hehehehe,

[limlynn999]

the angle of video camera sometimes looks too bright

[Sectorsophia]

I love these vids. I'm learning a lot more about the elements from these videos than I am learning in my college chemistry class.

[noeatingallowed]

That sit-down fellow needs an afro pick. Bad.

[dlacc187]

lol

[hellknightlizz]

These videos are brilliant- I often sit and stare at the PT in my A level chemistry class and wonder what on earth there all like!

[Thedutchjelle]

Nice vid, but the audio recording kind of hurts my ears ;(

[evansp12]

Excellent demostration. Very well presented video. Thanks for posting it.

[JTC2films]

nice to see these guys made something of their lives than slumping through high school and doing drugs and drinking. all the "Cool Kids" are fat in a trailer now.

[Paxmax]

LOX is also cool... escpecially in combo with charcoal!

Light your barbecue in 5 secs flat!

[Jonusmax]

You know, for years I have walked around with several theorys of why the sky is blue, but this one finely explaned it to me, thank you!

[pairmaster5000]

but the atmosphere is only 21% oxygen.

[tapirus1]

You know, this has nothing to do with why the sky is blue. Just google for "why is the sky blue" to find the real reason.

[genarox1995]

u can buy pure oxygen, and they have it flavored

its $10 , i wanna get some lol

[DuskY1991]

Cool experiments. I have never seen the 'relight the wood' experiment before. Not even inschool as far as i can remember.

[vmelkon]

I've read that liquid ozone is a dark violet color.

[daniboy1995]

can u breathe pure oxygen (100%)

[docskin]

Yes, but not for extended periods of time as it damages your lungs.

[sums2006]

which is also why scuba diving tanks are compressed with normal air, instead of pure oxygen

[Paxmax]

It all depends on what kind of diver you are.

Some ppl have more sophisticated equipment and DO bring pure oxygen in their tanks.

They "scrub" the air from CO2 and just add new oxygen (or a oxygen/nitrogen/helium mixes)

Remember, SCUBA just means "self Contained Underwater Breathing Apparatus". It does not specify that you breath compressed air.

[morphine285point4]

You can for a while, but if you do it for too long it will start to have a toxic effect and will eventully kill you.

[CharlieBBoy12345]

Is all burning oxidation?

[maekern]

I believe so, yes.

[yhaqtera]

Oxygen haiku:

Green plants' waste

Earth's invisible treasure

Now breathe!

[atomic7732]

3, 7, 2 THAT's NOT A HAIKU!

[yhaqtera]

Sorry, I didn't write it. I read it somewhere on the Internet a while back and I remembered it as I was watching the video. I'm no haiku-purist, so the 3-7-3-rule never occurred to me.

[atomic7732]

Actually it's 5-7-5.

[bacardi122]

hgahah.....babys bums...this channels great!

[PenguinBoy92]

those guys love explosions

[XxDEBUGxX]

I think they do that to make it more appealing to a younger audience, sadly in most cases that's the only way to make them sit through a scientific program. :-\

[maekern]

Though even to an older audience member such as myself, who even watched the Ununpentium and Ununoctium videos with interest... the explosions are still cool. :)

[THEspindoctor84]

explosions... are awesome! why complain>

[Festerius2008]

It is one of the many reasons that the sky is blue, despite what primary education teaches people, the sky is blue due to a combination of factors, one of them the fact that it contains oxygen. O2 is visible in gigantic volumes.

[whyizat]

First comment! Woo!

[Festerius2008]

Congratulations! Here is your prize! (It is a stale crisp...)

[whyizat]

Amazing. :) I love it.

[0Linerider0forever0]

Well that was certainly random.
