Hydrogen - Periodic Table of Videos

[wallis34]

Nice....stick some oxygen in the balloon with the hydrogen next time, you get a much louder bang.

[2cdd7]

ACME on detonator :))))))))))))))))))

[UltraDrago2000]

the person walking back bekind those trees was probably scared shitless

[oicub2]

Color comes from excited atmospheric gases =-) LOL =-) 4:05

[Nevir]

So, if the tenis ball prop is actually the size of a small volleyball, and the professor sets the ball next to his mug, and the ball is just a little bigger than the mug, is that mug holding a whole pot of coffee?

[OOZ662]

@Nevir The mug is at the front of the desk and the ball is set toward the back. He drinks from that cup in one of the alcohol related episodes, and it's your average size coffee mug.

[gemis94]

The interlacing on the video looks quite bad with things moving.

[GTHaroFITBMX]

0:43 that be one BIG tennis ball!

[Dennis060796]

I feel...much smarter.

[ps3spoiler]

What is cold fusion?

[Hoshimaru57]

"No, fusion reactors are way beyond what Pete can do, unless he's much cleverer than I think"

Pete- " I (looses balloon) have-had, a balloon of hydrogen..."

Well, I guess we can say that Pete's one of the denser elements in that periodic table...

[microbemania000]

There is a guy in the forest in y

[microbemania000]

There is the forest in the background

[NarlepoaxIII]

VSauce?

[MrJonathandowns]

The red flame color is most likely caused not by the balloon burning, but the powdery substance that forms a very fine layer on the balloon. Of course, I'm guessing based on balloons I've handled. I'm sure spectral analysis would be a way of finding out what made the nice color, and likely it'd mostly find carbon of course.

[MrSmudger687]

@MrJonathandowns - It does actually make a nice red colour.

[Vimeslgospare]

@MrJonathandowns It's most likely corn starch.

[zajac88]

this idiot is pretending he is einstein

[NarlepoaxIII]

@zajac88

No, he's just got a white jew-fro.

[MrSmudger687]

@zajac88 - Says you - someone who favourited a video that claims nasa are covering up signs of alien life on mars. This man is a world renowned professor of chemistry, you on the other hand, are nothing.

[pooppeeyoupants]

@ispravljat i know ur curious... but hydrogen is stable, thus it does not have a half-life, unless what ur saying is the isotope H3, then 17 yrs i do believe, but pure hydrogen has no halflife, thus it could live forever!!! Halflife's opposite would be stability.

[QuantumDisciple7]

@pooppeeyoupants

Not necessarily. A proton has a half-life associated with it, if you believe GUT Theories. This half-life is an unimaginably long time, possibly even longer than the existence of the universe. However, eventually one of the up quarks in the proton will decay into a down quark creating a neutron. This will then cause the electron to not by attracted to the nucleus and the Hydrogen atom will no longer be Hydrogen and break apart as subatomic particles. I Think.

[tnguyen318]

H2O. LOL.

[assasinfreak12]

hahaha i love how crazy hair guy says he doesnt know where the color comes from then all of a suden goes into full detail about how it happend

[WoodzTV]

very punny, first sentence is "we are braving the elements" ;P

[J0LaPi]

I just saw a news article about tritium leaks found at 3/4 of the US commercial nuclear power sites. Oddly enough, my first reaction was excitement that I knew tritium is a radioactive isotope of hydrogen (from watching this video.)

[boiledhooker]

I could listen to the professor lecture all day.

[angryDAnerd]

Leave the balloons aloneeeeeeeeeeee

[theyolkwebshow]

professor,...... (I don't know your name I'm sorry) the reason the hydrogen burns a red color is because of the emission spectrum. but, it also might be turned more red by the carbons in the latex balloon like you said.

[oomblikkies]

@theyolkwebshow I suspect there is a slight excess hydrogen and its this hydrogen that gets heated up by the reaction and the red color is the atomic emission color for hydrogen

[runnybabbit12]

ok i use stand your need to explain the experiments scientifically but some of this can be pretty complicated

like "match-on-a-stick"

can you guys please but that in lay man's terms?

[MrRetardedSuperman1]

lol there was a guy walking in the background hahahh

[Hazzrine]

At 2:17 does anyone else hear "Is a gay..."?...No?...Ok then.

[geckoguy798]

@Hazzrine OMG WTFH

[KiraandHarre]

@Hazzrine `is again' egg head.

[pmhorler]

Mad PROFESSORS,just brilliant !

[aardvark9100]

I have derived hydrogen from water by electrolysis and lit it which produced an orange-red flame when lit with air. Hydrogen bombs detonated as air-bursts have a hue very similar so maybe the color is from an atmospheric phenomenon since under lab conditions it is colorless while burning.

[Me102288]

@aardvark9100 I believe its based on what a hydrogen flame is touching. /being the flame burns at 100 degrees touching "air" and hotter the the surface of the sun when touching something like tungsten. could it be the gas's around it?

[WeaslyTwins]

2:25

HAHAHA LOOK AT HIS HAIR, ITS AWSUUUM <3

[bikr1975]

hahahahaha wow....you can make it far louder than that. im getting my fuel from my 10lpm hho dry cell and fill a large balloon that already has a waterproof green fireworks wick inside and after i fill the balloon with hho, i wrap enough scotch tape around the openeing and the wick tightly to make a seal. the wick should be long enough so it wont weigh the balloon down. mine was 10" long and floated up about 200 - 300' then detonated. the bang was deafening. try that. entertain us.

[Me102288]

@bikr1975 why would we want to deafen ourself?? Lol get the police to your house fast doing that in this area :-)

[Twostones00]

I can dig it man.

[FabledTitan]

Very nice. Subscribed!

[LsBaba]

Love the Prof's hair :)

Spookily, he reminds me of Jo Brand in the close ups. Perhaps he'd make a good host for Have I Got news For You.

[ZombeTheImmortal]

I thought ACME makes microphones, headphones and CDs, not detonators? -.-"

[NatureWasFirst]

@ZombeTheImmortal ACME Corp' also manufacture the following: Dehydrated Boulders Bat-Man Outfit Rocket Sled Jet Powered Roller Skates Earthquake Pills Catapults Portable holes Burmese tiger trap kit Super leg vitamin Anvil Mainly geared to kill Road Runners but still effective in other areas.

[tanyc1173]

Even you CUP has a print of the Periodic Table. Cool!

[yittymitty11]

look at 3:11 the guy walking in the background pauses when he hears the bang

[MrCubfan415]

2:01 What about the Hindenburg?

[WeatherManToBe]

I'd let pete do many things to me

[7222Brit]

oh how i love your dog toy atoms professor

[DeFliegendeHollander]

"ACME detonator" (written on the detonator) : rotfl !

[dahduke]

Hydrogen without oxygen will give you a blue flame hydrogen with oxygen gives you a yellow / orange flame the color will change depending on the ratio of hydrogen and oxygen i just did a test on my car and these are the results Hydrogen in my 93 Camry gets 13.77 MPG increase

my 93 Toyota Camry without Hydrogen, I went 37.3 miles on 1.058 gas = 35.25 MPG/adding Hydrogen, I went 68.3 miles on 1.392gal = 49.02 MPG giving a total of 13.77 MPG increase

[dzgfdg]

@dahduke haha are you mental? Hydrogen without Oxygen will give you nothing, Hydrogen with Oxygen will give you the blue flame. The yellow flame only occurs if your fuel is contaminated with some other gas like chlorine

[iAREchrisC]

anyone else notice the guy behind the trees that stops when the balloon explodes?

[jorge10928]

@iAREchrisC It's Sasquach.

[tribalwolfify]

@iAREchrisC i noticed :)

[rolandas1985]

How about Deuterium and Tritium nuclear reaction?

[87divinesoul]

Does anybody know the name of the professor?? Would appreciate if someone could reply me

[Adrenalinism]

@87divinesoul poliakoff.

[sabaths1fan]

@87divinesoul Prof. M. Poliakoff. Went and looked it up just for you ;D from the chocolates and roses video.

[emmazedutchoven]

9 simpletons disliked this, I wish I knew a person like this because Im always asking questions like that, but my professor never answers me.

[BarneySaysHi]

The person in the background reacted like "What the hell did I just hear?"

[keyloggersfiles]

lol, he's using a dog toy to represent a hydrogen atom

[ERFireworks]

@keyloggersfiles actually its not a dog toy, its a dildo

[sabaths1fan]

@keyloggersfiles Many of his atomic and molecular models are dog toys. In fact, they have a couple videos about it.

[Radl0activE]

You guys scared that random person walking by.

[flabazoid]

acme detonator? who thought of that one?

[MapleOryDude]

the reaction is awesome ! with boom!

[randomvideowatcher]

"braving the elements" LOL

[QcTechs]

The fireball is composed of water plasma.

The reaction is so hot that it converts its product (H2O) from gas to plasma, which emits photons of a redish wavelenght

[Babaji367]

@rob27222712: yes, electrolysis of D2O will provide elemental Deuterium, and yes, that could be fused in a reactor to form Helium, which would indeed provide you with lots and lots of clean energy. But don´t be fooled, such a fusion reaction would require a vast amount of energy to start, which is why in hydrogen bombs they use a normal atomic charge as the source for the energy. If a "cold fusion" in a reactor ever worked though, it would sove the energy crisis easily,

[wwefan70511]

sWEET hAIR :p

[rob27222712]

so when you perform electrolysis on water you get H2 and O2, my question it when you perform electrolysis on deuterium oxide (heavy water) when it splits into D2 and O2, and would the D2 gas make helium in the reaction the professor talked about? and would it create a sufficient amount of energy?

[cristianfcao]

Hydrogen can do much more interesting things that exploding balloons. One of the most memorable clips in the Cosmos series (Ch. 13, I think) covered basically the history of everything: the beginning of the universe, the formation of stars and planets, the evolution of life and even the history of mankind since it's dawn in Africa to the space program. At the end of the clip Sagan says: "These are some of the things that hydrogen atoms do, given 14 billion years of cosmic evolution". Respect H!

[derickhaywood]

ouch he forgot to mention the hindenburg thats embarrassing.

[Pirate88179]

Excellent video, thank you.

Bill

[alex49carson]

theres a guy walkin behind the balloon

[johnm7115]

They should do it again with a balloon filled with hydrogen AND oxygen, maybe use an even bigger balloon as well.

[75TRIPAS]

do farts have hydrogen??? Hmmmm?....

[Juxtaroberto]

@75TRIPAS They have hydrogen sulfide...

[evgenpower]

@75TRIPAS Im not sure, but I think its methane gas, not hydrogen

[artismylife92]

@evgenpower Methane gas is a hydrocarbon with the formula CH4, so yes, it contains 4 hydrogen atoms and one atom of carbon

[flexyco]

Nice video!

But, why not emphasize the most important ongoing event in our universe, the fusion of hydrogen into helium inside the core of every (main sequence) star and the fact that this fusion created and creates most building blocks known to man through nucleosynthesis. Almost all matter heavier than hydrogen is the result of dying stars that went supernova, ejecting particles into every direction. That would've been worth mentioning instead of the H-bomb.

[dunnobutwayne]

ACME detonator :D

[TeenageIronman]

@dunnobutwayne What are you talking about?

[alexzhang101]

i like your cup and your hair

[sfuk89]

How hot is it getting?

[Zakumi095]

3:11 my favorite , Lovely :X

[ditryzy]

por favor que lo traduscan. Estos video son muy interesante.

[homousios]

thank you

[Ben79k]

I learn so much from every one of your videos. I wish you were my teacher in school :)

[EPICGUYDUDE]

just curious, how do they get the cold temperatures to get liquid hydrogen? and how did they get it that cold?

[seijurohiko168]

He's right! the fusion of deuterium and tritium creates an enormous amount of heat and the reaction can only be contained suspended in space (done on earth by spherical flux magnetic fields). you can imagine the reaction similar to the scene in the spiderman 1 movie where dr. octopus tried to make a small sun. :) ... amazing stuff.

[imrbyamile]

The orange color of combustion could also be caused by the powder that is lining the interior of the baloon to prevent it from sticking together before inflation. Just a thought as I have produced HHO and burned it, it makes for a nearly invisable flame.

[1993gandy]

i was hoping for a weather balloon :( oh well lol they are quite expensive

[kingspunkbubble]

funny that he says he' outside braving the elements.

[Vennificus]

Ha, Acme detonator. Might want to check your supplier Wile E.

[sherkin735]

lol at the guy in the background at 3:09 he just like freezes on the path. i bet he was like wtf was that hahahahaha

[jakazza]

move over einsenstein

[themine691]

am i the only one that thinks that the coffe cup ever on his desk

[onceigoblack]

i will show u what is bigger than what u have ever seen or felt

[nasalflute]

He let's two explosive balloons loose in the building that hit the ceiling.

Dumb d dumb dumb for such smart peeps.

[imrbyamile]

@nasalflute I know somone who filled a balloon with oxygen and accetaline from a torch set and when he went to set it in the grass a static discharge detonated it. He was not severely hurt but lost some hair and eye lashes over it.

[nasalflute]

@imrbyamile Pretty lucky dude. This stuff may seem fun until they visit the burn ward at their local hospital. Then they ask themselves "was it worth it?" Fire and such is fascinating but not as fascinating as skin falling off and scars from it. The way someone may look after burned will hopefully make someone think twice. Not just the look but the pain and possible loss of life.

This could be far worse than a burn to the skin.. what if a building caught fire and other occupants killed?

peace

[calito0010]

3:53 dude has my hair!!!!!!

[laharal90]

The hydrogen bomb he is talking about uses two different isotope of hydrogen. Tritium(2 Neutrons and 1 Proton) and Deuterium(1 Neutron and Protons as he said)

surrounded by high explosives that compress the masses, therefor lowering the required heat to create a Plasma ball that acts like a nuclear bomb (air and heat blasts rising air falling debris) The reaction creates helium and releases a neutron. Also plasma reactors are current impossible because we can not generate the heat required.

[jbriga123]

I thought 2H2 + O2 -> 2H20 is an implosion, not an explosion -_- you get from this reaction actually 18mL water :)

[uut0]

i once made hydrogen by accident by dropping a buttoncell battery in water :O.

[maxasampson]

anyone heard of sulfur hexafluroide, its a dense gas, basically the opposite to helium, makes your voice sound deep, its a very cool thing, go check it out

[AHW214]

2H2+O2=2H2O

[ZenonDorinPower]

i wish they had done a small nuclear explosion with deuterium

[imaball]

should have done it at night =D would have look sweeter

[sciencefreeak]

i want to become a chemist to but another thing to watch on youtube is nerd rage

[busterlanger]

Are you going to update any more videos?? I only want to know because I love chemistry and want to become a chemist and these videos are really interesting and fun!!!!!

[BlackRaptor31]

It would of been funny if they accidentally let go of the balloon at 0:55

[chumchumthegreat]

Good lord, an actual ACME detonator

[HappyFatzKid]

Anyone else see the guy walking in background when the balloon goes off?? He just stops. I laughed for a but watching that.

[tommatdan]

yer i know lol

looks like they didn't see him/her though

[Robotehrobot323ALT]

Happy 100,000 views

[Afrocanuk]

Would anyone know another substance besides water that expands and becomes less dense upon freezing and floats in its own liquified state?

[jedi1357]

Antimony, Bismuth, Gallium, Germanium,

Acetic Acid ( CH3COOH) and  Silicon.

[ginomw]

does fire have a kind of molecule?

or something like a molecule?

and witch one.

[otleybey]

Fire doesn't have any one particular molecule. It depends on what it is you are burning. The flame is a mixture of hot particles, the result of oxidation and various side reactions, that emit visible light. Different particles can give flames different colours - try chucking table salt on your gas hob, it will be yellowy. Calcium salts make the flame go red.

It's like the guy said - the red colour of the burning hydrogen balloon was probably from the balloon itself.

[chsxtian]

no that's the color of burning hydrogen. a bit orange-red

[JoonasD6]

No, fire is not substance. Fire itself is light which is energy released because of a chemical reaction.

[jedi1357]

Interesting you should ask. Try looking up "Phlogiston theory". From 1667 to 1753 it was an accepted theory in science/alchemy.

[tommatdan]

hydrogen forms an H2 nolecule - 2 atoms of hydrogen covalently bonded together

[Drag0nfoxx]

@ginomw - No it doesn't. Fire is a reaction of a substance and oxygen. There are some interesting theories from a few centuries ago about 'phlogiston', which was supposed to be some kind of substance that made things burn.

[DuskY1991]

I'm doing a work piece on hydrogen for school now, this helped me to some things to look up about hydrogen and it's isotopes. Thanks!

[TheRandomDestruction]

i have EXACTLY the same watch as him. But the weird thing is i also wear it on the right hand (i'm right handed)

[goodoldjam]

I wish i knew a guy like this.

He could answer all my "Why Does" questions.

[joefos7]

@goodoldjam exactly you wont understand crap but you will feel fulfilled



[TeenageIronman]

@goodoldjam Its called learning, do it yourself and you could answer your questions.

[xXinsaneboyXx]

is water created during this reaction?

[a23444]

yes

[ginomw]

yes

[sharinganx12]

Omg if you see it in slow motion, you see a splash of water! Awesome!!

[tommatdan]

yes but in the form of steam - because the the reaction is verry hot

[m4ps]

It doesn't detonate, it deflagrates. Fancy a scientist getting that wrong.

[Drag0nfoxx]

Two deuterium nuclei? I read that a deuterium and a tritium nucleus form a helium-4 nucleus and a free neutron.

[tommatdan]

only in fusion - which only really happens in the sun but we have just about managed it on earth

[MegaCritic2]

i wish my old science teacher was on youtube like this because he was always wrong lol. you all would leave the funniest comments. this guy seems smart

[Travisdjtg]

Your a great educator. :)

[LedZepTheWho]

right at 3:12 look closely beyond the trees and the person walking stops and looks lol

[Crabs308]

That just so happens to be bigfoot.

[ratkinzluver33]

yea i saw lol

[wowggscrub]

so is that why water is so abundent on earth i though it was from asteroids?

[fugehdehyou]

it is from asteroids but thats prolly how H2O was formed.

[douro20]

2H2 + O2 ->2H2O

[edae13]

Lol eistein dude

[pepsibookcat]

The Wile E. Coyote references throughout these videos crack me up! Nice job, Neil.

[rjhrjh3]

When you do it again do it with a camera that can see the hydrogen burn.

[Hawkallica]

You guys should invest in a super high frames per second camera when you film your experiemnts!!

Thank you so much for all of your videos!!

[eltotoX]

Should've done it at night!

[jason123425]

einstein!!!!!

[laurdy]

watch the person behind the tree, they just like stop as if WTF was that

[Roddyoneeye]

How common is deutrieum ? Sorry about the spelling.

[ALAPINO]

0.015% - in the H contained in our Oceans.

[yz250f4stoke]

155. The Hindenburg Disaster

[KnexGod03]

The hindenburg burned because of the aluminium rocket fuel painted onto the bladder to keep it waterproof, not because of the H2. Hydrogen burns with a clear flame, not a red one, as shown in footage.

[TheFluorineMartyr]

I love how he 'happens' to a have a super-sized Hydrogen model lurking under his desk!

[NM020695]

Awesome

[PBandWinnie]

is the scientist holding a dildo?! lol

[saradawn6]

yeah, the guy with the wihte hair owns, kinda makes ya wanna fall asleep...lol sorry.

[BF2mods]

aahahhaa that scientist is HILARIOUS i laughed my ass off ahahhahaaaa ahahahah

Bwyahahahaha

[goldtoothproductions]

ive found a very easy way of making small amounts of hydrogen. magnisnuim is easy to find as you can buy pencil sharpeners that are made out if it but trying to find hydrofloric acid well thats just plain hard. if any one can tell me how to buy or make hydrofluric acid plz reply.

[turen1234]

why was no visible water formed upon reacting H2 with O2...

[Oz6102]

Because the Water is a gas. Here

2H2(g) + O2(g) = 2H2O(g) (g) means Gas while (l) means Liquid.

[tolokoko]

Don't quote me but with a gas the particles are expanded.

When they combine the water molecules are alot smaller.

Also the heat from the explosion.

Well that's my theory

[eltotoX]

Molecules don't expand or contract, it's the separation between molecules that changes.
