Hydrogen Explosions (slow motion) - Periodic Table of Videos

[@lanswipe]

"and they're left in the middle feeling a bit stupid because the house has gone" That's the best thing ever.

[@kigozimuhammad]

lanswipe I have watched several of his videos and professor really knows how to throw shade on people or things really quick . His minutely savage

[@ITACHI-ov1nn]

Can you tell me how hydrogen can be stored

[@caesarcch3879]

I came to the comment section just to say that. Oh man I laughed so hard xD

[@sanjamilosevic927]

ROFL >D

[@prdoyle]

Came here to say the same thing. 😂

[@S4R1N]

As much as I love the science of it all, I can't get passed how gorgeous the H only balloon explosion was.

[@benhague9579]

I have a hypothesis as to why the flame is red. On the inside of a balloon there is a fine powder to prevent the balloon from sticking and tearing when inflated so as the balloon pops it would be thrown into the flame and possibly burning tremendously quickly thus causing the red flame.

[@lsrasr]

i think that fine powder might just be latex buddy

[@CatatonicImperfect]

that's been my hypothesis as well. could be corn starch, talcum... what would burn red?

[@Nexus2Eden]

You make me proud to be a Chemical Engineer, Professor. Your humility humbles me.

[@smartereveryday]

In the future feel free to leave people like this on Brady's Channel.

[@1.4142]

1 like? hi destin!

[@blackdeathghostye6654]

@@1.4142 almost jumped in happiness when seeing destin

[@marcelzatko9105]

Chemistry is so amazing teaching you how all these substances interact with each other. Fascinating really.

[@LowYummy]

Marcel Zatko it is dangerous. Like mixing Hydrogen and Oxygen to make Water... it is..... Explosive

[@smartereveryday]

It's like Where in the World is Carmen San Diego with that guy. Who knows where he'll pop up next!

[@1.4142]

ayyyy

[@noelmathew157]

Why this doesn't have a lot of views....I'll never know!

[@Duncan_Idaho_Potato]

I really like Professor Poliakoff. Not only is he a good scientist, a consummate science communicator, he also seems to be a kind, warmhearted human being. I aspire to be all of those things, but especially the last one. You're a role model, Martyn. Please never change.

[@smartereveryday]

I must have tainted it when I caressed it in the last video. Sorry about that.

[@ishan4363]

hey a great fan of yours, saw you at veritasium

[@ActualGenius]

You can tell a smarter person from a less knowledgeable person by their willingness to be proved wrong.

[@prakharlondhe3876]

that's amazingly true :D

It's actually 100% independent. It just shows how much pride they have. (I've seen this BS claim many times. It feels like just some humbleness-philia)

[@elvis633]

I love the professor, i wish he was my grandpa so i had someone interesting to talk to.

[@brfisher1123]

I love high speed camera shots; they reveal things you normally don't notice.

[@Popsomechicken]

"What happened?" "I lit a match and then my house was gone."

[@CursedJoker]

I think there is room for an entire channel for video of this kind. One chemical or physical phenomena explained in detail with the help of the high speed camera.

[@HellzGamerZone]

" HAHAHAHAHA I LIKE YOU NEAL" made me laugh

[@Hysteria98]

The fact I subscribed to Vsauce, SlowMoGuys, BradyHaran and SmarterEveryDay around the space of a month (and not even from recommendation, just coincidence), and then I find in my inbox, collaborations between the 4 just blows my mind like i'm a kid watching a cartoon crossover again. So much respect out to all these people :]

[@jassahib]

Thinking about the Martian bought me here.

[@DynamixWarePro]

This is great stuff, with technologies like this, you can learn so much that before you couldn't. High speed, not only amazing to watch recorded footage from, but you learn so much. If I ever come into a lot of money, I'll have to get myself a high speed camera!

[@pranab0343]

looks like sun

[@hdsf1066]

Cuz the sun is made of hydrogen ( a hydrogen core)

[@tommos1]

i was going thru withdraw symptoms during christmas. finally a new video.

[@nyxato7649]

I LIK SEINCE

[@frizzloko]

It is so moving to see someone so informed and educated in any topic getting that exited about being wrong. He is truly an awesome dude!

[@mundotaku_org]

This channel deserves more viewers.

[@Suro_One]

This man right here. He's a genius. Takes criticism seriously, studies it and even gives a formal reaction to the critic. This is the true essence of science and technology.

[@laserfloyd]

The beauty of science; when you have an idea about something and it can be changed based on an observation. This was a brilliant video and warranted a verbal "wow" when I saw the second balloon react that way. Keep it up!

[@ShiroKage009]

The best explosion I saw in slow motion, in terms of showing some of the thermodynamics involved in combustion, was captured by Mythbusters in their "Exploding lighter" episode. It shows a delay between the release of the propane and the start of the ignition. The best part was when the initial flame, which was the lighter lit before being struck with a golf club, went out during that period and then the reaction started from roughly the same location the flame was in.

[@bendup5590]

I don't always like videos, but when I do I'm liking periodicvideos

[@CaptTerrific]

I love how beautifully simple the letter-writer's experiment was :)

[@danial367]

This was amazing! I can't wait for future videos. They are definitely going to be the best videos you have ever done and you deserve all the success that is sure to follow!

[@LabNYorkie]

I wish my chemistry class in high school was like this. Imagine how many students would become future chemists if teachers could find a way to make the class exciting and educational.

[@dizzymetrics]

Oh man, I'm so ready for all these slow motion vids.

[@Y_A_Z_F]

Destin is quickly becoming one of my favorite youtubers.

[@mcvoid1]

I think with this video the channel has gone from presenting science to doing science, where the making of the video itself has lead to an increase in knowledge.

[@AlucardNoir]

exceptional video brady, congrats to you, niel, the prof and paul

[@flashzee]

i like every clip that you upload. always wanting to gain more knowledge in every thing

[@saintron60]

I love this channel. Had I known they were going to do this experiment I would have advised them to use HHO as I have done when using my water splitter. You get a perfect match on the hydroxy combo. The reason the gas ignites before the balloon appears to explode is illusion caused by the fact that in a mini second after ignition. The gas has expanded and is already in the process of collapsing and turning back into water by the time the balloon pops.

[@Sarjsh]

The thumbnail is the single most epic picture ever!

[@xanshriekal]

This is amazing. I never realized that the balloon pops before the gas ignited, or the huge difference in speed between the hydrogen balloon and the hydroxygen balloon.

[@Nimbus3690]

amazing. ppl like this and paul (is it, the emailer?) move the world

[@jevicci]

Wow. That bit about the explosions separating and people surviving in the middle blew me away (no pun intended).

[@TheSage555]

I have never been as excited about the emission spectrum of hydrogen as I have after watching this video.

[@ChaitanyaShukla2503]

excellent video. would love to see some more of these videos shot by high speed camera.

[@xenocideac]

I really wish more comments on youtube were like this one. I completely agree with you Iceus

nah, i allways thought it's your mission to get one smarter every day. Here you have him, now make him smarter. ;-) Btw. love your channel as much as brady's, vi's, Michael's, Derek's, cgp's.... You all do fantastic work and i like the way you work together! It inspires me to do it in a simmilar way on my videos.

Thank you for the opportunity to see this experiment :)

[@rcdude29]

Destinw + periodicvideos = awesome!!!!

[@PMW3]

what I find fascinating is how much the hydrogen explosion looks like a stellar nebula

[@AlexanderKleeZH]

these videos help change the way that science is taught! I'm really excited for all of us :D

[@danielmadar9938]

Thank you for your humility

[@ThomasCTC]

thank Destin from Smarter Every Day

[@danniboi07]

This is my favorite side effect of having studied sciences in school: the ability to admit you're wrong and grow from it. If you're proven to be wrong, that's great, because more truth is brought to the world! There'd be a lot less fighting in the world if we could get our egos out of the way and be willing to look at evidence to come to conclusions and agreements.

[@tarassu]

This is what i call cooperation. Science+science=new knowledges

[@aintnobiscuit]

wow, this blew my mind. I've always loved chemistry/physics. thank you for the amazing video

[@lampyman101]

it is certainly the understatement of the day.

[@AgainsaidBen]

What an interesting experiment. I was fascinated the entire way.

[@endimion17]

Ignition of saturated fuel such as a pressured blob of gas is a perfect example of chaotic system and fluid dynamics. It's the sudden directed movement of the gas that's important, not the fact it's glowing or the fact it's hydrogen and oxygen reacting. Blowing into gas causes vortices, pulling a paddle through water causes vortices.

[@aisles23]

This is just what I wanted to see... The Hindenburg accident would have been another whole story if the hydrogen was mixed already with oxigen... nice to see the smarter everyday guy helping you!

[@fallingwater]

"It's always good for a scientist to be proved wrong". Spoken like a true scientist! I only wish more people thought this way and didn't take it as an insult when they're presented proof against their position.

[@Chaos3131]

Excellent answer, I don't think anyone could top that.

[@SponzyParadox]

Brought back fond memories of highschool Chem! Thanks for the video!

[@MsLadyDarkside]

I just subbed a few minutes. My fiancee loves your videos and he sent me one because he knows I love learning new things about all things science (I am just terrible at the math part) and... I just have to say this... You are so cool!

[@endimion17]

One more thought. The dust in the balloon is usually cornstarch. When the ballon skin snapps, cornstarch aerosol would be flying everywhere through the hydrogen. Burning cornstarch aerosol has an incadescent carbon phase. If you really want to know what's the source of the color, use a spectrometer. If it gives off full spectrum, it's incadescent carbon. H2, O2 and H2O can not give off this kind of light.

[@judyjennings7668]

Wow, explosions make people so happy. Look at those smiles.

[@81mrsmitty]

For those wondering why H2 gas looks red when it burns when you probably always heard that it burns colourless. I worked at an oil refinery and we produced pure H2 gas for hydrocracking heavy oil into light oil. If we had an excess of hydrogen and needed to flare it off during the day, the flare colour would be nearly colourless, but if we flared it at night it was a pale red colour. I believe that the colour is such a pale red typically in daylight you may not see the red colour to the flame

[@tapetedepadaria]

The first explosion is so just too beautiful!

[@rich1051414]

It's hilarious Destin got himself such a cool high speed camera and decides to hold it instead of mounting it. It is cool to see the delayed startled reactions tho :)

[@antonc81]

2:30 - "It's always good for a scientist to be proved wrong". Well said, Professor. So many seemingly intelligent people fail to grasp this about the scientific method.

[@StevenAlpert]

Wow, i feel much informed, despite only doing this experiment twice myself in the past.

[@slappy2099]

ITS DESTIN FROM SMARTER EVERYDAY!

[@jimsvideos7201]

The mixed-gas balloons would make interesting light sources for portrait photography of particularly steady-nerved subjects.

[@ASilentS]

The new season begins, yay!

[@gutspraygore]

"...and they're left in the middle feeling a bit stupid because the house is gone." The image this statement created in my head made me burst in laughter. yes, indeed. I suppose there would be cause for embarrassment. Thanks for the video. The hydrogen igniting is gorgeous.

[@jiberish001]

Thank you. I was not thinking about searches. I almost never 'search' for videos on KZbin. Some times I overlook the feature entirely.

[@addjewelry]

That was so cool! Love the high quality slo-mo.

[@chiralSPO]

I think this source of the colored flame is actually the solid powder lubricant that nearly all balloons are sold with. This is often talc or cornstarch, either of which could color the flame yellowish-orange (talc can have sodium or calcium impurities). It is known that metal salts or boron compounds can be added to balloons to change the color of the explosion as well. Clearly the flame produced by the stoichiometric mixture in a balloon shown here is much brighter than that of a stoichiometric flame in a HHO torch, so it has to be more than just the ratio. I propose washing the balloons very thoroughly with water, and then testing both pure hydrogen and mixed gases with the same high-speed footage.

[@simonnance]

surely to ensure all hydrogen is consumed before it can be heated and produce a yellow flame, an excess of oxygen is needed. I'd love to see a slow-mo of a balloon with equal parts hydrogen and oxygen. Used this demo today to teach stoichiometry and balancing equations, great stuff!

[@Johnokai]

Well done Paul, whoever you are

[@themomaw]

This is because the color of light emitted by an incandescent gas (a flame) is different than the color of light that is reflected by a material. Sulfur is yellow when you have a piece in your hand, but burns with a bright blue flame. You might change the color of the flame a little bit (heavily inked paper often burns with a slight green tint, for example), but changing the color of the balloon would still leave it being almost entirely rubber.

[@dnstone1127]

The mad proffessor is still alive

[@Eliphas_Leary]

Suggestion for a viewer feature: a "periodic slomo videos reaction" video, where us viewers send Brady videos showing our expressions and reactions while watching his amazing stuff.

[@ZainSharaf]

Good work Paul

[@hugge123456]

Good job, Paul!

[@TerrabyteX]

Amazing experiment professor

[@mrruggbuurn]

That tie is awesome!! I want one!!

[@therealjordiano]

great video :D really loving this slow motion camera

[@endimion17]

Stoichiometric mixtures, if intimately mixed (gases are always like that) give the fastest reactions because the right molecules are at the right places in a given point in time. 2 H2 + O2 -> 2 H2O If you increase the quantity of one reactant, there'll be a surplus which dillutes the mixture and slows down the progression of the reaction. That's especially visible with reactions that burn.

[@andrewdescant]

Having watched many slow motion videos (on you tube) of balloons popping and of gasoline igniting I was not surprised by the hydrogen only video, but I wish I had taken the time to guess what I thought would happen. The speed of the mixed explosion did surprise me.

[@sidmarklong]

Q. What is the difference between a bunsen burner, and a balloon while burning hydrogen? Next Q. Is the atmospheric content of the room you are doing this in, higher in nitrogen/carbon-monoxide/oxygen etc? There is some sort of reaction occurring. It may just be the fast occurrence of combustion while sudden exposure from the match flame breaching the membrane, aka, balloon skin, to the natural atmosphere and unregulated mixture.

[@vava54]

This channel is amazing.
