[henkman00]

why did it say this video was posted 47 years ago? :P

[Crowz]

You used different masses how can we compare the explosions...

[rommelfcc]

@adiostraitorobama

Agreed ^_^

[danrayson]

This vid had me goin' - "forkin' 'eeeeeell."

[Kalahridudex]

hydrogen-based economy: for the win!

[DragonFlyback256]

Truly educative video.

[RestlessMalevolance]

That blue flame isn't science!! It's GOD!!! I love sattire :P

[anonazero]

thats awesome!

[rmcdaniel423]

"hehe . . . significantly enhanced impulse"!

[terrymorse]

Very cool demo, thanks! I always knew (well, since taking a Combustion class) that hydrogen has a very fast flame speed, but there's nothing like seeing it in action to hammer home the idea.

[kendallton11]

0:50 forever.

[chuckooful]

wow..

[motanium]

There is non "Do not try this at home" label Be right back.

[isabellaaudrk]

Nice hair Asian women ***lushfmlk.info***

[HydroFred]

Hey, check out the HydroGun. This is truly a real spitfire.

[MinGophers]

Science is fascinating.

[DarkZerkerX]

How do you get gas hydrogen into a bottle?

[Orical001]

very cool

[SlugSwaggaObi]

@mistertymes lmfao!!! xD

[MisterTymes]

Now I know why the farts come out my--sphycter muscle.

[octavius909]

boring!!!!!



[Orical001]

@octavius909 shut your hole fuckface

[MalpaPL]

@octavius909

like your life and personality...gtfo

[fortissabrok]

It looks like he burns the crap out of his hand.

[flexikana]

What is Thunderf00t's point with this video? Usually he makes videos to prove religious people wrong, so i and just wondering what the purpose of this video is. If anyone can place it in some kind of contest for me, then i'd be happy

[helmetprod93]

@flexikana

Science is awesome, knowledge is awesome, explosions are awesome. No other reason needed for this video to be put here.

[Supremedeity]

@flexikana im sure he just finds this intersting and wants to spread the knowledge

[GravDiga]

Just like Chris Rock said...they can build a car that will last 50 years but where's the profit in that?!?!

[viking977]

hadoken!

[Nopiw]

@viking977 loled

[ZeroFossilFuel]

And people wonder if we can get a motor to run on 100% hydrogen/air mixture from water. Looks like I need to complete my gaseous hydrogen injected 2-stroke engine modified from a 4-stroke. Just when I thought I had some spare time. ;-)

Very nice video.

Z

[lynel1985]

@ZeroFossilFuel you could save time Z and use a small 50cc-199cc wankal rotary engine from a go-kart (2nd hands from AU$200ish) and use a factory gas injection system from a car harvested at the wreckers. I dont know about the US but we can harvest such SVI (sequential vapour injection) lpg systems from new model cars such as FOrd falcon/futuras or Holden/GM Commodores including injectors, lines, tank and mappable fuel/timing computer from AU$800.

[killerdeamonking]

muhahahaha nice im about to make hygrogen using baking soda and yes its possible

[LKR572]

ok maybe ill not try making hydrogen then

[adzug]

you mean god dint just say it? how beautiful is science.

[dycarbon1]

I am distraught by the Obama admin wanting to cancel the trip back to moon. :(

He is basically destroying the future of our species.

[VCat2006]

@dycarbon1 I don't think Chinese are a different species. Are they?

[dycarbon1]

@VCat2006

Did I say so?

[VCat2006]

@dycarbon1 Unless the USA is the only country ever capable of such, yes.

[dycarbon1]

@VCat2006

I never thought you could change the meaning of a word just like that. I must try it myself some day.

[patchesdf]

That is astonishing

[Mormonites]

Oh, I bet the wannabe Islamic Terrorists will enjoy this basic info.

[annthracks]

nice video, I now see why shuttle exhausts are not made of plastic bottles, ta :)

[happyidiottalk]

@annthracks LOL, most humourous! ;)

[PersonalPariah]

Now this was a good video.

Your latest ones, not so much.

[LiquaFoo]

that was very educational. I learn better with pretty pictures

[soylentgreenb]

@antjam666 Producing hydrogen gas from electrolysis is 50-70% efficient. You then compress the hydrogen gas to very high pressures put it into a storage tank using a considerable amount of energy. The fuel cell converts hydrogen gas back into electricity at an efficiency of ~30-60%, with the higher end being attained only at a lab-bench scale. The engine converts electricity to forward motion at ~80-90% efficiency. Round trip efficiency is ~12-38%.

[HectorL360]

do you learn this in chemistry?

[totheword3000]

the hydrogen one looked like a mini nuke.

[alJizzerror]

Burning hydrogen does not produce CO2 or any other pollutants. The only substance released is water. Therefore, hydrogen is a "green" fuel does not create greenhouse gasses and does not contribute to global warming. Hydrogen can be generated by electrolysis of water. If the electricity used to break down the water molecules is produced by solar or wind power; the hydrogen cycle is clean.

[soylentgreenb]

@alJizzerror What nonsense. Hydrogen is a very dirty fuel, if it is to be regarded as a fuel at all.

Wind and solar can't even compete in production of electricity; there's another factor ~3 handicap in favour of fossil fuels when you're making hydrogen; because all you have to do is steam reforming which is cheap and easy.

If you're advocating hydrogen fuel cells you're advocating for coal and natural gas.

[alJizzerror]

@soylentgreenb

Chemistry 101

Burning hydrogen: 2 hydrogen molecules (H2) + 1 oxygen molecule (O2) = 2 water molecules (H2O)

[soylentgreenb]

So? There are lots of ways to store electrical energy without releasing CO2. It just so happens that hydrogen is a particularly inefficient, costly and dangerous way to do it.

[Spartan09786]

@soylentgreenb what the hell are you talking about you nut?

[soylentgreenb]

Your inability to read and understand is a failing on your part, not mine.

[Spartan09786]

@soylentgreenb no, i read what you said and understood it perfectly well, what i meant was how can anyone be that fucking stupid? and the fact you didnt grasp that furthers the proof of your stupidity.

[soylentgreenb]

@Spartan09786 Your inability to point out any substantial error that I have made is rather telling. If you had anything interesting to say I don't believe you'd behave as a petulant child.

[highflyer4]

@soylentgreenb then use geo thermal energy which is unlimited and very powerful, expensive to first create but since it never runs out its cheaper then the long run. But no one ever cares about 100 years from now so the cheapest thing is usually used.

[soylentgreenb]

@highflyer4 Enhanced geothermal is problematic for a whole slew of reasons. Drilling costs increase much faster than linear with depth; it's not economically viable to drill 10 km wells for oil(which is much more energy dense) it's going to be even less viable to drill 10 km for hot rocks. EGS is not going to be viable across more than a few percent of the earth's surface, where you can get away with drilling only a couple of km, for any forseeable future.

[soylentgreenb]

@highflyer4 You have to redrill geothermal wells every once in a while to get rid of the crud that crystalizes in the pipe. Individual heat reservoirs run dry in a couple of decades due to low thermal conductivity of rock so you have to keep drilling new geothermal wells. Since the amount of power that comes per unit volume pumped is about 50 times less than for oil you have to maintain crazy rates of drilling in perpetuity.

[soylentgreenb]

@highflyer4 Enhanced geothermal is also able to produce small earth quakes, which have put a stop to at least one experimental EGS installation.

[soylentgreenb]

@alJizzerror Again, wind and solar cannot even compete with straigth electrical generation.

It is much more efficient to convert fossil fuels to hydrogen than it is to convert fossil fuels to electricity; this puts wind and solar at an even greater disadvantage. Arguing for hydrogen is arguing for fossil fuels.

[LooneyLopez]

@alJizzerror using hydrogen to power our daily lives is a waste of time, for one solar/wind power is not even close to 100% effeciency and given that, if we use energy to make energy, to use energy how could we keep up with the growing demand for energy?

[Wintblash]

google Doe's Account.

[ZuraJanai8988]

So... cool!

[shaneomac210]

And? is this some kind of highschool channel?

[ByronC900]

@shaneomac210 It's an education channel, yes. Not just for highschoolers though.

I'm a college grad now, and I enjoy watching Thunderfoot, and other educational science-related videos on youtube, to make up for where public science education failed me.

If it wasnt for Youtube channels like this, I fear I'd be rather ignorant.

[thetravellounge]

pure oxygen is cool too. we fill up coke cans with the oxy-acetylene torch, and stick some toilet paper in the end and light it. it goes RIGHT OFF

[Untemperedsteel]

Quite a big difference in the power of the hydrogen over the butane. The bottle shot away very fast with the hydrogen. Make a video of a home made rocket, if its legal where you are.

[Lavabug]

Good chemistry. Did you make the hydrogen gas yourself from oxidizing some metal in an acid? I made about 220mL of hydrogen gas that way once with Zinc and hydrochloric acid, was tempted to ignite it when I was done but I didn't think the sealed flask would handle it lol.

[uhila24]

what is this supposed to illustrate? advocacy for hydrogen cars?

[singedrac]

@uhila24 It's an educational chemistry video, like you'd see in a science class. That's it.

[hcnuup]

I'm not a scientist of any sort, but it has always fascinated me how much energy fuels have.

[BaMenace]

lol your teaching those terrorists how to blow u up.

[gr4tuitou5]

@BaMenace That's what I thought at first but then I thought maybe Thunderf00t wants them to try using hydrogen, failing miserably and blowing themselves up.

[TheAlaricPetz]

"PEOPLE LAUGH AT ME"

[BeondaPale]

lol @ "hehehe a significantly enhance impulse"

You'd make a good MAD scientist

[macfanpro]

Great video, but you made mistake of saying mot rockets are fueled with hydrogen. Some are, including the Saturn V, the Space Shuttle, the Delta 4, Ariane 5, and the J-IIB, but the majority of launchers, such as the Delta 2, Atlas 5, Falcon 9, Zenit, and the Soyuz, use a kerosene/LOX mixture, due to ease of handling. Also, the solid and hypergolic rockets are relatively common.

[mynameisdarthtater]

might i ask where you got the hydrogen from?

wait... on second thought, that might not be a good idea. a 10th grader like myself could do some dangerous things with that knowledge

[singedrac]

@mynameisdarthtater You can make hydrogen with a battery and a bowl of water, more or less. It's quite easy. Look up "electrolysis".

[gooyzit]

Don't lose your eye brows now.

[TonyBtheEG]

Nice post.  It's fucking science.

[yellowdart137]

we spend billions on wars and "drug control"

yet to do actual science its almost last.

although this is coming from a society, voting mind you, that thinks singers, movie/tv stars and athletes needs million of dollars. whiles it's teachers, researchers and scientists make almost bunk.

[Retardretroguy]

It's good to know I'm not the only one with that particular strange hobby :-)

[TheMistycan]

I like :) more videos like this would be cool. :D

[hifhif123]

0:50 Click this and watch it again and again... you know you want to

[TearsOfWar1]

OOOO pretty O.O

[MajorDestruction]

WTB moar videos like this. I love science in action.

[slysci5]

love the fact u use SI units so the whole world knws what ur talking about :D

also love how u use a supersaturated hydrogen explosion , sound effect would have been mucho appreciated ^_^"!

[mattiassollerman]

Diet coke and mentos is the fuel of the future.

[kirkey99]

makes me want a hydrogen car now!

[MathiusDragoon]

Apparently the flame speed of hydrogen is super sonic to get that violent of a reaction.

[Jonathanmcole]

WHAT HAPPENED TO THE ISLAM ONE!?

[Legendhalfliferrr]

@Jonathanmcole banned

[thenoobcannon]

assuming that your talking about the one with the south park clips in.

my guess is that it was flagged and promply taken down

[PhoenixBrave]

Whether you are into science or not, many people find explosions to be "cool".

[elgostine]

@PhoenixBrave of course, why do you think the mythbusters are so popular

[kareszt]

Wow hydrogen really loves oxygen.

[CrispProductionz]

Very cool!

[activiafibras]

WOW!!...was listening to your speech, but did not expect that! ^^ (0:52)

[ThatOneQuestion]

What the hell?! 36 people thumbed this down?? Why!? HAHAHAHA!! So pathetic!

.

Thunderf00t-awesome vid!

[TonyKnockOff]

@ThatOneQuestion

People just hate science, it's too hard for them.

[D3THFAN]

less explosions, more atheism

[Person1036]

@D3THFAN isn't the other way around?

[D3THFAN]

@Person1036 that isn't what i said is it bitch?

[gagaplex]

Science is fun!

Even though I'm more on the biological end of the spectrum, I enjoy the occasional glimpse of physics and chemistry also.

[aBRUSHforCONFUCIUS]

SPACE PROGRAM GOOD , dumb fools who think it waste-BAD!

[ScientificExploits]

Yep, without the space program we would never have the information technology systems that we all take for granted today. My only wish is that NASA would continue launching shuttles instead of using the Russian program. If new space technology markets are born I want them to be run in the United States.

[realyNobody]

@aBRUSHforCONFUCIUS let the unimportant/poor people starve go spaceprogramm!

[scienceminded]

@realyNobody

I'd just like to point out that just under $19 billion of the 2010 Federal Budget goes to NASA, while just over $1 trillion goes to the welfare of the people in programs like Social Security, Medicare and Medicaid.

[Zachdudeio2]

@aBRUSHforCONFUCIUS haha *cough obama cough

[whydie666]

great experiment

[wwickeddogg]

Is this a pro hydrogen-power video?

[jfinite]

BOOM!!!

[AEVautomatic]

suprised would take you for a insane carbon nutjob.

[TehShadower]

Hadoken!

[GrandBeagle]

Simply put: short ;awesome; T-Foot demonstrates basic chemistry in an impressive way

TY - made me grin like a maniac

[Frances3654]

woow

[supersmellyman]

Bazinga!!

[CanadianoftheCoast]

Excellent video. It leaves me thinking, however, that there has to be a better way of putting people into space besides igniting explosives beneath us...

[sentientmachine11]

@CanadianoftheCoast There is a better way just nobody knows what it is yet.

[CanadianoftheCoast]

@sentientmachine11 Indeed. It will be interesting to see what it is.

[singedrac]

@sentientmachine11 It's actually quite well known. An orbital ladder.

[UncreativeName222]

Thank you mr thunderfoot for showcasing GOD's creation. GOD IS GREAT!

[Exondriak]

@UncreativeName222 someone say...TROLL

[janeyanna]

@UncreativeName222 Yeah! All hail Odin!!

[PlaguedMan]

@UncreativeName222 You meant man's invention.

[1042802]

SCIENCE.

[TheBrazillianAtheist]

@1042802 science pwns conspiracy theorists and religion!

[lisamariefan]

Watching a bottle slam against the container wall like that was epic.

Lovin' the science, baby!

[Manford5847]

I didn't think this would be anything exciting, but thank you for reminding me how how fun it is to watch theory in practice. Very fascinating about the space shuttle as well.

[DeavonReye]

Quite fascinating. Thanks for posting this video.

[jacknocf]

now we just need to know how to put that kind of power in my car, and the would would be happy, instead of the doomed electric car. The electric car is a dead end road and is impractical at this point of human society. If we can use hydrogen in cars and just find a way to make it safe, there would be minimal to no growing pains in such a transition.

[Manford5847]

@jacknocf unfortunately while the hydrogen cell would provide an environmentally friendly and efficient option, both cost and safety are a major concern. firstly, the cost of changing all the state's gas stations into "hydrogen fuel stations" would be astronomical, and the states will likely never have the finances to go through with such a project. As for the safety of passengers, a garbage can of hydrogen furl ignited could level half a high school, and a fuel tanks worth could be devastating

[NickBlackDIN]

I'm not sure if someone has mentioned this, but doesn't the colour of the flame also show how hot is burning?

[Seargent363]

@NickBlackDIN yeah,white is hottest, and yellow is coolest.

[jxvwp]

@NickBlackDIN

Depends on the substance being burned.

But in general White or blue is hottest while red is relatively cold.

[therealmetroidmaniac]

AWESOME

[SensibleSkepticism]

Science rules.

[Johnfong1986]

very interesting indeed!

thank you for the video!!

[expiratio2]

Spectacular.

[Flyingtart]

Social studies and knowledge about the world is more my thing when arguing with religious people but I really wish I knew as much as you about science.

[IAMINDESPAIR]

the way he laughs . . . "he he he"

Priceless xD

[emancoy]

wow, thanks for sharing thunderfoot

[FlightIsLife]

Hahaha, this is awesome... hydrogen will make you shit your pants

[CrixMakin]

Interesting.

[xeyon]

the shuttles propulsion seems inefficient. I saw something on the science channel a while back about a new type of propulsion system they may have in the future. i dont remember what it was but it burnt blue and wasnt gas but electric i think. Anyone know what im thinking of?

[PaulTheHeritic]

@xeyon You're probably thinking of ion propulsion. While efficient it doesn't generate much thrust. They are planning on using it once a craft is well clear of the planet.

[DanLightning]

Wow... just wow... the bottle was like a mini Hindenburg xD

[HarshDiscipline]

Cool video : )

[Fab44Me]

Thunderfoot doesn't do 'religious debunking shite'.....he 'debunks religious shite'. Seriously, though...this was very interesting.

[jungleman68]

what is hydrazine like?

[paulbottomley42]

This reminds me so much of the old BBC Open University programs.

That's not anything to be ashamed of, either. I used to love staying up at night watching those things. I just wish I'd been slightly older and better able to understand them.

Then the OU went away and the best we could do for a while was the Christmas Lectures from the Royal Society, but the last one of those I saw had been dumbed down to the point of depressing futility, too. We underestimate our kids far too much :(

[Prelude610]

Nice - clear, straightforward, and with a touch of humor, just like in the "Creationists" and related videos. Keep it up!

[The3irik92]

Cool!

[antonyhamill]

Cool! Now try it with a fart....

[mudchair16]

These videos > religious debunking shite.

[AtheistMr]

@mudchair16

Debunking religion is never shite!

;)

Seriously, both are great, but I prefer some theist thrashing.

[derfisch78]

@mudchair16 Agreed.

[IronManTalks]

Awesome!

[erin321321]

thunderfoot laugh reminds of someone i used to play chess against in school. he'd do that laugh right before he took my queen.

good video. i wish i got to play with combustable chemicals

[Sebas3440]

H = BOOM! :o

[ebullock43]

@TruthfulChristian temporaldisplacement made no claim of being "more righteous than God". He just showed that he was at least as knowledgeable about the Bible as you.

I think most of us here aren't too concerned about "getting saved." Personally, if it means I have to stop using my brain, quit enjoying life, and get mean-spirited, I'd rather pass.

[JoystickHero1991]

The world is so awesome. :)

[ebullock43]

@TruthfulChristian It is you. If he's wrong, just use science to prove him wrong. That is, if you understand science. However, if you've made it a life practice to hold all scientific knowledge in contempt, then of course it probably won't make any sense to you. We live in reality and purposeful ignorance does not make science false, no matter how many tantrums you pitch about it.

[ebullock43]

@TruthfulChristian You're kidding, right? You think igniting a few drops of hydrogen or butane is illegal? Have you used a grill lighter?

I suspect your negativity is a knee-jerk reaction to anything Thunderf00t does because he has so effectively exposed creationist falsehoods in his past videos. I mean, you didn't watch this video because you wanted to learn something, did you? Aren't you just trolling for something to bitch about?

[GuppyPal]

sweet! Thanks, TF.

[cobrompton]

We need to save the Constelation program!
