  • MAD SCIENTIST ALERT

  • this only happens if you DROP it in water, if you use that long pincer thing and have it only thouching the waters surface, it happens differently.

  • There is no Good or Evil, just Power.

    Starwars.

  • I'd like show my reply video to this, but 1 I'd likely get in trouble when someone recognizes me and 2 Tfoot calls be a n00b without a doubt...

  • Would the explosion be more violent if you ground up the potassium into dust and then threw it in the water? It seems like it might be able to release it's energy faster because it would have a bigger surface area to contact with the water.

  • this video was proven fake. potassium isn't explosive. It boils in water and flares up, but it doesn't explode.

  • Yeah, but it ain't Caesium is it.

  • so wait.....

    are banannas safe to eat?....

  • Potassium engines anione, i smell a Nobel.

  • @TheXenomorphZ

    That would be extremely difficult to make and run, because it would not only be hard to harness the energy of such a speedy reaction, you would also have to provide a constant stream of potassium. This would not only be hard to keep, but it would be extremely expensive. Rember that alfa aesar charges about $2 per gram in bulk, excluding shipping hazards.

  • in a closed container,having cold low pressure steam,what would the reaction be.

  • After seeing this video, I have taken potassium off my wish list for Christmas.

  • I don't tend to think of 250mg of anything as "about a quarter of a gram." Instead, I think of it as "exactly a quarter of a gram." ;)

  • @Wikimancer

    Perhaps it was not exactly 250mg, but somewhere close to it, and merely said that for convenience.

  • Potassium > magnets

  • Potassium is an integral part of our body. Without potassium we die. Oxygen is another highly reactive gas, without which, multi-cellular life is likely not possible.

  • i fall asleep listening to this guy

  • Can you help me with something? Some people claim that the Dead Sea Scrolls have a reference to some biblical characters. I want to disprove this. Can you help me with this?

  • what would happen if the potassium hit the water in a vacuum?

  • @newjsb123 the water in vacuum... Are you serious?

  • @csikiati a Simple question and I'm still curious of the answer.

  • @newjsb123 you cannot have water AND vacuum. If the pressure above the water is 0 (vacuum), the water will evaporate to balance it out. If this is in a closed container, you would have cold, low pressure steam. There's are some classic formulae on wikipedia (gas laws)

  • Argon walks into a bar and orders a beer.

    The bartender says, "Sorry, we don't serve noble gasses here."

    Argon doesn't react.

  • @EuNaoBeboDetergente

    A room temperature supra conductor walks into a bar and orders a beer.

    The bartender says, "Sorry, we don't serve supra conductors here."

    The supra conductor leaves without putting up any resistance.

  • oh man I love the periodic table of videos! I thought your title seemed familiar.

  • Can't wait for Rubidium and Caesium!

  • So if you get Potassium on your skin, how do you wash it off?

  • @weeeezzll alcohol!

  • @botlight Pure alcohol i'm assuming?

  • @weeeezzll HPLC degree alcohol hehe,,,if not u drink it to ease up the pain

  • @weeeezzll

    I was told that if you get potassium on your skin that you better grab a fire blanket because it'll react with the moisture in your skin lol also when we did this experiment in my high school science class (for some reason college level classes won't do it) my teacher used acid instead of water and he set the ceiling tiles on fire

  • I know that is maby the wrong channel for me, but can you talk more in 'noobish' style, i find it very interesting but very difficult to follow.

  • @xzaz2 No. He can't. If you can't follow in the first view. Watch repeatedly until you do understand.

  • More waiting, baaaastard :D

  • You need potassium to live. Without it your heart could not contract and you would die. Potassium is really evil huh?

  • @nazra7 I think you've gotta distinguish between potassium the metal and potassium ions. Very different animals.

  • @outlander271 Or perhaps Thunderf00t needs to?

  • @nazra7 Not really, when one says "potassium" on its own, it means metallic potassium and not potassium ions. The two are only confused by the non-scientific laity in magazine and newspaper articles on diet and health etc.

  • @outlander271 When you target a certain thing that has sub groups and do not specify what sub groups you refer to, I think its safe to say you're not just referring to a sub group of that thing, but all groups of that thing.

  • Worry; trolls will spam Mr f00t. I would bet that by now the email put in the description has been subscribed to every creationist web site there is.

  • I don't believe in potassium.

  • Now I need to get me some Potassium :)

  • There seems to be a lot of explosive gas on this page. Too bad the minority comes from the video.

  • Comment removed

  • @omarthegenie lmao nerdgasm

  • thunderfoot probs had the biggest nerdgasm when he saw that footage

  • I like the Christian dating ads across the bottom of the vid lol

  • EVOLUTION??? THIS VIDEO SUCKS

  • Comment removed

  • @AresExodus You really are a sad person, are you offended he used the word "Evolution"? Any process of formation or growth; development: the evolution of a language; the evolution of the airplane. A product of such development; something evolved: The exploration of space is the evolution of decades of research.

    In Biology: change in the gene pool of a population from generation to generation by such processes as mutation, natural selection, and genetic drift.

  • @artblack01 I was being facetious.

  • @AresExodus That's not obvious.

  • @MxC1337MxCsh43d The phrase is obviously a joke, to get the attention of silly people who react to silly things in silly ways.

  • 'tresting

  • Somethin which came to my mind:

    You say that it is a coloured gas.

    But you also observe that the gas bubble you see is encompassed by water.

    That means, you don't actually know (yet) if the gas is colored, it could be just the water.

  • That was a decent piece of work. Thanks.

  • OMG I watched the potassium in chemistry the other day and everyone loled at the cool hair man ;')

  • lol second einstein

  • "250mg, that's about a quarter of a gram". Thanks, bro.

    :P

    Just kidding. Love the videos.

  • Made me remember McGiver :)

  • @hobblehonker

    You seem like you're a lonely person.

    Make sure you get a hug, sometime today.

    It'll help.

  • @hobblehonker Dude, not cool. This is Youtube, we're all highly civilised and very friendly. You should live up to that standard.

  • @hobblehonker Just looking at how you put this comment together, I can see you are clearly below average intelligence. Education and a basic human ability to clearly exspress your thoughts and ideas, are both key factors in effective trolling... Take a deep breath, slow down and just try ingeneral to perform a grade 8 or higher level. Thank you.

  • @hobblehonker So no to drugs.

  • @hobblehonker So no to d r u g s

  • @hobblehonker Considering how you react to people who don't believe as you do, how can you justify that you don't deserve the same fate? Because you clearly would not be deserving of any sort of heaven. That's probably why you are so angry, because you know such things as heaven and hell don't exist and it makes you bitter.

  • It would be even more fun if you mixed sodium and potasium together before dropping them in water.

  • Potassium is in bananas,hence bananas are evil.That disproves Ray Comforts claim,that bananas are made by a loving god.

  • @gotohellfast I knew bananas were evil. I caught my girlfriend with one. She wasn't eating it. I said that's my job. lol

  • @stevjen1 Well if you did your job right....

  • @gotohellfast bananas contain more protein than potassium. (: just a fun fact.

  • @herb414

    thats kinda expected. its like saying there is more carbs than potassium. its different. thanks for the fact though :)

    what i wanna know is, where do you get this potassium metal!?

  • @TheRealColinChan I know, but everyone says "Eat bananas because they contain a lot of potassium!" I just wanted to clarify it. (:

  • @herb414 ya and you eat fish for mercury... yes and you also have arsenic in your body... but like everything in the universe, the more of it, the faster it blows up (or in our case die)

  • @herb414 and birds don't pee, they have two types of poop

  • @gotohellfast I am Ray Comforts and you're dead wrong! If Potassium is in bananas, and bananas have water, how come bananas don't blow up?

  • Only in youtube comments will you find people cussing each other out over the boiling point of potassium. Beautiful.

  • @GenXRanter and now, suddenly, everone's a nerd...:p

  • @GenXRanter How fucked up is that? Even if we ever manage to escape the religious bullshit in a pure science video, there will still be people pissing on each other over anything they can.

  • @AM0destProposal The Potassium isn't going to its boiling point.  The boiling point of potassium is 759 degrees Celsius. There's simply not enough energy produced to generate that kind of temperature from .25 grams of Potassium. That's the point.

  • @AM0destProposal I come along state solid principles that are integrated into chemistry and you want a fucking math lesson even after quoting terms from the principle that I got my findings from. Thunderf00t posts a video stating that the temperature from chemical reaction will grow, assumes that the Potassium is molten, assumes that the fucking Potassium becomes a gas because of armchair math, doesn't even bother checking the fucking temperature and you have absolutely no problem with that.

  • @AM0destProposal "what mechanism stops the temperature rise?" CHEMICAL THERMODYNAMICS. When you pull shit like: "if the reaction were to continue at that rate, then the metal would boil" out of your ass and expect me not to say you're spouting nonsensical bullshit is ridiculous. There's going to be an end to the reaction at a certain point which is related to how much stuff is there. That's how you can conceive the energy from the chemical fucking reaction. Prove it? Fuck you. I did.

  • Any high speed of tossing a cat in water? We then have video walking on water is common.

  • Comment removed

  • @NephllimFree NO HE DID NOT GOD DAMN IT :)

  • Comment removed

  • @NephllimFree Nope sorry that's not how reality works.

  • @NephllimFree It was the Flying Spaghetti Monster actually.

  • @AM0destProposal You're the one that keeps replying to me with armchair science. If you don't spout nonsensical bullshit, I won't respond to it. Simple as that.

  • Get you an even higher speed camera and throw some casium in water, now THAT would be awesome!!!

  • @timh651 I don't think that's legal, like anywhere. (if I didn't fuck up my elements again) Isn't casium almost impossible to get because of how strongly it reacts? or is that only limited to us civies?

  • @hornylink no it's just very expensive like $150 a gram plus hazard shipping

  • @AM0destProposal It's not a fucking debate you moron. It's science. It either is or isn't. Getting 0.25g of Potassium to chemically react with water and get up to 759 degrees just isn't fucking possible no matter how much of a hard on you have for Thunderf00t, the pseudo scientific idiot.

  • @Meiz79 Science isn't up for debate? That's all science fucking is, experimentation and debate. As for the impossibility of the reaction, got any numbers to back that up, or are you just being a puissant?

  • @hornylink A debate is something where you have a discussion revolving around opposing viewpoints. This isn't a debate. It's just my facts versus bullshit armchair science maths that doesn't take into account other facts that have already been established. Facts win, every time, no matter how much you like this broken headed video. Things like thermodynamics from a chemical reaction are what I used. The numbers you're looking for are in my comments. Puissant is a French word for powerful.

  • @Meiz79 *cough* anger management *cough*

  • Potassium Cyanide is more evil....

  • I feel more intelligent from watching this video. Potassium is awesome stuff. 

  • @TheReverentPantheist Really thats awesome you are related to a genius of science!

  • @MicrosoftsourceCode

    Um Thunderfoot is a Scientist and a Chemist. Not some guy starting School, as someone Studying the natural sciences I happen to think his theories are very interesting.

    Excuse me why call him a twat for perhaps being the 1st person ever to document the release of potasium gas from the reaction of potasium and water. It isnt "shit".

  • @QuantumOverlord I love science but I just find this guy boring. Nothing new that's going to change the world. And I challenge you and all the thumbs down crew to prove me wrong

  • @MicrosoftsourceCode Science isn't about changing the world.

  • @Emanresu56 What a bold and meaningless statement.

  • @MicrosoftsourceCode It's true. There is nothing within the scientific method which says you must change the world, or else.

  • @QuantumOverlord If he's a chemist, he's the worst fucking chemist. You don't get up to 759 degrees Celsius with .25 grams of K and H20.

  • @Meiz79 wait, this is why you're flipping your shit? because of a claim he didn't make? He said if the reaction continues linearly the potassium will boil, he then shows us the footage, we see it's not boiling, and he doesn't claim otherwise. Well, at least you're not yelling about god, that's an improvement when Tfoot's involved.

  • terrific teaser, can't you get any funding from a camera company for the video, after all which camera company will be the first to film this exciting event?

  • Just had to drop the word "evolution" somewhere there didn't you.

  • I was sort of expecting an image of the Virgin Mary at 0:51.

  • I'm never eating bananas again.

  • Hey..........What about the 385mg of Potassium in my daily Banana....What is that doing to my internal organs?

  • @movement26

    Nothing at all harmful. In fact, potassium is an incredibly important substance in the body. The potassium in a banana is actually in salt crystals or in solution. In your body, it is dissolved into the blood and is essential for the operation of neurones and many other functions.

  • @nashertheatheist .....Thanks nasher.

  • @movement26

    Almost certainly all of it is in the form of dissolved ions or bound to negatively charged ions. No problem there.

  • Fascinating!!! I can hardly wait for the part ][.

    However..;

    Potassium is NOT evil! It's just a little reactive ;-)

    Lots of chemical reactions have positive feedback loops that if left unchecked, can lead to vaporization and detonation.

    Evil requires intent and Potassium is just a metal.

    Thanks for a great video!

  • oh come on i want to see potassium gas!

  • Sir Simon Milligan: "EVIL!"

  • show off :P

  • great clip, man

  • I want this to see in Time Warp on Discovery Channel :P

  • Fantastic!!

  • Awesome video. It's amazing how complex, beautiful, and surprising something as... well known as this experiment can be. Kudos TF.

  • @TheENTERRAPTURE17 Yeah, I'll get right on that, but I need to tend to my unicorn garden first.

  • @TheENTERRAPTURE17

    Sir, I will gamble all the money I have on your predictions not coming true. You have no evidence.

  • @nashertheatheist Better don't gamble on the big bang.

  • @BigBangNeverHappend

    How would you explain the redshift of galaxies and the cosmic microwave background radiation if the big bang did not happen, then?

  • @nashertheatheist Redshift actually debunks the big bang. Study the case on quasars. Background radiation doesn't prove or disprove any theory.

  • @BigBangNeverHappend

    I have watched the featured video on your channel and left a comment there (you set it so that only approved comments were shown, so you will have been notified of my comment). Could you please provide some kind of peer-reviewed source confirming that quasars are found around nearby galaxies? Because this is not the scientific consensus and I can find no mention of anything even remotely like that.

  • @Meiz79

    QQ More! :)

  • @AM0destProposal You want to just throw the hydrogen on to ∆H for the chemical reaction itself? Ok. So 5kJ per gram of energy per gram of K = ∆H for the reaction, he used .25 grams and for shits and giggles, lets say the reaction instantaneously created .25 grams of hydrogen blowing all laws of conservation out of the water and we get, not even fucking close to 759 degrees. You could apply thermodynamics, kinetics, the oxygen in the air and it would still not even come close.

  • great video! i like the vids with more science & less drama with religous folks

  • NOOOOOOOOOOO!!!!!

    Fucking cliff hangers. Dam you thunderf00t, but I will be back.

  • @Thunderf00t Neil doesn't need a gas mask! He eats potassium for breakfast >:D

  • @AM0destProposal @AM0destProposal What sources? You mean thermodynamics? ∆H for the reaction doesn't go up to 759 degrees Celsius. Also, chemical reactions don't keep producing energy exponentially ad infinitum. You've got about 5 kJ of energy per gram of K in 2K + 2H2O -> 2koh + h2. Now I've done most of the work for you and I'm even allowing you the benefit of the most pristine ideal conditions. What's ∆H in Celsius for the potassium? Armchair science indeed.

  • Comment removed

  • That guy had a full beard & head of hair before he dropped the K into the water

  • @AM0destProposal It's not "hardly a transgression" if he's too stupid to realize that taking content from a reputable scientist's video archive and referring to him as "the Potassium is evil" guy. Not only that but then he goes on to say that the exothermic reaction goes from 60C to 700C in a matter of seconds in a bucket of room temperature water, which is fucking absurd armchair science. If you want real science, watch the entire periodic video which shows how to actually melt potassium.

  • @Meiz79 First of all, when you post something on youtube, if you don't claim copyright, it is fair use. Secondly, his clip of periodicvideos basically consists of referencing "hey look, other people have blown this stuff up on youtube before" if you actually listen to what he is saying. Nowhere does he claim credit for anything they did in their video.

    You have to be literally, fucking, composed of 100% retarded to not understand this. Go find something else to rage at dipshit.

  • @Aezelll You're missing the point entirely. The point is to take a video from a prestigious scientist on Potassium that uses actual science, edit it, throw it into your own video on Potassium, give them the credit of "potassium is evil guy", and then proceed to make a pseudo scientific video with potassium makes you a fucking moron. Especially when you're trying to do something in the name of science itself only to misinform all who watched it.

  • Damn! What's next? Splicing?! Wicked work man!

  • Sponsor you after taking content from periodicvideos and crediting the "person" as " Potassium is Evil guy"? His NAME is Martyn Poliakoff. An actual scientist that is appointed CSE, and is even now about to become the foreign secretary of the Royal Society. He's definitely NOT the "potassium is evil guy" and for you to credit him as such, to rip their videos without their permission and to give him and his colleagues such a lackluster mention only to ask for money... seriously, fuck off.

  • @Meiz79 Relax it' called fair use and he did infact credit the guy no harm done.

    He just borrowed the footage to and then explained what was going on, in great detail and in a way people can understand, he provided a service you need to chill out or get off the internet because if this upsets you then you have no business being here.

  • @silentsuffering It's called taking shit that doesn't belong to you and then not even bothering giving the source proper credit. If you can't tolerate comments that defend actual scientists from pseudo scientists that take material, don't credit said scientists and beg for money, then shut the fuck up or leave yourself.

  • @Meiz79 It's dropping potassium into water it isn't exactly ground breaking stuff, science doesn't belong to anyone it has no owner and anyone can drop alkali metals into water, again chill out or bugger off.

  • Comment removed

  • He's talking as if he's about to run out of breath,

  • 45 dislikes? Who dislikes a video about potassium with explosions??

  • Potassium isn't evil - it's awesome! Research indeed rules!

  • Hell is evil. forget potassium.

    Hail Satan

  • I have nerd blue-balls.

  • I personally prefer Caesium in water... Shame it explodes violently... But Francium? Well, that's illegal.

  • @killerkyle54 No it doesn't. While it reacts faster, the atomic mass is much higher so gram-for-gram you get far, far less hydrogen produced so there's no appreciable explosion. It fizzles far less spectacularly than lithium, sodium or potassium. Brainiac faked their shots of it with conventional explosives. Both Mythbusters and Theodore Gray have good debunkings of the claimed caesium and rubidium reactivity.

  • Periodic table of videos and thunderf00t. Win!

  • I wonder if any of this has to do with spontaneous combustion.

  • can you come to my school and teach science please. im have the strangest feeling one of the teachers could take a NASTY tumble down the stairs if you say yes.

    (im only joking, about the teaching part, the teachers still getting pushed down the stairs)

    J.K.

  • To any youngsters contemplating studying chemistry at university after watching this video - DONT

  • @HeelofAchilles uh...why would you tell children not to pursue their interests?

  • @TheHigherVoltage Because im staring at hundreds of heteroaromatic mechanisms and its torture (im a chemisty undergrad)

  • @HeelofAchilles if it's torture, maybe you're in the wrong field :/

  • Watch your back. Remember Stan Meyer

  • If K+H₂O -> Evil then I can't imagine what horrors would be unleashed by Cs+H₂O.

  • More videos like this please Tf !!

  • My only question, Thunderf00t, is how do you know these are the first videos of this? High-speed capture videos have been around for a while now, one would think that one of those zany science shows where they blow stuff up all the time or some form of Discovery documentary would have done this for TV.

  • can I ask a really stupid question from looking at the comments?

    Here goes... What the fuck has a potassium reaction with water to do with religion?
