  • @PurplePhury3412 ;P i was just goshing i was hoping someone caught that

  • guys it really is simple... if there was a real alkaline metal reaction that powerful... there wouldnt be water coming out because the reaction uses the water as one of its reactants.

  • you do realize that the amounts shown in the "real reaction" videos are about 20x smaller than the ones in the braniac video? they are specks. They use something like 20 g rubidium and cesium in the vid and in the other vids they use about 1 g...just want to point that out.

  • because there just HAPPENS to be a wire hanging out of the bathtub...

  • Yes even if it is fake.

    Go down to your nearest chemical supplier and tell them you want 2g of rhubidium and caesium to blow up a bathtub and see what they say in return.

    The point of it is to convey that higher metals with a valency of 1 have a higher reactivity and...having fun blowing up bathtubs. :)

  • @N7SpectreLT of course it is. I do enjoy watching huge explosions, I'm not going to lie. But the fact that so many people think this is real (more specifically them being complete retards bitching at people and claiming to know it for sure "because the internet says so") really bugs me. Yes, it pisses me off. I had to point out that this is fake... and I expected it to get alot of views, which it did, for my measures.

  • @sciencoking If you knew anything about explosions, you would know that when completely surround by water, an explosion is usually reduced BUT...when the explosive is set off next to something (i.e the bottom of a bathtub) the explosion is concentrated to that point. thus why your demonstration is inaccurate to the braniac version. Another reason is that the rhobidium you used was exposed BEFORE it hit the water, so a lot of it was dissolved in oxygen before it hit the water.

  • @N7SpectreLT Yeh this video is real, i study chemistry at uni and this is exactly how alkali metals reat with water. Admittedly braniac often skews some of the experiments to make for a etter programe but this is true.

  • these reactions arent fake.. if u look at the reactivity series u will see that Rb (rubidium) and Cs (ceasium) are at the top which means they are extremely reactive and u have to be extremely careful. so brainiac aint fake its all real. i know this especially as im doing GCSE chemistry and also my mum is a fully qualifyied chemistry teacher

  • @eevelutionsfan Then i pity your teacher, adn the students of you mother......

  • @necos dude i pity u for not getting a decent education + My mum is a very good chemistry teacher she made me get the highest in my year in the chemistry module if u dont believe me screw u. i would have never passed with out her help. i got an a* . let me guess yr one of the fellas who's got nothing better to do but just make fun of ppl cause they have no gcse's right?

  • @eevelutionsfan No, i am one of the guys who get A in university chemistry and acctually know how it works. Unlike you and your mother

  • @necos yea sure u did... my mum got A's inb chemy + bio and she is a fully qualifyied teacher who is able to teach. my mum passed her degrees with flying colours, now please i dont wanna fight with some teen who thinks he's so smart , yr just stupid

  • @eevelutionsfan Getting A's, while still thinking this experiment is real. Kinda makes me feel sad for the university that graduated her aswell.... 

  • I love how both Cesium reactions made smoke at different scales... And he asks "where did the smoke come from???" -.-

  • So whatever. Even if it is fake the explosions are still cool

  • @PurplePhury3412 If they wanted to make cool expltions, why not just use tnt? or even ethanol like they do on tv :)

  • @necos Because blowing up TNT doesn't prove anything. I learnt that I'd be stupid to make waterproof stuff by covering it in Cesium.

    @l337tub Thats like saying TNT wont blow up peanuts because, belive it or not, they're one of the ingredients of TNT

  • @PurplePhury3412 This doesn't fucking prove anything either. If your wanted to waterproof anything. Covering it with cesium would do nothing btw. It would not be dangerous, because it would SLOWLY react with the water in the air making it harmless.

    Also. I once watched a guy who blew up a mountain with a piece of paper. Now i learned that you shuold not bring paper to the mountain because then the mountain would blow up INSTANTLY. Wow i feel smart after i learned that,...

  • @necos Let me see this paper blowing up a mountain.

    Also, In my science class the proffesser coated potassium with water and it exploded. I already knew that cesium is stronger than potassium, so I think that Real life > Something a guy off the internet said without any proof.

  • Your missing two important things.

    1. The quantity of metal used in the tub is probably bigger than that in the lab in the clips you showed.

    2. They are not being 'thrown' in the water. They are put in tubes that sink to the bottom and settle there for a few seconds before going off. The release of hydrogen will be under high pressure that throws water in all directions. It cannot burn until exposed to air, by then it would have expanded. Only H2 that is close to Cs will be purple, rest yellow.

  • @XtQfH 1. I even added an annotation in the video which points out that they say they're using two grams of rubidium.

    2. The heat from the reaction of the caesium with the water creates enough heat to procude some water vapor carrying caesium ions, making the flame from the explosion purple.

    Besides, a lot of more serious youtube users (like the official channel of the university of Nottingham) have re-done the experiment and they all came to the conclusion that the Brainiac clip is a fake.

  • @sciencoking Ok I looked at again. I missed the 2g part (don't see annotations on my iPhone). And I found something on badscience that says theyre fake. I guess you are right. Have an upvote!

  • @XtQfH Thank you :-)

  • the only interesting part of this video is the girl holding up the lithium sign lol

  • At my school in Gr. 9 science we put Sodium and Potassium in water we also blow something up on fire nearly twice a week!

  • hmmm. Frankium?

  • @DTHAtrain137 franconium is radioactive, and the most reactive metal, which is why they can't do it. plus, there's only about one kilogram of it in the entire world.

  • My chemistry teacher reckons they used explosives. So do mythbusters even when they used stupidly high quantities like dropping bricks of the stuff. Didn't create an explosion anywhere near that. Also with the small quantities of the metals they are using why use a bathtub the water is still going to be in excess like when it was in the see-through bowl only now you cant see inside.

  • I think that they are too scared to put Rb and Cs in water

  • Comment removed

  • we watched this video in my chem 105 class today

  • who WOULDN'T like to make BATHTUBS AND YELLOW PEOPLE GO BOOOOOM?!?!

  • haha you should join mythbusters! :P

  • I want to actually try to put a depth charge in a bathtub now.

  • Sorry one last thing, question: How much rubidium was used in your example? Was it the same exact amount?

  • PS: that so called "black cable" is actually called a CRACK

  • all of this is true. you should really do more research before posting scientific information as fake because when your wrong it makes you seem reeeal dumb. But as i said before everything in this video is REAL.

  • how can teachers in America, UK or wherever you are from show you reactions of cesium and rubidium, unless they´re crazy. What about safety of students or pupils??? So irresponsible. And sorry for spelling mistakes, I´m from Slovenia.

    Not Slovakia!!! SLOVENIA.

  • @15klmn its illegal to use cesium and rubidium here in northern ireland

  • I formally apologize for my rudeness sciencecoking. I have learned from a reliable source that this really IS a fake. Sorry.

    SOURCE - "The Elements" by Theodore Gray. A legitimate book.

  • Damn conspiracy theorists...

  • Fun spoiler.

  • Oh wow, look at that shit, the Cs reaction YOU showed after the Brainiac video has fucking smoke too, wow you're stupid

  • Good Lord, I'm finished watching the video and do you know what smoke even is? Put K in water and bam, that shit smokes too, just because it has smoke doesn't mean traditional explosives were used. Yall got seriously trolled by the poster

  • The poster of this video is obviously a moron, the Rb in the tub was under the water. That = water being displaced instead of air as seen in the "real Rb test" shown after Brainiac's tub version, also I'm pretty damn sure the little amount of Rb dropped into the dish wasn't 2g's

  • Whats the song in between the clips? like at 1:53 Thanks

  • @Halflifefan54 it's actually a sample I copied from this video: pGeWBiLVn8g

    That also explains the "woosh"... Unfortunately, I have no idea if this is even an actual song... I wish it was, because I like it too. I'll let you know if I find it! If you find it first, tell me :-)

  • Comment removed

  • @sciencoking lmao, I knew it was from that video! I remember watching it like 3 years ago, and I've been searching for that song ever since... thanks though, and nice video, I don't really understand why it has so many dislikes..

  • Thats isn't a fake

  • And I would've gotten away with it had it not been for you meddling kids... Why do u care about it so much columbo

  • ...my ap chem teacher showed us this in class... and according to him, this is actually very accurate.

  • @xxAlicepuppet your chem teacher sucks. I guess people on here won't shut up until I actually do it myself and hell I'd do if I had the money.

  • i like mythbusters better.

  • I'm going to overlook the fact that they didnt do an "apples to apples" comparison by using an equivalent amount of each metal. It is sad how you even have to look at these types of "science" programs with a high degree of skepticism. These types or programs are supposed to generate enthusiasm about science but do they really have to resort to out right fabrications for the sake of a glorified demonstration? Way to betray your audience while insulting their intelligence. What a shame.

  • @leptonsoup337 Brainiac isn't a science programme. It's an entertainment program that uses science as entertainment.

    Have you ever watched a full episode? It's fun to watch, but anyone with some common sense can see that it's not all real.

  • No one is doubting whether the alkaline metals Rubidium and Cesium will cause a violent and dangerous reaction when mixed with water. But the explosions in the Brainiac video are faked. An acute observer will notice a fundamental difference between the real reactions and the explosions in this video. A real reaction produces a flame, a lot of white smoke/gas, some water splatter. The explosions blow the water and the tub and don't have the flame/smoke.

  • Would it have worked if they'd had a Kg of Caesium?

  • @ajuk1 It wouldn't work even if they had 2 Kg of cesium. You really should watch the Mythbusters episode where they test this. It causes an extremely violent reaction capable of cracking a bathtub, but it certainly does not blow it to pieces.

  • @ajuk1 but the wires prooved that they were connected to something inside the tub(that's some explosives).

  • Thunderf00t

  • @Arghira

    Sciencoking - Oct 14, 2008

    Thunderf00t - 2011...

    Arghira - idiot

  • There's plenty of videos of youtube showing caesium and rubidium exploding in water, are they all fake?

  • Comment removed

  • @adjam1991 that's not true, sodium does catch fire sometimes and potassium tends to explode indeed. I bet they did a few dozen takes though.

  • @sciencoking correction sodium catches fire all the time, unless u use a very very small amount

  • @adjam1991 Sodium does give a flame and pottasium does explode, we did it in school today, its not fake.

  • @adjam1991 lol im afraid you broke one of the many rules of science. a single experiment proves nothing, try repeatedly and you will eventually get the drastic effect that is sodium catching fire or potassium imploding.

  • Heres a thought. Why don't you just simply learn from the video instead of debunking dumb shit. Whether its fake or not, I know not to mix alkali metals with water. That is all the video intended to teach you. Btw, from what I remember, rapid expansion of gas thinned the atmosphere around the explosion allowing more light from the sun to pass through, which happens to be yellow. So there.

  • @MAjormozes It is not learning though, it is lies. What its really is teaching you is not to put real explosives into water and detonate them. And the creater of this video is correct, the show faked this. The reasoning behind the faking of blowing up a bathtub is because it costs pennys with explosives, Doing it with alkali metals would cost 10s of 1000s of pounds. The amount of ceisium they claim to use, would not even be enough to make water splosh out the top.

  • @MAjormozes Also sunlight is not yellow, it is white. High school science is not taught by scientists, it is taught by teachers that don't have a clue.

  • @MAjormozes Oh and finally, and explosion is a high pressure wave, not an area of thin atmosphere

  • In answer to "where did all this smoke come from???" you will find that in the videos that you added, after the reaction there was some "smoke" coming from the glass bowl

  • Sorry. Don't buy your claim.

    The video you provided for comparison uses *significantly* less cesium; and the reaction was significantly less violent. The 'smoke' is not smoke at all. Perhaps next you'll explain why 'Ivy Mike' was fake, because neutrons, beryllium, and krypton are not white.

    If one pays close attention, you can see shortly after the 'yellow' that there is a very light, and brief, color change.

    Or, to put it another way: Where are you cesium videos?

  • @jody4403363881 The reason why he has no cesium vids is because a gram of cesium is worth a grand.

  • what a trash video. The explosion is under the water so the water is going to fly up in the air like your head in the clouds. Can you not see they use much more caesium than your example.

  • Umm, On the Rhubidium one, bear in mind the rubidium in the clip reacted at the surface, the rhubium on braniac was fully submerged, so no parts of it flew off, as it exploded it kept hitting water creating the hydrogen, rapidly, under pressure with heat.

    As for the orange flash, it looked to me like an automatic digital correction of a large blue tint on a frame but i'd need to get the footage to be sure on that.

  • @SPACKlick

    brainiac did fake it, the amount of hydrogen produced by these 2 grams can in no way explain that kind of explosion, its just not possible. the first reactions are legit, rubidium and cesium are fake.

    by the way, they claimed to have been using a vial that somehow dissolves after a while. that doesnt exist, you get these metals either submerged under mineral oil, or in solid glass vials. so normally the experiment would involve first breaking the vial, then dropping it in.

  • Brainiac should of hid both cables so we could not see them. Especialy the big white one in front of the camera. I mean, who would not see that(apart from me the first time i watched this clip.)?

  • Cable is holding the bathtub down. The amount used in the bath tub was much larger than your example, and it was under the water. Quantum mechanics you don't want to explain? Give me a break. There is nothing fake about this, all Cesium explosions will look slightly different based on the situations given. The cesium blew under the water as oppose to on it in your example. This video is a waste of time, stop looking for things that aren't there

  • @sacr3

    And you have full proof of your point of view? The evidence in this video, I must say, as a chemist, is much more reliable.

  • @CalumAJM lol ure an idiot, the ammount of rubiduim is same on both experimients and the ammoutn fo watter doesnt matter, the second experimient is much more releaistic as braniac proably used explosive for mroe entertainment. plus rubidium and ceasium will never wait for someone to get to safety then start to react, itl go off as soon as it touches the oxygen as it reacts with oxygen and water.

  • @hatim178 you are an idiot because if you actually watched the video, the man clearly says the metal is encapsulated within a glass tube with argon gas inside. listening > you

  • Comment removed

  • I stopped as soon as you said quantum mechanics.

    Really now?

  • @logitech4873 Well, you can explain it with quamtum mechanics, but the important thing is that the emission spectrum of caesium looks blue.

  • @sciencoking

    When Cesium reacts with water, it spawns hydrogen, and instantly ignites it.

    Hydrogen makes a red / orange flame when it ignites, so I'd say that would explain the orange light.

    I've never watched Brainiac, nor do I really care whether or not they are legit, but that's what I assume.

    Also, I'd like that Quantum mechanics explanation.

  • @logitech4873 As I said a few days ago:

    "Emission spectra of atoms and molecules are determined by quantum mechanical effects"

    I can't give you the exact numbers (I'm not that much of a nerd) and all I was really referring to is the quantum mechanical background behind emission spectra. An electron in a caesium atom leaves its excited, high-energy orbital and enters one with a lower energy, the difference is emitted as light.

  • @sciencoking Can you please give us a detailed explanation. And please don´t think every youtuber is too stupid to get it! Obviously you are not the only one, who masters chemistry basics. ;)

  • @hexhecks23 Oh I don't. I know there are some really decent people out there.

    I'm starting to think you're trying to test me, which would make my answer kind of obsolete because nobody really wants to know it, but since at least that's a form of interest, here it goes:

  • @sciencoking Electrons of an atom are placed in orbitals around its nucleus. For understanding this, Bohr's model is sufficient / the orbital model is only more confusing.

    The shells of an atom can only hold a certain number of electrons. In ceasium, the number of electrons is such that after saturating all the lower shells with electrons, one is left, which is put into the highest / outermost shell. This electron is very far away from the nucleus, causing the electrostatic attraction [tbc]

  • @sciencoking by the nucleus to be really weak, which is why it can be removed from the atom so easily.

    Electrons can also be placed in higher shells, further away from the nucleus, in which case they would, just like planets around the sun, have a higher potential energy than in the optimal state. This "excited" state is somewhat stable, but after some 10^-8 seconds, the electrons usually fall back to the lowest shell available, losing their "potential energy".

  • @sciencoking the first law of themodynamics dictates that this energy has to go somewhere. On the large scale model, there is no solution to this problem, since a planet has nothing to give its orbital energy to. An electron, however, can simply emit energy in the form of light.

    The interesting and most important aspect now is this: Every atom has a different set of "shells"/orbitals, a different nuclear charge and thus different "distances" between the stable orbital of an electron

  • @sciencoking and excited ones. When an electron falls back to its lowest energy state, it emits a photon, This photon's energy is equal to the difference in energy of the two orbitals. These two videos explain this very well:

    R7OKPaKr5QM

    5z2ZfYVzefs

    Since the energies of each shell in different atoms are different, each element has its characteristic energies for its excited states, esulting in different energies emitted as the electrons re-enter their optimal state

  • @sciencoking ... resulting in distiguished emission spectra for each element.

    The emission spectrum of caesium happens to be dominated by blue photons, which is also why it is called caesium (caesius means light-blue, as far as I remember).

  • @logitech4873

    im the nerd you are looking for i think :)

    the presence of certain substances in the flame will change the color of the flame. read the article on wikipedia about "emission spectrum", and i can tell you that the method of adding metals to a flame works well with a hydrogen/oxygen flame.

    to go deeper, into quantum mechanics, read "Pauli exclusion principle" on WP. Its one of the 3 most important concepts in quantum mechanics.

  • @logitech4873

    ... second comment

    the pauli explusion principle explains, in combination with heisenbergs uncertainty principle, why atoms are so big (tiny core, even smaller electrons, lots of empty space), why rocks are hard and cannot pass through each other, absorption and emission spectrums, and lots of other things. It explains why white dwarves and neutron stars exist.

  • @kurtilein3

    Allright, I'm not completely sure if I understand, but thanks anyways.

  • if rubidium and caesium are the king and queen of the periodic table then that would make francium the god. well it would if it wasn't so radioactive. it's most stable isotope has a radioactive half life of about 22 minutes. that's not very long!

  • what the fuck this has to do with quantum mechanics?

  • @onouh Emission spectra of atoms and molecules are determined by quantum mechanical effects

  • @onouh

    on wikipedia, first read "emission spectrum", then read "pauli exclusion principle", which explains emission and absorption spectrums. the pauli exclusion principle is totally in the realm of quantum mechanics.

  • The points made in this video are correct. This website (which I take no credit for) gives a very good and accurate explanation of what happens as a result of reactions of alkali metals and water: theodoregray com/PeriodicTable/AlkaliBangs/

    All the debate is however pointless, Sky admitted years ago the explosions were faked, and those responsible were taken off the production team. (...)

  • (...) This was reported in major newspapers, and you can easily find the stories on the internet. A crew member has explained what really happened to the metals:

    “Absolutely bloody nothing. The density of caesium ensured it hit the bottom of the bath like a lead weight. The volume of water then drowned out the thermal shock. They could not go home empty-handed. So they rigged a bomb in the bottom of the bath.”

  • you dumb asshole, they used like 20 times as much as you did, obviously its less reactive

  • they cant lie, they get sued

  • Comment removed

  • Comment removed

  • @seedysong Instant cold packs. Chemical reaction. Heat?

  • @sciencoking aha , that's called an exothermic reaction.

  • @seedysong not all chemical reactions produce heat some becomes cold

  • @seedysong they also said they used 2 grams of each metal, so .023 moles of rubidium and .015 moles of cesium. the chemical formula at 5:02 is correct, so this would mean the amount of hydrogen gas produced would be .0115 moles and .0075 moles, respectively. please tell me how they could get that magnitude of an explosion with .0075 moles of hydrogen gas.

  • @outerspaceidiot someone who actually knows chemistry. Thank you.

  • @seedysong obviously you haven't seen it occur.

  • fuck it, explosions are explosions

  • you have an unfair argument on your hands here, the brainiac test uses a larger amount of the metals traped inside an argon vial and submerged in water, where as your so called science videos, use a smaller amount of the metals in oil and places so it will float on the surface of the water.

    the conculusion: unfair test .

  • @BlackIceDraco "your so called science videos"

    When did I call them "science videos"?

  • @BlackIceDraco Brainiac's Dr. Bunhead admitted it "... The density of caesium ensured it hit the bottom of the bath like a lead weight. The sheer volume of water then drowned out the thermal shock-wave I was expecting to shatter the bath. They could not go home empty handed. So they rigged a bomb in the bottom of the bath and then blew the shit out of it. I must say it did look cool ..."

  • @BlackIceDraco No, they used the SAME amount of rubidium. Also, I don't think you know this, but, whether a reaction occurs underwater or not, it releases the SAME amount of energy. It's only the dispersion of the energy that is changed, water being far denser than air, and absorbing more shock waves.

  • nuke the bath!!

  • They faked it look on wikipedia

  • My bad, It's not electron affinity, it's Ionization energy. EA is if from gaining electrons, not losing.

  • Look here. The reason Cs reacts the way it does is because it's farther away from H than the rest of the elements. the reason it explodes as so is because the outer most electron shell of Cs is so much father away from the nucleus than Na or K that the force required for it to lose electrons is not much because there is less attraction force from the protons. the farther away, the easier to lose electrons, the more energy released, therefore big boom Basic rules of Electron Affinity.

  • thats because they used a tub u retard

  • Comment removed

  • Rubidium and Caesium explosions were faked it is highly unlikely that they were able to get their hands on a fraction of that amount into their show. They are both found in compounds because they react so vigourously with water and air and must be kept in oil at all time and that is why they are never found as raw rubidium and caesium and it would cost and enourmous sum of money and frankly it is next to impossible to find any on earth.

  • @Calsaur So true. The substance in the test tubes might not even be Rubidium and Caesium to begin with.

  • @L3irus Thank You, I'm only 13 and I want to be a scientist.

  • lol Don't you learn Chemistry in Highschool!! lmao

  • it isnt fake my uncle showed me all the reactions in has labratory at exxon

  • Not busted, you have no proof, only speculation. In 16 inches of water you have room for more hydrogen to accumulate before the ignition and it is contained. All other videos I have seen drop a small sample exposed to the surface of the water and has no chance of sinking before it starts popping. Imagine igniting a small amount of gun powder on a table. it will not explode. Also, I didn't see any flame color at all, it was inside the tub, under water, so any reflection on the trailer..

  • fine just ruin one of my favorite shows as a kid

  • Accurate or not, this video is worth watching in its entirety for the phrases "Mr. Tickle, bring on the rubidium!" and "the dog's nuts of the periodic table."

  • the reaction was 'way less violent' because they used half a pea sized amount of rubidium, rather than a stick of it.

  • just about ure theory that 224ml never can blow up a tube. if the tube would be filled with air, true. but with water it's different. it's not about the weight ore the volume alone, its the speed of the gases traveling true thrue the water, with one word: Pressure.

    and the presure is enourmous. try to compress water by yourselve for about 224ml plus, this in about 0.2 sec. maybe than u can imagine the upcoming force of this explosion.

  • Look mate the brainiac test was under water while you exapmles were on the surface of the water so how the hell can you say it's fake, get your facts right.

  • @Rockygem23 One word: Mythbusters.

  • @sciencoking they only used sodium. where did all the smoke come from? 2:17 ... but whatever. everyone has a right to believe what they want to believe.

  • @sciencoking the mythbuster test was ontop of the water too. i have seen those 2 put in water with a way more power full explosion (more power than mythbusters explosion by a little) that actually blew up the beaker that it was in. did it irl in science class.

  • @sciencoking Mythbusters = Amaterism!

  • @sciencoking those are actually 2 words

  • @Rockygem23 Ahem. Your words already proves that you don't understand Chemistry.

  • @Rockygem23 Duh? There is no argument in the first place to begin with. They have already said it themselves that they faked it. And no, how much surface area are you going to say it's going to increase. Twice? Make it even x3 and the original still couldn't match up to what the brainiacs have shown.

    Not to mentioned that he had already proven his point by telling us about the colour of the flame.

  • @L3irus Under wow you're one over confident troll aren't you? Jeeze i see it's quite unrealistic but the whole point in the show is to get people intrested in science by lying.

    But if they did francium I would be similar to one of the fake one though... if done correctly.

    Don't be so angry I was just pulling your leg.

  • @Rockygem23 We don't even know anything about Francium yet. Plus, I don't think it would be that reactive because there are only slight changes with each descension.

    The other thing is, there are still people who still believes that Brainiacs are not lying even with all the evidence shown in this video.

  • @Rawrfac3 they won't rest until I do it myself.

  • Lol, but when you TRY HARD to prove something fake... get your facts straight. The K in this videos seemed to be less damaging then most other videos. But they also use a smaller amount then most people... The Rb is a HUGE amount used compared to other science videos and same with Cs. Which in "Science" terms means "Bigger boom".. Think about it, you dont want a small portion of ammonium nitrate to make a badass boom, you want a large amount that will decentegrate a bathtub. or is it just me lol

  • @supra1 Jon himself said it was two grams, which is definitely not much more than the amount used in "other scientific videos".

    Many professional chemists on youtube have done this experiment with much larger amounts than two grams of both rubidium and caesium and the reactions were always nothing compared to this.

    And you have to explain the word "decentagrate" to me.

  • @sciencoking

    It's the depth of the water. Water is heavy.. it has to lift an entire tub of water, or.. blow out the bottom of the fiberglass bathtub. Trust in this.. if you place caesium in an enclosed space.. especially if that enclose space offers no place for the expansion to take place.... watch your ass.

    You may want to remove this video as it shows you haven't really thought this through.

  • Okay, i thought, i know a lot about science but this is insane :)

    Really really good !

  • haha...boom :D

    who's your daddy?

  • Mythbusters just proved it's bullshit you dumb sheep.

  • You are completely wrong all those things can be explained

  • at 2:35 u can see Rubidium witch react with the water of the Air!!!!!

    not with the water in the glass!!

    at the Smoke on the last: U can see HOTWATER wich evaporated... the reaction is so hard so the water were very hot and 30% evaporated.

  • No I'm fairly certain that they didn't, two days ago in chemistry class my teacher blew up a 750mL beaker with a tiny piece of Na, the second least reactive alkali metal.

  • why would richard hammond lie to us

  • your right this is FAKE!!!! THEY PROVED IT FAKE ON MYTHBUSTERS!!!

  • you shot down your own smoke theory

    gj

  • Caesium wasn't fake on the "real" reactions there was only a tiny bit of purple but slot of White smoke. And you dont know how deep the water is so the CH2 might not of risen high enough for the camera to catch.

  • the rubidium they used in the other video was about 0.1 gram.

    But it may be faked :)

  • you seem to know a lot about science, but you cant spell caesium?

  • @iCal660 Both are correct. Get a dictionary.

  • White chord was obviously holding down the tub because you can see that that portion of the tub only tipped over. did they use explosives i don't doubt it but that white chord had nothing to do with it

  • this video is fake

    not the brainiac episode

    evidence: when the 2nd Cs reaction took place i saw a illumination similar to that of the trailer

    also the smoke from the cesium explosion is obviously escaping hydrogen

    so your video is FAKE
