Alkali metals

[mapleleafswonderland]

fake and gay

[fredit10]

Mythbusters busted this

[iseeuder]

Frankee um

[4226emily]

Francium:

Highly dangerous

Very violent reactions with water

Very rare

Radioactive

[Xneroku]

Buy some of that, put in a water bottle, throw it in a school = WIN

[AndrosForever]

Sooo.. if someone was to swallow some of that metal.... ouch.

[stubbsrulez99]

Totally faked but still awesome.

[gumbykase]

@stubbsrulez99 Its actually one of the reasons this show got cancelled (much to my dismay)

That bathtub got screwed

[tobizgoodboy777]

hydromainiacs? XD

[nateDawg12346]

i now know what to go fishing with(:

[agro0]

Francium is extremely rare and radioactive, so I wouldn't recommend to blow it up ^^

[eric9898fullenerge]

f..k i can not imagine that somone foolish throw francium into the water........

[robotandlegolover]

mythbuster busted

[hikikomori14]

クレイジー！

[Cartoonsfantasycyx]

At 1.53 I think you can see a detonation wire. :D

[alienkilla22]

richard hamond epic scientist, shit blow uper extordinaire (lol).

[uux10mcu]

francium; highly radioactive, most isotopes have an extremely short alpha decay half-life. At any one time there is no more than an ounce of it in the earth's crust. Very clear reason it could not be obtained by the bbc for this program

[nisi2416]

how about Fr

[fairpride1201]

亀田先生ご紹介の動画はこちらでーす！

[UTubeisSHIT523441]

get over people, its fake. Brainacs admit that and mythbusters further prove, by dropping 10 times the amount of rubidium and caesium in the water, the explosion was not even 1/10 of the "big bang" shown here.

[eponaswings]

FAKE! 

[alienkilla22]

@eponaswings ey dick head richard hamond is a scientist and its an official video so y would it be fake cockhead

[IxImetal4lifeIxI]

not fake not fake not fake. I bet it's all the kids that aren't even in high school yet that believe everything the mythbusters say. have you ever seen potassium react with water? hint: take chemistry in high school and blow some shit up! we haven't done anything with cesium yet, but we might soon.

[FurkanKhan100]

francium is radioactive kids, so dont try

[ceasefire066]

imagine if the tub was closed!!

[Lionessfeather333]

How can you not like this?

[NB180]

Unfortunately fake.

[AssassinKai]

so fake! they did this on mythbusters and it epically failed! all it did was smoke.

[slaughtabal]

@AssassinKai they did sodium the least reactive, rubidium and cesium have close to 20-30 more electrons worth of force exploding. sodium does just smoke, lithium sparkles, potassium is like a fire cracker and cesium and rubidium well you saw..

[trackgurl881]

i watched this in chemistry because my awesome chemistry teacher decided this would be a fun treat

[sonic4132]

where can i find alkali metals in common household objects?

[EllPro]

Myth BUSTED.

[MrBeenis]

the last one was dynamite

[zacrainey1]

This explosion is fake, these explosions were clearly high explosive, such as c4 or a grenade. Whereas alkali metals are low speed explosives.

[jsmmtc]

@zacrainey1 your' re an idiot that obviously wasn't an explosive.

The gas accumulated then reacted with that explosion.

[thewiseowl]

@jsmmtc No, they are *clearly* high explosives. While the alkili metals are reactive, the amount of hydrogen produced from those 5g ampoules of metal just wouldn't have that effect. Not a chance.

[analychemist]

@thewiseowl

Actually no, it's not high explosives. Cesium and Rubidium are very exothermic and can generate enough heat to create large explosions. Sodium and Lithium don't generate enough heat for large explosions but as reactivity increases, the amout of heat released also increases.

[thewiseowl]

@analychemist Wrong on all counts. The molar enthalpy change for these process doesn't follow the expected pattern down the group, infact Li produces the most exothermic reaction. In addition going down the group there will be less hydrogen gas produced for the same mass of metal, and explosions aren't generated by 'generation of heat' but by expansion of gas. Also I'd like to point out that Brainiac was the 'tabloid mag' of science progs, twisting the truth just for a good story...

[JChan1026]

hmmm.....if they tested Francium,

I suppose the whole England would be blasted into bits =S

[YottaFlop]

Nerds porn!

[TheCarl98345]

richard hammond!

[jpepperman95]

Mythbusters proved this exact video as "Busted". Cesium and rubidium simply aren't that reactive

[Rulymiscreant1]

i love the idea of making chemistry exciting but still, at least make it real chemistry

[duanep1963]

mythbusters proved these guys are flipping liars 

[rhymeswithapple]

Was that the guy from top gear?

[Nikolaslimao]

@rhymeswithapple Yup!

[germangman1]

This is fake its been proven countless times again and again...

[NightslayersEntry]

Fake as hell.

[alexzhang101]

put a piece of universal indicator paper to see if that's real

[syedjaafar]

wtf?

[jadedmastermind]

Fake. Lead is the highest element in the periodic table with stable isotopes. All elements above lead are unstable (radioactive). The most stable isotope of Francium has a half life of only 21.8 minutes. Only about one ounce of Francium exists in all of the earth's crust at any given moment. If you had an ounce of Francium in your hand, you'd be dead by now due to its extreme radioactivity.

[kawana87]

@jadedmastermind unless you're Chuck Norris. He eats a big bowl of Francio's every morning :)

[CODxElevators]

@SirrVendetta' yes he says thats the dogs nuts, like in America people say "ohh thats tits" for something being awesome. Over in England they say "thats the dogs nuts" for something thats awesome.

[louish2]

Mythbusters failed at this because the metals were not completely submerged. They only had the reaction on the surface of the water. Busted my azz :/

[SirrVendetta]

0:51 does he say dogs nuts?

]

[afirocs]

how do you mythbusters isnt fake?

[TheLife0fBen]

this isn't mythbusters and it is real, these alkali metals are so reactive and are wanting to give away one electron so badly that when they react with water, H20, they will produce dramatic results

[dragonridley]

@TheLife0fBen

It was indeed faked. I have seen several videos that put cesium in water, none of the explosions were anywhere near that big.

Braniac also admitted to "enhancing" the reaction with explosives.

[chipmonkei]

@dragonridley it was indeed not faked, the videos you saw were probably different concentrations of the element, or the ratio of alkali metal to water could have been different, but that amount of metal in that amount of water would have obvious explosive effects as shown

[dragonridley]

@chipmonkei

Yes, the reaction is explosive, but not nearly as explosive as this for the amount of metal used. One group, which makes documentaries on chemistry, used more than twice the amount of cesium but did not get an explosion nearly as big. If you look just about anywhere you'll find it stated over and over again by respected sources that this was faked.

[TheLife0fBen]

the two in the tub are illegal to buy even because of how reactive they are.

[wigyjigyjig]

It's completely true smart ppl. Y don't u learn something about these elements. Obviously u had a bad science teacher

[Blacklemon67]

lol francium is radioactive :P

[saiboy92]

@Blacklemon67 Francium isn't radioactive, it is MUCH to reactive to other elements to be radioactive, that is why you cant find it in pure form in nature.

Reactive and Radioactive are two totally different things.

[dragonridley]

Francium is indeed radioactive. Yes, being an Alkali metal it is extremely reactive, but francium also has the shortest half life of any naturally occurring element.

[saiboy92]

Sorry, yes you are right it is radioactive.

[Nick100895]

@dragonridley

Francium also has the lowest electronegativety rating of any element.

[ma0ma0ma0]

fake

[akathecrash]

you are obviously in like grade 3 because if you have taken chem in high school you would know that all alkali metals react with water

[ma0ma0ma0]

yeah they are not strong enough to blow up a tub. they proved it was fake anyways you can see the wire coming out of the tub. they used c4

[MrIdontmakevids]

Your stupid. Honestly u must be in grade 2 coz in high school the chem teachers tell students about this stuff and it is true. Ever heard of the periodic table? Or alkali metals? Or even Chemistry? SO dont go calling it fake b4 u retards evn know wtf it is.

[ma0ma0ma0]

@MrIdontmakevids it was proved fake you fucking idiot, watch mythbusters. they do a test and the reaction isn't close to as strong as this. it is a piece of c4 or something. i know what alkali metals are, and i haven't even taken chemistry yet. so why don't you not call people retards when you're wrong.

[KinekaiNHFan]

i say¿w it on mythbuster, they try it OVER the water, for seeing if the "contact" with water on a tub can explote it, and it was fake, but not the fact that it reacts explosivly with H2O, and then they threw 2,5k of alkali metals on a tub! An even then, it was fake. Maybe to brake the tub, but not explode it. It's obviously that theese videos aren't true and they don't show you the whole procedure as Mythbusters does...

Anyway good BOOM xD

[volvagia333]

i would really like to see francium

[slaughtabal]

@volvagia333 francium is rumored to have the explosiveness of a small missile!! (almost 2 times larger than cesium!!)

[HappyDaysRUs1]

@volvagia333 something like 5 grams of its pure element exists in the world :/ to rare for blowing up

[YEUHNBD]

@volvagia333 if there was any left on earth..

[FFGFMENDOZA]

LOL ''these next two are the DOGS NUTS'' LMFAO!

[CptGrunt1227]

Boom goes the bathtub!!

My science teacher showed us this!! It's awesome!!

[Foebane72]

This TV programme is for morons. The Open University video on Alkali Metals is far more entertaining AND under proper strict lab conditions

[Udilator]

rubidum may not have that kind of effect, but it still have a violent reaction with water.

[gollen97]

on mythbusters they test it , it's fake..

[TheWickerIron]

If you know a little of chemestry it's not a fake

[gollen97]

dosen't mythbusters prove it wrong?

[xxFace2faceXx]

the myth that it could explode a wall is fake.... not the fact that it explodes....

[jagjit2k7]

hello 10s2 :D:D:D

[Rubensitoc]

we watched it in the chemistry lesson, was quite funny!!!

[mwahisgoed]

lol fancium i can understand that:P

[LucasA753]

2:30 look at the wire :P

[GYIKmaster]

This is a fucking forgery! 1:53 The electric wire, which goes into the tub, shows.

They set off a traditional explosive with that electric wire.

The alkaline metals they may not detonate this size! Too small they are in contact with the water on the surface!

The reaction occurs on the surface. But the arising gases or steams remove the water. Much time passes while the water may respond to new one with the alkaline metal.

[GYIKmaster]

2:04 the adhesive tape shows on the bottom of the tub. They fixed the explosive with this.

The braniac an idiotic tale, for idiotic children who believe it.

[f3llah1n]

Will you Yanks ever learn to tell the difference between educational and entertainment.

Next you'll be complaining about all the set-ups on Top Gear.

[cypheranarchist]

Yup, its faked. There have been news stories about how this program rigged a fake because the actual reaction wasn't impressive enough. In reality, caesium + water just makes a loud pop and releases some gas, definitely not strong enough to blow a bathtub apart.

[fisheater12]

this is fake guys but still amazingly enjoyable!!

potassium doesn't explode like that when mixed with water....and neither does rubidium or cesium

francium HOWEVER would be pretty nasty, and most likely send glass into the face of any close witnesses if it was placed in a vile filled with water

[TipTopDee101]

maybe cos they are in a solid form just like a exploding sodium in water

[fisheater12]

ya but the sodium and lithium reacted in this video just like they do normally

why would they change any conditions to test rubidium and cesium

i'm absolutely sure it is fake

[LucasA753]

It's no fake..

[marine12320]

It is fake... well at least the rubidium and caesium is. They did it for your entertainment...

[Woodzy1803]

wow, they completely forgot about the rubidium hydroxide and ceasium hydroxide. itll burn your lungs out, and its created when they do shit like this

[ferguson1010]

my bio teacher did the potasium shit lol

[CloneTrooper1703]

This bangs man !!! But when this guuy sais warning warning it takes another 10 seconds ... LOL :)

[xboxnissan]

You don't like your old bath ? Fill your bath with water and call them XD

[roycjame897]

i love you hammond

[AnimeFan22984]

nope brainiac lol forgot what channel its on tho =/

[AnimeFan22984]

is this maniacs?

[hnsolo77]

clearly science is for people who like to blow shit up

...

where do i sign up?

[bigdybadman]

cesium and rubidium are dogs nuts of the periodic table hahahaha! At 1:00 funny Brits

[avatarwanabee24]

hm i want some cesium now.

[SeanSaysWhat]

if there is any humidity in the air alkali metals can explode. They are highly sensitive

[Aff01000001]

Imagine giving a rubidium or a caesium capsule to someone =P

Or, at leat, imagine

[diazflac07]

loved this ep

[CreativeCritisizm]

What about those alkali lakes in California ?

[Bleezz]

those contain alkali salts, so those metals have already lost one electron and are not reactive with water. only pure lithium, sodium, potassium, rubidium, cesium and francium will react explosively with water.

[CreativeCritisizm]

Cheesy English production.

[CreativeCritisizm]

,,the 80s Kenny Loggins music.

[tonychiao]

In fact the blast was not the result of a meeting between water and rubidium

and caesium, but the triggering of a bomb

[petey65203]

come on .

[ice9fetus81]

so,here can i get those alkali metals?

[makotoh]

@2:39 The narrator says "as a Sodium sinks in the water, sth sth", but the Sodium does not sink in the water coz the density is lower than water. He should say "as a sodium swimming on the water,,,"

[Itachi6x]

This 100% real for those dumb asses who haven't taken chemistry or passed chemistry :D

[willy14916]

i'm taking it now and my teacher took us out into the grounds and actually showed this exact experiment but with a huge bucket not a bathtub and it was pretty close to this, it was cool

[diu1so]

fake :)

[DrGmedicalexaminer]

the wire is the hose

[DrGmedicalexaminer]

REAL

[FideliBomBom]

Fake!?

[pauliogazzio]

what's with the cable coming out of each bath tub? =/

[deltaforce4563]

that would be called how the filled the tub paul

[pozeci67]

cesium very strong

[mrbeetle1234]

Hi Shahir

[mrbeetle1234]

Ello...=D

[mrbeetle1234]

Hello...Riversidians....Watch Brainiac =D....3/2 RAWKS =P

[mtlownage]

omg u loser gf

-rs ftw

[CrazedHippie]

HA HA. Mr tickle is a awesome name

[Greenflashgeek]

why is Richard Hammond on this show. I thought he was conducting Topgear

[rossy2by5]

he does both then

[liverpool619]

what is the name of the song at the beginning!!

[rossy2by5]

probably danger zone from top gun

[guinesspie]

01:53 you can see wires dipping into the bathtub, it was a controlled demolition, probably some low grade industrial explosive (blasting powder ect) not sure which. There was no way that was rubidium...

[jarangnme]

You're a retard. That is a crack in the tub.

[seggsygal2]

alkali metals can be very very violent coz they're extremely reactive. and with that amount of Rb, that explosion IS definitely possible

[BenjiV]

greeeeeaaaaaaaaaaaaaaaaat

[simba6320]

its the guy from Top Gear~!

[loggeryvnv]

They do produce some very violent reactions in water, but come on this is Brainiac :P It's a half-serious/half-comedy show, as anyone who has ever been to the Dr. Bunhead lectures will know. You can see the wires going to the charge in the bathtub for gods sake. But you still wouldn't want to be near 2 grams of caesium when it's dropped in water :P

[ammosmoke]

I highly doubt this video was faked. Look up rubidium and water on google and see what comes up.

[Cr4zyD4n93]

Brainiac is funny :-)

[NVanWendy]

Gotta love Brit shows where they can say things like "the dog's nuts." Oh, and the explosions were cool, too.

[nanita134242]

OMG If i show this video to ma chemestry teacher he wouldd be REALL likk happy bou it cuz he luvbz thiz thingz =] but itz real ckoo n e wyz

[TheElvenChild]

this is SOOOOOOO COOOOOOOL!!!!!!

[Greenhorn82]

Just so everyone knows, this video was faked. A guy who worked for the show admitted it, and besides that, the fact is that what you saw is impossible. Cesium and rubidium simply do NOT do that. There are other videos on YouTube that show what they REALLy do in water. Also, you can to to Theodore Gray's website and find his "Brainiac Fiasco" article, which is complete with real videos of the metals.

[Greenhorn82]

Also, in Theodore Gray's videos, he used 5 grams, while in this video they supposedly only used 2 grams. Gray's explosion didn't even destroy the glass bowl.

This video is FAKE. Get over it.

[OnTheRun167]

And doctors prescribe lithium to people... Hmmm...

[RatkoUSA]

That's lithium carbonate, OnTheRun167, not pure lithium metal.

[Greenhorn82]

And OMG, you put SODIUM on food!

Oh wait, that's sodium chloride.

[clicks1058]

lol and you sucked on a lithium battery when you were a baby you fuck-tard

[KIllbox44]

its possible everthing in thr is real because first of all the big combustion or explosion is from the extremely dangerous rate of spilting to bases which in this case is 2H2 and O2 H2O and francium or any metal in the first group can do this because francium immediatly split the O2 from the hydrogen and it combusts of, of the H as fuel because of this the big explosion occurs and personally no offense to anybody but those 2 guys r dumb head francium and cesium are extremely expensiv

[elvis221]

seeing cool things like this make me wanna destroy my bath-tub

[ditachi07]

i actually did this in chemisty class also, when the metal touches the water it creates hydrogen which builds up and the metal will spark causing an explosion, the water after the reaction turns into an acid, very fun to watch

[wyz85]

wouldn't that mean that they let around 100L of acid in the environment without neutralising it? irresponsible one might say...

[ditachi07]

it wasn't 100L it was much smaller scale, and they neutralized it after if formed

[ditachi07]

man i miss that show, Brainiac was awesome

[dammitpeterZE]

would batteries work for the alkaline and the lithium?

[zven001]

Nasty.

[UpsidedownHandshake]

What about Francium?

[MethemadmaninMPH]

francium is not possible, since it has a very short half-life. So if they want to test with francium, they have to make it there(which i don't think it's possible).

[Antharis79]

"Mag... nificent!" ^_^

[cant0think0of0a0name]

The reason that they have no Francium is that there is physically not enough of it on the earth... It changes to Astatine in lke 30 seconds =P

Good stuff though...

[kgomehater603]

I need to e-mail this to my science teacher. he's a pyro, which is awesome, and had us se if we could tell what gas was in a jar. it turned out to be just methane, so he asked us what would happen if we lit a match in it. me and my friend just grinned evily, and he struck aq match. AWAY from the jar. it was hillarious to see everyone's faces!!!!!

[hohf85]

dude,pyros are sweet

[Maxxxshop]

Can somebody tell me where to buy that stuff :-D? Give me 1 week and 100 pounds of it and the whole world will be mine.

[LATVIA53911]

I love chemistry from that time I was in first form

[grizzlypb]

FAKE
