Alkali metals in water, accurate!

[Kumajirou13]

I love science sometimes...

[ueberperson]

This is not fake.. I blew up my chemistry lab with Potassium nitrate which has similar components as Cesium but not as harsh. I blew up a few beakers and got expelled from school for a week.

[Laizeeemzer]

I watched this video in Science today :)

[RetardedHi5]

CESIUM DON'T FUCK AROUND!

[BlueManGroup10ROBLOX]

I shat nricks.

[dwinkinney37e]

I want this video on my TM100 phone.

[JimNoir1]

My god, caesium is spelt C-A-E-S-I-U-M. And before people start pointing out that I'm a grammar nazi I'm just stating it. Anyway my main point was that for everyone who keeps saying is the caesium reaction real, yes it is. And they did not do francium because it is rare, radioactive and decays. I hate to say this but please like this comment if you agree, so that idiots like the many in already shown below see it before they post more stupid comments questioning the content of this video.

[jerryshizzle123]

@JimNoir1 you're an idiot yourself and nobody's going to like your stupid comment.

[JimNoir1]

@jerryshizzle123 To be honest, if you read it I hate doing it anyway. So I'm not bothered if it's liked or not. And I can't really be an idiot if I'm right not can I? I mean, I'm not wrong, so instead of hating me for no reason at all why don't you actually think why I would post a comment like that.

[jerryshizzle123]

@JimNoir1 since you insist that you are so right:

1) the spelling "cesium" has been approved by IUPAC and is the one with which more people are familiar. it is by no means an incorrect spelling, and only a jingoistic asshole would try to argue otherwise.

2) aside from the stupidity of endorsing one in favor of the other, doing so would make you a spelling nazi, not a grammar nazi.

3) your comment wouldnt stop idiots from posting idiotic comments nor would they read it, so why bother.

[JimNoir1]

@jerryshizzle123

1) I said I didn't care about the spelling anyway. So yeah I'm sorry about it, but I tend to go with the older spellings. Don't call me a jingoistic asshole, I said I didn't care and it wasn't the point.

2) No, because a grammar nazi is the correct term for people who correct grammar and/or spelling. GET IT RIGHT. Look up grammar nazi on the urban dictionary if you don't agree! It's as good a place as any, and I'm pretty sure 1459 likes means I'm right.

[JimNoir1]

@jerryshizzle123 3. Lastly, I tend to want to try and fix things, it's a habit. It's better than just replying at comments I don't agree with to annoy them. So SORRY for posting about it because YOU don't like it you selfish asshole! Some people might want to actually know about ceasium and do look through the comments. If any comment here is pointless, it's YOURS.

[jerryshizzle123]

@JimNoir1 ok, so you got me on the grammar nazi thing; just shows the stupidity and unpredictability of modern english slang - that wasnt my point either. if you didnt care about the spelling, you wouldnt have brought it up, let alone felt the urge to spell it out letter by letter in caps. secondly, considering that those claiming the cesium reaction is fake constitute a negligible segment and are likely either trolls or too stupid to read, id say your efforts are both naive and in vain.

[JimNoir1]

@jerryshizzle123 You can't deem all english slang stupid because of that one term. And just because I didn't care about it doesn't mean I won't bring spelling up. It's a habit. And like I said before, not every comment will be a troll or a person who is too stupid to read, some actually will be people who want to know or will just be idiots who don't believe it because they don't know about it.

[JimNoir1]

@jerryshizzle123 There are people in the world who are like me and will want to know things and I like to tell them because I find it enjoyable telling people mroe about things. You don't need to point out that I make uneeded comments because you thinks so. So my efforts aren't naive and in vain! Half the time I actually do get people thanking me for what I've said! Stop trying to point out tham my comment was pointless when this entire arguement that you started is.

[RMX7777]

@dannymarashi. There is only about 1 ounce of francium in the entire crust of the earth. What you saw was something else. Even if you got a hold of a large amount of francium it would Lose half of its francium content in about 22 minuets, not to mention you would die from radiation, it's currently not possible to get even a small piece of francium.

[liquos]

I want to see them drop a brick of cesium into a pool.

[dannymarashi]

i wanna see francium ive seen it in the ocean but how bout here?

[Crunchsnap]

You have restored my faith in cesium...

[mayanightstar]

"let's try cesium..." thinking: oh god that's gonna be huge- "aaaaahhHH!!!!!!

[danagol1985]

To the uploader:

You seem to know your stuff, so I have a few questions for you:

1. Does magnesium react with water in a similar manner to the alkali metals?

2. Is magnesium soft enough to cut with a knife? - similar to the alkali metals.

From my knowledge, the answer to both questions is no.

However, several friends seem to think I am stupid for saying that magnesium does not react vigerously with water.

[JimNoir1]

@danagol1985 You are correct, the answer to both of those questions is no, and magnesium does not act vigerously with water. Only slowly unless in a powdered form. (Just going through comments)

[Rcrby525]

@206robert206 no.....you can't, in batteries it's just thin sheets rolled up and capped, plus those just store energy, not produce it.

[Demi923]

Yeah, Cesium is the most explosive because it can release energy the easiest.

[NickRambo123]

No francium? :(

[JimNoir1]

@NickRambo123 Far far too rare. Additionally it is radioactive! And it's most stable form lasts for 22 minutes before half of it becomes astatine.

[NickRambo123]

@JimNoir1 I thought it actually had a half life of 27 seconds or something

[Trollsnews]

we should all send letters to mythbusters that if you take a ton of cesium and drop it into lake nothing happens. They will have to try it and show us!

[Sevilou]

@Trollsnews LOL!

[theeviljester666]

@Trollsnews even better, drop a ton of francium in a lake, they'll be fucked

[tkdkadir]

where can I buy this shit, im planning to make a huge bomb in my garden jkjk

[tahu2247]

sodium is only more explosive in larger amounts, because it builds up H gas before igniting it. all alkali metals above Na react to quickly and violently to produce this effect, thus Cs, Rb, and K are more reactive than Na. just a bit of info in case you didn't know!

[cutiecateluvie]

Cool

[rosabellis]

1:45 I checked my Skype D:

[mentaltfladdrig]

KABOOOOM!

[reemanwells37f]

[animotoabuse]

Y'know, francium is radioactive, so if someone put THAT in water...

[VictimTwentyEight]

Cesium doesn't fuck around!

[wrnerd101]

i got to watch this up close in chemistry class last week :)

[Diamonddavej]

Notice the caesium explodes when underwater, it's not a hydrogen/oxygen explosion. The reaction is endothermic, it causes the caesium to first melt, it then explodes when it suddenly turns into caesium gas.

[SnakiToT666]

awsome

[killerdanny2009]

Clearly some people have never attended a Chemistry class or did basic science in school.

Yes Cesium does that, no Sodium doesn't react more violently than Cesium. Go to a science teacher in your school ask about a magical thing called the "Reactivity Series"... >_<

[Quintus468]

It's like cutting cheese. Explosive cheese.

[fonzierox56]

i wanna see francium, thats the one on the bottom

[Aslanx10]

@fonzierox56

Lol. Francium is the 2nd rarest element on earth! There is only 20-30 grams of it on the entire planet... Therefore not available for sale to the public. Besides, its radioactive.

[AeroFlameX]

2:16 "EXPLOSION!!!"

[15rockclimber]

Yes, the cesium one is real. Each alkali metal as you move down the periodic table becomes more reactive. So cesium is one of the most reactive elements. When any of the alkali metals react with water they produce an alkali metal ion, a hydroxide ion, and hydrogen gas, and also heat. Each reaction produced more heat and the whole thing can become explosive because the heat can ignite the hydrogen gas produced in the reaction.

[Aslanx10]

And then next is francium.... which causes all the water in the ocean to splash out ;]

[ilubeeyou]

THIS IS WHY YOUR FATHER LEFT US, CESIUM

THIS IS WHY WE CAN'T HAVE NICE THINGS.

[BrandonBlaze904]

caesium check time to kill some water creatures.

CAESIUM PLEASE

[ShadyLeprechaun93]

DAMN CESIUM CALM YOUR TITTIES

[himynameishelen]

I love that you can hear someone quietly whistle after the dish breaks

[phantomXofXtheXMCR]

Cesium, calm your shit and stop being such a fucking diva. Not everything is about you, now we have to get a new bowl.

[AdrianBandic]

I'm laughing so hard with the cesium explosion XDDDD

[lalamei00]

oh god the last one why am i laughing fdjklsa;fdsa

[Xenakeyblademaster]

@kansterstrak

Correction. There's only 13 grams left.

[Shuki362]

u hear the whistle at the end wen it exploads lol

[mapleworld777]

Francium is radioactive..apart from the fact that its very rare its also very harmful to be near it

[nishantp29]

Seriously, majority does not determine science does it? Facts and UNTAMPERED experiments do.

[ironnica]

@nishantp29 aye, but when will you ever believe anything? It is good to be inquisitive, but dont spam this video or another that I post (made by a very prestigious Professor and his team) saying that you still dont believe. Anyway, check up with the Royal Society of Chemistry, they have something on cesium alone. Sorry, but nobody is going to bring this experiment to your house just so you can believe it

[insanitytruth]

You could hear someone whistling at the end =P

[TheMorelemonpledge]

Was the caesium one real?

[ironnica]

@TheMorelemonpledge right, try this one: watch?v=5aD6HwUE2c0

believe it now?

[kansterstrak]

Francium is very rare, only 25 gram exists naturally, so it's impossible to test how it reacts.

[INYO121277]

i wonder how francium looks like when it react to water..

If i was a school deliquent, i'll stole this babies on my chemistry lab, then throw it to the ditch while speeding on a motorcycle :D

[xCrumbleToBits]

LOL a whistle at the end *v*

[nishantp29]

Link

[nishantp29]

See this link:

[nishantp29]

According to popular science magazine, sodium reacts most explosively with water. Caesium however is not as explosive. I suspect they have used some dynamite or something to show greater explosion. False advertising asses!

[ironnica]

@nishantp29 watch?v=5aD6HwUE2c0

Look at that before you start shooting your mouth off. stay in school.

[Gunsand42]

@nishantp29 little children should stay in school instead of spamming useless comments. all alkali metals react violently with water (as you can clearly see here) sodium is nothing compared to potassium and even the most violent francium which if take into air for more than a minute could possibly explode cesium is an alkali metal alkali metal mixed with water will give off hydrogen gas

[JimNoir1]

@nishantp29 Not a very good science magazine is it then?

[GILLIGAN1080]

you don't see francium because it blew up the whole room. luckily the tape was recovered from the first few

[dawgsnsuch]

they never did francium....

[netaeta]

cesium wins

[19andoverlol]

Not only is Francium hard to collect, it's also radioactive. It's dangerous to be around, and it only stays as Francium for a limited time before the radiation it emits turns it into another metal which doesn't react with water.

[wheresmycookie2196]

What about Francium LMAO xD

[MKT227H]

WTH, the hand looks so bloody at the end!!!

[DjWeezyFBoy]

Wheres FRANCIUM ??? :p

[MrExelta]

@DjWeezyFBoy There's only about 20-30 grams of Francium in the earth's crust at one time. Gathering enough to make an explosion of this size would be very hard to do.. and very expensive.

[DjWeezyFBoy]

@MrExelta Yea I know......I just was Kidding....bro :P

[IsaraiLee]

Ultimate pop rocks?

[denelson83]

It seems cesium sinks in water, given that it's so dense.

[NotAffable]

@denelson83 Yes, it will sink because of its density but it cannot sink because it will react instantly with water. In this video, however, Caesium sank instead of reacting with water instantly like Rubidium.This is because Caesium is highly reactive and will form a layer of oxide very quickly when exposed to the air. This layer of oxide prevents the Caesium from reacting instantly upon contact with water. If Caesium sinks because it was very dense, then Rubidium should have sank too.

[iStrawHat07]

OMG THATS AWSOME

[MackerLiverpool]

how does moisture in the air not have an effect?

[cavedweller2000]

I remember watching this video in chemistry class 10 years ago!

[SemperFeared]

They reason they don't use francium because it is too reactive to hold, is illegal to obtain, and is extremely rare.

[Imphipis]

When they cut the metal why do I have this huge urge to eat those metals?

[Prokills95]

@Imphipis Because they look so soft and tasty ;)

[EnragedSephiroth]

@Imphipis Because they look soft and chewable? :I

[stuflikethis]

if i could only time it to put in someones drink i dont like

[lethrneck4]

i remember my science teacher in 9th grade asking us, can water catch fire, we thought he was nuts, til he did this very demonstration with some potassium!

[Shunnabunich]

Voiceover: "Let's try cesium, our fifth alkali metal."

Cesium: "Oh fuck that, I'M OUTTA HERE"

[qudratzazai]

@Shunnabunich how about you try francium? 

[FrankBeauchesne]

my science teacher show us that in class :P

[JustPlayTheGameNOW]

@timlin1111 its illegal and super dangerous and jar to get lots of lol learned in science class today

[timlin1111]

why not try francium? :D

[emo182kidd]

@timlin1111 to reactive/unstable to even handle or get your hand on

[EntrE01]

that was fun :D

I feel like this is still accurate enough for a basic idea!

[Unintelligenda]

Press 1 repeatedly "cubey cum coated"

[Gingerfacer]

You can see things become more terrifying as we go down the group...

[llsrx]

Whoa! I remember seeing this video at school ten years ago. I thought these things were kept in dusty science departments next to piles of 1970s textbooks: how the hell did you get a hold of it?!

[TheAnonymousSeeker]

Freaking AWESOME!

[TheLaughingMan0603]

they don't show francium because a miniball of that was the thing the americans thrown at nagasaky bay in 1945

[thunderfirebolt]

@TheLaughingMan0603 US dropped Plutonium, not Francium. Also, Francium has yet to be dumped in water because it is rare, radioactive and has a short half-life, so they don't have enough of it to just throw into water. However, it's reaction would probably be very similar to Caesium's.

[TheLaughingMan0603]

@thunderfirebolt god... some people just can't understand jokes, and they try very hard!

[pyrochemists]

if ever someone did this test with francium, no doubt it would be seen through a camera, behind lead shielding

[TrillionGrams]

YES!!!

[lastxp415]

they look like butter when cut. can i eat it? =3

[TheLaughingMan0603]

@lastxp415 sure you can eat it, but say bye bye to your chin when it touch the spit.

[XxPl4typusxX]

where's the francium? o.O

[I3L4NK]

@XxPl4typusxX Too dangerous to test.

[XxPl4typusxX]

@I3L4NK I know I know aha. It's also a very rare metal thats hard to get a hold of.

[Bamananatic]

Imagine dropping a ton of Cesium into a lake. That would be a blast. Quite literally.

[shiznak55]

who needs electrolysis...

[91honan]

I want francium. :(

[HELLo5170]

makes me wanna slice some francium

[moralabsolutism]

@HELLo5170 francium is highly reactive, i've never seen anyone try to react it with anything. Most likely because it is TOO reactive

[ParkourSyah]

1:22 that's how sperms searching for an ovum...

[jjmore12]

20lbs of cesium and  3 gallons of water please :]

[giuliodice1]

Vsauce anyone

[opaz79]

This is why they should search uranus when you exit the classroom to prevent dangerous terrorism. They should search all students anuses regardless of class or study so it wouldnt be discriminatory. We dont want to be pointing fingers and making people feel uncomfortable unless it is completely necessary.

[Kawarukia]

Well that was awesome.

[AnemoneTrance]

Lithium creates a firework type-thing and then cesium just explodes that is so cool!

[singx08]

i most liked the whistle at the end when cesium raped the water. :)

[onlyplastik]

I remember watching this in school too. After Cesium, I expected him to say "and now, francium" and for everyone to say "NOO!", the a shot of someone dropping it in the water, then a mushroom cloud.

[shrikedecil]

100% Awesome.

[aukondk]

I vividly remember watching this in school, the cesium reaction in particular!

[Quiras2]

"Let's try Cesium our fifth alkaline metal" Boom! Glass basin breaks. Silence. I'll bet the even those students at the back are awake now.

[UmGarfGarf]

lmao, you can hear a guy whistle right at the end after the glass breaks

[blaixx992]

@Calgarylames theres not enough in the world to waste on stuff like this

[NikaziO14]

@Calgarylames Francium is a trace element and only exists as a pure element for a few seconds
