  • i come here to see francium, but i see all the alkalin metals except francium.

  • Now THAT was Cool !!! --- (As well as interesting.)

  • I think they cheated by making the bit of Cs larger than the others.

    What is that item thrown into the vessel before the Cs sample?

  • The *real* reason you won't see francium in the lab: it's half-life is only 22 minutes. In the time it takes to smuggle it from Kazakhstan to the lab, all 0.0000000001 μg of it will have decayed into astatine.

    Also, I'm not buying the rubidium and cesium reactions. Google brainiac fiasco. Sensationalism is not science.

  • yurrrrrrrrrrrric

  • Lol nice vid

  • 400lb of cesium blows up the pond the francium blows you up

  • So Cesium martinis are out then?

  • the last

  • HAHA love the whistle someone does after the cesium explosion

    

  • Wow!!!!!! Still to bad they didn't show francium!

  • @weaslyisking Francium is so radioactiv. it's radioactiv half-life is only 21 minutes

    so you cannot get a amount of Francium to show an experiment like this.

  • @weaslyisking unless you have a nuclear reactor francium is a bit too expensive

  • guess they need a new bowl of water for the francium then...

  • because francium is used in laser atom traps its radioactive so you can't just find a piece of it

  • smoke on the water

    daow, daow daow daow

  • Only 1 kg of Fr is present in the Earth Crust. That's why.

  • No francium? :[

  • @TheLizGang You saw sat cesium did, imagine fracnium

  • Related videos: Rampage Jackson Dry Humps Reporter.

    ???

  • 0:32 - I checked my Skype...

  • Let's try Caesium...*ding*...WIN!

  • Wasn't Francium, cesium.

  • that narrator seemed calm when the explosion makes funny noises

  • francium is the must reactive known metal. imagine the desk being gone ane his hand and matbe parts of the back wall with a carrot stick size piece. but unfortunatlly the plant earth only has about 3 grams of it. somthing more exposive is ANTI-MATTER!!!!!!!!!!!!!!!!!!!­!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!­!!!!!!!!!!!!!!!

  • Love the whistle at the end!

  • death to grammer

  • @TheJFKWahoo and spelleng

  • Where the hell is Francium?

  • Nobody gets the most important part. It can only exist at all for 22 minutes before it decays into other elements. Never has any been isolated into a measurable quantity. Ever

  • Eh francium ain't thr it's impossible to even have it, maintain it it's a very unstable and as soon as its formed it just decomposes!

  • @TheGills12 Francium CAN actually be preserved, it's a metal. There are only about 6 elements that immediately decompose, and none are Francium.

  • @ilikepienotu I'm almost positive you haven't even come into contact with said Francium metal. Right now the only way of producing Francium Metal is through a particle accelerator, and even then, it is such a small amount, that it is hardly even worth mentioning. Also, it is impossible for you to "find francium" because it is so reactive that it vanishes a short time after being created, so for you to say"I found 30 grams of francium metal" it is really just a sign of your current chemistry edu

  • That was very cool

  • Give me more Francium👊👊

  • it is really dangerous

  • Hay science community, I found 31 grams of francium, suck it!

  • No point in the title. Sitll a cool video

  • He said cesium. Learn to listen

  • francium is illegal to own

  • @ContextofSalad58 There's not even enough Francium on Earth at any time to be owned by a single person.

  • Damn, cesium! XD

  • You don't see Francium in these videos because it's very rare and very radioactive. Throwing a chunk of francium into a bowl of water would, if the alkali family trend holds, create a greater and more violent release of energy than cesium, except the droplets of burning francium flying around the room would be very radioactive. It's be a dirty nuke on a small scale. Not a great idea.

  • @mvolesky1

    You forgot that francium is illegal to own.

  • @Telamon8 True, but given that only a few grams of the most stable isotope exist on the entire Earth at any given time, enforcement isn't really a problem. ;)

  • I like how potassium burns with a lilac flame.

  • Lithium + H2O = Hydrogen Gas.

    Light it!

  • Apparently Francium can only exist on Earth in a solid form for about 27 seconds. lol

  • Dat was........AWESOME!!!!! :DDDD

  • The whistle in the background. XD

  • Beautiful. The best chemistry video on youtube! Well, these reactions here are all true, but never search for francium with water. Very few francium atoms exist due to its radioactivity, and as a result uploaders put nuclear weapons into their videos, and those are not francium reactions. Try imagining the cesium reaction but think of a bigger version of it.

  • You know what would be even better than putting Mento's in Diet Cola? Putting Cesium in a bottle of water!

  • You are never, ever going to see a video of someone putting Francium in water. It is simply too rare (half life of 22 mins, 30g in existance), and too valuable to do something silly like that with it.

  • The government (atleast in America) won't even let you by francium.

  • This video is stupid. I saw this exact same video for sodium's reaction in water. Francium is radioactive anyway,so they could of used it without protective gear. This video sucks and is a fail imatation of what wouldn't happen if francium were put in water!

  • Why not francium?

  • thanks for answering me....thanks!! for everybody.

  • Excuse me, the half life is 22 minutes, maximum. Sorry, I was mistaken.

  • Maybe because there's like 30 grams of it in existence and it has a half life of 8 and half hours? Seeing as you're likely too stupid to know what that means, it means every 8.5 hours, if you have 20 grams of Francium to start with, you'll only have ten. 8.5 more hours, 5. They'd have to have it shipped in within an hour to be able to use it, but I HAVE always wanted to see how big a boom it would make lol.

  • @43Jodo The 8-and-1/2-hour half-life actually applies to astatine, element no. 85 -- a non-metal halogen. Again, there's only about one ounce of it in the entire Earth's crust; and so not much is known about it. It may be a blackish, metallic-looking powder. But we do know that its properties are much like those of iodine. Astatine would not be quite as reactive; but this is more than offset by its sheer radioactivity (francium would be far worse, being an alkali metal in addition to that)!

  • My chemistry teacher showed me this exact video a couple weeks ago. o_O

  • Comment removed

  • Whats the point of the title?

  • @ilai456 because francium has the most violent reaction and its crazyest reaction and is highny radioactive the title is sarcastic

  • @ilai456 the point is that Francium is higher on the table and they are showing the previous metals as a scale plus Francium is radioactive which none of the others are highly radioactive, so you can imagine the heat generated to be FAR greater then any of the others and I am sure they would not want to deal with the after affects if they could do such a pointless experiment with such a precious material.

  • @ilai456 Francium was right after Cesium.... making a much bigger explosion...

  • @ilai456 Because after "Caesium" comes "Francium". :)

  • @ilai456 Also francium is raaaadddiiiooooooactive. oooooooooooooohhhh

  • @ilai456 Francium is a step above cesium in terms of reactivity with water. There would be a huge, violent explosion. Try searching it on youtube- you'll get footage of atomic bombs detonating.

  • @ilai456 Francium is the most alkali metal. It comes after Ce, however it is not very stable and I am not 100% sure but I believe it can't even be collected and dropped into water because it is just to unstable.

  • @ilai456 A very small amount of cesium causes a violent explosion and breaks glass. By the context of the video, you should be able to figure out that francium is even more powerful, without any knowledge about it. The title implies how powerful francium is.

    Or, are you asking why titles are used?

    I bet you feel retarded now.

  • @ilai456 francium is stronger than cesium, if francium were to be used (unlikely because its radioactive and i heard theres like next to non on the earth) it would probably destroy the desk with just a marble sized sample.

  • @pivotfann It only occurs naturally or otherwise for a fraction of a second.

  • @ilai456 cesium broke the glass. francium breaks the house.

  • @ilai456 Because Francium is the last one in the series of alkali metals, whihc would be alot bigger explosion

  • @ilai456 How about you bring some Francium into the shower with you, and then tell me the point of this title.

  • @ilai456 because francium is a extremely rare metal! extremely dangerous! it is illegal! that is why! since you saw caesium broke the lab glass container francium will be worse! that is why fancium is such a rare metal in fact so rare and dangerous they won't even show it on tape! know one has! if someone did show an actual video with francium it would be a world first! so remember im going to put this very short and bluntly very dangerous! highly explosive! stay away from it at all times!

  • At least not brainiac

  • Title noted in up pretty stupid ..

    Worldwide, there's only 30 grams of Francium and only scientists have access to them

    So no one can just walk down the street and suddenly see such an explosion

    anyway thank you for video :P

  • 1:00 for big explode

  • there's said that the reaction with sodium is a bit more bigger, I thought it was a bit bigger......

  • Why not Zoidberg ?

  • @Toorgorax *Francium

  • I think that Michael Bay would LOVE FRACTINIUM! And a question. I've been given a cheisty problem in high school. If exactly 1.5 grams of FRACTINIUM would be exposed to H2O, what would the aftermath of the blast be? Would it be

    A: an apartment room gone

    B: a story of a suburban house gone

    Or C: an entire house blown to SHIT!

  • the last one it s  cesium -.-

    Li(LIthium), Na(Sodium), K(Potassium), Rb(Rubidium), Ce(cesium), Fr(francium)

    this is the order of the alkaly mettals... and francium(in that ammount of cesium) should blow with that house atleast

  • Man even the smallest amount of francium would blow them all up!!

  • We did this in school and we shat bricks when the Cesium suddenly blew up.

  • francium is too reactive, it explode with water vapor in air

  • @wyattchung The reason why no one can use Francium is not because it's highly reactive, but that it's radioactive.

  • @ilovewafflez15 and because francium has a half life of 22 min so it doesn't stick around long

  • oh Cesium. *whistle*

    

  • ok thanx i got it lolz ppl chiill!

  • i love francium

  • lmao at cesium

  • cesium is boss

  • Awesome

    

  • It doesn't show francium because putting that amount in that glass of water is like planting C4

  • @ilovewafflez15 Also because it's illegal to have it.

  • it doesnt show francium

    change the name of the video or something

  • @kakashihatake169 it doesn't have to the point is that you see how it becomes more and more explosive as you go down the alkaline metals... francium is at the bottom so you get the picture

  • @kakashihatake169 It says why NOT to use Fr. and shows it

  • Win for science
