my chemistry teacher has been banned from using certain amounts of potassium, as he used to use large pieces that then exploded and caused the fire alarms to go off & the entire school was evacuated.
My teacher talked about how back when they used to use sodium and lithium, there was a time when they used too much and had to take it out, they put the remaining pieces back in and let them burn out. They didn’t realize they got some on their hands, and when they went to wash their hands, there were flames coming off their fingertips. There was also a time when one of their students put in too much and the subsequent reaction burned a ceiling tile above them.
Ever notice that the explosions on Brainiac are (at least dynamically) very similar, even though they claim to use a wide range of wildly varying explosives? This is because they use a few easily available, stable explosives to simulate the effects of dangerous, complicated or difficult to obtain explosives. This is quite a good example, because although the reactions show would be very violent they would be utterly unlike what is shown here, especially carried out in an open bath.
This clip is fraud. It's totally fake, presented as fact. In fact Rubidium and Caesium do not make larger explosions than Sodium because there is more than just the reactivity at play. This was not widely known at the time of filming, and was effectively discovered by the Brainiac team. They could have written a paper about it. But instead they use conventional special effects explosives to fake the result they wanted.
a tiny vial of that size wouldn't even be all that violent at all. But big explosion get you ratings so they gotta Michael Bay it up by faking it with pyrotechnics.

If you knew anything about chemistry you would know that you can calculate the energy that is released during the reaction. And if you would do the math you would realize that it is by far not enough energy to go off like that. On top of that they also admitted that they used explosives because the reaction was not spectacular enough. you can even see the cable.
Will always be one of my favourite brainiac episodes😊❤️ my science teacher showed it to everyone in the class when we studied alkali metals and I kept myself from screaming OHMYGODBRAINIAC😹😹
The interesting thing about these alkali metals is that their reactivity isn't exactly proportional to the reactivity. for example sodium isnt as reactive as cesium, but as it reacts it builds up a cloud of H2, so when it ignites it blows up and the bang is very big, whereas cesium ignites its hydrogen immediately, making a slightly smaller explosion. Science!
The hydrogen gas explosion contributes more to the overall visible size of the explosion than does the initial metal-water reaction. When you go down the periodic table from lithium to cesium, the atomic weight goes up from 6.94 to 132.9. Higher atomic weight means fewer atoms per unit of weight, and the amount of hydrogen gas generated decreases. So 5 grams of cesium liberates only about 1/20 as much hydrogen as 5 grams of lithium and a bit over 1/6 as much as 5 grams of sodium.
can't believe this is actualy aired on tele. Any highschool student who had a basic understanding of how the periodic table works could tell you that a gram of Rubidium would not produce enough gas, no matter how fast, to break a half a meter diameter hole in a bathtub.
+Jason Zhao lol what makes you say that? have you learned ionization energy (the energy required to pluck off an electron)? wait until you take physics and you see what a gram of radioactive elements can be made to do through nuclear fission (aka nuclear weapons). maybe the video is fake, but the science behind it isn't.
***** Is this nuclear fission, no. And also, nuclear reactions is not covered in physics, suggesting that you havent even been to High School. Also, yes I know what ionization energy is, they litteraly teach you that in 8th grade.
+nygeek64 sure, and you must know so much about science right? You must be a god to be able to recall something straight out of second semester 8th grade science. Really? You are going to tell me that I don't know anything when you just compared a simple alkali metal oxidation to nuclear fission?
+nygeek64 Basic stoichiometry tells us that 1 gram of Rubidum would produce .13 liters or 130ml of H2 gas. That is definitely not enough to blow a hole in a bathtub
Alkali metals are HIGHLY reactive as they only have 1 electron on the outer orbit, making them very very unstable. They react with the air too, which is why they are stored in thick oils, and the argon things.
the francium isotope with the longest half life is at 22 minutes or so. even if we could produce enough in that time, it's so radioactive it would violently destroy itself.
There are a few different ampoules that can dissolve in water, but they are not glass. On the other end, that is not the only thing that makes this video fake. In certain frames (this has been proven) there is detonation cord, meaning explosions were used. they used more explosives, for more reactive alkali's. Overall I agree! (I think the ampoules were made of some kind of soluble material
Well the rubidium ampoule that he was holding was exposed except for the end that was hidden by his glove. So we know that all of it is glass, but maybe the end under his glove was some kind of soluble cellulose or something. (Personally, I think the ampoule didn't even have any rubidium in it and the explosion just came from the detonator wires, as others have pointed out).
What is sadder is that Brainiac's show is undergoing "The History Channel Effect" -- The process where intelligent media programs ditch their factual, credible content and replace it with mindless bullish*t, in order to appeal to the majority of the American population (You can tell I watch CGP grey :p

The university of Nottingham did this with over a gram of Cesium. They even melted it and resolidified it on a plate to maximize surface area. it's nothing near the size of that tiny amount versus huge explosion. Although yes, this will help kids understand the dangers of alkali metals. My teacher threw a chunk of potassium into a beaker of water once to get our attention though, it was amazing
I love this show, we get it here in the States on G4. These guys do the science experiments everyone WANTS to do but can't. The 'Walking on Tapioca' they did was awesome!
In order to make something explode, you must change a solid/liquid to a gas, or cause a gas to expand in volume suddenly. It's like with gunpowder, pile the ingredients together without mixing them, you don't get a very good explosive. I find Brainiac funny and enjoy every series, but I wish they wouldn't fake things so much. It's annoying when they do that.
I was the person who texted John Tickle 4 years ago I was learning Triple Science and really wanted to know when alkali metals react with water. Thank you brainac science abuse for risking your lives for science. Thank you Richard Hammond Like your new secret service. By the way what happened in that bank robbery abroad with that cliff drop. Were you scared!
Mythbusters redid the experiment with exactly the same amount of Rb and Cs (2g), no explosions of that scale. Even with 2.5kg of Sodium and Potassium (though not reactive, the mass is significant), not a bathtub wrecker.

I like how people think these reactions are real. They would have to be in much more safe conditions because of how reactive these elements are so running away from the reaction into a van would not protect you
***** The whole point of this show is to teach kids science, so if they go showing these kids bullshit science then what have the accomplished besides making everyone fact check every one of their episodes.
***** Yes but most education tv shows don't have an education disclaimer. This is not some soap opera where they use junk science to make it more interesting, they mention how this is science and use specific amounts. And since they made it out to be scientific they are completely misleading people.
Sorry, but I can't resist; To the person who said everything you see on t.v. has to be true by law... how's that logic working out for you? Mythbusters Season 6, Ep. 13 examined the above video and utterly destroyed it. Now, since 2 television shows demonstrated opposite results, one must be fake. Personally, I'd go with the one that wasn't trying really hard to be a Mythbusters clone ;-)
omg, how the fuck did this get aired, any person with the most rudementry understanding of the periodic table knows that this is not how these metals react.
Cesium is in fact the most reactive metal in the periodic table including francium. It has an ionization energy of ~375 kJ/mol while francium has >380 kJ/mol . Also, francium is pronounced with /s/ not /k/.
It's funny the way people say it's fake when they really didn't studied chemistry like it has to be in order to eliminate it. It's perfectly awesome demonstration and it's real. Thanks Brainiac!
+TheWhydoesthis Here is 5 grams of Caesium underwater, which is more than twice the amount allegedly used in this video. Just search for: _''Underwater Caesium - Periodic Table of Videos''_ (it's on the Periodic Videos RUclips channel). Nuff said.
To everyone who's complaining that they missed Francium: it's insanely rare, and it's radioactive. Using francium on water would likely cause a bit of nuclear fallout.
we were told to watch this for Homework! This is an amazing, detailed video yet fun and interesting enough for people of ANY ages to understand! I find it fascinating learning about all of the different elements! Science is the core of our life, and the more we discover, the better it gets!!! oh and shout out for epic Mr A Harrison

2:37 whats with the wire, explosives?
ryandyc Yeah, 110% correct
Yep. It's fake. It's been debunked by actual scientists.
ITS REAL MY SCIENCE TEACHER TRIED IT AND WE HAD TO EVACUATE THE BUILDING IT WAS FULL OF SMOKE
@@bethanyyvonnexx bullshit
Mr. Tickle has become iconic in my science class 🤣💕✨
yea lol
Watched this is chemistry and laughed so hard. His running should be a meme
This is so incredibly fake. It doesn't deserve any of these views or upvotes.
***** The whole point of this show is to teach kids science, so if they go showing these kids bullshit science then what have the accomplished besides making everyone fact check every one of their episodes.
***** Yes but most education tv shows don't have an education disclaimer. This is not some soap opera where they use junk science to make it more interesting, they mention how this is science and use specific amounts. And since they made it out to be scientific they are completely misleading people.
"At no point did it say that the clip was for educational purposes"
**facepalm** Talk about missing the issue completely.
travelsonic The anti-vaxxers don't say that their claims are for education purposes, doesn't make it any less misleading.
Exactly - even if they don't say it, they still try to present information as factual when it isn't.
who needs bombs when you have this? xD
rita takla the explosions for some of them are fake namely rubidium and caesium
1:52 you see a cord leading in to the bathtub. Why is that there? Hmmmmmmmmm
This is the first time I'm watching this outside of school.
I miss this show SOOOO MUCH!!! 😭😭😭
Bruh my College is having us watch this and they are treating it like a ligament experiment.
at exactly 1 minute 53 seconds, u see a wire sticking out of the bath tub
WHAT A FAKE
Sorry, but I can't resist; To the person who said everything you see on t.v. has to be true by law... how's that logic working out for you?
Mythbusters Season 6, Ep. 13 examined the above video and utterly destroyed it. Now, since 2 television shows demonstrated opposite results, one must be fake.
Personally, I'd go with the one that wasn't trying really hard to be a Mythbusters clone ;-)
I feel like... This shouldn't have been in the science class playlist
We were meant to take notes of the reactions and I wanted to tell my teacher it was fake
@@Justrxby2763 oh shoot wait it's fake haha?
@@emilytrost4123 Yeah I looked in the comments as soon as I got this for a lesson
this is awesome!!! Good job!
I like Kenny Logins
omg, how the fuck did this get aired, any person with the most rudementry understanding of the periodic table knows that this is not how these metals react.
What are you, stupid?
+Drew Mortenson these elements dont react the way the show shows you
Matter879 yes, they can just not on this scale
Umm, no they dont, and you can clearly see a wire going into the tubs at multiple shots, just open you eyes man.
Matter879 I didn't say this was real so chill out. Just because it is faked does not mean that they react differently.
Today's lesson : explosives are fun.
There not explosives but some were used as it's fake
I got this for a science lesson the teacher thought it was real. They even said to write down notes of what you see in the video.
Cesium is in fact the most reactive metal in the periodic table including francium. It has an ionization energy of ~375 kJ/mol while francium has >380 kJ/mol . Also, francium is pronounced with /s/ not /k/.
It's funny the way people say it's fake when they really didn't studied chemistry like it has to be in order to eliminate it.
It's perfectly awesome demonstration and it's real.
Thanks Brainiac!
Yup... I'm no chemist but I do watch science videos that debunk bullshit.
+TheWhydoesthis Here is 5 grams of Caesium underwater, which is more than twice the amount allegedly used in this video. Just search for: _''Underwater Caesium - Periodic Table of Videos''_ (it's on the Periodic Videos RUclips channel).
Nuff said.
To everyone who's complaining that they missed Francium: it's insanely rare, and it's radioactive. Using francium on water would likely cause a bit of nuclear fallout.
considering the most seen in one place was only 300 thousand atoms, fallout wouldnt even be a concern
Busted! :D
I’m Korean student in Korea
My science teacher showed this
But in the comments, someone says this is FAKE!! I’m confused. What is the true????😭😭😭😭
재 재 it is very fake
@@joesanders5112 yep
we were told to watch this for Homework! This is an amazing, detailed video yet fun and interesting enough for people of ANY ages to understand! I find it fascinating learning about all of the different elements! Science is the core of our life, and the more we discover, the better it gets!!!
oh and shout out for epic Mr A Harrison
This is the best Video, which I See in my life! 😍😍
HAMMOND!!! :D
Too bad there are only 20g of francium on earth at any given moment. Too bad it also goes away in minutes
It doesn't "go away" in minutes...
Drew Mortenson I know it goes away pretty quickly becuase its half-life is really short.
ThePirhana12 yeah
+Drew Mortenson It has a life of like 30 minutes
