@@yaykruser Yes, I have seen 2 people do it by starting with CsCl which is a cheap source of cesium. They used lithium as a reducer. They also used a distillation setup under vacuum to collect the cesium gas and condense back to liquid. It is probably the same for other alkali metals and earth metals. The salts are a cheaper source for the element.
Honestly one of the most impressive things about this is how steady you are able to keep your hand to drop a tiny droplet perfectly onto a tiny lump of caesium
THIS is the Perfect way to present an explosion! From beginning to end, constant slow-mo speed, constant camera angle, no fluff. This way you allow the viewer to take in the experience, not push a "cinematic" experience onto them. Thank you for the pleasure!
I appreciate the amount of effort you put into that intro, lol. Was awesome. Also, it's hard to overstate the production quality of your videos. They're undoubtedly getting much better (and they were never bad to begin with). You will certainly reach 1M subscribers rather quickly :-D
"Existence is pain." - Cesium An element so angry putting it in ammonia makes it tear off electrons hard enough you can see them with the naked eye. I dearly wish my Chemistry class had been more practical and demonstrative, I may have payed attention.
I've only ever had cesium combust in air by itself once and that was when I was bottling 10g and spilled it. But it spread out a LOT and I think that the high surface area was what caused it to catch fire. I just dumped a bunch of mineral oil on it and extinguished it quickly and was able to save around 4g.
R-I-g-h-t, and you just happened to have some mineral oil near by Mr. Fumblefist, hope you were removed from your position for being too clumsy with dangerous chemicals.
I don't think I'll ever stop being amazed with the ease with which this man handles absurdly dangerous chemicals safely. Including while combining them in the specific ways that make them exceptionally dangerous in the first place. My hat is off to you, good sir!
cesium is very reactive, but is not actually that dangerous on its own. you might be thinking of the radioactive isotope of it, 137. THAT is a great source of gamma radiation.
cesium is chemically safe. What makes it dangerous are radioactive isotopes like cesium 137. Cesium 133 is non-radioactive, so its like copper or aluminium
I'd love to see you do a Collab with Gav & Dan, or Destin. The quality of their slow-mo, paired with your chemistry knowledge, would be an amazing combination.
Some of these reactions start very slowly, showing little to no effect for several seconds after contact, and then explode in less than a millisecond. To me this is a great display of the explosive power of the exponential function. Even when the base is only slightly above 1, you only get a limited time before the function explodes. (Try plotting y=1.001^x in something like Desmos and then zoom out until you see anything happen.)
I think part of why it reacts so violently in water (more than potassium, for example) is because of its actual reactivity, but part of it is it’s dense enough to sink below the surface before bursting. That means that instead of blowing up into the air it blows into more water completing the reaction.
And another part of the explosiveness comes from cesium’s low melting point, turning into a liquid with minimal heating from room temperature. The said liquid then gets its electrons ripped off by H2O and causes a Coulomb explosion where bits of positively charged alkali metal particles violently repel one another. This is exactly the reason why NaK explodes like cesium does, sodium produces delayed explosions (if it does explode at all), and lithium simply does not explode when thrown into water.
Cesium bismuth amalgam has some pretty interesting properties. I would love to see a beautiful bismuth Crystal dissolved in some gold cesium. The aliens are sure to come after such alchemy.
This video was absolutely incredible, but I feel like I would've enjoyed more commentary on why certain things were the way they were. Like the pinkish purple smoke, or how slow the liquid combination was to come out of the tube. That being said, this video was absolutely fantastic, and I'm overjoyed that I got the opportunity to watch it
Hello ChemicalForce! Traditional soaps use NaOH and KOH as bases and LiOH is used to make lubricating grease. I wonder what happens if more exotic forms of base such as RbOH or CsOH were used instead. What kind of "soap" would they produce? Perhaps this could be an interesting idea for a future video.
I would like to see this too! I’d like to see what kinds of soaps RbOH and CsOH would make. And for that matter, FrOH and 119OH/UueOH if they ever manage to make element 119.
@@129140163 If only Francium was stable enough to do chemistry with. It would've probably looked like extremely reactive dark metal liquid (or almost) at room temp
By far the best quality video on caesium and its reactions I’ve ever seen. The violet of the caesium-tainted hydrogen flame with water is clearly visible, and the solvation in ammonia is a revelation. Slo-mo filming makes all the difference.
I swear I learn more about chemistry from youtube than I ever did in chemistry class. Absolutely incredible to see this stuff in the safest environment possible. At my house hiding behind a computer screen lol.
Sometimes I look back at history and say "a mere 200yrs, we've gone from 15-30min exposures on daggeurotypes, to 1000-100k FPS cameras" and that advancement is itself truly amazing; what we capture with it is a million times more.
Dude I'm so jealous, I wish I could lay my hands on some wonderful chemical compounds like you and make things blow... I'm a chemistry student and I'm so freaking excited to have my own lab someday :'D
@@MrJef06 Cesium is rare but very expensive to produce! Would've been cool if he recycled the cesium he destroyed!! But that's absolutely tedious and might not be even worth doin'! If I was him, I would store it and periodically show it to people just to prove I'm expert in chem coz I got access to a rare reagent! 😂😂😂
The shock waves we could see on a few reactions were awesome. Some particles got to surf the shock wave a few times. It looked amazing in slo-mo. The cinematography here just keeps on being amazing.
Cesium is so interesting compared to the rest of the alkaline metals. I wonder if you could show some of the soluble cesium compounds to show why the radioactive isotopes are so dangerous?
this is not the radioactive isotope of cesium (137). you can only get that as a byproduct of nuclear reactors, and no regular citizen can own it without special permits. cs137 is a heavy gamma emitter, which is what makes it so dangerous. you would not be storing it in glass ampules :)
If only my class in high school was this interesting we’d have so many more kids my age interested in chemistry and science. Im not bashing our teachers. It just seems like the ones I have are just there for the paycheck. No excitement, no passion. Just the Peanuts teacher basically. That purple smoke towards the end was BEAUTIFUL!
I actually had to catch my breath. Usually I watch in awe, but this time other people in the house could hear me yelling OMG. What a treat it is. Thank you my friend!
amazing! I miss my labs classes at the university. But this is way far from what we used to see in the first grades. Thanks for share it. Beautiful and quality imagens
And while it can and does get stupid expensive for crazy frame rate... That would be my *only* ask. Some of these reactions... Haha like the nitric here... No other way to see what is really happening with some of them. Not to mention on so many, that's where the beauty lies as well. That said no I'm not complaining. It's excellent even as it sits. Nobody else does anything like what he's got going on here.
Watching stuff violently explode to epic music is very satisfying. My best chemistry teacher in high school did show us similar videos (on VHS, before RU-vid was popular) and I loved it, but yours are way better, ChemicalForce. It's amazing how far content on this platform has come when it can easily surpass professionally made videos in quality.
Thats a LOT of damage! An excellent videa as always! Especially the chloroform reaction I’ve never heard of before. Might try it after I get around to make some cesium.
Amazing! Thank you for giving us the opportunity to watch dangerous substances from a safe distance. One would also like to see a "making-of-video" to learn how you managed to film this without damaging yourself or your equipment.
this channel is unhinged. it has some of the most expensive and dangerous chemical demonstrations available online and every single video has completely unnecessarily tense orchestral music
If by "unhinged" you mean awesome! "most expensive and dangerous chemical demonstrations available online"... "Unnecessarily tense"... Think about that for a second. I think you'll find saying those two things in conjunction doesn't really make sense. I bet the tense music helps to call the casual (non-chemically-inclined) viewer's attention to how expensive and dangerous the chemical demonstrations are, at least subconsciously.
I loved this video. I can not imagine a more FASCINATING episode, and the introduction was very professional! Really, your videos always look like a million dollars. What a surprise it was to see beautiful golden cesium turn black and ugly so quickly.
Such spectacular and beautiful reactions. I particularly liked the Fluorosulfonic acid and Bromine reactions where you didn't drop it right on top and allowed just the tiniest bit to contact to show the reaction a bit slower and emphasize just how little of the stuff you need for a violent reaction.
Periodic videos is only thing I've seen with Cesium that one ups these reactions. Years ago they had a video series of fluorine gas. A chemist who specializes in fluorine use a quartz glass canister and reacted Cesium in slight vacuum and introduced elemental fluorine at about 1/4 atmosphere pressure. Produced a blinding bright white light during the reaction. Nothing violent.
@@ChemicalForce yeah man I've really enjoyed these videos. The depth an breadth of your knowledge is astonishing. Are you a professor somewhere or what is your academic background? Thanks for making these videos. The production quality is amazing.
I'd really love to see someone like the Slo Mo Guys do a video with you one of these days where some of the super fast explosive reactions are filmed at an extremely high frame rate with one of their special camera to truly witness the incredible reality of how quickly some of these chemicals/elements can go off. Just imagine the cesium and fuming nitric filmed at 100,000fps instead of only 1,000. Anyway, I very much enjoy your channel. Here's to 100 more! Hopefully the world doesn't end before then!
