@@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 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 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
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.
"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.
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'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 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.
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
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.
This video shows what is so fantastic about youtube. We get to see you actually doing what we have dreamed of doing all our lives! Incredible quality too.
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.
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.
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
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.
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.
The only two metals that are gold in color are the most reactive(cesium), and the least reactive (gold). Gold doesn’t ever corrode outside of laboratory conditions
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.
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

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 :)
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 UA-cam was popular) and I loved it, but yours are way better, ChemicalForce.

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.

If I trusted myself enough, I'd certanly buy an ampoule.

Fist you pay, then you play.
Putting any alkali metal in ammonia produces solvated electrons though. Even the group 2 metals do that, and even some others.
Any alkali metal does that, stop it with the cheesy comments
@@BackYardScience2000 I would argue that all the group 1 and 2 elements share the philosophy of Cesium that existence is, in fact, pain.
