I just randomly found one of your videos today, you now have a like and a subscription and new fan. I wish to make a 'Jacobs Ladder' and I found your video when you made a 50k voltage device by using 24v supply and a flyback device, that was some very fine work indeed. I hope to make a small Jacobs Ladder in a sealed container as a novelty toy for a friend of mine. I would like to keep the size relatively small, like an Executive Toy that could sit on his office desk, any advice would be greatly appreciated. Peace and best wishes from Ireland mo chara.
In the pharmaceutical industry we'd call that an ampoule, before and after sealing. A vial is a glass container sealed with a stopper, usually made of some type of rubber.
@@AdvancedTinkeringdude your accent tells me that you’re german so the word „Ampulle“ should be the first thing that’s coming to your mind when you see that thing 😅
I have no clue what someone would want this amount of pure caesium for but good lord. The sheer guts you have to remove the flasks not once, but twice- without wearing gloves or anything, floors me. Please stay careful, man. This is basically elemental napalm
Gloves aren't of much use if you're handling materials that will not only end your day but also close the lab/the building/the area indefinitely if you drop them...
I'm not a scientist by any means but watching this I can't but be curious as to what kind of reaction you could get if you were to submerge one of the ampuls deep enough for glass tube to collapse under the water pressure. I imagine it wouldn't have to go too deep considering the glass is already a vacuum so adding more external pressure (again I'm not a scientist but from my understanding that would mean that the glass only receiving pressure from the outside) so I guess the questions that come to mind are how deep would it have to go to have a catastrophic failure, and what kind of reaction would happen/ be visible/ observable from the surface
@@d0h depends on they type but initially only the outermost layer of caesium would react. It would be a potentially survivable explosion but your hands are gone if you're not using idk, 5mm kevlar gloves or smth. Furthermore, that's pretty much a glass frag
yeah distillation of metal is pure insanity to me, since its a metal i instantly picture it as one of the hardest solids possible, then we have this "metal" thats just chillin in liquid form and decides to become cloud at high enough temp
The fact that metal can be distilled from a solution in the same way alcohol can is amazing to me. It’s metal in a liquid state so I guess it’s not THAT counterintuitive but I suppose I just never thought about this before. Really neat,thanx!

That lampwork is not trivial, well done! Based on the quality of your work I think you've probably seen this trick before, but I want to encourage you to try cracking off tubestock with the hot tip of a glass rod instead of the torch and water method. It'll take you a couple tries to dial in how much hot you want for the weight of tubing, but once you do I think you'll find it easier to avoid those spiderwebs you get the way you're doing it. No water, just touch a hot rod onto your score and hold it there til it cracks. When your heat is right for a clean break, that's a good 2-10 seconds, longer than you'd expect. Sometimes they even go 30 seconds later as they're naturally cooling down. The key advantage to this method is you get to control both the temperature of the glass rod, and how much mass of glass you heat up to deliver x heat at y rate.
I would call myself a multipurpose talent in different topics like mechanics, electronics and software. But chemistry is one of those topics i barely get the basics. Anything above that is magic for me.
I see the glassware meant to be melted together all the time, but I've neither ever used it or ever even seen it used untill your video. You are very skilled at it. The closest I've even done is making ampuals out of large test tubes by heatingnand stretching the top to a thin tube, filling it, then sealing it. I used them for Bromine, which there is no other way i know how to store safely and not get cancer or poisoned due to it leaking or exploding. I tried vials with rubber stappers crimped on with metal, but is failed greatly. Luckly i left it outside.
I've been following your journey for some time, and this is an incredible culmination to your skill and dedication. Congratulations! Amazing and joyful science.
I used to be a lampworker and my chemistry is lacking, but this was amazing to watch. Good job keeping yourself safe, that procedure is something i could never do out sheer fear. Chemistry is beautiful and thanks for showing the distillation footage never seen liquid metal be distilled. Do you ever worry about the stress the glass is under when you're heating it up during the distillation
A nice thing to have is an oxygen sniffer to ensure full purge . Very cheap to buy and quite surprising when you first get one when you see how the purge takes place in the different setups. Thanks for your videos man it's fun to watch ❤
What really rips a hole in my mind is that there was a first person ever that discovered the process of how to do this. I can not wrap my head around how that idea would even manifest itself, and then formulating a plan to create a previously unknown substance out of nothing. It's so fascinating
No idea how this video got into my recommended box, but i like it. Watching the cesium condensate on the glass walls just to vaporize instantly when you go over it with the flame, just doesn't seem right for a metal xD I love the final shot with the crystallized blobs in the vial. Melting point of 28,44°C, so it's mostly solid when sitting on the counter, but melts in your hand. That's so cool.
That little bit of reactivity you spoke of when you disconnected the stainless steel tube would have been something I would have liked to see. Feel free to add moments like that to the video. It is an important part of the learning and understanding process.
I've been looking for high-purity Cesium everywhere and I just can't find any! I LOVE how clean this looks! I'll pay you to make some for meeee! Seriously!
I can’t get enough of watching this video, cesium is one of my favorite alkali metals along with rubidium and potassium given that we can easily see it as a gorgeous shiny metallic liquid as it melts at a reasonably low temperature unlike say sodium which needs something like boiling water in order to melt.
The stuff is fairly easy to make considering how reactive it is. Refining cesium salt and containing it in a glass tube is 2 different things. Potassium Metal was scary. Even small pieces will light up when reacting with organic matter.
Incredible! Cesium is definitely my favorite element, I read that there is an alloy of sodium potassium and cesium which melts at -79 degrees. You song see many channels dedicated to such reactive elements!
I dont think even Applied Science (basically a genius, to me, also) could pull this off I'm not aware if he possesses the glass skill you have.. Absolutely fantastic work thank you for sharing!
Ben from Applied Science if without a doubt a genius. I am pretty sure that, if he would really try and learn/practice some glass blowing, he would be able to do it. But thank you a lot for the compliment!
i managed to make a shiny 5mm drop of shiny sodium in an ampule made from a pipette, just put it in and melted the sodium several times and made it consume all the oxygen, once it stopped tarnishing anymore i could melt it and roll it to the other side of the test tube and then shortened the tube, was quite happy with the results and then i see you do this haha
I melted some sodium hydroxide in a nickel crucible with a sprit flame and electrolysed it with a car battery, the sodium would gather around the electrode and could be collected. The current was 12A. Do not spill the molten sodium hydroxide. My friend spilt some on a notepad and it ate straight through the thick pad of paper instantly. I tried potassium hydroxide but it didn't work. I read that the potassium dissolves in the hydroxide, not sure if this is the case.
That is absolutely gorgeous!!!!!!! What a satisfying feeling to watch it!!! Never thought I would say that about cesium but there it is😂 I would stare at it a lot if I had some of that beautiful substance
It really is the most beautiful stuff. Like, can you imagine showing this to 17th-century alchemists? They'd think you'd discovered the elixir of life.
Before you said it was cesium, I thought it was just mercury. I had a much larger and more precariously contained stash of mercury when I was a kid. My dad would remodel apartments and hotels, and one of my jobs was to remove all the thermostats. I'd gather up all the mercury switches, and dump them in bucket. It was like a 1/4 of the way full before the sides started to bulge. My mom made me surrender it to the university because she was afraid I was going to spill it and poison the water supply.
I don't see any problem there. That's standard practice. Good luck sealing a borosilicate glass vial properly without an propane/oxygen torch ;) And what would the gloves be useful for? Gloves that would protect you from burning cesium would decrease your dexterity too much and thus increase the risk of accidents.
Holy shit! 👏👏👏👏👏 Dude, this was my first video of yours and it was awesome, I loved it, Fantastic work on the project and the video and how fucking cool is that insane pattern thing it’s doin inside the glass, that’s incredible!! Did You not geek out over that? Now I’m off to binge the rest of your work, I bet it’s all gonna be just as incredible! 🙏🏼 Really appreciate You Man!
I know very little about the world of chemistry and in particular the metals like this that are most amazing but I can say for certain fear of mercury is nothing after seeing this stuff!
This process looks dangerous. I imagine seeing this hundreds of years ago would look like magic. The level of skill makes you like a magician. Nice job.
Absolutely amazing work! Cs has a boiling point of 690 °C under normal pressure. Do you have an idea, at which temperature this stuff distilled over at your low pressure?
Are you thinking about purifying the potassium metal shown in one of your recent videos using this same exact distillation method? BTW cesium is one of the most gorgeous looking elements of the entire periodic table!! I would love to get my hands on some cesium metal especially on some at such high purity that it won't adhere to the glass at all when melted, sucks that a gorgeous golden colored metal that can be melted easily is incredibly pricey and dangerously reactive. 😞😞😞😞😞😞
Yes, I am currently working on distilling potassium to get a large clean vial. But I also want to make the potassium myself. Yes it definitely is beautiful :)
What I think is impressive is that the Cs doesn't stick AT ALL to the glass. I have a 5 gram ampule of 99.95 purity from a respectable chemical lab supplier (hasn't broken in 20years thank God!) and it sticks just a little especially at the tip where the glass was sealed. And it has a concave meniscus, which indicates some albeit redicilously little contamination... But yours flows almost like Hg. The inside glass must be VEEEERY clean. Amazing how just the slightest impurities can mask the true nature of materials. Our vast semiconductor industry and by extrapolation our digital age would be impossible if we were only able to achieve 99.99% purity... An operation room is a pig sty in comparison to a semiconductor factory. Good craftsmanship!!
That's some high level shit. Your channel is underrated. Damn from the technical view this is the same level as chemicalforce. You could improve a little with the video editing but damn this is so impressive from the technical view.
Thank you! Yes, there is a lot of improvement when it comes to editing and filming. But it's always hard to film when you are alone and busy working on something.
I thought about that. But no. As you can see, the amount of cesium that condensed even at the very beginning of the stainless steel hose is minute. In addition I bent the hose in a circle so cesium atoms making it into the hose would have to hit the walls and condense on their way to the pump.
Beautiful video! What do you recommend for storing a cesium ampule at home? I was thinking about a steel box with a larger amount of sand surrounding the ampule. Any better or additional ideas for safety?
Thank you! Yes, I think an airtight steel box with some PE foam with a cutout for the vial would be best. So even if the box gets knocked over, the vial will be likely to survive. With sand it would be more likely to break. Just make sure the foam does not react with the cesium, otherwise pressure could build in the box if the vial breaks and gaseous reaction products are formed.
Thanks for the reply. Do you have a recommendation of a commercial polymerfoam with these properties (maybe even a supplier)? My reasoning with sand was that the cesium reacts with sand and gets quenched rather than being oxidized in air and starting a fire.
The cesium would not react with the sand in my experience. Of the steel box is airtight, I don't think it would start a fire, there just not enough oxygen. There are a lot of suppliers of polyethylene foam on the internet. In my experience PE will not react with cesium.
Wow 🤩 this is truly amazing! I clearly have no clue what is going on, but this is one cool project! Science is so fascinating! Love this and glad I have found this channel!!
Is it possible to use an induction coil to hear the ceasium? That would allow potentially fine control over the heating rate, and avoid over heating the glass.
Has there ever, in the history of the universe, been that much pure cesium in one place? Has that crystal ever formed anywhere ever before? (Well maybe on Earth ...) what a rare and beautiful event!

There is something very disturbing yet beautiful about watching a metal be distilled. It seems like something that should not be possible.
I mean, its a liquid at room temp. Where did this metal come from? I agree with you, this is wild.
Chemistry is amazing.
@@MattShine11_pure_ caesium is liquid at or near room temperature. It's found in Pollucite ore and primarily mined in Canada.
yeah distillation of metal is pure insanity to me, since its a metal i instantly picture it as one of the hardest solids possible, then we have this "metal" thats just chillin in liquid form and decides to become cloud at high enough temp
We do it with water all the time, tho that's technically more like a mineral when it's solid
My heart was in my mouth when you were sealing the ampoule, respect sir that’s a great project 👍🏻

Really amazing to see metal vapor and condensation. I heard there are some exoplanets where it rains molten iron 🌧
What I think is impressive is that the Cs doesn't stick AT ALL to the glass. I have a 5 gram ampule of 99.95 purity from a respectable chemical lab supplier (hasn't broken in 20years thank God!) and it sticks just a little especially at the tip where the glass was sealed. And it has a concave meniscus, which indicates some albeit redicilously little contamination...
But yours flows almost like Hg. The inside glass must be VEEEERY clean.
Amazing how just the slightest impurities can mask the true nature of materials.
Our vast semiconductor industry and by extrapolation our digital age would be impossible if we were only able to achieve 99.99% purity...
An operation room is a pig sty in comparison to a semiconductor factory.
Good craftsmanship!!
God tier indeed!
Very good video and work, and your accent is the cherry on top
Thanks again for beautiful content !
Cesium in the ampule looks so beautiful, even more than your glasswork. Great job, man.
That's some high level shit. Your channel is underrated. Damn from the technical view this is the same level as chemicalforce. You could improve a little with the video editing but damn this is so impressive from the technical view.
Thank you! Yes, there is a lot of improvement when it comes to editing and filming. But it's always hard to film when you are alone and busy working on something.
You let us see more of the behind the scenes though. I think it’s a great learning opportunity with your explanation along the way
I love everything about this. Thank-you
Impressive, well done. Do you worry about any of the cesium making it over and messing up your rotary vane pump and/or oil?
I thought about that. But no. As you can see, the amount of cesium that condensed even at the very beginning of the stainless steel hose is minute. In addition I bent the hose in a circle so cesium atoms making it into the hose would have to hit the walls and condense on their way to the pump.
Cesium is one of my favorite metals. I NEED TO BUY CESIUM METAL!
Beautiful video!
What do you recommend for storing a cesium ampule at home?
I was thinking about a steel box with a larger amount of sand surrounding the ampule. Any better or additional ideas for safety?
Thank you! Yes, I think an airtight steel box with some PE foam with a cutout for the vial would be best. So even if the box gets knocked over, the vial will be likely to survive. With sand it would be more likely to break.
Just make sure the foam does not react with the cesium, otherwise pressure could build in the box if the vial breaks and gaseous reaction products are formed.
Thanks for the reply.
Do you have a recommendation of a commercial polymerfoam with these properties (maybe even a supplier)?
My reasoning with sand was that the cesium reacts with sand and gets quenched rather than being oxidized in air and starting a fire.
The cesium would not react with the sand in my experience. Of the steel box is airtight, I don't think it would start a fire, there just not enough oxygen.
There are a lot of suppliers of polyethylene foam on the internet. In my experience PE will not react with cesium.
Wow 🤩 this is truly amazing! I clearly have no clue what is going on, but this is one cool project! Science is so fascinating! Love this and glad I have found this channel!!
*This video is a good example of really smart people doing really dumb things. I'm glad I'm not his neighbor*
You sound fun
The result is simply stunning!
Is it possible to use an induction coil to hear the ceasium? That would allow potentially fine control over the heating rate, and avoid over heating the glass.
Why not just use your ears?
Beautiful! I too would be extremely apprehensive when heating the apparatus with the torch!
Excellent music choice.
So mesmerizing and beautiful. Thank you for sharing this!
Has there ever, in the history of the universe, been that much pure cesium in one place? Has that crystal ever formed anywhere ever before? (Well maybe on Earth ...) what a rare and beautiful event!
Definitely perfect soundtrack 👌 🥹
Very sinister, yet very beautiful
