I don't know enough social media-ing to know if you'll ever see this (or to find any other way to contact you), but what size (OD x Height) does the outer can need to be in order to fit inside the furnace? I'm a TIG welder in a stainless steel pipe shop, I may be able to dig up some scraps and knock together a stainless version for you, I don't know how well a 300-series (all I regularly have access to at work) will handle that kind of heat though.

Samuel Ellenhorn - 2020-12-26

Cody, look here^

Thomas Nakagema - 2021-02-15

sent him a message on twitter just wait and see if he gets it

Brain Drain - 2021-07-21

Bro if you're serious about contacting Cody if you do some proper digging you'll find his address

CargoCultScientist - 2021-07-26

He has a Patreon

Joel Rampersad - 2020-11-16

Distilling Caesium. Yup, hes back to his good old self.

ak101farhan - 2020-11-26

No gf no problem !

I Drink Milk - 2020-12-13

@vitor de miranda henrique na the larger project videos like chb hes been doing are far better entertainment value. these are like easter egg side videos.

matti98 - 2021-01-09

@ak101farhan did his girlfriend leave him?

Christopher Leubner - 2021-10-22

Freshly distilled cesium, i'll take my shots neat, but i've heard that its a blast on the rocks... 🤓😁

Essi Schatz - 2020-11-15

Cody hits you with a 20 minutes long awesome video and ends it by saying: "thats pretty much all i got for now". What a guy.

xXPORTALXx - 2020-11-16

@RapMusicSucks1000 holy shit me too!

The XP - 2020-11-16

@RapMusicSucks1000 I take it rap music is not your thing

Noxulous - 2020-11-16

@RapMusicSucks1000 omfg ikr... i thought it was like... 7 minutes, i was riveted

masterimbecile - 2020-11-17

That ... that's about it.

Atomy - 2020-11-17

He says that every time tho

Scott Greg - 2020-11-15

This is Cody at his best. The top home science / chemistry youtuber imho. No sponsors, no gimmicks. Good enough quality production without fancy editing.

ZoonCrypticon - 2020-11-16

Exactly. And not taking it too serious with security measures, still producing excellent outcomes. For me he is the real "MacGyver".

Shadow God - 2020-11-17

Big thanks to the people on patreon who support Cody and his channel. I think they are the main reason Cody doesn't need to take on sponsors, the community is the sponsor.

Vincent - 2020-11-18

I wouldnt mind any sponsors, as long as hes making good money off them

Joshua Adkins - 2020-11-18

Sponsors shouldn't be a issue for any channel you like. You don't HAVE to watch the ad. It helps them pay the Bill's. Luckly cody has patreon so he doesnt need to take any. So be sure to go support him with a few bucks.

Seth Byman - 2020-12-06

Right!!! I love it!

ElementalMaker - 2020-11-20

Awesome work Cody! Can't wait to see what's planned for the Cesium 😁

Tom H - 2020-11-20

Congrats on 100,000 subscribers! Also I found some papers about making perchlorates by electrolysis if you'd like me to send you links.

Buck Starchaser - 2020-12-02

From what I've gathered, the purpose for this is mostly exploding toilets, mostly.

Lajos Winkler - 2020-12-26

It's cesium, not Cesium. It's a name of material, not a dude.

Buck Starchaser - 2020-12-26

@Lajos Winkler The IUPAC recommendation on the capitalization of names of the elements has recently been changed to recommend that they be capitalized the same as common nouns. They also changed the spelling of your example element. Caesium is its currently proper spelling, according to that same wiki article. Your arbitrary schoolmarming is undermined by grammatical inconsistency in your very statement, followed by a complete lack of research on the subject.
The humor side of your tragic literacy fumble is that you jumped into a pondering of what to do with some uncommon chemical in pure comedy form. shrug At least it was good for a chuckle.

Colton - 2020-11-15

You look much happier and positive in this video than in other recent ones. I hope your mental health is on the upswing ❤️

Cool Dr Money - 2021-02-06

These types of comments are so annoying

Cool Dr Money - 2021-02-06

@Colton u didn't congratulate any1 on being happy. U projected your perceptions of what U think happy is on some1 else. What if the person u are projecting onto was actually happy when u thought they weren't. Then u go and do ur psycho analysis potentially kicking off a cycle of introversion or harmful introspection. If u really were concerned, then you would be tactful and thoughtful regarding such things

Colton - 2021-02-06

@Cool Dr Money it doesn't take Sigmund Freud to tell when someone is unhappy. Picking up social cues is quite literally millions of years old. I was simply commenting that I thought he was looking happier, and that I hoped he was feeling that way. Your criticism is baseless.

TGJP - 2021-02-24

@Cool Dr Money what is your problem? do you not have a life?

Incroyables Expériences - 2021-01-14

Can you try do make a sort of DIY li-ion cell? It would be very interesting to try at home!

Azula - 2021-02-01

And burn it too.

An Anthropomorphic Talking Gourd - 2021-11-02

A homemade li-oin battery, aka a homemade fire starter?

Jo Veteran - 2020-11-15

Classic Cody, wears an astronaught uniform to go shopping, doesn't wear a mask when dealing with noxious vapors.

John Hennessy - 2020-11-24

@John La Duke Karen...

Jo Veteran - 2020-11-24

@John Hennessy boring

Jo Veteran - 2020-11-24

@John Hennessy more boring

Jo Veteran - 2020-11-24

@John Hennessy wow! amazing!

John La Duke - 2020-11-27

@John Hennessy @Jo Veteran Glad we all got tagged to come and watch your circle jerk. If you're casting around judgements, bear in mind that you've not only taken the time to read all of these comments, but also respond. Individually. But I doubt you were working on curing cancer or anything anyway.

TheIdeanator - 2020-11-15

Protip: molten alkali metals are one of the few things that can chemically attack teflon.

Robert LaPointe - 2020-11-16

Yes, Teflon stir-bars and sodium-potassium alloy can be hypergolic.

Drakkar Calethiel - 2020-11-16

@Robert LaPointe NaK and Teflon is hypergolic? Geez, I knew NaK is nasty stuff, but not that much!

Robert LaPointe - 2020-11-16

@Drakkar Calethiel I think it is due to the fluid NaK having a clean surface for reactivity. It reacts more like molten sodium. Plus, the lattice energy of NaF (~ 900 kJ/mol) is no joke - plenty of driving force there.

octet33 - 2020-11-16

@Robert LaPointe Never expected to hear "teflon" and "hypergolic" in the same sentence...

Alkali metals are evil!

Mark Short - 2020-11-17

@Robert LaPointe i didn't know that, thanks for the heads up mate

Wario Number One - 2020-11-15

Still waiting for you to make a Cobalt-Dysprosium alloy - a CoDy slab

deafkite - 2020-11-17

He should make a play button made of CoDy for 2M subs

【Chucklebutt】 ʘ‿ʘ - 2020-11-17

I wonder how much Dysprosium costs right now, it used to be pretty expensive.

bormisha - 2021-04-11

Yeah, Cody is lucky that his name in chemical elements is affordable. If his name was Osir, producing the play button could get more expensive!

Sasha - 2020-11-15

I appreciate you so much Cody, I know things have been really hard for you over the years but you're still here inspiring me with every video. And you haven't changed in all the ways that matter. You're a true scientist and I look up to that a lot.

Jason williams - 2020-11-15

The young fella seems to be back in action.
A typical old Cody vid so HIGHLY RECOMMENDED.

Beardwhip - 2020-11-16

Implying he wasn't in action previously?

Tyranzor Katastrophe - 2020-11-16

@Beardwhip you could tell from his content that he was a little burnt out and not his normal self, especially after his break up with Kanyon.

Jason williams - 2020-11-16

@Beardwhip Yes actually Beardwhip. It is just my keyboard warrior opinion so not worth a lot , but Cody seems to have been different for the last many months to a year. The vids have had a different spin and he has not had the jump in his step that used to be the case. I wasn't trying to be nasty .

foogoid - 2020-11-16

My nose looks like that after wearing a filter mask for a while...

Rollie - 2020-11-20

@Squiggummer Figgammus If you mean at the start of the video, it's from the safety glasses he's wearing, look at the imprint on his nose.

Willium_Bob_Cole - 2020-11-16

I don't know if you've been getting more sleep recently or what, but I feel like you look healthy, somehow refreshed, glowing almost, and that is great to see. Wishing you the best always!

Dancing Rain - 2020-11-15

Cody: successfully distills cesium.
Me: makes a small hydrogen explosion trying to distill the much gentler sodium.
I think I'll stick to electrolysis to get the lighter alkali metals for now :P

xXPORTALXx - 2020-11-16

@Dancing Rain unless one is funded by a large shady group of wealthy megalomaniacal bureaucrats, like say a government 😂👌

hussain abdullah - 2020-11-16

jSkrat Nyarlathotep - 2020-11-16

did you used liquid mercury? or some magical membrane?

jSkrat Nyarlathotep - 2020-11-16

@Jordan Sorenson nothing special, just, you know, some neutron source)

MrPossumeyes - 2020-11-18

I'm just happy being able to light my farts...

Nicholas Babusis - 2020-11-15

What happened to the other 65% of the cesium? Did it escape as vapor?

Wortnik - 2020-11-16

@ToasterBrain Don't forget exspecially! Never been to the US but hear it plenty on youtube! Pretty much a case of language evolving over time but still annoying af to some!

J D - 2020-11-16

@Hunter Bear Yeah, it's been a long time though. Didn't happen over night.

palndan - 2020-11-16

Stalagmites are cool, can you grow some different kinds. I have seen a coke bottle trapped in one (limestone) when I was a kid. Could be a cool time-lapse.

Laurie Rose - 2020-11-16

@ToasterBrain They can't spell caesium right either!

Benjamin Bradshaw - 2020-11-16

@Cody'sLab I myself wonder if the cesium is contaminated with lithium

NurdRage - 2020-11-15

awesome work!

Mark Short - 2020-11-29

@Piccuntso what was it that you deemed to be misinformation?

Piccuntso - 2020-11-30

@Mark Short DYOR

Mark Short - 2020-11-30

@Piccuntso if you can't answer then you obviously have nothing

Mark Short - 2020-11-30

@Piccuntso "DYOR" you sound like a flat earther 🤣

Jesse Parker - 2020-12-03

Glad you two know each other

Everything Explained - 2020-11-16

To improve the yield, consider grinding up and stirring the Li in, instead of just throwing it in as chunks. Even if it becomes a liquid eventually, it's not going to mix good enough, the molten mixture is too thick for a good mix.

John La Duke - 2020-11-15

I can't help feeling like there's probably a gadget at a kitchen supply store made out of stainless that has exactly the shape you need. Probably intended for something else entirely but just begging to be repurposed.

xXPORTALXx - 2020-11-16

I wonder how well it would hold up under the conditions tho, considering a kitchen implement like that would likely be thin af

SID - 2020-11-16

Don’t you mean Gadjik?

Jamie - 2020-11-16

Cooking pots maybe. The size could be an issue tho

PKMartin - 2020-11-16

A vacuum travel mug might do it: it's already a cylindrical double-walled stainless container. I'm drinking coffee out of one right now. The trick would be finding one with a big enough gap between the walls, and something else that would fit in between the walls. Custom is probably the way to go for this - I wonder if any of the welding/machining-related channels like This Old Tony would make it as a collab?

Giovanni Pelissero - 2020-11-15

Beautiful and ingenious method!
I'd compare this procedure to the metallic Sodium method without eletrolisys explained by Nurdrage.
This video is marvelous, thank you Cody for the great content, keep doing this stuff!

Giovanni Pelissero - 2020-11-16

For those who were wondering if other stuff gets collected, boiling point of:
Lithium 1330°C
Cesium Chloride 1297°C
Tin 2600°C

And Caesium 670°C

The molten tin spacer was a good idea.

ZoonCrypticon - 2020-11-16

And he used 1400 °F= 760°C for the furnace. So the Caesium would evaporate and escape easily at its boiling point of 690 °C leaving a gap for cross-contamination of at least 570 centigrades.

Giovanni Pelissero - 2020-11-17

@ZoonCrypticon that's the point, easy method for really pure cesium.
You can use lithium from batteries, but the CsCl is more expensive.

arjunyg - 2020-11-17

@Giovanni Pelissero Rudimentary or not, it appears to be a well-sealed container with nearly no opportunity for oxygen ingress. It should have worked better than it did, if the math was correct.

Giovanni Pelissero - 2020-11-17

@arjunyg he said that lithium didn't fully react nor the cesium chloride that has a melting point of 645°C. The temperature of the furnace wasn't so higher and had a container to pass before reaching the reaction vessel.
In my opinion a vacuum would have helped, plus some stuff must have escaped somewhere, the reaction isn't even balanced towards the cesium (definetly more reactive than lithium) even if you remove it from the products.

Gaius Caligula - 2022-01-24

I don't think anyone wondered about that, pal

Martin szmidt - 2020-11-15

when the slowmo kicked in i was expecting an explosion followed by a "shoot..."

ahaziah joshua - 2020-11-16

That'd be quite on brand

Liam Fox - 2020-11-17

Same lol, Slowmo on Cody's channel does tend to be followed by rapid unscheduled disassembly events.

Cesotoseot - 2020-11-19

[shrapnel explosion and metal fire]
"Well gosh darnit."

Ginger Inventor - 2020-11-16

Cody, you should be able to weld stainless with your set up by just using stainless TIG rods.

Cody'sLab - 2020-11-16

I can for sure stick the metal together but I haven’t been able to get a good seal. Maybe what I’m lacking is the skill.

Levi Cooper - 2020-11-16

@Cody'sLab you got this!

Ginger Inventor - 2020-11-16

@Cody'sLab Practice makes perfect!🙂

Finn Austin - 2020-11-16

I would wager that the instruction manual does indeed say that the furnace needs to be upright

goodiezgrigis - 2020-11-17

Real man never reads a manual, they are used to start a fire in a furnace.

Christian O'Connor - 2020-11-15

Love these. Keep doing what you do! Hope you're feeling better lately!

flymolo50 - 2020-11-15

This feels like a cody's lab from 5 years ago. I love it.

advint - 2020-11-15

I started watching you because of your mining and metal series I'm so glad to see you back at it after a few years

CAO Designworks - 2020-11-16

Eyyy! This is that classic Cody action! I can't wait to see what you do with the Cesium. It's always interesting watching you transform one material into another and what methods you use to do it.

Watcher - 2020-11-16

Silly me. Based on his introduction, I was expecting this apparatus to be less janky than previous ones.

G.I. In The Wasatch - 2020-11-15

And hopefully this design doesn't, according to your neighbors who called the cops back then, look like a pipe bomb..




Good news it doesn't! Bad news is that it looks like an anti-personnel mine now..

Unknown - 2020-11-16

@Gaming Ambience Live Because it's a fun explosive metal

Banjo Bear - 2020-11-17

Why say crap like this. There are plenty of YouTubers actually making weapons and stuff. Cody doesn't need this kind of discourse started again. It's so obviously a budget chemistry and engineering video.

john smith - 2020-11-17

time to get a type 10 FFL!

GPlumbob - 2020-11-17

@Gaming Ambience Live He doesn’t need a license for metals. The thing he got in trouble for was a radioactive isotope of hydrogen, which he did need a license for.

M - 2020-11-16

Is that type of retort named yet? The Reeder Retort has a nice ring to it.

BackYard Science 2000 - 2020-11-15

As soon as I master distilling cesium with plumbing materials he comes out with a new and better way. I used the cody way of using random materials for the retort, with the thunderfoot way of using a BBQ grill, only I upgraded to a gas powered blast furnace. It worked great! I recovered several dozen grams of cesium and had a lot of fun with it.

Gary P - 2020-11-16

Show us!

wild bill - 2020-11-16

Love Cody’s chemistry vids
One of a few that do things in a way most people can figure them out
No fancy devices or chemicals we can never obtain
Cody is one of the best

electronicsNmore - 2020-11-16

Great video as usual!

mundanestuff - 2020-11-15

Nice work. Good science meets good engineering to produce a valuable result.

Noel Jönsson - 2020-11-15

@BlueFire Animations it was uploaded on the 15th of November (today). this guy commented 4 hours ago.

BlueFire Animations - 2020-11-15

@Noel Jönsson fine. The time it was uploaded.. not the date

Noel Jönsson - 2020-11-15

@BlueFire Animations I can’t see the time it was uploaded just the date.

BlueFire Animations - 2020-11-15

@Noel Jönsson huh, odd

mundanestuff - 2020-11-15

Beats me. It was posted to patreon today, I watched it and commented. This is the kind of science and engineering that is sorely needed in this world, so I put my money where my mouth is and support it by a meager donation once a month. Must be we got a notification before the general youtube subscribers got it.

John McCann - 2020-11-15

Fun to see some sciencey stuff again. Seems like it’s been a while...

Clar Fon - 2020-11-16

"No one said the furnace had to be upright!"

Actually, Cody, I think a lot of people have said that. Doesn't mean they're right, just, they did say it. :p

Chuck Todd - 2020-11-16

The Major problem with inverting the furnace, is that it was designed to use convection cooling for the control element. With the furnace inverted, the controller is now in the hottest position instead of the coolest. I expect the electronics to die a horrible death. Also, the AC cord should melt through and become an electrocution hazard.

Noxulous - 2020-11-16

@Chuck Todd thats horrifying, i assumed there was gonna be a problem with him inverting it, just didn't know the nuts and bolts of exactly what till just now

goodiezgrigis - 2020-11-17

You can allways detach the controller and move it a foot away in the safe zone for prolonged use if that is your concern.

Nagy Péter-Szakállat Korporésön - 2020-11-17

@Chuck Todd The furnace should be grounded,if the cable melts and live wire touches the mteal body of the furnace,fuse will blow.

nbfdmd - 2020-11-16

I don't know if Cody mentioned this, but the reverse reaction can be sped up even more by raising the temperature of the KCl + Na solution, because the forward reaction is exothermic. So you end up using Le Chatalier's Principle in two ways: removing a reactant, and increasing temperature.

Brendan Donnellan - 2020-11-15

Great to see your back inspiring the world with this kind of science Cody.

Thomas Davis - 2020-11-15

Looking really well Cody, keep making videos, we all love them 😀

Ryan Schenk - 2020-11-16

Fascinating stuff! I always love seeing new Cody videos in my feed! With everything that's been going on, this year really has been more fun and interesting thanks to your channel! I really appreciate your work! Thanks, Cody!

Sauspreme - 2020-11-15

Love these videos. Out of curiosity, what do you think happened to the rest of the yield? did it just stay behind or leak out or something? Since it didn't dissolve into the tin

Felixkeeg - 2020-11-16

I'm in awe of how well this actually works! Really impressive work, Cody

Hobo Sullivan - 2020-11-16

That's very impressive. Somehow, I missed your previous alkali-metal distillations (I'll have to hunt those videos down). But this apparatus is pleasantly simple and elegant. That liquid seal was an especially nice touch. And it's hard to argue with results like that, as they say.

ChaosPotato - 2020-11-15

This is really cool. Don't breathe the smoke too much though

realedna - 2020-11-16

Great video and actually genious concept with an elegant setup. There are only minor things left to improve now! Keep up the good work. :D

VarionJimmy - 2020-11-16

Another great video from Cody!
Perfect ending of the week.
By the way: I’ve always LOVED the music in the beginning and end of Cody’s videos.

Tobias Whittaker - 2020-11-17

Hey cody, long time fan here, just want to say we all really appreciate the effort put into your videos. thanks man!

Gregory Kayl - 2020-11-17

Love these style of videos. I’m glad you’re doing these again! Keep the awesome videos coming!

Ra Serves The Dinner - 2020-11-15

Seeing Cody cheerful in the introduction made my day. And great content as always.

Les Hemmings - 2020-12-01

A splendid result Cody! Plus, fascinating to watch. Thank you for the most interesting 20 minutes of my day. 😃
