- Most of you have already seen Cesium being dropped into water. But I am sure, no one has seen cesium being dropped in liquid oxygen. It is the most spectacular reaction, involving cesium, I have ever seen!
The experiments were done in a safe location and under strict safety precautions. They are for educational purposes only and should not be repeated!
Go and check out Elias Channel (its great!): / eliasexperiments
Do you have any suggestions for other reactions involving cesium? Let me know in the comments.
If you want, you can join my patreon to help me working on my projects. I would really appreciate it!

can burning cesium react with carbon dioxide similar to magnesium? (Cs on dry ice)
couldnt find anything on the web
@@TheRolemodel1337 We will try it in the future.
I agree, it was a lot of fun performing these experiments with you, and I hope we can continue doing stuff like this together in the future!
I feel like the German government doesn't really appreciate you...
Where's Tom from Explosions&Fire when you need him? He does make an excellent point about using plastic cups instead of glass beakers for this kind of work! 🤣
Absolutely extraordinary stuff. I've certainly never seen liquid cesium liquid oxygen reactions before. I've been following the progress in understanding the strange nature of alkali metal water explosions since seeing that first classic cesium-water reaction shown in a BBC Open University documentary in my high school chem class in the 90s. Nothing made sense about the conventional explanations everyone gave back then of simple evolved H2 explosions and the revelation of Mason et. al. work in 2015 that it was a coulombic explosion complete with blue solvated electrons was totally amazing. But here, we may be back into mystery territory. That last shot you have here of the 4g Cs liquid into the LOX shows a TRUE DETONATION. That is absolutely not a deflagration, I can see the shock front distorting background imagery on the frame by frame. What is causing it?? Is it really just rapid oxidation with the O2? Did the small amount of mineral oil cause a conventional hydrocarbon-LOX 'oxyliquit' detonation?? Is it a coulombic detonation with the Cs again, and if so how does that work in LOX? Many questions. I would definitely love to see a repetition of the experiment done in an unsilvered Dewar flask with an ultrahighspeed camera (at least a Chronos, but preferably a Phantom) so the frost on the LOX container isn't an issue.
Wonderful thoughtfully conducted interesting investigations.
Yes, there are many unknowns. If we get the chance to use a high speed camera, we will try to film it on a small scale in a dewar.
@@AdvancedTinkering Next level chemistry research and education. Thank you very much for sharing! You are a very accomplished researcher already at that young age.
@Muonium1 I agree 100% 👍
It took me a few seconds to realize, "Wait, where's the beaker?"
That reaction is remarkably energetic. Thank you for doing this safely!
You and ChemicalForce should do a Cesium video together, I feel like that would be the perfect mixture
He has some awesome high speed equipment too. Also, I wonder if the Slo Motion Guys would be interested. They don't do too much chem stuff but have the best high speed cams.
@@LFTRnow they actually rent the cameras for their videos as they are too expensive to own.
found you on the Reddit post haha, cool video. subbed
Thanks! I really ppreciate it!
That beaker was just vaporized, amazing, can't wait to see the other experiments
You know I recall thunderfoot doing full proper lab experiment getting high speed footage of other metals going through the reaction here. It is really fascinating stuff the more you look into it and how this reaction is taking place.
What would liquid ozone and cesium do? Anyways, great video!
Liquid ozone is terrifying by itself.
Glad no one got hurt, that last clip was INSANE!! such an immediate and absolute explosion!
I litteraly just watched that fake video yesterday in class! Thanks for showing me the reality!
Nice. Would love a brief explanation of the chemical reactions involved too
However there is some questions concerning the last reaction - the oil itself could have contributed the MOST part of energy release, while being ignited by cesium ! It is very well known to keep away oily stuff from oxygen cyllinders for a reason! If you ever repeat this stuff please make sure only metal reacts to get the true picture. Good video btw.
Thanks! Yes the oil definitely had some effect. I would guess, that the fireball was mainly caused by the oil. But I don't think it contributed the largest part of the energy released. If you watch the parts where we dripped small drops of cesium into the beaker, the energy released is impressive. And those drops are probably 0.05 mL at the most. And there is no oil present.
But if we do it again, we will try do to it without the oil.
@@AdvancedTinkering honestly I don't mind the oil. The fireball looks cool 😁
@@AdvancedTinkering And - what might be even more important - Cs has not a very high energy density because of its high atom mass. Sodium has almost three times the volumetric energy density. But of course, sodium isn't liquid at room temperature. But Na2K is. And the alloy has over double the energy density compared to pure Cs.
Liquid oxygen is such a lovely colour of blue.
Love it
Did you use a medical oxygen concentrator and your cryocooler to make the LOX? In another video of yours, I recognized the blue O2 concentrator 😄 That's the exact machine I use with my Stirling cycle cryocooler to make LOX. But reacting with CESIUM!??? I gotta hand it to you Germans, you do the most spectacular things!! The best thing I did was dropping lit candles into LOX.
Me, living in Germany and being afraid to change oil in bike by myself (because neighbours call the Firefighters). These guys: doing experiments with cesium on back yard... In last try explosion could also be amplified by mineral oil since almost everything that can burn also can explode in LO2
If only fluorine wasn’t such nasty stuff because I would love to see how liquid fluorine compares with liquid oxygen seeing with fluorine being an even more powerful oxidizing agent than oxygen and oxygen is a pretty powerful oxidizing agent in on itself! 🔥
I have just received my order of metal elements and I want to start the experaments - but safety first
6:56 What about somebody who lives in Germany but doesn't have a high speed camera but a chemistry degree, and would really like to see some cool experiments in real life? 😛
Very cool video!
I can't believe Brainiac lied to me, i may never trust again.
In the 1990s my friends and I stole about a half pound of cesium from our high school science department, and dumped it from a bridge into a canal. It was a lot less violent than we expected, but for a brief moment we could see the floor of the canal (maybe 5 feet deep).
Great content AGAIN ... last one have power of metal device on the wooden stick with rope inside ... (no kidding) many thanks
Perhaps next time plastic cup type containers instead of beakers, much less energetic shrapnel and you don't wind up with broken glass all over the ground.
Of course putting lox into a hydrocarbon container has its own risks lol.
Yes, a plastic cup would have definitely been wiser. We spent quite a while collecting all the glass.
@@AdvancedTinkering lol, Hey I replied to your email about making things BTW but I haven't heard back. Did it go to spam again? You might need to add me to the whitelist or something
Have a Keyence "high speed" camera, it is not very high speed but it works.
Jeez that was a big explosion , impressive !
exploding glass next to a playground?? wtf!
It's was Dioxygen ?
You should totally try this with NaK, and if you're insane enough do it with ozone
Not sure if I missed it if it's already been done but I'm curious what cesium in liquid ozone would be like and if it would even be different than lox.
That actually is on out to-do list. But we haven't had the time to do it yet.
@@AdvancedTinkering Be careful!
Liquid ozone can detonate on it's own!
Just read John Clarks entry on it in 'Ignition' if in doubt....
,,Stay Scienced by RL Science,,auf TH-cam hat eine Highspeed Kamera aber er ist in letzter Zeit recht inaktiv geworden, deswegen muss man mal schauen ob du ihn erreichen kannst. Aber seine Shots mit der Kamera waren recht gut.
Btw ich liebe deine Videos, und ich finde die so interessant, informativ und spannend das ich gar nicht versteh warum ich dich jz erst gefunden habe 😂
The Slo-Mo Guys have come several times to the USA for special projects, so maybe ask them to visit you?
the Cesium in mineral oil reacting with the liquid oxygen is basically a fuel air mixture bomb like a Russian thermobaric bomb.
Yes, we want to repeat this experiment without any mineral oil present. Curious to see if the violent reaction was mainly due to the mineral oil. But I doubt it.
@@AdvancedTinkering There's simple no way that it didn't: you've mixed liquid fuel with more than enough oxidant to burn it than you gave it activation energy.
The mineral oil definitely reacted. But considering the violent reaction when dropping pure cesium in liquid oxygen and the fact that there was only a very small amount of oil covering the cesium, I think the reaction wouldn't look much different without the oil. You probably wouldn't see a fireball though.
We will see when we repeat the experiment.
Why use glass containers and not a steel tank or other metal?
YOWZERS!! Is that a Coulombic explosion?!
Makes me wonder if the reaction between caesium and liquid ozone would be even more violent, though tbh I don't know how you can get much more violent than the reaction in the video...
We already thought about testing this.
@@AdvancedTinkering I've never seen liquid Ozone. I would like to see it just to see it. It's very toxic.
Glass beaker probably wasn't so great idea! Great video anyways!
Yes, in hindsight the glass wasn't a good idea.
Great video.
Thanks for this video. I was wondering if you’d be able to carryout a reaction between liquid oxygen and a MOF(metal organic framework). Thanks!
I do not have any MOF have access to it. If I ever get the chance, I will try it.
Wouldn't it be simpler to just omit the annoying acronym?
Sorry you waited a year for this answer: no.@@MadScientist267
Question could the extreme outcome in the " fake" reaction be because the cesium was fully submerged when exposed to the water rather than being dropped on top or into it raw. I ask because wouldn't it being properly submerged cause more of the cesium to react.
The reaction in the brainiac video is definitely faked. Yes, the reaction would be a little more violent if the vial is completely submerged. But nowhere near like it was shown in the video. There is a video from periodic videos where they crack a vial underwater and you can see the difference.
It is the excess electrons getting ripped from the cesium atoms via conductivity and "flowing over into the oxygen that gets reduced.
The flow of electrons is basically like an electrical explosion and then the hydrogen evolves can also react, but in this case gets blown away as it's a much slower reaction to liberate final hydrogen gaseous product.
Id love to see what happens if you mix cranium with flouroantimonic acid
How about cesium and flourine?
I wanna see every one put together at one time some how like all the ones you just showed lol
Make a seal metal container to hold the reactants!!!
@6:00 - Does liquid oxygen actually look slightly blue or is that the camera?
It indeed does look blue in real life.
Wow you are getting true detonation with some of these reactions 😲
Cesium + halogens?
There will be a video about that ;)
@@AdvancedTinkering Keep up this spicy content and expect your subs to greatly grow.
4:16 600 milliliter beaker condemned to death? 4:23 Sentence carried out 7 seconds later!
Did the authorities know before or after the experiment?
Yes, it was a registered event on the premises of an institute.
What about arranging a collaboration with the Slow Mo Guys?
kekw
Never before done on TH-cam. OMG Alert the media!
Try contacting ( THE SLOW MO GUYS )
Imagine being a kid running around there afterwards lol
The fact that Jeremy Hamster allowed that lie to go on air will prevent me from ever trusting him about anything again.
Where is the phrase "we have more tables"? Without it, it's like James Bond movie without "Bond. James Bond".
Good, now mix liquid fluorine and cesium
A lot of energy of the explosion is actually in the oil
Reach out to the slowmoguys ❤❤
For added fun, why not react caesium with fluorine?
Cesium and liquid fluorine. Better still, cesium and liquid hydrogen
I got 10 liter bucket of Cesium 137 in my basement so i must try this... :D :D :D
To any 3 letter agency, this was a joke. Please do not SWAT my home...
1:34 this guy has carbon tetrachloride?!
Contact the Slo Mo Guys (UK/USA). I am certain that the email subject "Let's Explode A Lot Of Cesium In Slow Motion" will get somebody's attention.
The problem is, that we definitely can't travel with the cesium and other chemicals. And I doubt they would fly to Germany to film it. But it may be worth a try.
@@AdvancedTinkeringNothing ventured nothing gained. I sent them a link to your video because .. why not? ;)
Just thinking of being out in the backyard walking around, barefoot finding pieces of glass
It's not a backyard ;) It took us a while but the whole area was cleaned afterwards.
Frag doch mal jörg Sprave vom Slingshot Channel ob er mit der chronos vorbei kommt. Bei Explosionen sagt er bestimmt nicht nein.
Ich bezweifel, dass er sich noch mehr Ärger mit den Sicherheitsbehörden einhandeln will. Ich glaube es wäre auch generell schlecht für sein Image wenn er Explosionen auf Kinderspielplätzen herbeiführt.
Es handelt sich um das Gelände eines Instituts und die Versuche wurden im Rahmen eines angemeldeten Chemie-Workshops veranstaltet. Hatte also alles seine Richtigkeit.
@@AdvancedTinkering Hör auf dich selbst zu belügen. Mag ja sein, dass ihr das dort irgendwie als Workshop angemeldet und genehmigt bekommen habt, aber das Gelände welches offensichtlich als Kinderspielplatz dient mit Chemikalien und Glassplittern zu verseuchen ist eine Schweinerei. Sucht euch einen passenderen Ort mit Betonboden/Fliesen, so dass ihr alles ordentlich zusammenkehren könnt wenn ihr durch seid...ein Ort an dem keine Kinder spielen.
The cesium is too reactive therefore the cesium jumps out of the water
Cesium with Chlorate and Perchlorate. You can make the Chlorate yourself if you dont have any.
Nices Video aber am Spielplatz testen hat was😂
Ist kein Spielplatz sondern das Gelände eines Instituts, dass Seminare für Biologie und Chemir veranstaltet.
What if you reacted cesium with ozone?
Ozone has a nasty habit of exploding on it's own in liquid form anyway.
Ach du Scheisse. Das war heftig.
next step, liquid ozone....
When you add oxygen to your oxygen to get more oxygen per oxygen.
Did you inform yourself beforehand if it's allowed in Germany to perform such explosions without the according license?
I spent some time studying the law regarding this topic. And as far as I understand, it is not illegal as long as it is done without endangering others, since it's not an explosive.
Would be comparable to potassium being thrown into water or the reaction between hydrogen and oxygen in a balloon.
@@AdvancedTinkering O.k. thank you.
What about using the 30 % H2O2: is this possible via the business you registered for your monetized channel?
But carbon-tet is banned worldwide afaik - even for commercial uses...
None of those chemicals are mine. I just brought the cesium. You would have to ask elias about that. But as far as I know, the possession of 30% hydrogen peroxide is not prohibited. Only selling it to privat individuals.
Same goes for carbon tetrachloride. I think producing, selling and using it is prohibited. But the possession is legal.
But I could be wrong about that. I never looked it up in detail because I don't need or use any of those things.
@@AdvancedTinkering H2O2 in conc. higher than 12 % is illegal to possess or use for private persons according to the EU regulations for precursors of xplosives. If Elias has no registered business he better shouldn't show it on YT... 😉
TCM is worldwide banned by the Montreal-protocol already since 1999 - only research institutions are still allowed to use it.
@@experimental_chemistry Sale of these items is already extremely regulated, if someone can manage to get it then it's pretty much always legal.
3:11 Wenn Chemie doch nur immer so klingen könnte.
what a mess in this nice garden spreading glass around.
….lol?
Habt Ihr das alles echt auf einem öffentlichen Spielplatz gemacht? Da laufen doch bestimmt Kinder Barfuß rum, ist schon gewagt, wenn da noch Glassplitter landen könnten :/
Kein öffentlicher Spielplatz, sondern das Gelände einer Institution, die Workshops für Chemie und Biologie veranstaltet. Es war eine offizielle und angemeldete Veranstaltung.
@@AdvancedTinkering Im Hintergrund sah das so nach Spielplatz aus, weswegen ich besorgt war. Vorallem babys watschen ja immer Barfuß herum.
If you think that that is exciting try Cesium and Fluorine
Ist das da alles dein Privatgelände? Es sieht in manchen Szenen eher aus wie ein Park oder Spielplatz.
Nein, das Gelände gehört nicht mir, sondern einem Bildungszentrum, das auch Workshops zum Thema Chemie und Biologie veranstaltet. Dort wurden die Versuche als angemeldete Veranstaltung durchgeführt.
@@AdvancedTinkering Das Zentrum wird dann offensichtlich von sehr verantwortungslosen Personen geführt wenn es überhaupt stimmt, was ihr da sagt.
Warum machst du keine deutsche Videos auf TH-cam?
Ich möchte mich gerne mit der internationalen Community austauschen. Und das geht nur auf Englisch.
@@AdvancedTinkering Achso ok
What kind of location is that? Looks like a childrens playground that you're contaminating with glass shards and chemicals. 🤨
It is the property of an institute. The experiments were carried out as part of an event, and all glass pieces were subsequently carefully removed.
@@AdvancedTinkering Right...all glass pieces were removed...for sure.
To be fair, the original video was made in Britain. So it's pretty honest by their standards.
Glass doesn't show up on x-rays. It is always irresponsible to put energetic material in glass containers. Don't set examples like this please.
I wonder if that's a deflagration or detonation
