I again met with Elias from Elias experiments to test the reaction between cesium and chlorinated solvents. Check out Elias Channel! It’s worth it! https://www.youtube.com/c/EliasExperiments Jetzt auch mit deutschem Untertitel! Now with german subtitles! If you want, you can join my patreon to help me working on my projects. I would really appreciate it! https://www.patreon.com/AdvancedTinkering
First! I had a blast doing these experiments with you! I hope we can do a lot more awesome stuff like this in the future! ;-)
Yes, definitely! I had a great time and I think there will be a lot of awesome projects for us to do!
Haha loved the little Grimace reference
Great video! The slo-mo looked great! I never knew such power could be achieved from so little caesium and chloroform
I know a certain chemist in Australia who would love that huge bottle of Carbon Tetrachloride lol
I love the Napoleon Dynamite reference at the start, as well as "drying bromine with caesium". :)
Thank you for the excellent video!
You're welcome! I am glad you liked it!
Cesium plus chloroform makes a true detonation. Im guessing the reaction is hot enough to easily boil the chloroform to a cloud of vapor then the boiling hot cesium reacts. Sora like a mini thermobaric explosive. To shatter the metal beaker like that it definitely had respecable Vdet as well. Good to see you doing these energetic reactions safely. 🤓❤
Super fun. Super well done.
Thank you!

Grimace... it spreads
Fuckin love Grimace
Putting stuff together going boom is fun. But can anyone line out the reaction in detail? And the explanation for the time delay?
It would be nice if you could explain why this is happening, and why there is a time delay and also the reaction formulas. Also why is that Lead stuff such a dangerous chemical.
There's no lead in, but CCl4.
If I understand it correctly the bottle was part of a collection of analytical reagents.
CCl4 is carcinogenic, but has been phased out mainly due to ozone depletion. Chloroform is almost as bad, but still is widely used for a HPLC solvent. 🤓
were you thinking about trying to pour solvents into piranha solution?
Man hört es sofort aus dem Akzent raus das du deutscher bist haha, sehr interessanter Kanal bisher , keep growing ✌️
Ertappt! ;) Danke! Freut mich sehr, dass es dir gefällt!
Have you tried this reaction with sodium or other alkali metals? I'm curious because you got much more violent results than Tom from explosions and fire when he tried this.
Elias tried it with NaK and Carbon tetrachloride and it was a very violent reaction. But he had to drop it to start the reaction.
It makes sense that cesium reacts without having to drop or hit it since it's the most reactive alkali metal.
Interesting, I wonder if liquid metals react better due to higher surface area.
With the ozone depleting, cancer causing chemical, the explosion had an amazing texture. It looked like it was made from thousands of fibers or strings, that almost looked like they had a solid form for a moment I’m the slow motion. I didn’t see that same effect with the chloroform, or any of the other examples. What causes this?
CCl4 would be reduced to carbon. Chloroform would be reduced to acetylene which would decompose and ignite. I guss this would be the most entertaining way to make cesium chloride 😁😅
Besides, if you bring some of those bars of camping-tents in contact with instant glue, it starts to smoke causticly and faster than that your eyes would start to sting even at some distance!??
Who are you, who are so wise in the ways of science?
"What manner of man are you, that can summon fire without flint or tinder?"
So can anyone explain what’s going on here? I guess the Cs is ripping off the Cl for itself, and sending the rest of the molecule to Hell really fast? I’ve never seen such a violent reaction of Cs, even with pure Cl2 gas alone.
Yes the main driving force is the formation of CsCl. There are quite a few products that can form. For example HCl, carbon and radicals. In this paper the reaction is discussed: https://doi.org/10.1016/j.jhazmat.2018.12.097
In my opinion the reaction between Cs and liquid oxygen was a more violent. But maybe it just seemed that way because of the huge volume of oxygen gas being produced due to te reaction heat.
Grimace lol
Das ist heftig. Ich glaube, man kann berechnen, dass wenn direkt CsCl ensteht, die freiwerdende Reaktionsenergie der Gitternergie entspricht. Das ist wahrscheinlich wirklich viel, wenn man den hohen Schmelzpunkt von Alkalisalzen bedenkt.
That's tough. I believe one can calculate that if CsCl is produced directly, the reaction energy released corresponds to the lattice energy. That's probably a lot considering the high melting point of alkaline salts.
Does a reaction between fluorine and cesium the produce the highest chemical energy possible?
If not, what does?
That would be something like fluorine and beryllium or something like that.
Hey gibt es diese Filme von dir auch in deutsch ?
Hallo,
Leider nicht. Aber manche Videos haben einen deutschen Untertitel.
Nice video! Can you send me an email, it seems I cannot find yours in my inbox ... Anyways, I have some insights to share on the "Staudinger" explosions and also Staudinger reported that Na does not react with Br2, can even be boiled in it, while K and Br2 react at once. However, he writes, that a small shock leads to explosion in the Na + Br2 case. Thus, in all these explosions of organochlorine, -bromine, -iodine compounds, the mechanic shock seems to trigger the explosion. In the past, we explored if perfluoropolyether would react with Rb. It does not at room temperature and not under boiling. When we put the mixture in the sonicator, we got explosion. I always thought it must be due to the increase of surface area, similar to Staudingers thoughts, but now it is not so clear...
try Cs with perfluorocarbons
Impressive - but are you really quite sure that you don't need a pyrotechnics license for experiments of this caliber? Or was it part of an official university project? 🤔
The way I understand the law (§ 308 “Herbeiführen einer Sprengstoffexplosion”), it is not illegal as long as you do not harm anybody or damage any property. If you have any more information, let me know.
@@AdvancedTinkering
The StGB is one thing, the Explosives Act (SprengG) is another.
Do you have that in mind too?
Here are the relevant places:
"Gesetz über explosionsgefährliche Stoffe (Sprengstoffgesetz - SprengG)
§ 3 Begriffsbestimmungen
(1) Im Sinne dieses Gesetzes sind
1.
explosionsgefährliche Stoffe:
a)
feste oder flüssige Stoffe und Gemische (Stoffe), die
aa)
durch eine gewöhnliche thermische, mechanische oder andere Beanspruchung zur Explosion gebracht werden können (...)
3.
pyrotechnische Gegenstände: Gegenstände, die explosionsgefährliche Stoffe oder Stoffgemische enthalten (pyrotechnische Sätze), mit denen auf Grund selbsterhaltender, exotherm ablaufender chemischer Reaktionen Wärme, Licht, Schall, Gas oder Rauch oder eine Kombination dieser Wirkungen erzeugt werden soll, (...)
§ 7 Erlaubnis
(1) Wer gewerbsmäßig, selbständig im Rahmen einer wirtschaftlichen Unternehmung oder eines land- oder forstwirtschaftlichen Betriebes oder bei der Beschäftigung von Arbeitnehmern
1.
mit explosionsgefährlichen Stoffen umgehen will oder
2.
den Verkehr mit explosionsgefährlichen Stoffen betreiben will
bedarf der Erlaubnis."
What is considered an explosive or pyrotechnic charge is often up to the judgment of the adjudicating judge.
As soon as self-made flammable mixtures of strong reducing and oxidizing agents are found, proceedings are usually initiated for violating the Explosives Act.
Energetic mixtures are generally a problem in Germany.
Anything beyond popp gas testing and small-scale iron thermite can become a problem once someone is bothered or threatened by it - and unfortunately there are always people like that on the internet...
With regard to me, I can give the all-clear: I am on your side - and therefore on the side of freedom of research and science.
Nevertheless, one must unfortunately say: if someone in Germany wants to avoid legal trouble, they probably have to give up experiments like this - sad, but true... 😢
Who cares? He isn't harming anyone or anything.
Thank you for the additional information!
@@user255
In Germany, you are also punished for violating laws if nothing and nobody could come to harm.
In legal terms, this is a so-called victimless crime. Or in other words: it's all about the principle.
If you then do this publicly, it may only be a matter of time before you are summoned for a hearing or your house is searched without prior notice...
Between 2005 and 2008 there was a wave of searches of 2000 households just because a chemical dealer sold what he shouldn't have sold...
In Germany, the state's attitude towards dealing with chemicals is a bit like paranoid... 🙄
Wunderschön
Danke!
Woher habt ihr denn CCl4?
Sieht nach geerbtem Altbestand aus.
Ansonsten gibt es auch noch einen polnischen Händler...
Eigentlich soll laut Montreal-Protokoll aber niemand mehr ausserhalb von Forschungseinrichtungen und Universitätslaboren das Zeug noch verwenden dürfen - in allen Unterzeichner-Staaten weltweit und schon seit über 25 Jahren!
@@experimental_chemistry Auch an meiner Uni wird darauf, wenn möglich, drauf verzichtet, deswegen wunder ich mich woher die das Zeug haben und so relativ léger damit umgehen.
@@tschadschi1010 "Léger", ist das ein franzosische Wort?
Wher cam you fro germany or English
Germany.
@@AdvancedTinkering dachte ich mir schon
Hast du ein par experiment was man mitt salpeter machen kann
Nicht wirklich. Experimente mit einem einzigen Stoff zu machen ist immer schwer. Du könntest versuchen Kristalle daraus zu züchten.
@@AdvancedTinkering naja kanst ja auch experiment mit salpeter verbindungen machen aber danke für den vorschlag
To me it looked like the solvent was dried.
Dried, fried and evenly dispersed.
I wanna see hexachloroethane vs caesium. Sure it's not a liquid but still.
I unfortunately don't have hexachloroethane. If I ever get some, I will test it.
Wierd. Triclouro methane is clouroform. İ always had in my mind that cluoroform was tetracluoro methane or CCl4 . İm ignorant.
You' re not my real dad? Am I being adopted?
Lösen sich eigentlich Salze in Cäsium?🤔 Wenn ja, dann probier mal NaCl, Natriumhypochlorit und Natrium Perchlorat und das ganze mit den entsprechenden Kalium salze und Ammoniumsalze :D
Crazy germans.
