9:48 "my professor sometimes watches my videos... I can't include this" 💀💀💀💀
DF6CE? Sieht aus wie ein Rufzeichen ;-) 73 de dk4amf
includes this
10/10 scientists agree that saying "now it's safe" increases the safety of the experiment by 10%
Say it 10 times to make it 100% safe
@yanniking7350and always wear some Safety-Flipflops.
@MatzeMaulwurf Just shake your foot if you spill acid; it makes it shake off.
@yanniking7350No, danger level just becomes 90% of the orignal, decreasing exponentially but slowly, and never becoming zero.
Survival bias
watching this as a chemist I felt like as if I was in the funniest nightmare
Same, You know what they say. Safety Third!
Watching this as a physics student. I feel a little more grateful for my calculus
@adamfuhrman Third seems too high up the list for something as trivial as safety in this video.
wachting this as a chemist I wish I had unlimited money and the drive to do stuff like this. Seems like fun.
Right! At that spurt of fire, I literally said, shit! and damn near dropped my phone. These 2 are crazy. He clearly has access to a lab, or a friend's lab, use it! Lol
💥“…Now it’s safe.”💥💥”…Correction. NOW it’s safe.” 🤣
Like the evacuation scene in Austin Powers.
You keep using that word. I do not think it means what you think it means
During the whole scene I was imagining them speaking german xDDDDD
@czn_foxy6869 Es sind ja auch Deutsche!
What's the timestamp?
One step closer to a full-size self-igniting cesium flamethrower!
😂
I will put that on my to-do list.
@AdvancedTinkering I wonder what level of war crime that would be.
@andytunnah7650Vermutlich das selbe wie der Einsatz von weißem Phosphor...
@andytunnah7650 "Yes" Level.
12:20 Elias’ unwavering confidence is so funny when he is instantly contradicted
Now it's safe!
Just when I was thinking of making 1.5kg of Cesium, this video popped up! Thanks Mr Tinkering.
That’s why I made these videos. To solve everyday problems.
Maybe you should consider making around 3kg to get your 1.5kg in the end. 😅
@realedna We're going to corner the Cesium market hehe. Just need to find a use for the stuff ...
@giddy9052 Refilling atomic clocks?
That's why I decided to make 2kg of cesium. I figure if 1.5kg is dangerous, I better stay away from that number. Presumably, the further away I get from 1.5kg, the safer it will be. So, really I should be going for like 10kg here. I mean, I can't very well make -8.5kg of cesium... unless I start with cesium and consume 8.5kg in a reaction. I guess that would be like "making" -8.5kg.
I don't want to do this in my lab, let's use Elias's kitchen instead.
Elias seems like a really good lab partner. He has a great sense of danger, and correctly predicts everything that can go wrong. As long as you negate every statement.
golden comment. the way everything he says won't happen immediately happens and vice versa
Please tell me your professor didn’t know you were doing this, and then you told them by walking into the lab with the briefcase full of cesium.
The amount of times you went "it's fine" just moments before disaster is perfect comedy.
Filming this project with you was such a blast! I hope we can do a lot more projects like this together in the future! ;-)
It really was! I had so much fun :D Thank you again!
And I’m certain there will be more projects together ;)
Please make more videos, dein Humor ist Weltklasse. Hast du das Stinkspat Video gelöscht und warum?
There were indeed many blasts in this video ahaha
Do you guys wash the dishes at home yourself? Or do you allow your wife to do it too? 😂😂
A literal blast 😁
12:15
"Man soll kein Vakuum auf Flachboden ziehen"
"Ja aber ich glaube die können das ab"
Berühmte letzte Worte. 😂😂😂😂
Der Blick kurz vor Katastrophe war gold 😂
Es soll Leute gegeben haben, die sich fragten warum sie in einem Krankenhaus aufgewacht sind, so mit Apparaten, Verbänden usw., einige Wochrn nachdem sie einen Elenmeyerkolben an einem Rotationsverdampfer angebracht hatten..........
@benjaminhampel8640 Ach als ob. Jeder Böller knallt heftiger.
Wenn sie alten Ether abrotiert haben vielleicht.
@christiannorf1680 Das wurde mir auch nur erzählt, als ich Lehrling war im vorletzten Jahrzehnt.
Saugflasche, Erlenmeyerkolben...wenn man nicht genau hinschaut sehen die von der Form gleich aus 😅
Here starts the "NOW IT'S SAFE" meme...
fr. now its safe
The glass-blowing part was so cool! I'm so glad you included it
I’m happy to hear that you liked it! I was really undecided on whether to include it or not.
Definitely I would like to see more glassblowing in the future!
So was the glass-blowing-up part 😂😂😂
I share the same sentiment
21:50 the "stfu look" 😂
For reals
"Do as I say, not as I do" is probably the most important thing for a chemist to say
Youtube had some nerve hiding me from this for 1 minute
ikr
I had to wait 2 whole hours!
@ScavengerDLC Same
@ScavengerDLC same
@ScavengerDLC3 😭
3:00 that stainless steel looks awfully stained
less than normal steel would be! 😂
Why he fondling it like that tho
I mean, it’s stainLESS not stainFREE steel.
Stained with SCIENCE!! 😭
NileRed is cool and all, but your channel goes so in depth with the science and chemistry while still managing to be easy to follow. Plus your amazing German accent adds +10 mad scientist vibes!
NileRed is extremely annoying. Can’t stand anything about him.
@konorkolerhe’s a goof and doesn’t take things seriously enough
@konorkoler his camera man pisses me off
@Gizmos_and_stuff Not sure why you feel that way. His camera man is one of the nicest people I have ever met.
I really appreciate hearing that you enjoy my videos!
A glass blowing LATHE? It's all the things my shop teacher wouldn't let me touch combined!
12:24 Oceangate
The cesium stalagmite formation is really beautiful.
Looks like a lot of fun to work with "it's safe now" Elias! 😁
Legend!
From someone with a pastry cook past, ovens tend to keep moist air inside despite the heat. I like to keep the door opened up a little with something like a spoon or spatula when I want to finish cooking "wet" pastry doughs such as choux.
A tray of desiccant is my usual go-to when drying stuff in the oven.
Interesting fact! Thanks for letting me know.
I recently got a used vacuum oven, which is probably the best way to dry something like this.
@AdvancedTinkering residential electric ovens tend to be sealed, whereas residential gas ovens tend to be vented to let combustion gases escape. The upshot is that despite producing water as part of burning the gas, residential gas ovens frequently have lower humidity than their electric counter parts. This can be noticeable when cooking/baking. Of course, both types of ovens are suboptimal when used for chemistry experiments.
Just one more 'It's save, bro' and the procedure will work flawlessly, trust me.
The water pouring out of one end while the other was on fire was amazing
Forbidden sand and forbidden gold
i refreshed my page and found this, epic find.
wow, you're right, cesium is absolutely beautiful
I am so tired after full week, that the sentence "what exactly the smoke consists of is unclear" absolutly broke me ;)
Super cool tower of cesium . Now its safe had me rolling 😂👍 👍
I swear, you guys need an engineer to make some of these setups not so terrifyingly unsafe. I barely understand how orbitals work, but the shenanigans in this video make me fear that your insides will soon be on the outside.
That being said - holy crap this is cool!
Oh trust me, they are being pretty safe for "amateur" chemists. They are implementing professional techniques on a budget. If you want to see how it looks like when somebody without proper training does chemistry, check Mr.Greenguy.
How do you only have 1 mil subs, this is one of the best chemistry channels on YouTube. Like who else does this?
Thank you so much! I really appreciate it!
I think, the algorithm got to know about him two years ago, when he worked on his turbo pump. I bet he is going to keep growing for a while.
T-shirt idea.... an "it's safe now" scale....with varying facial expressions from your experiments lol.....probably gonna be a long t-shirt 🤣
The finished ampules with Cesium are so beautiful.
Advanced Tinkering: Oh, Shit
Maniac in the Background: Yes, Danger
🤣
The Cesium tower was great.
Elias‘ funny and calming fatalism is always the cherry on top. „Nah nothing bad happend, it’s okay“ 😂😂😂😂😂😂
25:32 wear a damn respirator. you REALLY do not want to breathe in that dust
And with all the smoke being made too
16:10 sure looks like a big tray of brownies.
14:29 You probably already know this, but if you didn't: Those clamps can also be tightened via a standard 7 or 8 size hex socket (or whatever they're called)
9:38 baloon dysfunction.
This was extraordinarily funny – I love the raw behind-the-scenes footage.
Producing 1.5 kg of the most reactive metal on Earth and casually calling it “not smooth” is wild! 🤯
This seems wildly dangerous and i totally support this for science
20:53 excellent observation! I certainly agree that the smoke consists of something that isn't clear, as it's not very easy to see through it :p
Vor diesem Video kam eine Werbung für Hausratsversicherungen, ich beginne zu verstehen warum.
Hahaha ich stelle mir das Gesicht des Versicherungsmitarbeiters vor während ihm erklärt wird was passiert ist 😂
Cooking lithium on a hotplate, and stirring it with an electric whisker is cracked already...
But on the "What happened to argon and schlenk?" I almost choked.
For the next run whenever Elias says it’s fine, assume it’s not 😅
@FreddieStarWars - 2026-02-27
Two chemists going "Oh shit, oh fuck" is terrifying
@AndreasW-c7i - 2026-02-27
it is the natural response of every true chemist and actually required by law
@marluna_x - 2026-02-27
Them being German makes it 10 times more terrifying
@vanillaicecream2385 - 2026-02-27
when things go so badly germans start swearing in english
@custos3249 - 2026-02-27
Especially if it's their honeymoon
@LaLaLand.Germany - 2026-02-27
No. That´s when the fun begins.
