Is Cyclo nitrasil more dangerous than Nowitchock? Very suspicious...
Has the Professor an alibi for the time of the Skripal attack?
Surely the absolute most terrifying is Chlorine Triflouride
The guy at the end was playing with alien acid blood.

What's the most dangerous chemical you've ever handled?
"I dropped it"
“This is why we can’t have nice things” says the Skeletons of the other scientists
🤣🤣🤣🤣
😂😂😂😂
The most dangerous chemical I've ever handled was bromine. There's no fume hood or whatever the name is, so I only depend on where the winds blow. During one of experiment of proving of covalent bonds of fatty acid, I did this experiment near the window, but the wind were not in favor. Instead, the wind blew to inside and some fumes enter my lungs. Felt a bit of hurt in lung and uneasy for two weeks
On the video about TNT he talks about hitting nitroglycerin with a hammer
His hair is enough credibility needed for me
Yep. Einstein lives!! Lol!
Would you ever give him something fragile/delicate to handle? LOL
Can I see your qualifications, shows driving license. Say no more.
Someone give him a delorian so we can get time travel sorted.
me: mom can we get einstein?
mom: no we have einstein at home

Drop the bottle
Chemical : " Hi, my name's NiNOOOO !!"
I understood that reference lol

Happened once before. I got the pictures to prove it
This mess would be hard to clean. Even for NiNO

British accents and chemistry seem to go together nicely.

There's no such thing as a British accent old fruit cake, it's everyone else who has an accent.
A German accent makes it sound more deadly.
I always thought a German accent suits better haha
@@jamesrindley6215 So you're saying that British people don't pronounce words? Because that's the actual linguistic definition of an accent-a distinctive mode of pronunciation. Every single speaker of a language has an accent of that language.
1st guy: most poisonous chemical
2nd guy: highly flammable chemical
3rd guy: chemical that turns air into sulfuric-acid
I think I'll stick with computer engineering, thanks
Andrew Halverson
1st profession: Potentially life threatening
2nd profession: Have no life
Kelly Jackson I'd keep that life all the same. I don't need to risk it with chemical exposure.
Andrew Halverson Yes, was understood. Opportunistic mild trolling w/tongue wedged firmly into cheek. : )
Andrew Halverson As a computer engineer myself, sometimes we also submit ourselves to great risks... Like when you are handling automation software in a factory.
But then again, not every computer engineer will have to go through that.
+Kelly Jackson Hackers? Whistleblowers?
During my Ph.D. research I prepared about 10 mL of dimethylmercury for use as an NMR standard. While transferring the product into a bottle I spilled some on the front edge of the fume hood withe a small amount flowing outside it. I remember the smell as being rather sweet and not unpleasant but fortunately it seems that my exposure was small and I'm here to write this.
Many comments here mention dimethylmercury, but at least you are one, who really work with it👍
That's truly terrifying stuff. Glad you made it out ok
When did that happen? I thought that with the unfortunate death of Karen Wetterhahn Me2Hg is recommanded *not* to use.
@@ShouldOfStudiedForTheTestHe didn't touch it directly, unlike Karen
That last one with the sulfuric acid is legitimately terrifying, what if he only had 1 pair of gloves at the time
He would never need gloves again
Just imagine if he had No gloves
He would now be called "stumpy".
Well the next person would know to wear three.
He would have been unhappy

I used to handle neurotoxins all the time, back when gasoline had Tetraethyl lead in it.
Wew I remember that. Lead in petrol. A neurotoxin but put into petrol to solve a mild hiccup in engine. Caused serious environment and social issue over decades. It show money trumph morality and ethical conduct.
There are actual graphs showing its invention and eventual ban correlating with a sharp increase in violence that then decreases when it was banned. Not that it was the cause, only it did look like it.
Ziquafty Nny Correlation != causation. But yeah I saw it on Vsauce vids. Still interesting perspective thou
I've been handling fuel with tetraethyl lead for the past two years haha
100GTAGUY RIP man
Hearing the third anecdote, I'm really amazed there aren't more accidents happening than what appears. It sounds as if what he was doing was routine procedure.
As soon as I saw his hair, I knew he knows Science
Haha, never understood the thinking behind ampoules. Designed to hold dangerous substances while requiring relatively rough handling of a brittle container to actually get the stuff out.
samthepoor Ampoules are NOT designed to hold dangerous chemicals. They have been around for centuries and are merely a way to hold a substance in a sealed glass container.
+Pelican1984 Indeed. They're a fantastic way to transport water-sensitive or air-sensitive compounds, as it ensures there is no seal that can possibly leak.
+samthepoor your local paramedic probably has some EFFECTIVE but harmless ones.
In my country its some sort of emergencymedic that does that stuff and the paramedics just help them out if they have to come.
they're not so bad when you've got that tool to snap the top off them, I think part of the reason they exist is coz the compound is very securely contained that way
What tool? I've never needed a tool to open an ampule - the top is usually just snapped off.
Chlorine trifluoride is pretty mean when things like "the concrete was on fire" are phrases often uttered about it.
Yes, hexafluorosilicic acid is commonly used in water fluoridation. It will react with concrete if you concentrate it enough, or if you wait long enough.
For reference, hexafluorosilicic acid is approximately half as toxic as caffeine - LD50 of 430 mg/kg vs 150-200 mg/kg.
ThinkingSpeck lol guess that's why they told us to only drink a max of 4 jolt colas in a day but to drink at least 8 glasses of water a day. here is some poison... oh wait that's to much. now it's just right lol
Chlorine trifluride also called "Substanz N" is really nasty even Nazis was it too dangerous for use in weapons
Also "known to be hypergolic with test engineers" really, I did NOT make that up, I am a test engineer so it caught my eye.
ThinkingSpeck Are you in any way related to a certain USAF general?
"it explodes on contact with the atmosphere"
Pure sodium explodes if you put it in water
3rd guy : almost died to a cloud of sulfuric acid, that was fun xD
I handled marijuana one time. I almost died 6 times
Marijuana has never directly killed anybody... Nor has anybody ODed.
+Draevon May That one flew directly over your head didn't it?
+Draevon May You must be fun at parties huh?
+leon bushnell
It is physically impossible to OD on marijuana. What you are arguing for is an anecdotal fallacy. The science says it's impossible. Cannabinoid Receptors aren't linked to your lungs.
People have had acute cannabinoid psychosis and stuff of that nature, and some people have a predisposition to rejecting marijuana, but it is impossible to OD in the medical sense. In the colloquial sense of "oh I had too much and I didn't feel great," yes you can "OD" but that isn't a true, medical, OD.
+Draevon May Please.... What Ashton said is a joke used to criticise the idiots that think Marijuana is some kind of dangerous harddrug. Get it? It's irony, sarcasm, not serious.
So you wore 3 sets of gloves, had the fume hood going, etc. How about a dehumidifier?
***** meth lab is the first thing came to mind
+michaelrose93 I was thinking: aren't you glad you didn't say, "Meh... two of these gloves should be enough...."
Pretty sure a dehumidifier would break.
Peter Osther Point would be to remove the water before the SO3 can get to it. Chilling the fumehood to -20°C or similar would have a similar effect with less expensive equipment destroyed.
John Francis Doe Yeah but try chilling a lab easily to -20 degrees
I've never had experience with it, but I would say organic mercury is the scariest laboratory chemical I've ever read about. A drop or two on the skin can cause a slow, miserable death.
I was looking for this comment. I had pretty much the same thought.
Organomercury compounds*
The nasty thing is it will penetrate nitryl gloves as well.
they used mercury as medicine back in the years. so people ingested it (and didn't die of course)
I encountered a very toxic gas one time when I decided to go and open the restroom door after my Grandpa used it it literally almost burnt my lungs 6 people ended up going to the hospital that night
After he had taco bell
this shouldn't have made me laugh as much as it did
Someone probably mixed bleach and ammonia.
wait you have to break it with a hammer? I was under the impression that you score the neck and kinda pop it off
Idk man.... Maybe it was a long time ago
+hornylink I never bothered to score them. Have opened thousands without a single incident.
Kinda like the liquid stink bombs
hornylink No one breaks an ampoule with a hammer! What that guy was thinking, LOL!
maybe you cant remove the top with 3 pairs of gloves on like normal?
Sulfur trioxide seems almost as bad as windows 8
I think its windows 8 is worse i just got a pc and it had windows 8 so i returned it...

"I had a 250 ml bottle of SO3."
Oh dear.
In the course of my laboratory career, I've handled the various bacteria that cause anthrax, botulism, tuberculosis, and leprosy. Also loads of other bacteria, fungi, viruses, and parasites that cause other diseases, though most of them don't require extraordinary handling.
So, do you want a medal or a chest to pin it on? Nobody is talking about bacteria, they're talking about chemicals.
Clostridium botulinum is the bacteria that produces the toxin that causes botulism. It produces some of the most deadly toxins known to man. No need to be petty just because you don't understand, Jim.
I think Roger does deserve a medal. I'm a microbiology student and if I'm risking my life to try and save yours, I want the damn medal too...just kidding. Sounds interesting though, can't wait. All we get is staph and e.coli to play with
I mean, to be fair, most if not everything is a chemical. Bacteria from what I know is made up of complex chemicals, so he's still talking about chemicals either way no matter what he's handled.
Did you ever drop them on the floor or melt your gloves with them?
"Most dangerous chemical in the world" and the old man drops it :/facepalm:/
tmac20031 He lives life on the edge bro. He may look old & boring, but secretly he's full of adventure.
ImJustACowLol Adventure begins usually with an appointment with his hairdresser Raoul. . .
tmac20031 Still not as dangerous as azidoazide azide, dioxygen difluroide or fluoroantimonic acid, but still pretty damn dangerous.

I am addicted to this channel. Chemistry is amazing! I've learned so much about different metals.
I've burned a wotsit in a bunsen burner to test how much energy it has, almost died, I can relate to these 3.
What is a wotsit? Wotsit do? *badum tush*
I'd prefer deal with dangerous chemicals than dealing with dangerous bacteria/virus :S
i totally agree. if a bacterium/virus gets out then it starts multiplying, thats real bad and everyone dies. but if a chemical gets out, it wont multiply
Coff coff BX coff coff self replicate proteins coff coff a lot more
But actually, you are right
@Statiscube yeah "sure"
Hey 2021 here. We all agree with you
I prefer working with dangerous chemicals and biohazards than politicians and lawyers !
I remember when I was an apprentice, I thought the membrane (the thing you put the syringe into) on the t-BuLi bottle was under the cap. I opened it and could look straight into the liquid and knew that couldn't be right. I was mocked for a few days (in a friendly kind of way) and then my instructor dropped a bottle from the bench onto the floor but thanksfully it didn't crack.
As a person who is in their 6th year of high school (12th grade for Americans, year 13 for English people, being Scottish myself) for my Advanced Higher Chemistry we had to do an investigation, of our own choosing , I ended up doing stuff with reductions of sugars using Benedict's reagent, which is all fair and well. The problem was when I tried to titrate it with simple cola, which because of the acid in it formed a little more Hydrogen Cyanide than I would have hoped for, which was a, I'll say, nice surprise.
no H20 ? that thing is scary..
It really is if you have SO3 around ^^
But it is much less dangerous if you have twice the amount of KOH ^^ because H2SO4+2KOH ==> 2H2O+S+K, or rather 2 volumes of water, plus one volume of sulfur and potassium each produced by 1 volume of Sulfuric Acid and 2 volumes of potassium hydroxide.
yiu yeung Kan While that might be true (I didn´t check in detail) you dont want clouds of KOH floating around in your fume hood. ^^
Are you made of sodium ?
Uveitis?
These videos of Real Scientists dealing with Real chemicals and reactions is absolutely amazingly fascinating. Great material
i want someone who respect me as much as this guy respect Tertiary Butyllithium molecule
HAHAHAHHA
@@abdullahshahidsial7676 hakdog
Dude that last one though, heck no I quit.
This guy looks like science.
The most elaborate precautions I had to take were when handling tritiated water. Tritium is kinda insidious : it's a low-energy beta-emitter, but the beta particles it gives off have such low energy that they cannot penetrate the mica end-window of a Geiger-Müller tube. So detecting it is hard. But tritiated water is doubly insidious, because, in the same way that water exchanges hydrogens between water molecules all the time, so too will tritium atoms swap with hydrogen in water. And, in the UK, there's always plenty of water in the air. And the largest body of water in almost any lab is the body of the researcher....
Fortunately, tritium in the form of tritiated water passes from the body quite rapidly, with nearly all of it being excreted within 48 hours.
Just imagine someone following you with a siringue and instead of injecting you from behind he just throw fire with it straight to your face.
"Ha ha ha! I nearly died."
“The most dangerous chemical I handled was Hairspray & electric socket.”
Dude how r u still alive 😱☠️
Much respect to the people who take their passion so seriously. Thank goodness these are mostly kept from the ones who could do some serious destruction.
My grandfather who worked at British Drughouses (later became Merck), was given 3 months pay to pour a chemical from one test tube to another. They wouldn’t tell him what was in it. They watched through binoculars from 1/4 mile away. That man went on to develop Complan.
mine was finding a bottle containing 90% VX
that shit was scary
"...with a _hammer_..."?!?!?!?!
Seriously!?!?!
A HAMMER?!!?!?
WTF?!
No, a hammer is completely inappropriate. You use a file and slightly etch the neck, then the top will pop off with finger pressure. No idea what this guy is thinking of. Vials have been used in medicine as well for a couple centuries, and I assure you doctors do not use hammers to open them.
I think maybe the file would have been far too slow for something that is reacting so violently with the air, thus the hammer. Maybe they could have found a way to file it loose in a vacuum instead? But maybe they didn't have a way to do that.
itchykami Obviously you have never used any form of vials. Thin vials can be snapped open with just your fingers. Thicker ones are merely scratched with a triangular file to create a stress point, then broken open with your fingers.
You're right, it is obviously more likely that this professional scientist doesn't know what he's doing, and you do. I bow to your limitless wisdom.
itchykami have you ever opened one? You would never use a hammer.... that's completely ridiculous
Most dangerous Ive handled was a bottle of liquid mercury. I work at a sign place, and mercury was used for the neon when that was still popular. I couldnt believe how much weight there was to the small bottle it came in
@ 1:53 - That looks exactly like the prank fart-bombs i bought at the fair when i was a kid. They came in the same glass casing, and you had to smash them on the ground to release the odor. 😂
In terms of fatalities it must be water.
Chronic oxygen poisoning will finish you off if nothing else does.
DNA is pretty bad. Practically sentient and extremely hostile.
Dimethylmercury is one of (if not THE) strongest Neurotoxins known to man.
Oh no. I remember breaking an ampoule stink bomb in the mall with my friend when I was 13. I never knew what those bottles were called until this video. It stunk up the entire mall. I feel bad now.
Just commenting in 2021 to boost the algorithm. One of PV’s best videos ever! 😂
I was kinda disappointed they just said the names of the substances and didn't really talk much about what these nasty chemicals could do to you. Only the last person, who discussed SO3, talked about that.
The second one showed a literal flamethrower on camera
what do you think poison and fire do to a person.
1:57 um, no you just snap it off the neck is usually pre scored and all you have to do is take a paper towel wrap it inside and snap the top off. Then to seal it back up there are allot of ways to do so but I prefer to use parafilm, yes I break these things open quite often as they contain the QC and even some testing reagents within.
I would think that the best way to handle air-sensitive chemicals would be an isolation box full of noble gasses, but I'm not a chemist.
When I worked at an electro plating plant, I used to handle hydrofluoric acid on a regular basis. We had to empty and refill a small-ish acid bath on an aluminium plating line. This involved stopping all the other staff from working, they would go out of the electro plating shop area and wait in the canteen vending area. Then two of us would put on positive air pressure facemasks, full length rubber aprons and elbow length rubber gloves, over our wellington boots and acid resistant overalls, legs NOT tucked inside the boots. Then we would pump out the acid bath into special containers, flush the bath out with many gallons of water. Dry the bath completely, add various acids, including Hf, to the clean bath. The HF "smokes" when it contacts air and other chemicals!!
good fun!
I'm amazed nobody gave a shout out to dimethylmercury, that stuff is pure nastiness...
You are right, even with glooves you are not safe
The key is “that you have handled”. Nobody handles that stuff anymore since the days when someone died from a single drop over a glove, because there’s no use for it anyways.
Shout out to dimethyl cadmium as well
@@eier3252 I came here looking for dymethylcadmium. 1 millionth of a gram and your toast.
@@cheesestyx945 Generally heavy metals bonded to organic stuff is bad news
Love these guys and the passion they have for science. It made me smile a bit though the way they have a bit of boast in the tone of their voice as to what was the nastiest stuff they had ever handled lol. Bit like the Monty Python Yorkshireman sketch
I think the concept of "dangerous" is interesting. I was trying to define it before the video started, by working out properties.
Very unstable (like nitroglycerin), so handling it is hard, then I'd go oxidizing/explosive so that there is less chance you can drop-and-run if it looks critical
"Cyclopentadienyl nickel nitrosyl" The name in of itself is a monster !
No dihydrogen monoxide on this list?
+Ran Kavik No, dihydrogen monoxide CAN be dangerous, but generally is not. The chemicals on this list wake up in the morning thinking of ways to be even more dangerous than they were yesterday.
+Ran Kavik Actually water tends to behave as the molecule Hydrogen Hydroxide in most situations, or so I've heard
+jmowreader Haven't you heard that every person who has ever been in contact with Dihydrogen Monoxide has died afterwards, or will die afterwards? It's not something to trifle with!
Dihydrogen monoxide AKA water
Party breaker :(
My grandad used to tell stories of handling zyklon-B with great caution.
The third guy and I have very very different definitions of "fun".
Let's not forget about fluoroantimonic acid
That's very nasty....but....it will only burn your skin. How about monofluoroacetic acid? Go check it out!
Clyde Wary And your bones. It can only be contained in teflon containers... Nasty business.
Sean71596 Or chlorine trifluoride.
Sean71596 Fluorine compounds have long been used as SiO2 etchants. Having been in a semi-conductor group about 30yrs ago, they were avid to get hold of an ointment/cream/? that would quench such an etchant's attack on skin --- applied immediately it could keep the acid from reaching bone.

What about fluoroantimonic acid? Most acidic substance known to mankind. Capable of protonating even carbocation containing substances. pKa of -25. 10^16 times stronger than pure sulfuric acid.

Fascinating
0:13 Hello! I'm (C3H3)NiNo!
Depending on your definition of dangerous, dimethylMercury / organic Mercury is very toxic and requires extreme handling protocols.
I know this is 2 years old, but I mentioned that as well.
I'm now curious about what possible definition of "dangerous" would exclude (di)methylmercury.
Glad to know the potential risks of chemicals that I have never heard of
For anyone curious, ripped from wiki
Cyclopentadienyl nickel nitrosyl
It was patented as a fuel additive and anti-caking agent. It was also studied for its spectroscopic qualities, and saw limited use as a catalyst in organic chemical reactions, but it has since been discounted in favor of less toxic compounds.
tert-Butyllithium
As an organolithium compound, it has applications in organic synthesis since it is a strong base, capable of deprotonating many carbon molecules, including benzene.
Sulfur trioxide
It has been described as "unquestionably the most important economically" sulfur oxide. It is prepared on an industrial scale as a precursor to sulfuric acid.
"and I dropped the bottle on the floor and it broke"
Highly unlikely.
a hunk of potassium.
i threw it into my teacher's cup of water.
+clive tan how many limbs did you lose?
none but the cup, and table was gone (was made of cheap plastic)
*****
clive tan Consider yourself lucky, must have only been a tiny piece of potassium since that stuff is VERY reactive
@TheDerpy Kitty about like the cup and table did im sure...
How abaut Sarin, Tabun, Soman and VX nerve agents, chloren and mustard gas , Fluoroantimonic acid, also white phosphorus and the fumes it creates when it spontaneously combusts
some Uranium compounds are pretty reactive towards oxidation - thereby you can get radioactive burning metall , releasing evaporated radioactive metall pretty rad even with fume hood
ultrasensitive primary explosives like manganese heptoxide maybe
I started a fire by accident in high school chemistry, but the other experiment ran simultaneously and interfered. It being my first experiment with both LSD , and whatever it was we were doing in class..

0:10 . . Sounds by name almost like some of those alcohol concoctions we used to drink at student parties in our freshers days. . . Ah the sweet memories
Why wasn't the lab working area de-humidified before decanting the SO3 from it's ampoule ?
While they were at it they should have just made the sulfuric acid non-corrosive... Oh wait, that's essentially impossible, just like a 0% humidity room filled air and with exhaling meat sacks that are made of 60% water.
for me it would be DiHydrogen monoxide
bruh
Yeah
@airdaddy
I wondered where that smell was coming from; French by any chance?
I only mention it because I've known several, all with a rural upbringing, each of whom also share an aversion to that particular compound.
Terrifying.
iam immune to it now and can drink it without any harm, , your body adapts quickly, try it.
Always wondered how these chemicals are made and packaged safely by the manufacturer but so dangerous and reactive to " play with"
