You the most ironic thing was: he himself, wasn't wearing a labcoat
I'm sure he's done this procedure many times and knows the chemical reactions.
+mossy1s Nah i doubt it he looks like a rookie
all that youth in his face
@@mossy1s Go poll people who have spilled chemicals on themselves or been burned and ask them how many times they had done the task before. Industrially PPE related incidents where someone wasn't wearing the appropriate attire because they had run the process incident free for whatever interval of time are insanely high.
I like the attitude of keeping safety serious even if it's not that big of a deal. Act as if it's a big deal anyways to make it a good habit.
Same here because u never know what's going to happen. Better safe than sorry.
Less talking, More dropping.
But yet he wasn't wearing his lab apron..

This man has such an aura of bravery that it forms a protective barrier of testosterone around him. Any acid that makes contact becomes a fine pilsner beer.
+Yee Macghyee HAHA! This comment just made my day
lol
That's how Heisenberg started... He looks like him too
It's ironic that he isn't wearing a lab coat.
THANK YOU XD
Haha very very ironic :)
Yep, I thought the same thing. And his right hand is not gloved. Do as I say, not as I do I suppose.
If wearing lab clothing is so important, why is he only wearing one glove and some goggles, where's the lab coat!?
Watch it again, Along with the 18 people that thumbed you up.
31*
@@TheProCactus ok????? i still don't see the lab coat, the guy is wearing one glove, and the guy is only wearing goggles. you need to wear all three
"Kids are dumb so we have to show them what burning looks like."
Who's here because of Dr. Stone?
o/
Definitely me 🤣🤣🤣
😂😂😂😂 no way me too this is hilarious 😂
ME LOL
YOu get me.
Yo mr.White
yeah mr white yeah science!
Very nice... no gloves on the right hand and no lab coat!
Ooh look!
3.5837
Many numbers is equal much very science wow!
I wish i went to school in america...
Schools in norway never teach us about chemicals and how they work because of the laws and regulations...
sadly its getting that way too in america =( i got to use hydrochloric acid though =D
@@elipurser6893 bruh my school lets me play with sulfuric acid, blowtorches, pure potasssium metal what you on about?
you are good at this. people are saying you are not being safe but you are being safe when you are doing that.
He breaths very loudly
"Yet another reason to wear my lab apron."
Wears one glove, improper air filtration goggles, and no apron.
If you get 18M sulfuric acid on your skin, DO NOT WASH IT OFF WITH WATER. The water will boil on contact with the acid! Just drop a little 18M acid in a beaker of water, and you'll see what I mean. Neutralize the acid with a weak base, like sodium hydrogen carbonate. The same applies to strong alkali, like sodium hydroxide, which can be neutralized with dilute acetic acid (vinegar).
ok
i need a teacher like him
Did the channel name FlinnScientific not give you a tip it is SCIENTIFIC!
Awesome!!!
"Students don't know the difference between 12 molar sulfuric acid and .001 molar sulfuric acid" excuse me, students are not idiots.
+Iris Sanderson When were you in school? In my experience they were in fact idiots and appear to be even more so today.
Nevir202 I am currently an AP student, and I can honestly say that the dumbest people I have encountered at school could demonstrate safety better than this guy.
If he’s going to mock students for not understanding how dangerous this acid is, he could at least bother to demonstrate proper use of safety equipment (no apron, messing around without having done them previously 2:28)
If you’re going to mock students for being dumb, I’d like you to keep in mind that the point of being a student is to learn. If you’re going to insist that students today are dumber than the students of past generations, I’m reminding you that as generations pass, scientific knowledge increases, and therefore the amount of information available to this generation greatly surpasses the information available to previous ones. Todays students will grow up with the most recent and more reliable knowledge, and if you have a problem with that I’ll kindly ask you to fuck off
Iris Sanderson
Knowledge =/= common sense nor does the knowledge of the whole of humanity directly translate to the knowledge of any given individuals. So your argument pretty flawed on both fronts.
+Iris Sanderson 94% of them are.
+Deca Hedron You've never been in an above highschool level lab have you?
That's very cool! I want one to clean the drain in the pipes! :D
Where his labcoat/apron????
I like this guy !
Where is Jill Sheridan now? I remember her tights dissolving in science class back in ooh maybe 1974 or so!
Chemistry really ruined the mystery and my appreciation for acid.
why
MrTNT6000 because reality hit him
whoa tats scientific! but seriously some of us are quite inteligent
Masahiro Wakahaya got emmmmm
Masahiro Wakahaya Haha!!
Masahiro Wakahaya Perhaps he isn't a native english speaker? And spelling doesn't suggest one's intelligence.

No i can not iushgiuyhweiuregh
Nice channel
I will be doing a small chemical experiment in a university lab with
high concentration CHlorosulphonic Acid. Does it need extra precaution ?
any recommendations ?
Thanks for aceton thing.
And he says and does this ..wait for it.. *in a T-shirt*
ba dum tsss!! xD
Charles Martinet melts your face off.
4:39 nice air raid siren in the background
what was the 2nd acid that he used called?
5:30 scary image of a ghost dissolving
the videos starts at 2:30
thanks !
THANK YOU!
Good video, well illustrated. Didn't like how he made out that kids/students are stupid.
Well,they kind of are stupid.Until you feel the burn you don't really know what you are dealing with.So yeah.
doarmemo18 Act like everything is super dangerous when handling chemicals, its a habit I've made and it helps.
I've gotten conc. H2SO4 on my hands many times. It doesn't do anything if you wash it off fairly quickly. And in all the chemistry lab classes I've taken, nobody ever wore gloves. Of course, eye protection was always required.
Clyde Wary You never got 18M sulfuric acid on your skin. A few seconds is all it needs to leave a nasty burn.
i like how he puts a plastic dropper in acid
what kind of plastic the bottle made from that it doesnt react with sulfuric acid?
2:26 that voice crack tho
I love that guy :) im dissolving hah aha
Wow
Alright, who’s the genius that decided to record on siren test day? Starting at 4:40, they’re audible
i think that sounds more like a high voltage electric device doing its thing, rather than a siren
Jajaja interesante y el es divertido
Does video about the safety of wearing a lab coat when working with acid, doesn't wear lab coat while working with acid.
WOW
how i can check if there is Methanol in alcoholic (Ethanol) beverage ???
Robbin Williams, is that you!?
Talks about lab safety, doesn't wear adequate protective gear himself. Not even gloves on both hands...
Highly concentrated H2SO4 won't break amide bonds in nylon, the polymerization degree of Nylon is determined via viscosimetry in conc sulfuric acid
"All nylons are susceptible to hydrolysis, especially by strong acids" en.wikipedia.org/wiki/Nylon#Hydrolysis_and_degradation if the amide bonds arent being broken, what then is occuring?
The water activity in concentrated sulfuric acid is basically 0, so there's no water available for hydrolysis (the mentioned lead battery acid is just ~30%w/w which could lead to hydrolysis). The nylon just dissolves, probably because the amide groups are protonated exploding the weak bonds between the polymer chains.
And again, how could the polymerization degree be measured in sulfuric acid when it depolymerizes? vtechworks.lib.vt.edu/bitstream/handle/10919/46806/1.549633.pdf?sequence=1
So the sulfuric acid disrupts the polymer-polymer bonding (H bonding, etc) but not the actual polymers amide bond as in hydrolysis. Good to know ty.
Sadler A No problem, I learnt that the amide chains are highly protonated in sulfuric acid and formic acid...the more you know...
He reminds me of Bubbles from Trailer Park Boys haha
If your students dont know what it means u havent done your job!
Well, I've thought about it, and I have to elaborate about how I feel about the humor here.
With all due respect to the instructor, perhaps it's just me, but I find the humor here to be in poor taste because women, no matter what religion, are the beauty of the earth and have suffered a great deal on this planet. As a child, when I watched the scene in the Wizard Of Oz movie where the witch was melting, everyone around me was laughing, yet I cried. I can't completely understand it myself, but even in a fictional situation, it hurts me to think about any human being being hurt or tormented. But, I guess that's just me huh?
Tim Rubin Halcomb I think you misunderstand the intended purpose of humor...
Perhaps. Sorry.
Tim Rubin Halcomb
You should read the Wicked series.
Krystal Matthews
Thank you and I will.
Tim Rubin Halcomb Nothing to be sorry about, just keep trying to understand the intent.
superglue has a similarly dramatic effect on styrofoam
Glenn, are you?
The additional layer gives you a bit more time to get off of you before burning through.
starts at 5:16...
Nyx Assassin 2:16 u mean
Foamy Koolguy no. its 5:16
Nyx Assassin are you even listening to the video and reading its title? the title says sulfuric acid and nylon, this is what happens at 2:16. at 5:16 it´s acetone and styrofoam
No, I'm sure the video starts at 0:00
+Generationplay i think thin nylon socks didnt satisfy him :D nor the 1.0*10³ Ka number :D
Acetone has too
Help Me I'm dissolving! XD
sulphuric acid dissolves rubber gloves and nitrile ones or which are safe?
Sulphuric is safer than nitrile
9 N why? :)
5:32 you're welcome
That's acetone (nail polish remover), not sulfuric acid.
that's not the point
He's a fucking PRO, he doesn't need an apron xD
what happens to humans when they pour this on us from the sky?
why do I get the feeling he has the same set up in his basement?
so why did it not melt your gloves? latex right?
It does
Someone here bcs of Dr.Stone? :D
SAIMATA NOoo!!!!!!!!!!
rip
+lolb4udie lol fail
(talk, talk,talk) HIHG (talk,talk,talk) HIHG (more talk) HIHG
nylon
something that reminded me about vocaloid tale Xd
Just wondering what do we do when you get concentrated sulfuric acid on your hands? As we are dealing with it in the school lab now, teachers only tell us to be careful but never told us what to do if it happens. We do not get gloves or what ever so i'm always very nervous when i am transferring it into a test tube.
it can burn through your skin flow though your body and at some point kill you it is a painful way to die
+natasha Just pour some concentrated sodium hydroxide on it. That'll neutralize it.
But seriously, lots and lots of water.
but neutralisation is exothermic right? won't it burn me?
+natasha Yes, I was joking. The sodium hydroxide can also cause chemical burns and pull the oil from your skin in that area. Just run a lot water on the exposed area immediately. Also, wear goggles.
jarryda oh...haha lol did not see that. oh okok, will there be permanent damage if i wash it immediately?
word has it he later stepped out for a smoke and told some students there it was bad for their health
Two
Says students are stupid. Doesn't wear lab coat. OKAY.
Yes, i'm surprised his head didn't explode.
close your eyes and imagine it's Walter White from Breaking Bad speaking. So close!
i love watching videos filmed with a walnut
+PerpetuallyPissed
Well, it beats a 144p potato phone.
What seems to be suggesting that delivered the nylons on a woman's head? It is a drastic science.
I hear tornado sirens in the background.
Obviously not nylon or polystyrene lol. LDPE is pretty common in lab plasticware.
No no guys, he said the students. The students should wear 'em.
i will put it on all bank robbers
can it even get at 18 molar? i tough it was like 12.5
aajjeee That's HCl+
yeah i missed the part where he said ''sulfuric''
But, after all, they're asking what happens when you spill sulfuric acid on your clothes.
Therefore, hopefully he's not wearing nylon.
This stuff gives me the creeps its truly terrifying.
That looks like it won't tickle
that is the creepiest looking nylon tights on a model head I've ever seen
I think you could watch the whole video and pay attention to what is said on it...
I like him too. =)
video starts at 2:12
I think you could read the title of the video...
but acetone doesn't do that to skin
I find it a bit ironic that he wasn't wearing an apron, or a lab coat. The one glove on was a nice touch.
I like how he's supposed to be professional, and when he poured out the acid it rand down the bottle's side, and right afterwards he touched the bottle with his bare right hand..
+VikingFevahGames Luckily it was only acetone, the main ingredient in nail polish remover. I used to play with that and Styrofoam all the time when I was ~9.
Matthew Traver ahh, okay. I don't know much about chemistry, I just assumed it was a bottle full of sulphuric acid.
Nah, that was just the dropper and the small bottle. the big one is the acetone.
This is the most ragtag demonstration I've ever seen 😂
Sulphuric acid dissolves all clothes but polyester, formic acid dissolves nylon but not cotten, dimethylformamide dissolves acetate and elastane but not nylon or cotton, medium strength sodium hypochlorite dissolves wool and nothing else, hydrofloric acid dissolves everything but leather
A little bit fell on my hand and im fine
2:11 That's what you came here for.
Took 2 hour for the sulfuric sludge to dissolve a chicken wing when i did this in school
im here because of pumpkin night haha
#no lab coat
