Chemical Weapons (Sarin Gas) - Periodic Table of Videos 

Even as a kid, the Professor was already a chemist.

I would love to see an episode about protective suits and the special lab equipment and techniques used to protect yourself. I know you love safety Professor, and I'm sure Neil wouldn't mind wearing the suit.

I've got a molecule of sarin here Not real sarin? NO I HAVE ONE SINGLE MOLECULE OF GAS HERE WOULD YOU LIKE TO SEE?

"Just let me warm up the neurotoxins." -GLaDOS

That tie is brilliant.

I love how Rob clearly explains how molecules work.

We are all now on the NSA list, thanks youtube

harmless professor in gas mask = stuff of nightmares

I really love that old guy, I could probably listen to him for days.

The first thing that came to mind right before I clicked this video was “this is how you end up on more watchlists”

Prof. Rob has the most soothing pleasant voice to listen to.

I wish I had you guys for science classes. I've learned more your videos, than I did in class😂😅

As a chemist, I found this extremely interesting. Thank you for making this video, guys!

When will I be able to have ATP shakes and replace food altogether?

I met him when I attended one of the University open days, he's as humble as he seems in the videos!

Now I am really afraid of chemical warfare... Sarin is scary!!

Speaking about the gas mask I once did a university placement studying Radon; and again it was found that activated charcoal made from coconut shell is the most efficient absorbent. Even more so when cooled by liquid nitrogen. A cryogenically cooled-gas-mask may function even more effectively than a standard one. Interesting stuff.

***** I know this is a bit of an old video to be commenting on. But this was a great visual for me. We learned a lot of this chemistry during one of my paramedic classes. Mark I and Mark II kits used for field treatment of nerve agents, or organophosphate poisoning also included Atropine. We no longer carry Pralidoxime and our protocols change to an Atropine only treatment. Could you explain the chemistry behind how Atropine alone works to counteract nerve agents or how the combination of the two work together. I'd also love to see more videos about the chemistry behind more of the medications I use in the field. The way you format videos gives a visual and I feel helps immensely.

Thanks to these videos I actually have a better visual understanding of how molecules interact and react with eachother. That was enlightening

This is by far the coolest Periodic Videos I've ever seen.

this video was so fancy, lovely work and lovely chemistry!

I once heard that the antidote for a nerve agent ( I can't recall if it was sarin or VX ) was lethal if the user had not actually been exposed. Is this true? I started wondering about this when the explanation for the chemical interaction of the sarin antidote was given.

This is one of your best, Brady and Bunch!

one of the best episodes I've seen. Thank you !

It's hard to hear what he says cuz his hair is too mesmerizing

Very interesting video. I've been wondering how Sarin affects the body/nervous system since I read about the Aum attacks in Tokyo in 94/95. Thanks :)

this is the best video i've watch for a long time on RU-vid. Probably since the enigma-encoder one!

thank you for keeping this channel going, so much useful science on this channel :)

One dude giving us a molecular class...the other guy is messing around with a very old gas mask. And the cuts between each of them are hysterical.

Brilliant video - thank you for a level-headed, riveting, and sobering discussion.

one of the best videos of you guys. I would appreciate more videos about organic chemistry!

Thank You for your videos. I am very fortunate to have found your channel!

To my knowlege, the first time that poison gas was used in warfare, was in the U.S. Civil War. The gas was phosgene. I read about this in the book, "Chemical Process Industries," published by McGraw-Hill in the 60s.

“The thing that you breathe through”

BEST VIDEO YET - it is pertinent, historical, chemical and well-made. good job.

This was a really interesting video, with a great explanation. Thanks Brady and everyone else involved :)

These videos are improving my background chemistry no end. You guys make it interesting and easier to remember! Love them! From an environmental scientist :)

I came to be scared and fascinated, but as usual was simply charmed by the little child hiding in the Professor.

Informative and thoughtfully done. Great educational video.

Fantastic video ~ Filled with knowledge & insight as always + A great message :D thank you

"Esquire;" lol... so British

Switching between the prof's gas mask and neurotransmitter explanation a bit too frequently.

I love periodic table videos you always teach me amazing things, thank you so much for all that hard work! I'm a big fan. Greetings from Colombia.

Thanks for the informative video Brady and also to Professor Poliakoff and Stockman for the information! Haven't seen a gas mask like that in years but I'll bet it wouldn't have been nice having to wear one for a while, especially in a blackout.

12:30 Indeed, considering that you combat troops ARE equipped and protected I would say that it is civilians, rather than solders, who are the INTENDED targets of chemical weapons. This is most likely why they were not used in WWII and their use, even in modern warfare is so limited. Now I can see the use of such weapons as a detraction, if the enemy troops are busy caring for civilian casualties they can't attack you. I think it's clear they are meany to harm civilians more than troops.

This video predicted spidget finners

Very interesting! Thank you once again periodicvideos for such a good and informative video. Really like this channel and therefor I've been subbed for a long time :)

Good to see Rob Stockman back on our screens.

Are you my mummy?

This is suddenly very relevant!

That chemical detector isn’t so far removed from the kit I learned in the military, late 90s early 2000s, called they RVD (residual vapour detector) great vid 👍🏻

dude this is the perfect place for ALL discussions, including and especially politics. its certainly the right time as well.

That gas mask has to be worth some cash money

"Are you my mummy :c"

Desert Shield we were instructed in the use of Atropine and 2 PAM Chloride.

these videos are so interesting, thank you..I feel bad I messed up school so much

THEY PREDICTED FIDGET SPINNERS

We want you to know the chemistry so you can make it yourself... I mean... that it's bad. yah. XD

The cuts are brilliant

Subscribing you to you was a great idea. I feel like I can become smarter and work toward making a difference with my major.

5:47 "Are you my mummy?"

All modern warfare is horrendous. Say what you want about Saddam Husseins evil in Iraq, but in the course of the most recent Iraq war, about a quarter of a million people died, and the few of them were soldiers, and that was a war waged by one of the most advanced militaries of the world, the US. There's one United Nations institution we are desperately lacking, and that is one that specializes in counselling warring parties to tame the effects of armed conflicts, and providing publicly accessible military research for how to avoid civilian deaths in military confrontations. We need a United Nations Institute for Civilian Safety.

Very educational and topical. Nice job!

The best channel on RU-vid.

You are now breathing and blinking your eyes manually.

Alright if nobody else is gonna say it I guess that means I'll have to The thumbnail kinda looks like a fidget spinner

So informative and I really liked the editing too

Very well explained. Sarin stops the body’s on/switch leaving it on thus stopping breathing.

2:00 No, that is simply wrong. There was rampant chemical weapon use in Asia, most notably in China, by the Japanese. That fact that nobody, at least as far as I can tell in the comments section, has brought it up in seven years is kind of scary from an educational perspective.

It just got used to harm civilians in Syria. :(

How in the world could evolution make such a complex system, even if it took billions of years. It's unfathomable the amount of complexity that goes into the simplest action of a human body. Not to mention every single animal and omant. I'm in awe.

Great video! Please do one on VX gas.

Still not as bad as the most indiscriminate mass weapon of all; the atomic bomb.

I live in Utah and the Dugway Proving grounds where much of this stuff is stored is less that 200 kilometers away. Much or most of this stuff has been destriyed at Dugway.

Thank you for teaching me! Namaste I know you have worked very hard for the knowledge and wisdom you contain

What a coincidence...I talked about this on my first day of class (today) with my first year chem students. I made up a Powerpoint last week and I also used Pacman for a sarin representation! I thought it was a really clever idea...guess I wasn't the only one! :)

Been waiting for this video :) thank you

That last bit at the end was sooo comforting :P

This has been a really interesting episode.

Man this video has made all the crazies come out the woodwork...

I love it when I already know some of the content of these videos :D

It works in the same process, it is just better at it. I can't specifically say what is better about it or how it does it better, as I am not as good at chemistry as the creators of this video, but it does work in the same way.

sarin is an organophosohate, VX works in a very similar way with different sidegroups on the phosphate. the distinction in G and V-series is mainly historic aside from Vagents being more potent by weight and more persistent after release

It depends on the dosage of the gas, in a confined space nerve agents can kill within minutes if that, however you're correct that getting a small lethal dose in a ventilated area would lead to a very long drawn out death which I assume would be agonizing Nerve gas really is a terror weapon much like nuclear weapons and biological weapons, it's more effective against civilians than soldiers and works best in concentrated urban areas.

Great now we would be most obliged if you did a video on VX organophosphate nerve gases

Great job editing.

Really interesting video! Now I have a doubt. A person with myasthenia gravis would have more tolerance to the gas? The excess of acethilcolinesterase is the main cause of their symptoms.

GREAT VIDEO.

Great video and nice quality. Got a new camera or lens?

Nice tie doc! What do you think of the new proposition for the mendeljev table? The one that presents itself as a spiral.

“Now that’s vinegar now” I liked that illustration. So many Americans don’t understand the way that chemistry actually changes the identity of substances, they mistake it for something like a cake recipe where the inputs remain. Though in the animation not sure why they didn’t just depict the sarin molecule as a Pie wedge filling acetylcholine pac-man’s mouth.

Would really like to see a series just on the nervous system. Had no idea there was more than electrical signals going on. Very interesting!

Awesome 👏 Well explained! Thank you 😊

Amazing channel!

Amazing editing

Great explanation.

Coconut shells/Charcoal is still used as a filtration agent in Diving/breathing air compressors

Thank you for this video!

Very well explained

Where did the outtakes go? I can't believe it's taken me this long to come across these videos - fasc-in-a-ting!
