awesome! What simulator did you use? Can we simulate all other interactions visually like this?
Awesome video. I teach college biochemistry and work in a molecular graphics laboratory, and I learned stuff - so that's a thumbs up from me. I do agree that the title is misleading - perhaps it should be called a "virtual microscope". And is it a computed quantum mechanics simulation? I discussed it with our QM expert here, Diogo Santos-Martins, and he thinks it might be, or at least is based on one. The movements of the particles looks realistic, at least, but it's a bit suspicious that they stay so planar. I wish there were a better explanation in the caption. Also, they said that the actual reaction was a bit more complicated - I'd like to see more about that. All in all, though, a great effort. I'd love to see more videos like this.
Pure hydrogen atom burn?
@fi s I also found the illustration helpful. It would be interesting to see how the reaction between the aluminum and sodium nitrate (drain cleaner) and water works to produce hydrogen.
Great job! Loved the simulation. Subbed and liked.
thank you for this sharing this info as i knew nothing of this, and the illustration made it easier to understand.
don't be so modest, you are so smart !
oh my god, pici_24 thank you !
you welcome pici_24 !!
sorry people, I've just discovered that youtube allows me to talk to myself !
I feel like home in here ! :)))
@pici24 thanks..:)
I found that quite interesting. So complicate to create a simple H2O molecule - who would have thought?
Excellent video, thank you much appreciated : )
This makes my chemistry class look more simple than it really is
Awesome. I know a bit of chem but this was fun to know some intermediate steps to the production of water.
Awsome video and the best explanation ever !
Thank you for sharing !!
Awesome job, Mel.
Thanks.

I was not aware that Oxygen atoms had an O stamped on them, and hydrogen atoms had an H stamped on them. Also, that's a very powerful microscope.🤔
This is a really good video! Great channel!
One of the few times I can easily forgive the quasi-clickbait title. This is an excellent visual presentation of a process that goes on all the time, and yet so few understand. Let's face reality, all you downthumbers: would you have clicked on this lucid and top-notch vid if it had had an unexciting title? The fact that you, and I, clicked is proof to the contrary.
Otherwise, though, I share your Sith-like hatred for clickbait that doesn't provide equal or greater value of that expected. Which is well over 95% of them. I'd say however that this one is in the "provides greater value than expected" category. As much as I like to see what we've imaged in the micro and macro world, it is even rarer to see a presentation like this that presents a chemistry topic in such an easy to grasp manner. Cheers.
i was searching for runaway polymerization and came across this video - outstanding graphics and narration
Wow this is really interesting thanks for uploading
thank you for sharing your work!
Nice! But given that the chain reaction is only possible in the presence of unstable (or "active") particles which rip apart other particles in turn, how is the experiment at the end successfully going through this process? Wouldn't one presume that everything was stable in the NaOH as well as in the aluminum foil prior to the interaction?
Amaravora Well there are atleast a mole of particles in those reactions. And on mole there are something like 6*10^23 particles. So there must be billions of trillions of radicals just nyt chance
Oh okay, I thought despite the large number that they would've all reached a stable state given how much time has elapsed (the elements are at least 4 billion years old, no?) :)
Nothing is 100% stable. Everything, especially large numbers of particles, are subject to random events, some of which result in prodution of free radicals. That is why you need for example antioxidants, because free oxygen atoms harm you body and antioxidants prevent that.
ohh, so cool! Gotcha, so there were already some free radicals there. And then, is it the case that the pairing of those two molecules (aluminum, and NaOH) caused a chain reaction because the structure of those particular molecules lends itself to a natural pattern of radicals breaking stable molecules iteratively until you get an explosion due to the heat generated as a side effect?
Amaravora Of couse that doens't happen. I guess adding heat increases the number of radicals and there is some critical mass to get the reaction going, but Im not sure about this tough.
Excellent video. Not a microscope view, but well presented.
Do covalent bonds really jiggle like that?? I've been under the impression the bond immediately becomes stable/solid and the momentum is transferred to the molecule as a whole.
@ 1:12
Stanley Chang yeah, they do jiggle, actually that's the basis of IR spectroscopy
Looks great!
Do carbon to carbon reaction plz.
If only high school chemistry could have been presented like that!!!
Great video. Make more like this
You forgot one very important ingredient - activation energy! H2 and O2 can 'hangout' together, like friends, forever, without anything happening. Energy must be added to start ionization, then kaboom! Fire! H2 becomes oxidized, still ionized into H+ and OH- After energy is removed (cooled) they come together as H2O.
How was this simulation done? What software?
that was a very interesting video.. i love the zoom ins and outs
This video is Radical!!
But where did you get that captivating baritone voice?!
Sounds like an American Liam Neeson!
I have a very specific set of skills.
I will find your Oxygen atoms.
I will bond with them.
And I will burst into flames!
Would've been cooler if you included the hydronium ions too
Excelente!!!
Excusing the artists licence 100,000,000 X microscope, this was very good. If only science had been taught like this when I was at school! I've never done the hydrogen experiment, so that's on my to do list now! I don't think we have drain cleaner like that in the UK though!
i wish this way of teaching was available 15-17 years ago...i would have done better in chemistry in school.
The things you can find on youtube these days..
Makes me wanna say 'back in my day, we didn't have all these fancy educational videos, only boring old textbooks!'
309 radicals couldnt find a pair for their lonely electrons
908 by now ! :))
980 by now
Very good video!
well done! nice video
Amazing. Hydrogen is highly explosive and Oxygen is highly explosive. Mix the 2 together to put out fires... :-/
This video states when oxygen atom meets H2 molecule, it doesn't produce H2O immediately, instead it creates H and HO. HOWEVER, it does not explain WHY!
Excellent video. But probably instead of Microscope you should use the term Magnification.
Such a high quality video for such a small channel.
I would hope pretty much anyone would know that a hundred-million x microscope can only be hyperbole, a story telling device. To say that it is a deliberate deception is being overly literal.
Awesome visualization!
thanks from heart to who are all working for this video.
thanks from heart to who are all working for this video.
I liked it anyway, because the animation was pretty good.
I never knew Hydrogen-gas is flammable. I thought Oxygen-gas was flammable (that happened in Apollo-1)
Is this an app that I can use to run my own chemical simulations?
this is so amazing
What if that was done at absolute ZERO temp.? Probable nothing happen, cuz it takes energy to get the reaction going.
What happens when the single hydrogen atom with unpaired electron meets a OH radical? Do they form water molecular?
They do.

So many people missing the point with this. It's clearly a visual representation which has been made so more people can have a better understanding of how this complex process works. Thank you for posting this.

Exactly! Videos like these are really valuable, entire movie budgets should be rerouted to make content like this, and then they should be incorporated into great works similar to Carl Sagans: A Personal Voyage.

@geirtwo stfu, putting in 50 mil for something as short as this is stupid. Also the title is misleading, shouldn’t call itself a simulation.
Wayne Breslyn - 2022-01-07
@geirtwo I agree completely with this comment and it is something I've often thought about myself as a teacher and YouTube creator! My guess is that creating content such as this for general chemistry would cost much less than the budget of a small movie, especially since distribution could take place on existing platforms. An if it was released under a Creative Commons license it would really have legs.
