Congratulations Neil. Technicians are largely ignored but we keep stuff working and carry out much of the work required by Scientists and Engineers to push things forward.
Technicians are just as important and none of you should feel lesser ❤
Love technicians, wanted to be one but wasn't hard enough! Now I'm a cook, though, so similar scenario. Great channel innit
It seems all the most important jobs are VASTLY under appreciated, like garbage collectors or teachers or ANY blue collar job for that matter.
If you don't have a fancy title and a fancy suit you must not do anything important, right? So sad...
Why isn’t Neil a chemist(i.e not pharmacist) or Professor of Chemistry?
@@roberttelarket4934 I don't know if he's a professor but definitely a chemist. It's just a different career path. Loosely speaking a professor is employed to lead research in a particular department and teach, etc. Technicians at universities are more part of the infrastructure and work behind the scenes, they know how it all works, how to fix it, how to not break it and so on. When I was doing chemistry I would always find myself learning a lot more from the techs. Great bunch.
I fondly remember Neil from my time at Nottingham University as a PhD student in the 1980s. At one time, I was doing some experiments with quite large quantities of metallic sodium. I remember disposing of the sodium using isopropyl alcohol in a fume cupboard. I think it was the very same fume cupboard as in the Periodic Videos. Congratulations to Neil for the Royal Society Award.
Nice to see Neil getting honored. He's one of the main faces of this channel and deserves recognition for his part.
He does! Listen how the narrator is talking about Neil doing everything! Look how I don't know the guy's name but I know Neil's name :)
Yes ! I fully agree.
Please do more things that keep Neil satisfied!
I like the implication that Neil is some dangerous force that has to be satiated with fun chemistry. It seems pretty believable really
Feed him some villagers from time to time
Such as reacting boron trioxide (B2O3) or boric acid (H3BO3) with Magnesium nitride to create an ultra hard cubic Boron nitride. ;)
@@koenth2359 You can't satisfy a dragon with just a few villagers. He needs more!
Such a lovely demonstration of scientific communication, too: someone writes in with an improved design for the reaction, they test the improved design, and then they discuss how the improvements work and why.
As always, When Prof., Neil, & Brady combine, they cause a reaction that never fails to make our minds glow brighter.
Well said !
As the O2 and N2 are consumed, more air is drawn in through the spout on the beaker. To get clearer N2 combustion, you could pour some LN2 onto the benchtop to ensure that the makeup air is actually N2.
this bothered me so much lol
Very nice experiment and congratulations to Neil, the Hucksbee Award is more than deserved!!!
Very cool experiment and huge congratulations to Neil for his well-deserved recognition. Neil, and folks like him who make all this work, do not get enough praise.
Hamiltons dad rules
This takes me back to 1959, in the garage with my father, when he asked, "Do you want to see something amazing?" Then he lit a tiny strip of magnesium and produced the brightest fire I'd ever seen and gave me another brilliant childhood memory. Thanks for reminding me.👍
The basic experiment - burning magnesium in nitrogen was cool and stuff. But the idea to add a candle, to proof the oxygen burns first, was brilliant!
Congratulations to Neil! Well deserved recognition.
The experiment with the candle also consumed O2 leaving less for the magnesium, which may have given it more opportunity to react with N2, resulting in the nicer yield of Magnesium Nitride. Would have been nice to see the reaction with an active source of N2 gas!
Yes it would be interesting to see if the magnesium would react to completion with an excess of N2. I also wonder if external heating while in the N2, without first burning in oxygen, would work.
@@robertroy8803 I agree. A resistive heating element should be able to reach and survive at the 850C or so this reaction apparently takes. Then of course it brings me to wonder if you could use a magnesium ribbon as the resistive heating element itself in the pure N2 atmosphere. That would be fun to try out.
Yeah similar thoughts, tungsten wire inside to heat the magnesium and flush the whole container with N2 before starting. Would be interesting.
@@robertroy8803 Ignition by laser might work when lowered in the N2 vapour? This is more a question because I'm no expert.
This was the basic idea of putting a candle in.
This is so cool. I wonder if you can get ahold of other alkali/alkali earth metals to see if you can get nitrogen to react with them and see how easy it is?
alkali metal nitrogen compounds tend to be a bit excitable.
or what if other gases, like helium or xenon is in the beaker, instead of air
@@Paonporteur thanks for the info. That would be cool though 😁
It is always of the utmost importance that Neil be satisfied. He’s a treasure and I appreciate his contribution to your videos.
Old man learning something new. This is why I love this channel!
At 80-plus, I quite agree !!🙂😉
I love Brady's Videos! the comments section are one of the few places left on the net where people are still decent and civil with each other and there are little to no trolls
I reacted magnesium with nitrogen in a spectacular experiment in high school (Sweden, STEM focused program).
We used fine magnesium powder in a ceramic crucible with a perforated lid.
First we ignited the powder, and let it burn openly for 3-5 seconds, while stering the burning powder with a metal spatula. We were then supposed to put on the lid, but for many of the groups, the magnesium actually reacted with nitrogen from the open air, no lid necessary.
We performed this experiment in groups of three, so I got to actually steer the burning magnesium powder myself! For a 16 year old high-schooler, this intensely green and sparkling fire was exciting indeed, and was part of what made me decide on wanting to become a chemist!
My father used to end up with unused scraps of magnesium and demonstrate how they burn to us as kids every once in a year or so. He would say "Don't be afraid it's okay! Smoke is fine too! You shouldn't need magnesium for a year. Just don't breathe it too close and don't touch it!" then he would explain how it was weaponized and caused horrible burns and pain.
He was a crazy chemist.
sounds more like phosphorous than Mg, though smoke from both is fairly benign.
@@Muonium1 Magnesium is used instead of phosphorus in Geneva-compliant incendiary munitions as well as in tracer burners, i believe.
@@Muonium1 That's a ridiculous claim to make for either magnesium or phosphorus. Magnesium oxide has properties similar to quicklime (aka calcium oxide), so if you breathe in magnesium oxide smoke, it will rapidly react with the moisture in your mouth, nose, throat and lungs to make magnesium hydroxide. This is mostly insoluble, so the inside of your lungs would get coated with a layer of it - if that happened enough and a thick enough layer formed, it could suffocate you by blocking your lungs ability to absorb oxygen.
Phosphorus oxide smoke is orders of magnitude worse - it also reacts with the moisture in your mouth, nose, throat and lungs, but this time the product of that reaction is phosphoric acid. This is water soluble and is a fairly strong acid, and will pull fluid from your lung tissue and blood by osmosis, filling your lungs with acid solution from within, drowning you in your own bodily fluids. This is a horrible way to die, and is why phosphorus munitions are classed as chemical weapons if used against people, which is listed as a war crime by the United Nations.
So in both case, hardly benign. More like the complete opposite.
@@lloydevans2900 maybe actually touch grass once in your lifetime instead of incessantly making a fool of yourself on the internet? just a suggestion. I've been in classrooms literally countless times where both of these experiments are done, breathed the oxides of both, and like literally everyone else in the room suffered ZERO ill effects - shocker, I know. There are hundreds of videos on youtube alone of the 'philosopher's stone' phosphorous burning experiment being done in lecture halls and classrooms outside of a hood with the room filled with the resultant smoke. no one died. Presumably you've also never read the label on a bottle of Coke before either. Amazing.
I’ve been watching the prof for years and love every time I get updated about a new video. This video is no exception. Keep up the great work at the university yall!
This video made me remember my chemistry teacher demonstrating the same reaction but with a much larger amount of magnesium. The "mountain" was about 11 cm wide by 7 cm high and the reaction was quite spectactular :D
Now, about 25 years later, having studied chemistry and working in product safety, I cannot believe he did that in the class room outside of a dedicated fume hood :O
Edit: added missing word
Yes - Health and Safety, less fun but Chemists live longer.
Back in the Dark Ages of the early 1960's, a year before my college course in Inorganic Chemistry, a professor had a serious accident with burning metal powder in the classroom.
That demonstration involved pouring liquid Air onto a pile of Aluminum powder. The powder was placed on a slab of aluminum, about 1/2 inch thick, set over a lab sink. The same demo had been performed for years, without incident. *This* time, it detonated rather than deflagrating (normal burning)! The professor was thrown back against the wall, many windows were blown out, and much of the class was temporarily deafened. The aluminum slab, kept as a warning for the future, had a dent over an inch deep, from a completely unconfined explosion of maybe 20 grams of Al powder.
The irony of the situation was that on the prof's office desk was the current issue of a chemistry teachers' journal, warning about the dangers of this very experiment; no one had read it yet...
What a cool experiment!! One of my favourites from this channel.
And, congratulations to Neil...very well deserved!!
WOW! That is a beautiful reaction! This is fantastic footage, thank you!
Always a happy day for me when a new chemical demonstration from Sir Martyn and his colleagues appears. Starting over 60 years ago with a chemistry set in my youth, I have always been fascinated by chemical reactions and the characteristics of the elements, and I always enjoy learning something new from these delightful demonstrations!!
Wow, great collaboration to get the experiment to work successfully. And congrats, Neil!
Beautiful to watch burning
Professor, Brady, Neil, James -- Very nicely done! Thank you, and best wishes to all. VH
Wow awesome Brady!
Dr. Brady, I see we are tapping into our roots across channels.
Great to see!
great video as always!
These videos have kept me well interested in Chemistry, long after my schooling years. Thank you.
I love your stories.Yes man,show them!!!!!
Congrats Neil! I always enjoy listening to the Prof., but Neil brings all those words and ideas to life.
Thank you for sharing everything with us always a great video good to see the professor and Neil
Seeing this simple type of experiment really demonstrate why we as humans thought that alchemy was so possible. We now understand most of that "magic" that grabbed our curiosity long ago. Watching you recreate them brings some of that magic back and it's enjoyable to watch.
Yess please I love this channel my hands down favorite Brady thank you so much with blessing us with such amazing beautiful minds sir Martin is my favorite professor as I’m sure he’s many others please keep up the great work thanks again Brady
Love these videos and love love love Martyn! Been watching for so many years, his voice gives me such nostalgia. He looks as young as the day I first saw him ❤
So happy to wake up and be greeted with a new video from the professor.
very cool experiment n congratulations neil❤🎉
beautiful reaction; Congratulations Neil!
Always good to see you Professor :)
This was a very satisfying video to watch.
Wonderful! I'm going to see whether I have some magnesium granules in my prep room- this will make an excellent demo for my students and will trigger lots of discussion!
Thank you, as always, for the amazing and interesting video. Every time I see P.V. put out a video I know it's gonna be a great day :) Cheers and stay safe!
I love these videos so much!
Profesor has been trying to do this for so long and finally succeeded. Maybe it will be similar with Coca-Cola - one day he will successfully drink it for the first time;-)
I'm happy to see the reaction!!
I failed chemistry and have never had that much of an interest in it, only found this channel when I was curious if pianos actually explode, but Neil comes across as such an intelligent and knowledgable man and has the ability to keep you watching to learn even more. Congratulations on your award Neil - reading the other comments I can tell how much you mean to others and how much people appreciate your work. Great video.
Of all the things I've never considered - whether a piano can explode has never been one of them. What is the answer please?
Forgot to add, I love watching your videos because I learn so much and become more curious about this wonderful universe.
Enjoyed this very much thanks!
That was a really interesting experiment. I'm glad you were finally able to experience it.
Wonderful reaction, and very clear explanation by the Professor.
How? So many I don't knows and maybes. The guy repeated the same experiment for 25 years expecting a different result. Fire him basically.
Great video, as usual 👨🔬
I used to watch your videos years ago, and then I forgot the channel name after I cancelled my Internet for a while. I'm subscribed now, and I just want to mention how much I like your interesting, intelligent and fun videos. Thank you.
Glad you’re back
Beautiful and fascinating.
This channel is a home away from home for me.
Awesome! One of your better experiments.
We quite like it when Neil is satisfied. Excellent and very interesting experiment.
Although I'm certainly not a chemist, I always enjoy the videos on this channel. Very interesting content.
Very interesting video.
Thanks to all who make the channel possible.
This is my favourite kind of reaction content on CZcams.
I am glad you finally got to do it successfully!
That was excellent. Thanks
Brady, it's gonna be perfect if you write down on professor Poliakoff's explaination at 5:00 like what you did at 1:40
This is a very cool experiment and explaination. Like watching scientist doing observation and thought process on a real time. Thank you
Giving Neil that award is not only well-deserved but clever; you know his acceptance speech will be the shortest they've ever heard!
Fascinating, thanks to Karsten.
Sometimes i check up on the prof and sometimes i wanna learn.. either way im glad i get both in each video.
I love that plume. This is one of my favorite reactions I’ve seen.
Very nice .it is helpful
Great video
That was really cool to see it relight and get even hotter!
That was really interesting!
The point about small atomic sizes and high charges was really fulfilling to learn. It's one of those simple ideas that explains a whole lot.
A very well deserved award to Neil, congratulations!
This was a great episode. I think this doubled my knowledge about magnesium and nitrogen.
The experiment itself makes me think it would be an easy layman demonstration.
That was very interesting!
A new video from Periodic Videos is a celebration. 🎈🎈
Super! Thank you very much! This I am sought longer!
We did this in freshman chemistry, oh these many years ago. Ended up writing my dissertation on polymerization catalysis, and then had a nice career in industry.
Thanks. Be well.
Prof.The Best! Cheers Martin !!!Your Serbian fan.
Congratulations Neil!
Thank you for sharing these demonstrations. I have always loved chemistry but ran out of brainpower for it before university - balancing redox equations was a bit much for me, let alone remembering which catalysts one uses for organics reactions. Seeing these performed and explained so clearly is the next best thing.
From time to time I think about this reaction after it was mentioned before. So awesome to see this finally happen
I would love 💕 to go to Your University!!!
Top man Neil, well done.
I did that experiment with magnesium turnings as a freshman chem student. Not because I’m super-smart or anything but because the text we were using said to use them. What I remember was the odor of the nitride: similar to the odor one gets after an electrical discharge across metal contacts, or when a tungsten filament light bulb breaks while in service.
The candle is a very nice touch to this experiment
I don't understand chemistry, but the chemical reactions are exciting to watch.
Btw i love your videos my dad and me watch them every night if you see this then tysm for the vids (: keep it up (:
i love the color of the magnesium burning under the beaker. Thats so cool
Great reaction
So cool watching something considered completely unreactive doing a reaction with so much energy being released. Super cool!!!
Unreactive? Many of the most explosive things are based on nitrogen. Anfo. Nityroglycerin. TNT. C4.
What I found fascinating is the absolutely laminar flow (1:44 for example, again at 4:54 and again at 5:33) of the "volcano" plume before breaking down to turbulent flow around 1:51, 5:03 and 5:41 respectively. Great experiment on so many levels.
This book was my entry in chemistry ❤️
Congratulations to Neil! 🎊🎈🎆👏
Wonderful
Die beste science videos. :)
Awesome 👍 May this work with other metals too, like zinc or calcium or sodium?
I love the shot @0:39. Neil with The Professor behind him, pointing out the new detail that will solve the mystery. :D
One video that I would find very interesting is how disinfectants came to be a staple in the medical field, and the chemistry involved in that. I just finished reading „The Butchering Art“ by Lindsey Fitzharris where he describes how Phenol (or „Carbolic Acid“ if you prefer the old fashioned name) became the go-to substance of the early 19th century for disinfecting everything. I think there is quite a bit of interesting chemistry around Phenol that might be worth exploring a little bit.
