The degree of preparation is astounding. Every demonstration rolls off like clockwork. It is designed for all ages. It is not condescending. Very well done.
no
bad roedy
Have you also noted that they don't consult or hesitate
@catothewiser I'm going to assume he knows what he's doing
@catothewiser Perhaps you're correct.. Time will tell..
Superb, I think these lectures should be shown to children BEFORE they start formal chemistry lessons to make them WANT to learn. Excellent presentation and in a way that makes it easy for people to understand and enjoy.
Should that be offered to Children, in the Servile or Liberal Arts format. You leave your indoctrination centres a Parrot & no more. You leave University a smarter parrot, with a debt ridden piece of paper, that is waved under the noses of your future Slave owners.
@@uppercut2246 -he said FOUR YEARS after the comment was posted.
@@juicecup2545 And that's besides that these demonstrations are obviously meant to inspire children to learn and question the world around them rather than parrot o[r] be slaves to some machine. I feel sorry for people whose lives have been formed by such a deep suspicion of everything that even the idea of questioning the world around us is somehow being a "tool of the man."
Mark T dude they do I’m in 8th grade and we watched some of this video in class and now we have to watch the rest of it on our own I’m in class rn and this doesn’t make us want to learn about this or anything else trust me we don’t
@@angelmcglaughlin4506 Soo, what would need to happen for you to be more interested ? Honestly curious. I personally thought the experiments, though simple, scratched a lot of important topics, while being quite appealing to watch.
40 years ago these video would probably have changed my path and career. Science is there and it's free. Just consume it. What a world's change in a few decades.
Science and chemistry kept me employed for a large number of years, I retired many years ago and looking back, was glad I took Chemistry and Sciences at school, watching this,amazing lecture should intrigue and lead young students to the sciences.

The RI lectures are the best. I wish more universities would make an effort to disseminate such wonderful content as the RI does. Also I bet the kid who got the silver-mirrored flask will be in one of your classes in a few years. Keep it coming!
All of Professor Bishop's lectures are fantastic. Both children and adults alike are just enthralled.
Did not expect to sit here for a full hour and watch. Totally worth it.
Yup. Except I watched at 2x so that I can rewatch the parts again if I didn't understand and read comments without having to spend extra time.
Ya, I didn’t even realize it was that long when I started it, watched it all, though in 2x speed.

Great job thank you. Have done similar myself when inspired, know how you feel. Good to have the correct spellings.
These kind of demostration and lectures for public and spevcialy for children let me have yet hope in humandkind. Thank you so much
Humankind has ever failed; hope in God !
I *love* professor Chris Bishop's lectures! I wish I could hang out with him and discuss chemistry and other sciences, he's a fantastic educator with a sharp wit! :)
Professor Chris Bishop: I am 64 years old and your making me wish I was a kid again. The excited inspiration of the faces of the children, wow. If you had been there with this demonstration when I was a child would have inspired my life into a completely different direction. Thank you for inspiring the this next generation of scientist. Who knows what the end result will manifest.
"Chemistry is the study of matter - but I'd prefer to see it as the study of _change_. Electrons change their energy levels; molecules change their bonds; elements combine to change into compounds. Well that's all of life! It's the constant, it's the cycle. It's solution, dissolution, over, and over, and over. It is growth, then decay, then transformation!"
- Walter White, from Breaking Bad (slightly paraphrased)
Demonstrations such as this were what made me fall in love with chemistry (and science in general) as a kid. Sure, changing the color of a liquid is all nice and whimsical, but what really fascinated me was the fact that such reactions were not _magic_, but could be clearly explained and broken down into steps.
Or the study of Matter through change
+StrunDoNhor The study of change is calculus
StrunDoNhor mmmm well it's also the STUDY of chemical and physical properties.
verrry trrue my frriend
StrunDoNhor Chemistry is the study of both matter and its change.
Hope that Chris and Chris are thoroughly happy with the current 3.5m views that their so well planned lecture deserves. Sure that a few of those young people in the audience were actually inspired to study chemistry in more depth as a result.
What a great way to get kids interested in chemistry, and science in general.
Not a single bored face in the audience. Fantastic stuff.
Best introduction lecture to chemistry on youtube and probably ever.
A joy to watch this passionate guy in his curosity lab . Kudos , RI !
This was the most beautiful video I watched on CZcams. Ah, chemistry is truly magical.
Unfortunately, I prefer facts based on my everyday experience, as oppose to handing my authority over to establishment. You can keep your Magic for the children.
@@uppercut2246 ahhh, c'mon...
@@uppercut2246 Fortunately, facts do not care about your biases. They are just facts.
Much appreciated, lectures such as these take enormous preparation, a hugh thank you to all involved.
Oh My GOd!
The Best Thing I have Ever Seen.
Nicely Done by our great professor Chris
Thank you Ri for sharing for free
Chemistry is amazing. Seeing how the elements react with each other is so fascinating. It really does help us to understand the world better. The advancements in the medical field due to these discoveries is crazy. This is why I love chemistry.
Amazing. We need teacher like you.
The only lecture I have ever been able to sit through from start to finish without fall8ng asleep.
this is one of the best lectures i have ever watched!
Same here, Franchy.
About acid and alkalain, after scool)))
Yeah me too
@@sockington1 like?
In ua I iis and my friends have
It is good to know that there are some CZcams channels that you can trust.
Yup it's Royal Institution. Well funded I guess.
@@randomdude9135 @
science and chemistry never stops bringing a smile to my face in how it changes everything around you.
So glad this appeared on my feed. The RI Xmas lectures where a huge inspiration and influence on my early blife.
The demonstration that starts at 12:25, this is the chemical reaction that astronomers used in the past to make their telescope mirrors reflective. Today, they evaporate metals, usually aluminium, with high temperatures in a vacuum and let the metal vapors condensate on the surface of their mirrors, but in the 19th and early 20th century this chemical reaction was how they did it.
Oh thankyou
this is one of the best lectures i have ever watched!
The mirrors at Versailles were made by Venetian artisans with that method...
@@rayoflight62 That's true. And silver makes better mirrors because it's more reflective than aluminum. However telescope mirrors have a serious problem that other mirrors do not. The reflective surface is on the side of the glass being used, rather than on the opposite side.
Silver oxidizes fairly quickly compared to aluminum. So astronomers used to be plagued with frequent re-mirroring their lenses. That's not a serious problem if your telescope is 12 inches, but for very large ones it's a major undertaking. For home mirrors that's not a problem because we look through the glass at the image through the mirrored surface. So after applying the silver you could simple paint over the silver to prevent oxidation.
Some sign painters use this to gild silver lettering, also done with gold, called Angel Gilding. Auto headlight buckets were silvered this way, before sealed beam lights. The buckets would tarnish, turn yellow and produce dim light and have to be redone. A friend of mine restored an old Hupmobile and we had to find someone to resilver his headlight buckets. The lights on my '35 Dodge were dim and I got tickets, but I just converted to sealed beam. I imagine many millions of cars were junked only because the lights had got too dim to see at night.
Magnificent lecture presentation and beautiful displays!!! So appreciate all the work and knowledge that went into it all!!!
Amazing chemistry and also introduced molecular physics and a touch of quantum physics ... brilliant..!
Wow!! what an amazing lecture on the beautiful curiosities of chemistry that kept hope alive for growth in the field and pursuit of more knowledge. Human kind's journey of science has been amazing
Chemistry needs to be taught like this.
Royal institution , two words,'YOU ROCK!'
Acid Base -> combustion -> reverse & oscillating reactions -> and many more..
All covered beautifully in one video..
Just Awesome..
They should do this presentation at every school around the world, That was awesome! I watched every second of that video from start to finish and didn't even think about skipping ahead once.
This is why I love Chemistry !
This makes chemistry so interesting. Wow, Thank you!
The Royal Institution produces such great content that's extremely entertaining and informative. They're not as technical as I'd like, but that's probably for the better. Getting the public interested in STEM is something I love to see.
Oh my, I'm watching this in class and I'm in shock. So cool!
Great video, I remember going to Liverpool university Xmas lectures, in 1957-8, they were also very interesting and inspiring for a young kid. Nothing boring about chemistry, they must have inspired many a youngster.
I had to take part in a show like this when I was asked to supervise our secondary school's Open Day for the chemistry department. Ended up doing many of the demonstrations here to wow the parents and the children. That was a great day. :D
Informative, entertaining, and interesting. I remember watching this about 8 years ago and it was worth watching again. Excellent.
Professor Bishop is amazing. I was fully immersed for the entire lecture. So brilliantly presented and thoroughly engaging! Added to my fascination was the lecturer’s uncanny resemblance to a certain music legend, Mr Phil Collins.
That was amazing! loved it :)
wow.this was just cool. bud also sad that this vid only got 950000 clicks by now.Very nice show Mr Bishop and thanks for the upload.
Very well presented, as what was said in a previous comment, wasn’t expecting to watch a whole hour, but I was hooked! What a fantastic tutor!
Found this video by accident. As soon as I was about to close the video, I ended up watching the whole lecture. MAGNIFICENT !
I like how the best demonstration in the chemistry lecture is pure physics (superconductors)
Yeah but I found the crystal coming out impressive.
This made me feel like a kid again! Loved it. Its a rare occurrence to recapture the feeling of youth! :)
Sounds like a Chemistry symposium like this around Christmas time would be fantastic. Everyone can make ornaments with the shiny inside or something decorative in that spirit of cool stuff.
The great Faraday has set a wonderful tradition and Prof Chris Bishop is carrying it on in all glory. Science has got back its good time. Thanks to Royal Institution for upholding the standards.
I wanted to sleep so started this lecture now I'm more awake than ever
Same Here. Broo😁
This is absolutely amazing! I've seen most of those before but they were presented really well.
This was really cool, I did not expect this would be so entertaining and educational.
Bravo. Great work Professor Bishop. The way that the greats in chemistry have been spawned is through an inquisitive mind. These excellent lectures by example invoke in a young mind both the excitement of chemistry and the need to understand the how and the why. They can drive a youngster to develop a passion for the subject, leading to a possible career and the making of new discoveries in chemistry in later life that benefit all of mankind. This is how some of the greatest research chemists have been initiated, by attending lectures just like this in their formative years. These lectures are by the way most entertaining and informative to adults too. I really enjoyed this lecture.
Before I started to teach any chemistry, I always used to have two solutions - one was a solution of lead nitrate and the other was a solution of potassium iodide. I would ask the class what they might expect to happen if the two solutions were mixed together. No-one ever got it right (for non-chemists, you get a bright yellow solid, a precipitate, formed. This is lead iodide. ) The result is so unexpected that it would immediately grab the attention of the class. Chemistry is fun, not just a collection of apparently unrelated facts. I think that Professor understands this very well. His lectures are always full of fun.
Very long lecture but didn't feel bored at all. Interesting experiments and very good presentation.
What a Wonderful Lecture. Thank you. One of the few things I have watched on CZcams and I didn't skip through. Had me the whole way through. Loved it.
I've watched a lot of science demonstrations - this one is beautifully prepared - you know it's good when you hear the audience actually gasping and going wow!
Far better entertainment for children than going to the circus and get Clown-phobia.
Coulrophobia
sure abt that??
That is a rather specific observation.
Smoked a few bowls... and this had captivated me for the entire hour!
Absolutely Amazing! Thank you for sharing your knowledge and understanding. Great job!!!
What an awesome display of showmanship, I watched the whole thing and now it's time to hit the share button!
I would gladly pay the price of a baseball game to expose my children to a live demonstration like this. Brilliant!
For this to make any revenue, it would have to be priced at the level of premium bleachers for a playoff series. I almost wonder if RI could afford to pay for all the glassware cleanup on the audience revenues alone. Some harried administrator invested an entire _week_ dealing with the local fire department before this was authorized to go ahead. The only thing that makes this cheaper than sports is that they didn't need to fly a contingent of 40 players and staff on a charter flight to some posh hotel. (You can see how the assistant in the white coat is all about posh, even though he probably bust his hunchback in college as much as any athlete ever bust his hump.)
Fire chief: Hey, are there _any_ special considerations in deciding which fire control system to deploy first?
I'm just spit-balling here, but my first bid is that there was a four-person HAZMAT team hiding in the wings-all with graduate degrees in chemistry-and that at some point they sat down with a corresponding team of four professional HAZMAT firemen and firewomen from the local firehall for a three-hour coordination meeting, roughly two weeks ahead of time.
Also, do you think they kept the nitric acid and the giant hydrogen balloon and the magnesium foil and the liquid oxygen and the white phosphorous all on the same shelf back stage? The internal HAZMAT team was probably gophering these materials JIT throughout the demonstration (just in time) from separate rooms, off separate hallways.
At one point, I was halfway expecting him to demonstrate burning sand or concrete in a chlorine trifluoride atmosphere. (The ultimate HAZMAT 11 on a scale of 1 to 10.)
That definitely convinces me the rest that I want to be a chemist. I was already 90% sure but whabam i am totally sure. fanfriggintastic demonstrations, wish I could have been there personally.
Three years has passed by since you made this comment. Are you by chance still on about being a chemist?
Leif Duncan Urdaneta I guess we’ll never know..
I think he was just excited about the Illudium Q-36 explosive space modulator!
Thank goodness for Duck Dodgers
This is the lecture that just keeps giving.
Magnificent lecture presentation and well but together. I wished that we had this kind of facilities 62 years ago. Thanking you for all that work, very much appreciate.
amazing professor chris! Your book PRML was my introduction to machine learning :)
my teacher Ms.Gregory had us do a work sheet on this..kind of cool
I used to watch the Christmas Lectures & am so happy to have found this channel. Many thanks! So much easier to learn when its fun!
If you'd still like to scratch that Christmas Lectures itch, we have a present for you - www.rigb.org/christmas-lectures/watch We are releasing a new series every month and the hope is that by 2020 all past lectures will be online for free for everyone to watch. Our licensing agreements mean that we cannot put the full lectures on CZcams, but we hope we've given them a nice home.
For younger children to see this video, maybe even those teaching, will all benefit from learning how to keep the audience receptive to the lesson, which this Lecturer is so knowledgeable and energetic. To impart really interesting concepts with chemicals, so crucial to see while information is learned. Excellent lecture.
The clear liquid that instantly turns black was amazing. I was saying wow like the younger kids in the audience
I was gonna make a joke about sodium and hydrogen, but NaH...
Sophia Solvett sodium hydride
Funny!
Good one Ms. Sophia.
Same procedure as last year?
I told my friend a joke about Potassium, he said "K".
Lol. Good one!
This was the best chemistry lesson I received .... Ever !
really great interesting lecture - I got use of each part of it to make it as starter activity of my lessons and the students paid great attention to the explanation of the subjects.
so when i feel i'm in love with chemistry, is it a chemical reaction ? and if so, is it reversable ?
**=** Strange echoes sound between 0:15 and 1:45, lol 😂
34:26 Wow, rocket nozzle 😁
35:37 Interesting inverted reaction, CO2 to C by Mg making MgO, and the final reaction 1:06:50, about chlorophyll chemistry 😃
superb way of creating love towards chemistry
Thanks Chris Bishop, Chris Brackstone, & uploader :)
Wonderful lecture, however two points are misrepresented, when the solution went from liquid to crystal that was not a chemical reaction but a phase change of a supersaturated solution (technically thermodynamics). Second the superconducting magnet also did not undergo any chemical change instead it was a physical one as it was cooled. Otherwise outstanding.
Watch this with your kids!
Andrew Seymour what if u have no kids
Very enjoyable, well presented with the right blend of chemistry and humour. I was a chemist and still found it informative.
its learning like this getting kids involved and giving them something that is needed far more around the world to create a much better interest in our facinating world
"Nitric acid also acts upon trousers." Glad you figured that out so that I don't have to lol
It doesn't matter were I go... Entropy is going to get me. Even on youtube. Earlier today I found a Greathammer in Guild Wars 2 with the name Entropy. I JUST WANTED TO HAVE FUN!!!! WHYY!
This is a wonderful way to guide young minds towards the path of knowledge..
What a thrill to have you as a teacher!
When I started watching I was like: "Ill go to bed in 10 minutes"... now I realize its like 5 am xD
This is the exact same thing that happend to me.
why u going to bed at 4
I want Kevin Spacey to demonstrate chemistry to my school...
+Jacob Gray What a strange thing to write.
+gluefrog78 I see your point
how so?
you want an actor to perform at your school

What an excellent show! What an excellent introduction to the world of chemistry! Where were such teachers when I was in school? ;-)
An hour of very interesting stuff, and presented impeccably
24:31 I certainly hope he doesn't have any liquid hydrogen in there. Imagine the "BOOM!" if it got sparked.
I had to rewatch that a couple times when I heard it go from Hydrogen to Nitrogen.
@@onradioactivewaves Yeah, he does say hydrogen a few times then says nitrogen just after.
Didn't we know chemical reactions can be reversed from the moment he explained the hand warmer?
Thats not a chemical reaction. In a chemical reaction the molecule change, i.e. new substances are created. In a hand warmer it’s still the same substance, it’s just supersaturated in one state and crystallized in the other.
@@salmjak oh I see
I was thinking the same thing along the entire lecture.
As someone who has already taken a full advanced regiment of chemistry classes in uni, I still watched this because they teachers charisma and jist satisfying way of teaching.
Fascinating stuff and superb presentation.
Nile Red prepared me for this lecture. When he set off the reaction at about 7:59, I knew it was a clock reaction. The nylon was obvious as well, thanks to Nile.
24:37 kept on saying liquid hydrogen and then finally switched over to saying liquid nitrogen without realizing it.
Wrong, Liquid nitrogen (-196°C) is absolutely able to liquify oxygen (boiling point -183°C)
24:30 He said "hydrogen" and the closed captioner typed "nitrogen".
27:20 he also shortly after that says that there are 2 "kinds" (Allotropes) of Phosphorus; there are a lot more and usually you count at least 3 - White, red and black phosphorus.
I was quiet scared when i heard he was going to make liquid oxygen with liquid hydrogen, that seems like a recipe for disaster in a lecture lol
Yes! You do Not want to 'play' with White phosphorous, as it readily burns very Hot in air, and the P2O5 that forms is nasty stuff by itself! (See: en.wikipedia.org/wiki/Allotropes_of_phosphorus#White_phosphorus for more info.)
Wonderful! Thanks a lot for posting it. While being amazed one can never escape the feeling that this is indeed only the tip of the iceberg!!
What an amazing lecture. Thank you Professor!
24:30 transition from liquid hydrogen to liquid nitrogen :-D
I caught it too and it really threw me. The lecture is so well prepared, it's really difficult to call them out on it.
