Great job thank you. Have done similar myself when inspired, know how you feel. Good to have the correct spellings.

"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.

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.

@@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.

All of Professor Bishop's lectures are fantastic. Both children and adults alike are just enthralled.

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.

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.

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! :)

When I was a little girl, my father worked in a machine shop where they made parts out of magnesium. He brought home a small piece of magnesium home, and set up a demonstration. He had a bucket full of water, and a highway flare. He lit the flare, and used it to set a bit of the magnesium on fire, warning me not to look at the bright light. He then dropped the piece of magnesium into the bucket of water - it kept burning, because the magnesium was able to react with the oxygen in the water. He liked to teach me about science.

Informative, entertaining, and interesting. I remember watching this about 8 years ago and it was worth watching again. Excellent.

Chemistry needs to be taught like this.

Magnificent lecture presentation and beautiful displays!!! So appreciate all the work and knowledge that went into it all!!!

So glad this appeared on my feed. The RI Xmas lectures where a huge inspiration and influence on my early blife.

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.

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

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 chemistry and also introduced molecular physics and a touch of quantum physics ... brilliant..!

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!

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.

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.

This is why I love Chemistry !

Found this video by accident. As soon as I was about to close the video, I ended up watching the whole lecture. MAGNIFICENT !

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.

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.

What an awesome display of showmanship, I watched the whole thing and now it's time to hit the share button!

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.

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.
