"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.

[@randomdude9135]

Oh thankyou

[@bsocmtomsdcs815]

this is one of the best lectures i have ever watched!

[@rayoflight62]

The mirrors at Versailles were made by Venetian artisans with that method...

[@cheapbastard990]

@@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.

[@tomlord5398]

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.

[@mikethomas2510]

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.

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.

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.

[@afterthesmash]

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.
