These are extremely well done

I'm watching these whist slightly drunk and im bloody loving them! So interesting. Really speaks volumes about the quality of Faraday's lectures that they are still so captivating today. Really love your work, keep it up guys, thanks!

Your voice, reading Faraday's words, sounds just like the subvocalisation my brain gives to Edgar Allan Poe :) Fantastic series, by the way. Thank you!

Thank you for your excellent videos. Is there no one who still says thank you among KZreadrs? At any rate Thank you, that was a lot of work to produce.

so much science in one simple candle. amazing

I guess it's a sign of the times that Faraday wanted to introduce CO₂ using limewater, but I felt like he was introducing limewater using CO₂.

The videoes this genius makes should be made mandatory to watch at school. Excellent videoes

I love these videos thank you for making them. I have learned so much. The things we take for granted every day it’s fascinating

We are watching these in our homeschool while reading a bio about Faraday. They are great, thank you very much for making them. I'm stumped with the emphasis on understanding air pressure in this particular lecture. I understand that the nitrogen in the air is stable and therefore keeps our entire atmosphere from burning... but how, in particular, does AIR PRESSURE affect the candle flame and/or why is air pressure itself important to understand in relation to the burning of the candle? Thanks for any insights!

What matters is the partial pressure of oxygen. A pure oxygen atmosphere would work similarly for combustion _if_ you reduce the atmospheric pressure accordingly - that is, about one fifth atmospheric pressure. There's differences in practice, of course - e.g. combustion also depends on the partial pressure of carbon dioxide, air with nitrogen is denser, the nitrogen carries heat away in convection _without_ being available for combustion itself etc.. But all things equal, larger partial pressure of oxygen means more combustion. You can achieve this by separating the pure oxygen from air, or by increasing atmospheric pressure. Higher partial pressure makes it more likely that individual molecules of oxygen combine with e.g. individual atoms of carbon, and at the same time, less likely the reverse is going to happen - carbon dioxide splitting into carbon and oxygen. Remember, chemical reactions go both ways - we create a bias towards the side we want by changing the environmental conditions, like temperature, pressure or concentration. At equilibrium, both trends are equal - going from A -> B is just as likely as going from B -> A. As for nitrogen keeping the atmosphere from burning, that's not an accurate representation. In fact, the nitrogen is the only large portion of the atmosphere that _can_ burn in the first place - it combines with oxygen to form various nitrogen oxides (though it requires energy, rather than releasing it). However, as you say, nitrogen is very stable - this essentially doesn't happen at ambient pressure and temperature. To get appreciable amounts of nitrogen oxides, you need high temperature and/or pressure - as in the exhaust of internal combustion engines, where it's a dangerous pollutant. A pure oxygen atmosphere wouldn't burn - there would be nothing to burn in the first place. However, many other things would readily burn in a pure oxygen atmosphere - things like trees, grass or _iron_ :) (in fact, iron does burn even in our atmosphere - very, very slowly; that's what rusting is. Iron filings burn particularly well).

These videos are incredible

Cool videos. I started making my own chemical rxns a few years ago because of Faraday's book. I did my oxygen experiment with air and it was pretty quick. Took only seconds to become clear again.

Faraday is becoming my hero

Much appreciated and enjoyable to watch. Thanks!

I enjoyed this, thanks

Cool and helpful I like the book and these videos are great thanks!👍🏻😁

All you people complaining about 6 videos popping up in your feed need to find something else to complain about, these videos are great. Who the heck would want to wait for them to come out over the course of a week?

I liked the bubble blower and the air gun. XD

Faraday really liked the adjective ”pretty.” ;)

As a classical architect, it was little painful to see that marble so easily destroyed.

At 7:10, he says the weight of sure in the room is above a ton. That's a huge room. 2000 lb /(0.0764lb/ft3)= 26000 ft3. Assuming 10 ft ceilings that's a square room of 51 ft x 51 ft.

Didn’t he mean to say “lighter density” though? The air bubbles had lighter density than the CO2 gas they were floating in, no?

What's the explanation for the egg jumping into another bowl? At 10:50

Should we be storing compressed air so we lose less of it into space?

Why did the balloon rise for a bit when you turned the pump off?

Its due to air rushing under the balloon lifting it. In a similar way as the egg.

I'm pretty sure that blackboard "chalk" is made from calcium sulphate, not calcium carbonate. How did it smell when it went in the acid?

+Dan Soper we discuss this on a footnote I the book. In faraday's time -- the 19th century -- blackboard chalk was calcium carbonate. Today most chalk is, I believe, gypsum. I recall having to look far and wide the get the old fashioned chalk for this video. I think we mention this in the commentary video for this lecture also.

So in a burning building should I crouch right down to the floor or should I keep my nostrils in the smoke?

4:45 i was expecting him to say global warming.

12:30 I’m surprised the balloon didn’t pop. I still don’t get how he was able to blow the egg from one container to another. Wtf.

The egg monuver is from Scam School.

"...it is as indifferent to all our organs as it is possible for a thing to be." And yet, even at one bar, nitrogen does give partial narcosis- when people were given iq tests while breathing heliox at one bar, they scored significantly higher. Removing nitrogen makes you smarter- but sound funny. Too expensive for routine use, of course.

I don't think original manuscript included plastic in the demonstration. i wonder how The did the demonstration with ceran wrap in the original lecture.

15:49 I wouldnt say that those materials are capable of producing large amounts of carbon dioxide as it's mainly owing to the oxygen of the atmosphere which is separate from the material? Great video!!

19:00 But if the flask remained as just air, the results would be the same (the flame would have also distinguished). What am I missing here?

@simonb.5624

The results wouldn't be the same in air. He demonstrates this a few minutes earlier: 16:00. The taper burns in a flask of air and is smothered in a flask of CO2. The burning or not burning is a test to determine the gases present in the flask.

kzread.info/dash/bejne/qGV4uaqen9iwibA.html Is that the burn from the soap bubbles on your hand? Great videos, btw.

I do not like the "click" sound at the end of each video. I get to the end, and am moving around with the mouse to Like the video and then navigate to the next video in the series, when - "CLICK!" Semi-consiously, it feels as though someone is nudging me, castigating me for moving too slowly, for not getting on to the next video quickly enough. Ending each video with silence (just letting the music fade out) would be more enjoyable.
