This is probably the biggest upside to quarantine. Having regular uploads of Andrew! I just love him! I’d watch him talk about watching paint dry to be honest!
I've got to say, I've turned away from several other "at home video's" but Andrew makes a good show, good science, very nice electro-chemistry, very fine home made battery, and plenty of flames and such. It's nice to see an old, maybe ten years newer than my own drill press of the same make, see the corner of a mid-sized lathe now and then, and that you shop on ebay as do I, and fix cheap not so perfect parts in preference to new ones, great show, all the way around, worthy of R.I. all the way, Thank you
Andrew Szydlo is a fine teacher. I wish I had the Internet as a child. Thankfully, I had my maternal grandfather, the Scholastic Book Club, my local library and some truly marvellous (and patient) teachers.
Marc-Andre Check out all of Szydlo's other experiments at The Royal Institution. I love it when he says things like "Here, we'll just light this on fire and see what happens..." :-)
08:25 - The dramatic way Dr. Szydlo tells that story, I expected him to conclude with something like: "and that's how Volta developed super powers." ^_^
They are almost certainly air rifles/pellet guns (either term would more accurately represent the objects), while the term bb gun is used interchangeably in some places at times it's an important to keep the distinction between those and smoothbore bb guns in mind. It was an enjoyable little video though, makes me wonder what other weird random bits he has floating around his house that could make for good lecture materials.
I would really love to work as assistant to this man. He is interest in chemistry history, demonstrations, crucial experiments as I am. Very rare in modern days.
This was very nicely done...Its a great example for me as a teacher of High School Chemistry! I just felt as though I received a nicely packaged present. So tidy and classically to the point. Thank You.
I love Dr Szydlo! I can see Dr Szydlo and Marty McFly traveling Back to the Future, or, Dr Szydlo admonishing 007 about not wrecking the DB6. Szydlo = Q.
This guy is fun to watch. And he talks in such detail about all his actions, that you could even follow along if he were on the radio and not be the least bit confused.
Excellent lecture. The more we can make energy dense batteries, while maintaining weight, the closer we are to electric planes for actual transport and not just for toys.
As always Mr Szydlo is a pleasure to listern too, always learn something even at my age,...also just want to say thanks, Andrew, for inspiring my kids years ago, and my youngest was so inspired he;s currently doing A levels, Phyics, mathmatics and chemistry.. and well on his way for an A* in all subjects......if theres ever a Nobel prize for teaching contribution then I vote Mr Szydlo as 1st place...now where did i leave that plasmatronic battery i made last week...???
Don't forget the teenage girl who saw this and wrote one of the greatest early science fiction stories. That story sometimes known as "The Modern Prometheus" but is best known simply as "Frankenstein"
Well... she actually wrote letters to a friend. And Frankenstein was the result of the correspondence. It was a contest between the two. We can tell who won.
Big fan of Andrew and his work! Great style of teaching and personality 😁 Great minds do think alike!! I hope he’s still with us for the next year or so because all the answers of science are about to be answered. Would be a shame if his lifetime of curiosity didn’t get to find what it all leads to and what everything is actually all about. I think he’d have the right reaction, after being amazed at how simple the answers are to all the really big questions, he’d have a proper laugh 😂
Thank you so much Prof. Szidlo! I very much appreciate all your lectures and always find them amazing! I enjoyed every second of it, indeed! Ps: 30 fine smackers! What a deal! ;D
Interesting lecture, could someone clarify the reason for the requirement of the correct polarity for lighting the light bulb. Seeing as the light bulb is purely a resistor load surely it should work in either polarity?
This is how Chemistry teachers should be. I had one with a similar enthusiasm at grammar school. He died in his 90's, but kept in touch with many of his students right through his life. Some of them are now Chemistry teachers. His lessons were memorable, and that's one secret of a good teacher. Thanks for keeping the tradition alive, Mr. Szydlo!
14: 00 why all solution is different ? I mean What if all solution will exactly same ? Or What if all solution will same (like xso4, or xcl , x nitrate ?
Of all the chemical presentations I’ve seen on the Royal Institution Channel, Anything Andrew Presents is very concise well verbalized and exciting. He should Teach if he doesn’t already.
Outstanding, absolutely bloody brilliant presentation Sir, in deed epic lectures you give us i can imagine people watching them in the future as a part of the greatest story ever told.
This videos audio was better than last video :-) did not need as much tuning, still had to adjust equalizer a bit but no big deal. I look forward to the chemistry of sound at a future date ;-)
@Terry White: If you think of a molar solution as the 'density' or 'concentration' of the /individual/ molecules you're trying to measure (eg parts per million (ppm) in a gas or liquid) it' should help you understand.. at least that's how I envisioned it in school..
Thank you very much Szydlo and Oscar. Entertaining and educational. I never really undestood the various levels of reactivity at college. But now I think I do :-)
Watch closely... He bypassed the main lug on the solenoid, such that the result was that the starter spun up without acttvating the solenoid. Had he energized the other, main, lug on it, this would have, accordingly, projected the drive gear forward, as well.
The bulb itself wouldn't be, seemd incandescent to me after it turned off you could see the filament glowing for a bit longer (LED contraptions will look different from this, even with afterglow it wouldn't be that filament wire shape). So I guess someone must've snuck in a diode somewhere into the circuit, as for why someone would do that I can only guess. It might be because the metal holder that the bulb sits in is referenced to what is meant to be the negative connection. If that's the case and there wasn't a diode restricting then maybe something like the following could occur: metal frame gets referenced to positive, you're working on a vehicle which uses the body as a common ground and you source your power from the same battery, the light holder touches any random bit of the body and results in a short circuit.
38:20 I like how he's touching the metal casing of the starter that has the + clamp connected with his left index finger and touches the metal of the clamp of the opposite polarity in his right hand XD
A classic trick for any science tutor (typically used in medical demos); however 12V is rarely enough PD to transfer thru dry skin (hence the 'tongue tingle test' used for checking some domestic electrical cells). 'Volts jolts; amps stamps!': it only takes ~5mA to stop a heart IIRC.. but 'fortunately' this is usually mitigated by the amount of energy dissipated by the current travelling that way (at the expense of boiling/burning off some intervening materials such as blood etc)
@@blueharley2 If you've ever seen someone jump start a car by connecting a full battery to a dead one with jumper cables, you will realize that a car battery will most definitely spark and weld metal because it will put out a huge number of Amperes, even at 12 volt.
if it's rechargeable, it's not a battery it's an accumulator... and the starter has an issue because the solenoid is supposed to push the gear in front of the flywheel before it turns...
Yet another treat from Andrew Szydlo and the RI. I'm loving these special at home presentations from the man himself.
I'm a simple man, I see Professor Szydlo, I click!
This is probably the biggest upside to quarantine. Having regular uploads of Andrew! I just love him! I’d watch him talk about watching paint dry to be honest!
"I had no silver nitrate at home so I made this solution by dissolving a florin" What a god of a gamer.
When learning science, it's so much richer to also cover the history. Love this guy!
Just found this man on RUclips couple days ago and been watching his lectures since then,
I've got to say, I've turned away from several other "at home video's" but Andrew makes a good show, good science, very nice electro-chemistry, very fine home made battery, and plenty of flames and such.

@@robinbrowne5419 ok Thank you..✌😋
If only US lecture classes was as interesting as yours. All would not be lost and boring.
Congratulations, you made me watch the whole thing. Well presented. Thanks for sharing.👍⚡⚡⚡👍
What a wonderful teacher.
This gentleman is always amazing...thanks

love you m8, keep going. You are giving real value to the community
2.5 Minutes into the video & I picked up the "Chemical History of the Candle" on my kindle! Thanks!
florins, bb guns, halfords, volvo starters and 30 smackers, hopefully they are on the test, the rest i forgot.
They are almost certainly air rifles/pellet guns (either term would more accurately represent the objects), while the term bb gun is used interchangeably in some places at times it's an important to keep the distinction between those and smoothbore bb guns in mind.
It was an enjoyable little video though, makes me wonder what other weird random bits he has floating around his house that could make for good lecture materials.
Thank you Dr. Szydlo and Oscar for these videos!!! We need things that are positive and fun these days.
feeling completely inadequate when every time Dr Szydlo says “you might know this” and I have no idea. Great video though.
He also pronounces italian names very well!
John Goodenough?
Thank you very much for your presentation. It was both, entertaining and instructive.
Physics and Chemistry is something that I learned and still learning I have to retake these courses due to how difficult it was the first time around
Great guy. All professors should be like him
Thank you, dear Doctor.
Always a pleasure.

Dude is back!!
Fantastic!!! What a lovely man. I wish he had been my chemistry teacher at school as I may have paid more attention. Please keep doing these.
You, my good sir are an exceptional educator! Thank you, and please produce as much as possible.
I love Dr Szydlo! I can see Dr Szydlo and Marty McFly traveling Back to the Future, or, Dr Szydlo admonishing 007 about not wrecking the DB6. Szydlo = Q.

Love listening to this gentleman
I love watching Andrew. He's a fire lover like me.
I think it’s safe to say that Mr. Syzdlo here is a SUPER FAN of Micheal Farraday.
30 smackers!! he's pleased with that!! love it! great stuff....
You would never know that he speaks fluent Polish as his Mother tongue, if it were not for his name. Great character!
Highly instructional lecture, delivered with true enthusiasm on a hot practical topic! Thank you so much Dr Szydlo.
There are not so many people who can talk about already known things in so interesting way.
What a wonderful way to pass an hour!
Thank you Andrew, Oscar, and RI.
I just want to sit down in the Shire with this wonderful chap and discuss the finer exuberance of ellipsoids .
Excellent lecture. The more we can make energy dense batteries, while maintaining weight, the closer we are to electric planes for actual transport and not just for toys.
Absolutely delightful :) Thank you for a wonderful talk and great demonstrations! I never realized how simple a lead acid battery could be
Awesome , just awesome !
Thanks for the great videos with Andrew 👌👌
Thank you Professor Szydlo for these videos!
Personally, almost every time he says "You of course know this" or something similar, I prepare myself to learn something I don't know.
Thank you for the lecture Andrew and Oscar ,indeed very interesting to get the basics of dc voltage. Take Care and many thanks .Mac
Very interesting video! Thank you very much.

I just love Szydlo's manic videos. I was convinced at least till 17:37 or about, someone had bolted his shoes to the floor.
Agreed, Michael Faraday was the best Experimenal Science Teacher. IMO
Big fan of Andrew and his work! Great style of teaching and personality 😁 Great minds do think alike!!

Thank you so much Prof. Szidlo! I very much appreciate all your lectures and always find them amazing! I enjoyed every second of it, indeed!
Ps: 30 fine smackers! What a deal! ;D
I love his humility and kindness and his astonishing narrative! I couldn't skip a second on any of his vids!
Better batteries would be sweet!
And of course, always a pleasure watching Mr. Szydlo :)
Interesting lecture, could someone clarify the reason for the requirement of the correct polarity for lighting the light bulb. Seeing as the light bulb is purely a resistor load surely it should work in either polarity?
LEDs and a few other types of 12 V bulbs used in cars are polarity-sensitive.
I love all of szydlos vids esp fire & wood x
Indeed great minds think alike!

I always enjoy videos because of the clarity of your explanation
14: 00 why all solution is different ?
I mean
What if all solution will exactly same ?
Or
What if all solution will same (like xso4, or xcl , x nitrate ?

His day job is high school physics teacher in a North London school. 🙂
I’m glad to hear that . It means he’s making our future minds brighter and the future will be in good hands..Brilliant as you all say!
It was wonderful! Thank you so much Dr. Szydlo, I wish you good health!
Gotta watch this more than once. Please sell a translation of that book!
So how would you recharge your makeshift battery back to 12 volts?
Outstanding, absolutely bloody brilliant presentation Sir, in deed epic lectures you give us i can imagine people watching them in the future as a part of the greatest story ever told.

Thank you very much Szydlo and Oscar. Entertaining and educational. I never really undestood the various levels of reactivity at college. But now I think I do :-)
Well, his multimeter shares two things with mine, same model and both need a new battery, ironic given the topic in hand... :P
Nice information
M loving it..... The way of explanation is a very nice,thank you sir....
Does the solenoid on that starter work? The gear is supposed to slide forward on the shaft and rotate.
we don't know if the solenoid is bad.. because he 'jumped' over it (jump start....)
Watch closely... He bypassed the main lug on the solenoid, such that the result was that the starter spun up without acttvating the solenoid. Had he energized the other, main, lug on it, this would have, accordingly, projected the drive gear forward, as well.
Fantastic as usual. Keep up the good work
I study alchemy, science, human history and religion. I'm a new subscriber.
For 30 notes, that starter motor it's a steel. Like the experiment with the history behind it, thank you.
Wait, was that one sentence? 🤨 It's like one-shot movies, you don't notice until at least half-way through.
Yes

i wonder what prepartion Salt solution was , A B or H ??
Why would a conventional light bulb be polarity sensitive ?????
