Andrew takes us on a journey to London’s Shepherd’s Bush Market in 1960, exploring the splendid chemistry of potassium permanganate. Along the way, he will explore redox reactions, colour changes and even the “devil’s element”, phosphorus.

Oh gosh, oh golly, are we excited! While we have been away from our building for three months now, our friend, the most wonderful chemistry teacher Andrew Szydlo, has sent us a gift like no other – an entire series of chemistry videos, filmed in his home and exploring concepts such as the chemistry of coins and photography, how a chainsaw works and even how to fix a leaking tap. We're so excited to watch these and to share them with you!
I love his videos
In school it was my favorite thing.) If you make Al-Permanganate powder then you can initiate it with just a couple of wires and about 80-100 V of electricity from capacitor. It's very robust and reliable thing that doing well in very wide range of temperature and works very fast.
When he left the spatula in the solution! Nooo! There goes the nickel coat
The painting fellow was Nic Flamel at heart, bless him
Silly old fool
you cannot buy KMnO4 now in EU as it is a precursor for drugs. U need government permit to get any. I played with it a lot when I was young, it was during the communism, yet we could get it then.
that's a mother of flask!
Didn't I see this same demonstration and story somewhere else??
THE BILION USED TO MEASURE THE POPULATION IS AN AMERICAN BILLION 8 THOUSAND MILLION MY FRIEND YOU ARE A FACTOR OF TEN OFF 8X10^6
I wish I had had a chemistry teacher like him 🙂
Chemistry is explosives, drugs, poisons and unemployment. Stop producing chemists if you are not going to hire them.
Thank you so much for this video series. Love it! Your teaching style is so retro and reminds me of my whacky A Level
lecturer back in the day. Great way to remember “stuff’. This one in particular is Outstanding as I remember writing “Potassium Permanganate” for any substance that I couldn’t identify in my A level Chemistry exam. Happy Days 🙂 Keep up the good work and keep it old skool.
While 8 billion is indeed 8 million million in most of the world, this is not true in English-speaking countries that have adopted the american "short billion" (one thousand million). The population of the Earth is about 7600 million (not 8 000 000 million).
Totally read that as pomegranate
So fantastic, we love us some LORD OF FIREEEE! o/
Andrew Szydlo has given out the best gift in the form of these videos during this time, even cannibalizing his Triumph and holding Oscar hostage in his basement to provide us quality edutainment <3
This man was my Chemistry teacher. He was also ran the photography club, the automobile society, the beekeeping club, and was co-leader of a club called "Operatic society" which was in actual fact a chamber orchestra/fine dining club, where he bought nice cheeses for us to eat and played the viola. Man is a force of nature.
An inspiring teacher – wish they were all like him. I loved his lesson/demo
Around 15:56 he says 8,000,000,000 is "8 million million". Am I confused by something or is it not 8 thousand million?
I didn't know i liked chemistry until i saw this guy. Now i can't stop watching videos about it.
At the one millionth concentration, it's an excellent water purification. Just adding glycerin or glycol will ignite it.
If I had him as my chem professor instead of some grad student, I would have become a chemist!
