The Professors hair is more Professory than ever today!
I wonder if he uses selenium sulfide shampoo.
StarkRG the professor would never Sully himself with such a product
His hair is perfect just the way it is.
Needs a shearing. :3
4:54 Onwards is like you've been put in some weird torture device while the professor watches you drown, but just before you lose all hope at 5:17 Neil comes and saves you
Pure kino
unbelievable, neil touched the SO4H2 acid!
@Rafta Music The danger relies on concentration.
you should consider making "The Dark Side of the Period Table" I love this drama.. more death and pain please !
I remember that this was a big deal here in Sweden in the 80's and 90's and there used to be planes dumping calcium in the lakes...
let's hope they were dropping calcium hydroxide and not calcium into the lakes. I fear dropping an element such as calcium into large bodies of water would be quite explosive.
I think they were just using powdered limestone.
@RC Buggies yes, sorry bad english. I meant calcium carbonate ofc
Well the germans had calcium cannons in use in their forests for a decade to stop trees from dying.
Hi I have a doubt would the reaction increase the salinity and would that increased salinity cause any damage to the fauna over there ?
For one of my science fair projects in elementary school I (and a friend) tested the effects of acid rain on seed germination by watering bean seeds with a mixture of water and vinegar. We tested 0, 25, 50, 75, and 100% vinegar to water ratio. It was the only science fair project that I worked on that led my friend and I to go onto regionals.
When I was in the 6th grade here in the US (Upstate NY) my science fair project was based on acid rain. My great uncle was a forest ranger in the Adirondack Mountains here in New York and he was one of the first to bring to the public's attention the effects of acid rain on the waterways, wildlife and plant life in the Adirondacks. He was featured on an episode of a children's science show "3-2-1 Contact" in November of 1983.
@Charli Espinoza Me too! I can still sing most of "The Bloodhound Gang" theme song.
At least back then politicians moved to solve the problems of acid rains and the holes in the ozone layer, nowadays often the response from politicians is that climate change is not real and scientists are either lying, exaggerating or don’t have a clue.
Very cool. I'm from the Adirondacks as well.
From RI, was born in 84 and we still got taught about acid rain early on and I remember hearing and seeing it pop up on stuff but of course declined to nothing it seems quickly into the later 90s. I remember me and friend were like "what of it happened here, would the cars melt?" Lol the minds of children.
Siren wails, evacuate immediately
I live in the UK and I remember when I was a child seeing huge billboards made of some sort of indicator paper to highlight acid rain.
7:47 Photo taken by Professor. Wow, Professor knows how to take a nice photo!
Very surprised about the roses in Nottingham, I knew about the smog and acid rain negative effects, but that one took me by surprise.
Brady, do you think the professor would be willing to talk about his life?
This makes me recall visiting Sudbury, Ontario, in Canada many years ago. The environment for many miles around seemed more like some strange planet as everything was blackened by Sulfur dioxide emission from a Nickel ore smelting operation.
That's interesting considering nickel is seperated from the ore by floating it in acid not smelting .
@Mathew Kelly I dont see any reason you couldn't smelt it
No Matthew Kelly it is still smelted. Froth flotation and all that happens at the mill. It then goes to the smelter, then the refinery.
Sudbury isnt a blackened moonscape anymore. A regreening project started in the 80s and has been very successful. When I was a kid the air tasted like sulfur, but now SO2 and other contaminants are captured.
Its a joy to see prof alive and well!
Great experiment - I remember when acid rain was a real problem here in the US. Glad to see things have significantly improved. Somewhat ironic that a pollution problem was helping the Nottingham rose industry.
It was a wonderful and beauty experiment!
Some say that he naturally secretes sulfuric acid from the soles of his feet, and that he hasn't spoken since the Great Potassium Explosion of '48 out of pure shame. All we know is, he's called Neil.
Something tells me this would work better when the water is in its condensation stage in the clouds, more surface area!
Same thing happened in the Northeastern US. Winds picked up the gases from coal plants in the Midwest, dissolving them into the moisture, and then dropping the acid rain into the Adirondacks. Screwed up the pH of the soil and the lakes, killing forests and loads of fish. Thankfully, they've mostly recovered, but it's still an issue.
It's always a great day when periodic vidoes posts a new video.
The calcium sulfate produced by the SO2 flue gas scrubbers on coal power plants is not "just put to landfill" in the US. It is a useful product sold to National Gypsum which uses it to produce things like drywall boards for construction. This works fine when the process is well controlled and regulated, but they started doing the same thing in China some years ago too, where regulations are lax or nonexistent and they didn't take care to remove the substantial amounts of strontium sulfide in the fly ash which made its way into the synthetic gypsum product. This SrS in drywall boards sold to the US then reacted with humid air in Southern homes producing hydrogen sulfide and carbon disulfide gas which was emitted from the product continuously and caused many health problems and severe corrosion of home electrical wiring and water pipes which are made of copper (copper sulfide) resulting in many millions of dollars worth of damage.
Muonium Wow! Only knew half of that story.
Interesting!
I was happy to see sir Martyn and Neil again! Keep up with videos, we crave more!
Man, ever since i started watching these videos with the Prof i had always wanted to be his student. I love chem and the way he explains things in these videos makes it so effortlessly entertaining and easy to understand. Is like he is explaining things to like first graders, lol.
In a way i do feel like his student by watching these videos.
"... an acidity between lemon juice and battery acid." I don't think anyone in my household really understood how bad it might be until that came up.
Everybody knows the easiest way to get Acid Rain is have a 5th level wizard just cast it
I summon... Niel...!!!
Fantastic stuff! A lovely demonstration of all sorts of things, but I like the ecosystem bit at the end with the roses. You never know what a change is going to do... sometimes until you stop changing it!
Thanks for the video. I remember learning about acid rain in school and it really terrified me. Then I forgot about it because I've never seen acid rain. I'm glad we took steps to fix that problem, few more we gotta deal with though.
Before I saw the (indoors) tag, I dreamed they released acid into the clouds while doing the mad scientist laugh. 😁
Ah, I remember the days when the rain used to make your eyes sting
"...I will take away the pain
When only I remain
To feel the acid rain
..."
I love Neil, He is the guy "Nah screw it I'll try it with ten times the amount" Had a cemestry Teacher like this once, he often blew the glass out of the windows.
Honestly professor, I adore you!
This is the kind of chemical reaction demonstrations that motivate people like me to study chemistry.
I'm from Norway and I remember learning about acid rain in science class in middle school. It was 2007 or 2008 so it wasn't as relevant anymore, but our textbooks were from 1999. It was honestly the only time before now that I've even heard about it.
I love this channel. Professor , try another video talking about acidic rain in known planets, like venus! :D
Loved the very short story about the roses. It just shows even tho one thing can be really bad for certain things -- something entirely different can... literally blossom from it.
would be interesting to see some chemistry involving some uranyl compound.
That’s something I always wanted to see
But also do one with a miniature monument of chalk to show other effects
2nd
How about cabbage water?
We really miss you, Mr. Martin !!! Hope you make more videos ❤
It's "Sir", he was Knighted for his efforts in education and science.
British peerage is a meaningless to the rest of the world. Dont be a douche
@D k Make sure you respond correctly next time so YOU dont look like a douche
I've never been so early for one of these! And about one of my favorite things to learn about as a kid. I love this!
Very powerful demonstration! Good reminder of the danger of burning sulfur bearing coal.
Can we get an update on the Professors work with green chemistry? I am particularly interested in the idea of using super critical CO2 as a solvent. Is there any update on this? What is the current status of green chemistry?
I've been watching these videos for years and I don't think I'll ever be ready for his hair
Hair looking wilder than ever - love it, Professor!
Man, his hair and teaching is AWESOME
Wow! Entertaing and very imformtive as always! Please keep the videos coming!
I remember the acid rain in the Los Angeles, California area, back in the late 70's. It would eat the paint off of cars.
I do love the appearance of Number Sixteen! Bright yellow turning a deep red at melting and with a lovely blue flame.
Nonmetals are the most fabulous elements.
Neil went all the way on this one!
When the video goes to the graphics or the experiment I still see the professor moving his hands
I remember the acid rain issue in the 80s here in Canada, particularly in Ontario... it was on the news and the rain would cause burning in your eyes if you didn't use an umbrella. I've always wondered why that disappeared from the public...
This is one of my favorite channels if not my favorite. I just wish more videos were uploaded

Professor: "I am going to show you this demonstration with this nuclear weapon I inherited from my friend"
s3cr3tpassword - 2020-02-14
His friend is Jeff. the guy with the 10th largest nuclear arsenal in the world.
Guy Boo - 2020-02-15
That would be an amazing April fools day video. They act totally serious for two minutes, fool about with some random equipment from the lab, then “April fools!” and 9 minutes of black to prevent the video length giving it away.
iabervon - 2020-02-15
@Guy Boo They could certainly actually talk about the subject for the usual time with just the demonstration being a joke.
TheNewGuy - 2020-02-16
@Guy Boo I fully agree. They would explain the processes of refining Uranium Ore, and how a nuclear weapon detonates. Then, cut to a field with a case of a nuclear weapon, and say "April Fools!". 10/10 idea.

@invisible boy if it was plutonium they'd take it apart and build a time machine instead!
