I love how much trouble he has with everything
Nonsense! He is a smooth operator ;-)
He is teaching what to do at the same time also what not to do 🙈
He's having trouble putting things into words. Like he's spot on for why the second one was louder but it was quite jumbled
Thanks a lot finally my confusion of whether the hydrogen burns or burns out when it combusts is clear😅🙌
Honestly, I know he knows the subject, but somewhere along the way he lost what he wanted to point out, and just started going to see if he could remember.
I just look into him, Professor Emeritus Irwin Talesnick (the old guy), and he apparently died on 21 November 2020. 😥
He started off as a High School science teacher in the 1960s and then went into teaching science teachers how to teach science at Queens University in Canada.
He was obviously very successful, as shown in the video!
I actually love that shirt, I've always felt the same way!! VERB
*This is giving me some old vibes...*
TRG // The Redstone Guy lol
yes, this man appears to suffer from a rather severe case of the olds.
He doesnt explain that the foggy mist around the cylinder is actually water created from the combustion of the hydrogen gas. However, this may have been useless information to his students so he may have left it out for that reason to save time 8).
hold on, I have a question bro.
does a liquid compound will be vanish, if it's got burn by a fire ?
I mean if let say a vitamin c liquid, got burned, will the smoke still contains with a vitamin c ?
I doubt that. The water would be too hot, and would be produced in extremely little amounts. It’s probably the moisture and humidity in the air cooling rapidly and condensing.
I bet every one of his students knows that
@@ravenskarm6968 bro burning is a chemical reaction and everyone know that after reaction it is not sure that reactants property get/found in product.
@@potatoboy549 no it's actually water
I like the way he teaches
This is a great experiment ...
No it's not. It's completely skewed. While igniting the tube with "pure" H, the gas has but one orifice to escape from and, consequently, interrelate w/ to form sound. When the two tubes are near one another, there are multiple avenues for the gas(es) to move between and even more surfaces to interact w/ and form sound waves. Also, "which one was louder" is not a very scientific (specific) question. Does he mean intensity of dB, SPL, or Hz?
Great sir. Good experiment
THat dudes shirt is awesome. I love to science when I get high.
WRONG! He is teaching grammar wrong!
Science
verb
To do the act of _sciencing._
"John, you've been down here for 18 hours. Please come have dinner with your kids."
"NOT NOW KAREN I'M _SCIENCING."_
@@dylanm.3692 lol
Why don't the space ignite in flames with our spacecraft thrusters if space is mostly packed with Hydrogen gas?
"This video is part of the Best Practices for Teaching Chemistry Video Series."
If I'd be interested any second-best practice for Teaching Chemistry, is there anything around?
Now I know why fart burns...
Nicely explained!
nice
Just for the shirt I give a thumbs up and I love the sound effects but where's the fire?
Hydrogen fire is almost invisible.
Funy how easy it is to separate this from water and how easy this would replace gasoline.
It's not and it's not. :)
@@alexcasillas22 video fake?
@@alexcasillas22 ah ok your just a shill or dont know probably
@@alexcasillas22 it is
This guy is so dangerous! Flame Arrestor: Always use a flame arrestor when working with hydrogen gas and open flames. This device prevents a flame from traveling back into the hydrogen source, which could cause a catastrophic explosion.
Come on dude get it together
But why wasn't water formed?
it pops louder because of the presence of oxygen from air.
💗💗💗
Grt
So this creates water
….. is hydrogen lighter or heavier than air? Density.. end comment!!
Tremblinggg handddssss
I wouldn’t trust this guy around combustible material
lol
Lol
5:35
candles suck, why not use alcohol burner. second one popped louder because hydrogen mixed with air and became explosive?
ledgit no one volenteers
Me coming here after learning about bill gates new yacht me seeing it’s combustible no bill not 2020 maybe 2050 but no
Are you aware that the fuel that makes your car go is also combustible? That's kind of the point of a fuel, in fact it's in the definition. Hydrogen can be just as safe as gasoline when handled correctly. Please dont spread fear around something you may not understand, thank you
its melindas yacht now
His voice reminds me George carlin..
Sun made of three fourt
Hydrogen gas
I'm here from school
I am here from Georgopol
he doesnt know how to use a tealight candle
Science is a verbe!
"science is a verb" ? that's deeply philosophical...
I came here because of raptor 2
People have always said hydrogen isn't flammable without oxygen. That is obviously wrong based on this experiment.
Energy is created when quarks are separated and pure hydrogen without any neutrons is the most vulnerable to getting broken up. What creates the energy is not the hydrogen itself but the field of space around the reaction. Without the field, no energy would exist at all. It is what's known as "zero point energy" and when quarks get separated, the strong force is broken. The only difference is that the strong force is between quarks and the particles that make up the field of space, not gluons. When quarks are separated in a vacuum, it creates an incredible energy because the field of space that causes the force of gravity is able to overcome the strong force and keep the quarks apart indefinitely. This is exactly what a black hole is made of and the only reason they don't emit optically visible light is because they only emit gamma rays. Eventually, black holes cool and create elements on their surfaces and start emitting optically visible light.
Quark Plasma Reactors only use plain hydrogen, not deuterium and tritium. They are the energy fusion is supposed to be.
I believe under normal conditions Hydrogen isn't flammable without the presence of oxygen. There's way better demonstrations with Hydrogen on yt. ... guy fills a large bag with Hydrogen and strikes matches inside the bag . The match lights for a second and goes out after exhausting its own fuel source of oxygen. The Hydrogen didn't ignite/combust . To prove its Hydrogen in bag. He squeezes the bag that has a tube coming out of it and it produces a maroon very translucent flame a few inches long when introduced to a flame ..
Hydrogen absolutely needs oxygen to be flammable .
@@codyramos3200 unless it is separated into quarks. When this happens, the energy that lasts billions of years in space as stars is created. Lightning does it when it destroys atoms in our atmosphere and creates gamma rays. Particle colliders do it as well when they break atoms into quarks and create 9 trillion degree Fahrenheit temperatures.
Bit of a shambles....
Hands way too shaky
He's a Jew, he hes yarmulke on a back side of his head.
That doesn't have anything to do with science
Why do Jews make lovely teachers? :3
Cup your ears, gotcha, you didn’t need to, how interesting huh?
Electric cars are trap for dumb punters. Hydrogen is next fuel in combustion engines.
Isn't he exposing himself and everybody else to a lot of dangerous nitrogen oxide gas from all that combustion of hydrogen gas?
What?
@@cardmaniak2316 of cousre you might be confused see I was looking at a video explaining the difference between using h2 gas in a fuel cell vehicle vs an h2 combustion engine vehicle and they said one downside to the h2 combustion engine vehicle is that it produces harmful nitrogen oxides in the exhaust from the combustion of hydrogen gas. So I was wondering if by this guy combusting hydrogen like that, if he was exposing himself or everyone in the room to dangerous nitrogen oxides.
@@vincenzopromedia very complex i can't understand Im stupid hahahaa
@Frank Martin Okay so I guess temperature has a lot to do with it. ICE Engines do get very hot but I would assume that combustions are very hot in general. So if you simply heated hydrogen without combusting it, would that also cause nitrogen oxides to form? Or is that only under high temp combustion?
@@drdefecation Where would I go to get an expert's opinion?
this guy is incapable of doing any experiment
" this one popped loud "
I'll take your word for it. My ears are only rated for dB. I heard no distinguishable difference from pop and pop.
Science is not a verb! It is a noun! Everyhing else in the experiment was interesting. thank you. For example, I science now. It does not make sense. I science yesterday. Do you see how you are teaching grammar wrong? Yes or No. If you are mad, do not answer!
>Autism speaks
Boi u tryna say science can not be a verb? I science your grammar. Boom
In case it really needs pointing out, the point is that you really understand science by doing!!
John boy you are petty
hold on, I have a question bro.
does a liquid compound will be vanish, if it's got burn by a fire ?
I mean if let say a vitamin c liquid, got burned, will the smoke still contains with a vitamin c ?
