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!

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.

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).

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.

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?

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

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.

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.

@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?
