Good demo and appreciate the science and you trying to keep students interested. Fire and hydrogen are a dangerous combination considering a hydrogen plant blowup last year 2020 in NC blowing out the windows in 60 houses and rendering a house uninhabitable. Be Safe!
Thank you! I completely agree with you about the dangers of Hydrogen and will continue to remind people that they should not 'play' with hydrogen - ever!
Beal's Science | Hydrogen is a quick pop explosion. I understand the Hindenberg skin burned however, where was the pop? Or why no pop with massive expansion of gases?
I am, by no means, an expert on the Hindenburg disaster but I will share some experience from doing many reactions with Hydrogen. -When combusting, hydrogen actually reacts very quickly but not as quickly as it may seem. Hydrogen, as you know, must have oxygen present to combust so as the reaction starts to happen, Oxygen from the surrounding air must be present to keep the reaction going (remember we are reacting H2 with O2 to make H2O). -When I want to have a quick hydrogen reaction in a balloon, I fill the balloon about 2/3 full of Hydrogen, then blow up the remainder of the space with my own breath (which contains oxygen). This reaction is significantly faster and significantly louder. This is because there is oxygen intermixed with the hydrogen - so everything can react more quickly (and produce a louder sound). -When I am doing BIG science shows in a LARGE auditorium or gymnasium, I bring along my hydrogen tank AND my oxygen tank. I pump the balloon 2/3 full with H2 and 1/3 O2. This reaction is SO fast and SO loud that I actually had two 1st graders pee their pants (I probably should have given a more clear warning I guess...) -So, why wasn't the Hindenburg a faster and louder explosion? The only oxygen present was oxygen in the air and a lot would be needed to combust all that hydrogen - so it took a while for the reaction (FIRE) to completely consume the airship. Does that help?
Very easy, because it wasn't in a contained pressurised space so to speak. When the skin of the hindenberg started to burn it made a hole, then bigger and bigger, and the hydrogen could escape through the top. That's why on the footage you can see the flames shooting upwards, where the momentum of the flame went.
With the hydrogen bubble one, we kind of did something like that in school except we held a lit match above a bowl of water while hydrogen bubbles were surfacing from underneath. But the outcome wasn't mild pops, this match went off with a proper bang, like people's ears were ringing and neighboring classrooms actually came to investigate what happened. What would the reason be for such a different outcome?
@@BealsScience No so we were learning about catalysts and the chemicals we used, if I recall correctly was iron and hydrochloric acid (can't remember precisely, this was about 10 years ago, but those two come to mind) produced the hydrogen gas which was directed into the bowl of water by a glass pipe. But working off your explanation, is it possible that as the bubble popped the hydrogen released mixed with the oxygen in the air between the bowl and the match before igniting?
@@xdemon5015 Oh yes, the classic replacement reaction to produce hydrogen gas! We do several experiments using metals and acids to produce hydrogen gas. In fact, I've got a video on my TH-cam showing how to make mini rockets from hydrogen and oxygen gas produced in this way! th-cam.com/video/V6VPJA2jg7s/w-d-xo.html
Hello, Wonderful demonstrations. I've heard of the danger of fire catching and traveling all the way to a gas cylinder and causing it to explode. How is that danger of the hydrogen exploding your gas tank avoided? Is there some kind of spark resistor? Hope to hear your method to prevent that. Thank you.
I made the following website for teachers so they could learn how to do these experiments with their students. Share with your teacher! www.bealsscience.com
Could you use hydrogen made from muriatic acid and aluminum foil? I.E. put them in a bottle, mix, then attach balloon to catch gas... Obviously don't light this close to yourself. But would this work? If so, I would like a video. Please respond, I'm very interested...I want to know if it would be pure enough to do your balloon experiment.
@@BealsScience Thank you very much for replying in such a timely manner, it is greatly appreciated! :) My idea is to do as follows- First, Get either a VERY large balloon or maybe some type of large bag (trash bag size is the goal) with a sealable opening and fill with hydrogen made from acid and foil. Then second, soak a string ( probably cotton) that's about 10 feet long in gasoline. Third, attach soaked string to bottom/side of balloon or bag. Fourth, let balloon/bag rise into air until it is as high as possible while still holding string. And Finally, light string and let it float away and BOOM when 🔥 reaches the balloon! I will be doing this in a wide open field with nothing around to catch fire or damage. What do you think? I call it "The Hindenburg Balloon"!
I think you are exploding pure hydrogen wich just creates a flame as it can't immediatly bond with oxigen molecules to form H2O in the exothermic explosive reaction. the best ratio is 67% hydrogen and 33% oxygen
Both have pros and cons. Methane stores a lot of energy that can be slowly released making it a good fuel. However it is a greenhouse gas and so is the CO2 it produces. Hydrogen releases energy quickly so it can be dangerous to store in large quantities (explosions). But it can be made from water and it’s only product is water. So, my vote is Hydrogen!
It would be a big boom, that’s for sure! Likely it would destroy the room and a fireball would progress through the house. It would probably be more devastating if the gas were all released into a larger space because it would be easier for the hydrogen to interact with oxygen so the reaction could continue at a fast pace (faster means bigger boom!) Let’s home I never actually find out!!
Great question! I will try to answer as best I can without being able to write out the needed symbols (the comment sections doesn't have symbols enabled). Hydrogen has an enthalpy of combustion of -286 Kilojoules per mole (kJ/mol) [this is negative because it releases energy] All gases contain 1 mol / 22.4 liters of gas. Using dimensional analysis: -286kJ/mol * 1mol/22.4L = 12.77 kJ/L Is that what you are looking for? I am making the assumption you are looking at Hydrogen by itself and not the diatomic hydrogen?
If your school gave you this as a research question. They need to be taken out at dawn and shot. First you need to know the pressure and temperature of this litre. Then you need to know what you are combusting it with... and so on. The rest is already nicely answered.
How do you store hydrogen in that cylinder? And may I know what the cylinder is made up of, cos I've been told that it is tough to store hydrogen in Gaseous state
And that's where you wrong kiddo. Sorry for that but a hydrogen bomb or also called thermonuclear bomb works on the principle of nuclear fusion in combination with nuclear fission and really has not much to do with *regular* hydrogen (H), only its isotopes deuterium (²H) and tritium (³H)
I agree. I used the best camera I had at the time. It took al long time to save up but I recently got one that will shoot 120fps in 1080. So, one day I may revisit these experiments and capture them with a better camera.
you will get subs soon bro....dont lose hope
Thanks!
I will keep pushing forward!
This is what your high school physics teacher does at 3:10pm
@The King of Nature big brain comment😂😂💀
The balloon explosion will be much louder if you fill it with a hydrogen-oxygen mixture in a perfect stoicheometric ratio. That will make a loud BANG.
It makes a huge bang!!

This was amazing and I love hydrogen too
It is my favorite! I keep a big tank in my store room at school so students can "feel" combustion on days where we need a big boom!
2:24 Once you pop, you can't stop...

Did you use electrolysis to make the gas? If so, the bubbles were probably a mix of hydrogen and oxygen and they are very loud when they ignite!

I don’t ever react hydrogen directly from the container or valve.
I either bubble it or put it into balloons to combust it.
This video is lit
Thanks!!
Nice cool scientist
Thank you!
Too underated ngl
the potato chips sounds great!!! right?

Why dont you do a hydrogen/oxygen mixture?
What music did you use I love this!!!
-waiting for +Beals Science to get tired of me popping up every time he turns around-

You need a better slow mo camera. But nice video
I agree! Hopefully some day I can get something with High Def (4K) at 120fps or better! But for now, I am stuck with high res at slow speeds...
Am I the only one wondering if you can eat the Pringle?
You can definitely eat the Pringle’s!
In fact, I do this demo on the first day of school and all the students get to have “toasted” Pringles!
Is water created in this reaction?
Yes. Water is the product of this reaction.
Sure. Water is the by-product. But unnoticeable for the amount of hydrogen reacted.

amazinggggg
which is better for vehicle fuel, methane or hydrogen

So, my vote is Hydrogen!
Rather not have it in my home tbh
How big would the explotion be if that gas tank of yours wiuld explode? Is it like goodbye room or house or half of the neigbourhood
It would be a big boom, that’s for sure!
Likely it would destroy the room and a fireball would progress through the house. It would probably be more devastating if the gas were all released into a larger space because it would be easier for the hydrogen to interact with oxygen so the reaction could continue at a fast pace (faster means bigger boom!)

doesnt this mean, you technically could use hydrogen in a combustion engine?
Yes!
How do you store hydrogen in that cylinder? And may I know what the cylinder is made up of, cos I've been told that it is tough to store hydrogen in Gaseous state
H2 is highly corrosive. Storing it for short time can be the solution.
Try hho 😁
FUS RO DAH!!!!!!!!!!!!
+sednodar dragons beware!
Beals Science they are already gone they were too intimidated by your skillz
sednodar ha! Way too kind! My skillz could use some refining...
👌
You should probably make a disclaimer
You are crazy
😆
@@BealsScience but i liked you bro
wont the hydrogen saturate the chips and make them unsafe for eating ?
No. The hydrogen is converted to water vapor in the reaction.
@@BealsScience
Ok cool, thanks. Good vid btw
Thank you!
That happened to my hand in science class
Squeaky pop turned into loud boom that could be heard in most classes XD
Hydrogen bubbles in your hand? Or a different experiment?
Basically how tsar bomba works
And that's where you wrong kiddo.
