Lol 🤣 who learns these things in elementary school and High schools are for enjoying yourself and studying for college/university rather then remembering these practicals.
@Tsubasa Akamori haha it was the same for me (I was in high school in the early 2000s), but we didn't have TheXvid or tiktok to offset the limitations. It's great that these platforms exist now 😊
This is the same science behind flashback arrestors when using an acetylene torch, the mesh in the arrestor prevents the fire from traveling backwards down the torch into the gas cylinder
@Additional Audition I’m having deja vu from your comment… It was an odd dream when I had it and even an odder thing that I remembered it, but thank you for educating me once again.
@Goat Sinker it doesn't have to burn far into line to melt the line creating essentially a fire hose of well fire. The lines themselves are just composite and can take some heat, but burning gass from blow back. However it's truly dangerous in more industrial applications using larger volumes. Thank god for arestors
@Goat Sinker thanks for explaining the science behind it better, I'm a highschooler with just a basic-enough understanding of what I'm doing when it comes to my torch haha
@docarii You're right. Oxygen can not burn by itself, neither can acetylene, or any other fuel. In a flashback situation the oxygen and fuel mix inside the supply line due to a drop in pressure at the feed source. Apparently this can happen when the torch is clogged and the clog is removed. At that instant it could happen that the oxygen and fuel mix in the supply line due to a momentary reverse flow. But yes, i have a hard time imagining that scenario.
Very interesting So what happens is that the metal mesh reduces the amount of heat below the flash point of the substance, therefore preventing combustion
This is also why engines on boats ( mostly gasoline / petrol engines) will have flame arresters to prevent explosions from accumulated fumes. Always ventilate and run your engine space fans before you start your engine especially after refueling. Flame arresters can only do so much.
I remember the old lamp that's used in coal mine to detect gas without blowing everything up. I think it's the video by Brady from objectivity. It's called safety lamp invented by humphry Davy
This was how gas detector in mines used to work. They had a flame encased in metal mesh. When the flame started to go crazy in side the metal mesh. you know there is gas in the air and time to leave.(the mesh prevent the flame from igniting all the gas in the tunnel).
With the exact background with the white/gray shade, it looks like any sort of black magic could go on and this guy could explain how each atom moves and why
You can not only contain a small explosion, you can do that with big explosions aswell. It's called a flame arrester and is used in industrial plants to contain explosions within a pipe and stop the propagation into vessels.
I think water heaters have a similar filter. I'm a plumber and it used to be a code to build W/H's onto a stand off the ground so fumes couldn't ignite from the pilot. Now they use a filter similar
This makes me wonder if you can put out a gas fire with a metal spatula type object to separate the fire from where the gas is coming from. Bigger object than a spatula for a bigger fire obviously. Wondering if something like that could put out those giant gas fires that have been burning for decades.
As a lifelong tinkering madman, its not loten that I'm caught off guard by something in the mechanical/science/physical realm but dammit, good job, Sir.
I remember seeing on TV years ago this is why sailors onboard battle ships wear gauze balaclavas, as it prevents flash burns from the gun muzzle flashes.
I remember the video which this short was made of and someone commenting they wanted to see what the flame would look like without the mesh (control experiment). Cool short regardless.
So assuming the actual shock away from the explosion does it break or blow apart the metal mesh, you could actually contain any explosion with a strong enough piece of metal mesh, right?
Probably depends what's exploding, like if there's shrapnel or bits and pieces of stuff. Also, if the heat is moving faster or slower than the metal's conducting away of heat. But a good conductor will conduct away heat super fast so don't know if the spread is heat can outpace it, even in an explosion.
I read a cultivator story where the MC avoided being pulverised by the crazy powerful divine punishment lightnings during his enlightenments by encasing himself inside an assembly of metal cage and rods. Granted this isn't about fire or heat but electricity, but I guess it works almost the same way?
This is how spark arrestors work in oxygen/acetylene gas lines, they're made of thousands of sintered metal balls that creates a metallic sponge, it's next to impossible to get a flame to run past them.
Wow. This is useful. Didn't know that metal net could contained explosion and stop propagate the fire. Before this that I knew is it only useful to stop microwave like Faraday cage.
Holy shit I always wondered why my blues sometimes catch on fire when I’m smoking em but I’m not even close to the edge of the foil. Nice now I know thank you.
This man makes me think, "what if science is magic, and we are all being introduced to magic without realizing it?" Religious people know that magic is a work of the devil.
I remember filling my fist with fumes from my lighter, then lighting it, and lighting a cigarette with the flame coming out of my fist. I quit smoking years and years ago so I haven't done it in awhile.
Just want to know why is this so dangerous to try? Isn't this the same thing lighting a torch with or without the metal strainer? I am seriously interested in knowing thank you
Science & Technology
"Please don't do this it's still very dangerous."
"See I can put my finger"
Lol I came here to say that
Thank you so much for quoting the video you are the future
@j f what if the mesh fails then boom the flame is all the way down to the torch
This is basically action labs’ philosophy hey! Haha
@Name cause some kids try it but the problem is they do it wrong and getting burned and then end up blaming him for their own mistake.
fire: you took everything from me!
metal strainer: i don't even know who you are!
Lol i get it
Everyone uses this meme, but if you don't understand who wins in the exchange of this meme, in this case fire...
You will.
I understood that reference.
@Marino Hernandez there are millions of spam accounts though, its kinda sad😢
@Godwin Kodoe keep reporting any further spam, if enough of us do then TheXvid probably treats it as more urgent to investigate 🔎 🤔
To be an elementary or high school science student in this age must be amazing, having all this fun and engaging information at your fingertips.
Lol 🤣 who learns these things in elementary school and High schools are for enjoying yourself and studying for college/university rather then remembering these practicals.
@Joshua obaga that's true! At least we have some very fun science videos online, so that does help in making science more fun to learn!
@Tsubasa Akamori haha it was the same for me (I was in high school in the early 2000s), but we didn't have TheXvid or tiktok to offset the limitations. It's great that these platforms exist now 😊
Oh no, the most we do in our labs is just titration and salt tests lolol the education system is fucked
This is the same science behind flashback arrestors when using an acetylene torch, the mesh in the arrestor prevents the fire from traveling backwards down the torch into the gas cylinder

@docarii also, the torch pipe is made of metal too which conducts all/any heat from the flame
That’s why high proof alcohol has these arrestors on their bottles.
Oh I thought it was so I could make it a candle
@T0l3D0 419 r/woosh
@Killer Queen No you weren't. Good try though.
Oh! And I guess why funnels for petrol(gas) have mesh at the top of the conical section too?!
@T0l3D0 419 I get the joke , I was taking it literally to make my OWN joke
Okay, but can you take the fire from heat?
Very interesting
So what happens is that the metal mesh reduces the amount of heat below the flash point of the substance, therefore preventing combustion
No actually. This guy is wrong very often. In this case, look up "quenching diameter".
@ambi_cc nah, he was saying about medal strainers, whatever they are. 🤷♂️
Good band name
No shit Sherlock that’s exactly what he said
“You can even contain a small explosion.” Whole room explodes.
@EvilAlatreon963 OH NOOOOOOOOOOOO
Good thing I live in the CAGE NEIGHBOURHOOD!
The house fire is CONTAINED hahahahahahaha the other houses are fine 💪🏻
@Haydan O'C You think the can get away smooth like that? Jokes on you, the rest of the house is on fire
*whole room explodes*
But NOT the rest of the house 😜👉🏻👉🏻
"oh f***!!!! It was supposed to be on the OTHER side on the strainer!!!! Man my wife's gunna be piiiiiiiiisssssssssseedd!!!!"
I read the title and instantly in my head I can just hear z's voice 😂
"Heat from fire, fire from heat"
SAME LMAO
Ayyy!
Same lol
I was gonna say-
@Alagon had to look for it but i trusted it to be here
Heat from fire, fire from heat.
lmao like half the people here are from that (me too) and i live for it
Most torches actually use this along with other things, and have a metal mesh towards the tip to stop the flame from continuing into the tank.
This is real neat. Never thought about a metal mess stopping the fire from going down towards the source of propane.
Heat from fire, fire from heat
(Those who know, know)
(i know)
heat from fire, fire from heat
everybody really here for that and honestly i live for it (i’m here too)
This is also why engines on boats ( mostly gasoline / petrol engines) will have flame arresters to prevent explosions from accumulated fumes. Always ventilate and run your engine space fans before you start your engine especially after refueling. Flame arresters can only do so much.
Fire from heat.
I remember the old lamp that's used in coal mine to detect gas without blowing everything up. I think it's the video by Brady from objectivity. It's called safety lamp invented by humphry Davy
I love your shorts so much and am always waiting for the next one. Thanks for the awesome content!
This was how gas detector in mines used to work.
They had a flame encased in metal mesh.
When the flame started to go crazy in side the metal mesh. you know there is gas in the air and time to leave.(the mesh prevent the flame from igniting all the gas in the tunnel).
I really enjoy these videos but when you add a real life practical use with it (miner safety lamp) , it takes it to another level.
With the exact background with the white/gray shade, it looks like any sort of black magic could go on and this guy could explain how each atom moves and why
Dude I was really confused about that for years. never thought about the heat conductivity .thank you so much. Lol
Heat from fire, fire from heat. If you know you know 🏳️⚧
🏳️⚧️
exactly what i thought of lol
The same technology is used in flame arrestors in a pipe line for large resevoirs to prevent fire from spreading to them.
You can not only contain a small explosion, you can do that with big explosions aswell. It's called a flame arrester and is used in industrial plants to contain explosions within a pipe and stop the propagation into vessels.
The strainer thing is why they put mesh on some blowtorches so the fire doesn't go down into the valve and propane tank
Goodness this is terrifying and amazing to watch. Keep up the good work!
Always learning random cool stuff like that, man I wish you would have been a teacher in my school !
Imagine this guy being your science teacher
I love these clips! I have to figure out if I can use this for combustible dusts.
I think water heaters have a similar filter. I'm a plumber and it used to be a code to build W/H's onto a stand off the ground so fumes couldn't ignite from the pilot. Now they use a filter similar
I've seen this with paint cans since I was a kid
This strainer thing seems useful
Im so glad scientists have created Bluetooth Fire
heat from fire, fire from heat
heat from fire, fire from heat
I got to hand it to you man you put out a LOT of quality content
Fire: I am nothing without my heat, this man took it from me.
Water: First time ?
Could this be used on smaller houses by firefighters? Perhaps to stop the fire from spreading
This makes me wonder if you can put out a gas fire with a metal spatula type object to separate the fire from where the gas is coming from. Bigger object than a spatula for a bigger fire obviously.
Wondering if something like that could put out those giant gas fires that have been burning for decades.
Isn't it interesting that a metal cage works both for containing flame, as well as electric fields? Rememberthe faraday cage? Just neat.
We all know you can light a propane tank with a spark
Me who didn't know that: 🙃
Fire from heat 😌
As a lifelong tinkering madman, its not loten that I'm caught off guard by something in the mechanical/science/physical realm but dammit, good job, Sir.
This man is a real wizard
These are more commonly know as “flame arrestors” , “detonation arrestors”, and “deflagration arrestors”
Flame arrestor is a good band name
I remember seeing on TV years ago this is why sailors onboard battle ships wear gauze balaclavas, as it prevents flash burns from the gun muzzle flashes.
Experiments like this really help you see the fact that what we call fire is just hot gas.
I remember the video which this short was made of and someone commenting they wanted to see what the flame would look like without the mesh (control experiment). Cool short regardless.
Airboxes often have a metal mesh behind the carburetors to stop backfires from burning into the air box
The strainer is also use for flame arrestor in marine engines.
If I wasn't scared of fire, I would've loved to try that tiny explosion
damn thats pretty crazy.
I have that exact strainer
So assuming the actual shock away from the explosion does it break or blow apart the metal mesh, you could actually contain any explosion with a strong enough piece of metal mesh, right?
Probably depends what's exploding, like if there's shrapnel or bits and pieces of stuff. Also, if the heat is moving faster or slower than the metal's conducting away of heat. But a good conductor will conduct away heat super fast so don't know if the spread is heat can outpace it, even in an explosion.
Your ideas are really genius💡
Never knew that about the lamp. Awesome!
I read a cultivator story where the MC avoided being pulverised by the crazy powerful divine punishment lightnings during his enlightenments by encasing himself inside an assembly of metal cage and rods. Granted this isn't about fire or heat but electricity, but I guess it works almost the same way?
Would this work large scale? If you made a large mesh cage and made an explosion outside of the cage would you be safe in it?
i can only imagine how nervous you must have been when you put your finger between the torch and fire
This is hands down the greatest TheXvid channel of all time.
Heat from fire, fire from heat ;)
Every episode is like a tidbit of science knowledge
They use the same idea on boat engines to prevent fires and explosions.
Giant strainer for forest fires, perfect intervention
This is how spark arrestors work in oxygen/acetylene gas lines, they're made of thousands of sintered metal balls that creates a metallic sponge, it's next to impossible to get a flame to run past them.
Why is it so dangerous? Great, now I feel like trying it!
This is likely the same principle most gas stovetops work on
As Usual You Are the Best 😉 Experiments Bringer To Us👍
“We all know you can light a propane torch with a spark”
Me: 👀
Always quality content
It's how those little gas heaters for fish houses work, it's really neat
Sounds really cool man 👍🏻
Wow. This is useful. Didn't know that metal net could contained explosion and stop propagate the fire. Before this that I knew is it only useful to stop microwave like Faraday cage.
Sometimes the filters on top of carburators are called flame arrestors
Holy shit I always wondered why my blues sometimes catch on fire when I’m smoking em but I’m not even close to the edge of the foil. Nice now I know thank you.
Interesting. Does it work inverted?
This is amazing!
Sick, so it’s like an opposite faraday cage effect in a way haha, except, for fire 😄
Fire from heat, heat from fire. If you know you know
Saw this in my water heater. I thing the red glowing mesh even helps combustion.
This man makes me think, "what if science is magic, and we are all being introduced to magic without realizing it?" Religious people know that magic is a work of the devil.
"Please don't try this, it's extremely dangerous still."
Me: no, I don't think I will
So that's the science behind a flame arrestor, very cool!
What to take away from this: a room catches fire, just toss a really big strainer over it
Very similar to putting steel wool into a DIY blowtorch
This is fascinating. What's that lamp at the end?
wow didn't even know about this more and more knowledge about science from your channel 😄
I'm a fan forever. Love this channel.
So, if i cover my self with mesh and there is explosion outside ,will it save me from burning.🤔
I remember filling my fist with fumes from my lighter, then lighting it, and lighting a cigarette with the flame coming out of my fist. I quit smoking years and years ago so I haven't done it in awhile.
00:31 - I love how he used his left hand for risk
Wow, that's look awesome!
I had to use stainless screen on my forge because the heat was destroying the metal pipes 😂
"This is extremely dangerous" *proceeds to finger a stream of ignited gas from the source lol*
Like a spark arrestor on a fourwheeler to keep backfire from causing a forest fire.
Just want to know why is this so dangerous to try? Isn't this the same thing lighting a torch with or without the metal strainer? I am seriously interested in knowing thank you
"It's not even hot"
Why should it be hot? Classic cpt obvious moment 🤣
Finally, I understand why the CDA used that little bowl.
Oooh! It reminds me of when in Monsters Inc. to explode the sock they put a metal dome over it
You took the words right out of my mouth when you mentioned the Davey lamp. Great short. 👍
This was awesome.
