All acetylene cylinders contain a porous honeycomb material called a monolithic mass. They also contain a solvent (acetone) which is absorbed by the porous mass. The acetylene dissolves in the acetone and holds the acetylene in a stable condition. So it doesn't explode from impacts and shocks. If you lay a acetylene bottle on it's side don't use is set it upright so everything mixes back together in a stable state.

Welder here. Rock Crawler gets it. Acetylene is so reactive that it must be dissolved in acetone and held in the honeycomb material to be stable. Acetylene is usually stored at much lower pressures, around 15 PSI in the bottle you see in this video, compared to 2200 PSI for the oxy. I think its the second most reactive gas in the universe, the first being hydrogen, unless someone wants to correct me on that? Also, true what Rock Crawler says about laying the bottle on its side. Manufacturers usually say you should have it upright for 45 minutes before attempting to use it, as the acetone can damage the regulators on your acetylene torch. I have also used an acetylene torch in extremely cold environments, (think -45C or -49F) it is too cold for the the acetylene to evaporate from the acetone and the acetone gets pulled into the torch regardless, producing a useless, dangerous, but very pretty purple flame.

The stuff inside the acetylene tank is an absorbent that is soaked with acetone All acetylene tanks actually have acetone inside, which is why they say "acetylene, dissolved." The acetylene dissolves in the acetone, much like CO2 in a soda. This allows much more acetylene to be stored in the cylinder, since acetylene can spontaneously explode if pressurized above 15 psi or so. Dissolving it in acetone allows it to be pressurized to several hundred psi since it's more stable. So, it's important to only use an acetylene cylinder in the vertical position, to prevent the acetone from getting into the regulator.

As I know there are polymeric acetic ester which can be made to fibers and used as acetone absorbents. I am a welder who needs this tanks. In Europe I habe only seen kieselgur, and in older tanks asbest (made until 1990s) as the absorbent. The solvent is most times acetone, but some contain dimethylformamide instead of acetone. So not all of them contain acetone

As a Mechanical Engineer (now retired) I'm always interested in seeing these kinds of "experiments"! 😁 Also spent some years in the Medical Gas Delivery industry. People HAVE to learn how to properly handle Oxygen cylinders! I saw first-hand in HS Metal Shop back in the mid-seventies what can happen, even with an "MT" (or nearly empty cylinder)! One guy was changing out one that still had some pressure left in it. Had the safety cap off (BIG no no) and tipped it over. Fell just right to hit the valve on the lower shelf of a (thick) steel welding table! Knocked the valve off clean! That thing took off straight for the rollup door! Didn't go through but that lower panel had to be replaced! 😱

Acetylene and oxygen make, I believe, the hottest flame in the industrial world anyway. Over 6000 degrees F. It makes the cleanest sharpest cuts and super-fast starts. Great for a shop, but ridiculous at scrap yards or demo jobs. Expensive, dangerous, the tips plug up or melt out in difficult environments. Propane is about 900 degrees colder. MAPP or Propylene is somewhat hotter. Best bet is just liquid propane for fuel gas.
@junkdeal Жыл бұрын
@Timothy Rettig the problem with acetylene is it is stored as a dissolved gas, sortof like CO2 in soft drink and doesn't come out of solution fast enough to mix quickly with the oxygen. The benefit with CNG is the high pressure it's under, and how quickly it will mix.
@brendontait6968 Жыл бұрын
@@brendontait6968 This is true. The acetylene is absorbed in the acetone, just like CO2 dissolves readily in water. In fact, if you over-draw an acetylene tank beyond its ability to release the gas, you will draw acetone into the fuel stream as well. Just like a 7-UP bottle-only so much of the CO2 will come out of solution at a time.

Acetylene tanks contain a porous substrate called agmassen and are half filled with acetone. Acetylene is highly unstable when in a liquid state or as a pressurized gas. When used in a torch it is combined with oxygen to burn, however acetylene can also decompose on its own without the presence of oxygen. At pressures greater than around 30 psi it can do so explosively. If they just put actylene into the tank by itself they could only pressurize it to around 20 psi (and even then it would be highly unstable and extremely sensitive to both shock and heat) and at that pressure the tank would hold so little gas that it would be pretty much impractical to use it. The way they get around this is with the agmassen/acetone in the tank. The acetylene is actually dissolved in the acetone (a weird property of acetylene is that exceptionally large quantities of the gas can be dissolved in acetone) when it is in the tank. The agmassen comes into play because if they just used acetone by itself then if any of the acetone were to accidentally be withdrawn from the the tank, or if it got cold and the acetone shrank due to thermal expansion, it would leave a an empty space at the top of the tank and the actylene would come out of solution and fill that empty space with highly explosive pressurized acetylene gas. The agmassen acts like a really stretchy sponge (this is an oversimplification but the best way I can describe it in layman’s terms), absorbing the acetone and preventing any open gas pockets from forming as the acetone expands and contracts due to temperature changes or if any of the acetone is accidentally withdrawn from the tank (for instance if the tank were to fall over on its side while the gas is being withdrawn).

The combinations are endless, trying different size gas bottles, with different gases, with different safes. I could watch that for hours. Thoughts?
@@taters-no4gj ideal. I bow to your enthusiasm.
Glad we can put this to rest now.
The stuff inside the acetylene tank is an absorbent that is soaked with acetone All acetylene tanks actually have acetone inside, which is why they say "acetylene, dissolved." The acetylene dissolves in the acetone, much like CO2 in a soda. This allows much more acetylene to be stored in the cylinder, since acetylene can spontaneously explode if pressurized above 15 psi or so. Dissolving it in acetone allows it to be pressurized to several hundred psi since it's more stable. So, it's important to only use an acetylene cylinder in the vertical position, to prevent the acetone from getting into the regulator.
Somebody passed AG mech 1 This isn’t supposed to be an insult
The absorbent material is called Acetate!
Maybe some call it acetate in englisch, I don‘t know, but it definitely isn‘t acetate. Acetates are salts and esters of acetic acid. As I know there are polymeric acetic ester which can be made to fibers and used as acetone absorbents. I am a welder who needs this tanks. In Europe I habe only seen kieselgur, and in older tanks asbest (made until 1990s) as the absorbent. The solvent is most times acetone, but some contain dimethylformamide instead of acetone. So not all of them contain acetone
@@TB-wi3sq well someone knows their English to German translations But you do need to use the American H instead of the German b thingy I’m sorry I’m drunk
Never knew that and I am a master plumber... common sense always tells one to keep the tank upright. Good info. Never play with acetylene, for professional use only 😉. It could end ones day in a hurry.
So much fun to watch this. Really appreciate all the hard work by all who made this video possible.
Been following Mark's failure analysis of Kentucky Ballistics 50 Cal. As a Mechanical Engineer (now retired) I'm always interested in seeing these kinds of "experiments"! 😁 Also spent some years in the Medical Gas Delivery industry. People HAVE to learn how to properly handle Oxygen cylinders! I saw first-hand in HS Metal Shop back in the mid-seventies what can happen, even with an "MT" (or nearly empty cylinder)! One guy was changing out one that still had some pressure left in it. Had the safety cap off (BIG no no) and tipped it over. Fell just right to hit the valve on the lower shelf of a (thick) steel welding table! Knocked the valve off clean! That thing took off straight for the rollup door! Didn't go through but that lower panel had to be replaced! 😱
you guys are so lucky you get to test this stuff looks like a lot of fun I would laugh all day keep up the good work
Edwin I have an idea... Get a clear pvc tent and put the cylinders inside, close the tent up and open their valves letting the Acetylene and oxygen mix and then shoot them.... Now that will be spectacular...
Yes, this would be beautiful!
Wouldn't the acetylene be at risk of spontaneous ignition? I'm no scientist but I do know it's one of the most unstable gases hence why it's dissolved in acetone.
@@Joe_Bidens_hair_fetish No it needs an ignition source. I used to fill 100 litre garbage bags with oxy acetylene and ignite it for fun. I tell you man it frikkin detonates like a bomb… once it shattered all the lights in my factory building and evacuated all the surrounding factories in the street… Even the fire brigade showed up… 😳
@@Joe_Bidens_hair_fetish thats the whole point ya dingus
@@Joe_Bidens_hair_fetish only when the pressure inside the tent reaches 16psi
Thanks for the video, Enjoyed, Really liked the tanks flying around.
Loving the science channel! The Grip 6 vid was well made. They make great belts
Now I think this is what Matt was hoping for when he shot similar tanks😂 love this!
Awesomeness. At that missed shot he adjusted the mount at 8:32, bumping the gun off sight
GREAT VIDEO, LOVE YOUR CHANNEL! The interior of the Acetylene tank has a cell that holds and absorbs acetone, you can not have just only Acetylene. Acetone stabilizes Acetylene Just found your channel and and you guys are the BEST! Love the guy who keeps laughing saying Cabron, always makes me laugh Well done all of you
Thank you. Awesome stuff.
Your videos keep getting better and better, but I hope you're not setting yourself up for failure, cuz anything less is going to be boring!!! GREAT Video!!!
It’s always a treat when Mark is featured
Thanks for the video men 👍 WOW that's awesome stuff 🙏❤️👍💯
Your videos are always satisfying when ever I'm having s bad day Edwin I put on of your videos and it puts me in a good mood keep up the good work dude
People don't think about it but there is a lot of pressure in those tanks and that pressure helps reinforce the steel walls making it seem a whole lot stronger than it normally would be.
I like the sound of the wind. So peaceful. Perfect for this.
always a great vid when Mr.Serbu is present.
Im glad you all could put on the white lab coats again together for this one, great video!
Dang, that's dangerous standing around those tanks with a severely compromised steel bottle. It may not have punctured it, but it seriously weakened it, and you even have an ignition source right there if it were to suddenly rupture.
oxygen lance goes brrrt
Pretty sure they wouldn’t suddenly rupture. Would be possible if they were being exposed to more heat while standing next to them. But considering it’s post explosion and they’re in a desert on a windy day under thick cloud cover, the bottle would be cooling by the time they’re standing next to them.
Shit man if it goes off then after not going off that whole time it was just meant to be
They are scientists and know what they are doing 😂
@@richardhoogendorn253 🤣😁😂😎
Every time I open KZhead, there’s a steady escalation of violence towards oxygen tanks. And I’m loving it. I’m trying to think of a suggestion for the next installment, but we’ve already left the realms of small arms lol. Going to need a 14in naval gun next.
Hey hey Edwin! Stopping in to say hello and glad to see you still thriving so well on here. I don't know how you get the nerve to do some of these videos, but I'm glad you do! Shoot your pool again with this 20mm!
I'm not sure why you use acetylene, it is dissolved in acetone and takes ages to come out, so it won't mix well with the oxygen. Maybe consider using a CNG tank, would mix much better with the oxygen and hopefully be a bit more energetic
I was thinking hydrogen. Try to make a cloud 🙂
Acetylene and oxygen make, I believe, the hottest flame in the industrial world anyway. Over 6000 degrees F. It makes the cleanest sharpest cuts and super-fast starts. Great for a shop, but ridiculous at scrap yards or demo jobs. Expensive, dangerous, the tips plug up or melt out in difficult environments. Propane is about 900 degrees colder. MAPP or Propylene is somewhat hotter. Best bet is just liquid propane for fuel gas.
@Timothy Rettig the problem with acetylene is it is stored as a dissolved gas, sortof like CO2 in soft drink and doesn't come out of solution fast enough to mix quickly with the oxygen. The benefit with CNG is the high pressure it's under, and how quickly it will mix.
@@brendontait6968 This is true. The acetylene is absorbed in the acetone, just like CO2 dissolves readily in water. In fact, if you over-draw an acetylene tank beyond its ability to release the gas, you will draw acetone into the fuel stream as well. Just like a 7-UP bottle-only so much of the CO2 will come out of solution at a time.
Set a tank on a set of parallel bars like tracks, shoot it in the bottom and see how far and fast it will shoot across the ground! Love the videos
Love it. Thank you Sir!
Love your "plinking", you guys have TOO MUCH FUN!!!
Acetylene tanks contain a porous substrate called agmassen and are half filled with acetone. Acetylene is highly unstable when in a liquid state or as a pressurized gas. When used in a torch it is combined with oxygen to burn, however acetylene can also decompose on its own without the presence of oxygen. At pressures greater than around 30 psi it can do so explosively. If they just put actylene into the tank by itself they could only pressurize it to around 20 psi (and even then it would be highly unstable and extremely sensitive to both shock and heat) and at that pressure the tank would hold so little gas that it would be pretty much impractical to use it. The way they get around this is with the agmassen/acetone in the tank. The acetylene is actually dissolved in the acetone (a weird property of acetylene is that exceptionally large quantities of the gas can be dissolved in acetone) when it is in the tank. The agmassen comes into play because if they just used acetone by itself then if any of the acetone were to accidentally be withdrawn from the the tank, or if it got cold and the acetone shrank due to thermal expansion, it would leave a an empty space at the top of the tank and the actylene would come out of solution and fill that empty space with highly explosive pressurized acetylene gas. The agmassen acts like a really stretchy sponge (this is an oversimplification but the best way I can describe it in layman’s terms), absorbing the acetone and preventing any open gas pockets from forming as the acetone expands and contracts due to temperature changes or if any of the acetone is accidentally withdrawn from the tank (for instance if the tank were to fall over on its side while the gas is being withdrawn).
Mark is one hell of a gun maker
I like how u can slightly see the bullet streak on the ground. So awesome
Mark is the man! Thanks for the collaboration
Acetylene tanks have crushed brick saturated in acetone which is probably still burning, I forgot a lot from welding school lol. but as a pro tip, never let your tank get completely empty! The acetone will get into the gas lines and eat the gauge and rubber hosing. Hope that helps!
Hey thank you aperantly nobody told my welding teacher this and we killed like 7 regulators
@@t.a.m.ttheallmightytexan3638 well maybe yall can remind him now that we all know! Haha
Just a word of advice, I would not stand directly in front of that valve head when it's laying on the ground after it has been charged so bad. It could come off of there in a blink of an eye at high speed and rip your foot off. Safety safety safety!!!! ❤️
Brother ... nothing about this is safe lol
OSHA has nothing on them
These guys arent safety experts on guns.
You can see the round as it is approaching the Target awesome 😎 video..
Thank You Grip 6 !! You guys are MINT !!
So your next experiment needs to be, have an oxygen tank up against some sort of either bank or something that will keep it upright but still allowing the bottom to be exposed so you can hit the bottom of the tank to see if the tank will go into the air. A flying oxygen tank, like a missal.
Maybe it would also work if they stand it upside down in some frame and shoot the valve
You jasper always make me smile. Nice to see mark again and the 20mm.
That 20mm round its about half inch diameter :D Brilliant Edwin, simply brilliant !! Nice video!!
Today's weather is 100% chance of blowing stuff up
Followed by chance of raining hot metal fragments.
the bottom of a high pressure cylinder is 3 times as thick as the sidewalls.
Yes thank you for doing this I have suggested this for a while using both propane and oxygen.
Fascinating 🤟🏾😁😁🔥🔥🔥🔥🔥🔥
Just by the way Royal walks, you can see he is still massively heartbroken for 50Cal Val. Poor guy ain't never gonna be right.
🤣🤣🤣
Richard Big Rich Royal Nonesuch is married....
I love Mark Serbu and everything he creates. One day I will own one of his .50's
I'd be perfectly happy with his RN 50
He is a scumbag. I bought two bfg50 rifles and they were nonfunctional scratched and rattly. He refused to fix them so I sold them broken, never fired. After politely asking him to fix it he sent me one of the rudest emails I’ve ever read. Terrible customer service, repulsive human being.
@@mrirondans this is between you and him. Not for here without two sides to the story.
Saludos y bendiciones desde Argentina Edwin!🇦🇷💙☘💪🏻🥰
Have you ever considered picking up some old LPG tanks with some gas left in them? I reckon they'd be entertaining to put into low earth orbit
He did that already
Low Earth orbit 😂
I doubt it, Blue Origin, I mean Blue Rhino will probably always be sub-orbital.....
Compressed air would launch a propane tank better than any scheme involving burning the propane inside. I've only ever built an air cannon capable of launching 14oz propane tanks, but the design scales amazingly well.
Whats wrong with new LPG tanks running at full rated pressure with gas?
Aiming the valve would be much fun 😊😊
Acetylene by itself is an unstable gas so it is filled with a porous material and acetone to help stabilize acetylene
It always nice to see Richard and Mark . The two of them are absolute genuine geniuses . 👍🏻
Wow!! Awesome I love these high pressure tanks shootings keep doing them going
Que arma poderosa .🇧🇷✌️👍
Çoxx
Mark needs to install an 90° optic to the eye end of the scope so, it can be aimed while firing. As the gun recoils the optics will slide past the shooter's eye but gives the shooter the ability to aim while firing. Great job and demonstration.
Thank you, that was SICK!
One of the best videos i have watched.
Great video, would love to see more of the bowling ball cannon
Another great video. Woulda been great if you had the slo-mo guys do the video capture for you.
Damn that Edward really cleans up nice!
Awesome video as always!!
Hi there guys, great video, keep up the good work, love watching your channel, David Stewart PEI Canada,,
You might want to add some drone footage from above. Just a thought. Love your vids!!!
Epic slow mo . That was cool
Thanks for the science experiments. 😁
Edwin, awesome as always. For New Years you should shoot a fully loaded propane truck. BIG FIREBALL!!!
You blinded me with Science!! Oh and shrapnel too! lol
Nice video. I was just going to explain the acetylene tank when I saw Rock Crawler’s comment. Acetylene by itself can explode if pressurized beyond a certain psi (maybe 20, not sure, but it isn’t very high).
This old Tony has a great video explaining oxy/acetylene tanks and torches.
Your videos are really cool I really like them
and this is why i like edwin: see's what works and what is awesome... _kicks it up an notch._
Man was that awesome, This brings the, blow things up spectacularly that we always tried for as kids.
You're the first person to show me how to use one of those belts
I love how you try to open an oxygen bottle with a burning flare next to it! But awesome video!
Cool video. I always wondered what would happen if you shot one lol 🤔😉🤫💯✌️ really BIG explosion nice.
Wow. 20mm sniper rifle. Next thing Mark Serbu will try making a bolt action rifle for the same 30mm used in the A-10 Warthog.
“You gotta say it with rhythm so I know when!” “1… 2.3fire!”
Oxygen will make anything burn you can make a cutting torch / thermal Lance from cheap steel brake line and connect a rubber hose to an oxygen tank use a sparkler or something hot enough to ignite the tip of the brake line steel wool works great and you can cut anything just make sure to turn it off before it gets too close to the rubber hose
Thank you sir
Good job bro edwin and your staff god bless
you just can not replicate the tank in the safe..that was priceless.
Holy shit.... How does this keep getting better
Awesome content! Maybe a large propane tank next?
Show na câmera lenta ficou melhor ainda 👏🏻👏🏻👏🏻👏🏻🇧🇷
I used an oxy acetylene torch set for a nice cutting flame but not lit and filled a logging truck inner tube to about 10 psi. Set a roll of toilet paper soaked in solvent beside it and lit it. Went back behind my truck a few hundred feet away and shot a 22lr round through the flame into the inner tube. We where up in the mountains at a logging camp. I bet you could have heard that a good 10 miles away if not farther. It was fun to be young.
Very nice fireballs from the tanks thanks for sharing
The Patrick Bullet sweet!
What kinda hoodie/coat you wearin. Looks good and I’m kinda wanting one
That’s crazy. Awesome
So much for getting your deposit back on those bottles! 😂
The new mic's are awesome -- hardly any background noise from the wind now :)
You are MENTAL going near those tanks after direct hits with no explosion.... 😱
Maybe I should watch the whole video before I ask a question next time but what is that stuff in the acetylene tank?
I feel like I just experienced a science event. Well done
Damn that looks fun... I'm jealous I want to have some of that fun!!!
Find a place to shoot. Get some flares, And lighters dig them in, on a side of a hill. 22 LR. When you hit one you get a fire Ball. cost $50 per hr. or so, Have FUN!!!
THIS SLOMOCAM IS AWESOME!
Super 👍 watching from srilankan 🇱🇰
I haven't seen the 20mm in ages!
Crazy people shooting badass things :) LOVE IT :)
