the reason the oxygen tank had a larger hole is because as the gas escaped with high pressure and heat it momentarily turned into an oxygen torch cutter and rapidly oxidized the metal the tank is made of. Because the pressure in the tank was mostly even top to bottom is widened the hole evenly creating a mostly perfect 2 inch hole.

The bottle of acetylene is at a much lower pressure, than the oxygen one. It’s designed that way, with that chalky or foam structure to keep the acetone dispersed equally, no uneven pressure. Acetylene bottles also have a couple of metal lugs up top that will melt in the event of a fire/bottle on fire. It relieves pressure. Basically they do everything they can to stop the acetylene bottle from becoming a bomb.

Nice to see Gasparito got his own bike. Glad to hear that the electric bikes have the wide tires on the bottom. When the tires are on top they tend to block your view.

Hey Edwin! Sir, thank you so much for making us a part of this video and for showing our leather holsters around! :) I'm glad you're this happy with your new holsters, even though they came in a bit beaten up. Hope you'll keep using them in the future! Regards, Al

Can we just appreciate how good of a shot edwin actually is. those hits standing up from that distance.. impressive

When the video starts with Edwin giggles, you know it’s going to be a banger… literally 😆

When I worked for Airco Industral gases back in the 1970s we use to service The U.S. Weather Service Helium Contract from Alaska. The cylinders were left out in bush and used for weather balloons. We received one cylinder that had a deep pointed bullet impact in the side of it. It didn't rupture and the cylinder still held pressure in it. We scrapped the cylinder obviously. .

I ordered a Craft holster 3 days ago, watched your video today. It made me even happier that I chose Craft for my leather holster. ANNND that demo of the tanks was AMAZING! I've often wondered what might happen if an O2 tank was fired at... I figured it would detonate, but not like that! Very Cool, thanks Guys!

I've been suggesting Acetylene for awhile now. I'm a welder, i use this stuff everyday and my inquiring mind has always wondered how big the explosion would be if someone sent a .50 cal through the tank. My wondering is over. Thank you Edwin! It was a big explosion true, but not as big as i would have thought. I also thought it would have caused a visible shock wave which i didnt see. I've done a few searches on KZfaq over the years to try to see if anyone has attempted this. I couldn't find much. Also, when you first ignite Acetylene from a torch is makes a loud "pop" that you just get used to over time. In theory, when shot, i would have thought that it would have created a sound like a crack of lightning at close range. This video showed very different. Oh, the perfectly round hole on the outgoing side of the oxygen tank made perfect sense to me. Its the original bullet hole of the .50 expanded by the oxy-acetylene rapidly being mixed making the tank molten and expanding the bullet hole outward. Thanks again, so much! Awesome video!

I had a feeling the muzzle blast was going to break the windshield.

I do love your videos, thanks for making them guys

Thanks for including us in the video. Glad you got to experience the accuracy of the ZF-5 right out of the box.

Edwin- Gaspari did I hit anything? Gaspari- YEAH, you hit the dirt over there… 🤣😂🤣

Even on the video sound track,hitting the cylinders are loud,this channel is insane,I love it.

Stay safe Edwin, your videos are amazing

I like when you do longer videos 👍🏼 It's scientific method 👊🏼 Thanks for all you do in the name of science!

Any video with great explosions is never too long!! This was the perfect episode.

I worked at a factory where we had an explosion in a ignition propane pipe-line. The pipe looked like it was cut out with a acetylene torch after. The reason for the fire was that a titanium valve had a spindle that had oxidized. This caused the valve to be thrown against inside of the pipe, causing a spark. Unfortunately this resulted in a fire inside a room full of tonnes of electrical cables. The fire then caused an explosion which killed a 18 year old apprentice. This video reminds me of this incident back in 2011. I still remember seeing the young guy lay on the ground like a twisted doll with a long, deep cut in his skull. I think he died in a few hours. Stay safe Edwin, and weigh risks!

Thank you for your videos. I really enjoy watching them from Kenya.

You guys are great!! thank you for letting us watch you blow that up!!

You guys are so much fun to watch! :) Glad I found this channel. 😊🙏👏

The ADHD is real with Edwin! 😂🤣 Love y'all 💚

Another very entertaining SCIENCE video. Great shooting, awesome explosion, funny. As soon as you said you were shooting THROUGH the truck. I was like. "No Edwin, don't do it!". Love the content. So glad I found your channel.

The cover picture for this is hilarious, with Edwin crouched a few feet from the tanks. Glad you guys went and hid behind vehicles for the actual shot. That was a very satisfying explosion. Well done.

edwin sounds kind of like a market seller when he's explaining all the guns he got and how they work

I've wanted to see someone do this (acetylene or hydrogen + Oxygen) for a long time!

I really like the thick leather holsters too. The Kydex are great and have their place. I use one myself. But, I do prefer the leather holsters. Those look premium for sure!

You guys have the BEST firearms videos!

I immediately go to this video and see you standing by 2 tanks capped with pumpkins and instantly know this is going to be a good one! Stay safe guys (I feel like I'm required to say that now that you've taken up destroying explosive gasses.)

The channel that never disappoints.

I knew that window was going to crack if not blow out from the rifle brake blast . Great fire ball ! Love the safe you shot on the last video !

I don't know how but I love your advertisement and I think you guys make the best videos by explaining everything that you use, by the way very entertaining video!

Great video as always. That explosion was amazing! RIP to the windshield.

love the vids man you guys are awesome keep up the great work you guys never fail to entertain love you guys

love you channel! Your doing all the things I wish I could do!!!!!!

I love leather holsters and the two u got are beautiful and look rugged but the little details and each design is outstanding and oddly enough my kids just asked me to pic out a couple of holsters so the can get me one for Christmass so thanks

Shout out the E-bike company for treating the camera man proper:)

It's good to know that at least one of them survived because the video got posted. I will leave such experiments for the scientists like you!

KZfaq interrupted this video 4 times for mint mobile commercials, you spent half the video on your sponsor and plugging various products. Jesus man you made a 5 minute video into a 25 minute commercial. Thanks allot

I like every single video you guys have! Keep um coming!

Believe me y’all uploading today is a treat

Absolutely love your passion for figuring out the toughest science questions!!❤

At the BOC gas pick up point in London UK where I used to collect my refilled oxygen and acetylene bottles, there was a full sized oxygen bottle next to the pick up point that had exploded at some time and the steel cylinder had split down it's full length and turned almost completely inside out, there was a warning message on a plaque attached to the remains that said, 'this happened because some fool used grease on the threads of the top fitting.' I never forgot seeing this blown up bottle and it was a very clever way to prevent a similar thing happening as it was so shocking to see and obvious that people had probably died in the explosion

As a welder I've been wondering this for a while so thanks

As soon as I saw him holding that 50 inside the car I thought “well there goes the windshield” 😂

The two friends who have fun blowing up everything they have at hand....and sometimes risk blowing themselves up 😅😅😅

Love your videos you guys are awesome!

Words can't describe how much I like this video

"Am I hitting anything?" "Ya." Dramatic pause. "The ground over there." EPIC!

Would be nice having some aerial drone footage of these explosions! Great video!

You guys are the best we all wish we could do that. It never gets old......

Every time I see a new video on this channel I think “They’re still kicking, huh?” Despite more and more crazy videos. Huge respect though.

Omg, I sense shrapnel incoming 🤣

Very impressive video! You did great on the promotions too! 👍

"I'm ready" love this guy's enthusiasm

The hole looks like it has weld marks because it was literally burning the metal of the tank. That's why it's so perfectly round.

The acetylene is dissolved in acetone and that is inside a foam like structure in the bottle, that is to increase storage in the bottle. Acetylene can self ignite above 1.5 bar. Oxygen and hydrogen should be even more fun 🙂

Fantastic Experiment, very interesting, thanks for showing, CONGRATULATIONS.

You have to like (❤) these guys. So much effort do things that are totally insane!

edwin you are very lucky to have good guns and your friend with you

19:50 I THINK that hole was enlarged because it was spouting a flaming jet which burned away the edge, thereby enlarging the hole.

Awesome video as always. - Do you guys know how super dangerous Acetylene is to handle? Self igniting at only 1.5 bars and so? For welding special dual step valves have to be used?

This is the best channel on KZfaq. Just two dudes vibing in the desert shooting guns at explosives

When you listen to Edwin talk about the products from his sponsors, notice that he actually USES those products too. Keeping it all relevant while giving the viewers what they came to see is an art in itself. Great job Edwin! *He just needs some sponsors who manufacture blast screens now!*

That was great but I was really hoping that they were going to be in a safe together with the flares inside that would have been awesome

I always liked shoot n steel with 300 win mag . It's impressive what they'll go through You got some cool vids .

Fun as always guys, thank you for the laughs.

Just when you thought these guys had learned their lesson 🤣

I'm no expert, but that looked like some pretty impressive pistol marksmanship.

Really a good shot!

I believe the hole is larger than you expected simply because the weakening of the metal from the initial entry point. In combination with the extreme heat and explosion probabaly caused the hole to expand beyond its original size.

Eddy "Am I hitting anything?" Jasperi "ya, the dirt" 🤣🤣☠️

“Let’s go a little bit closer” Literally the last thing I would do lol

I just love the way he says "I'm ready!"

you got cool guns and your blowing shit up. you can never go too long with that content.. gr8 job 😎👍👍

I gotta say, this guy is a damn good shot!!!🤯

Welcome to the Science channel by Edwin 😂

I don’t know why but you two on the E-bikes cracks me up.

like the wait between the shot and the noise of the tank being hit

The hole is the gas burning out the bullet hole so fast it melts the metal, it’s a massive acetylene torch

You really need the gasses pre-mixed in one tank - but doing that would make it insanely dangerous.

20:41 min 😂 😂 😂 Gasperito PLEASE don't kick it around 😂😂😂 I know that you love to these kind of stuff around! 😂 😂 😂

You should have tried this one inside a safe also. The safe acts like a pressure chamber which cause the expanding gasses from the tanks to rapidly increase giving you a way bigger booooommm.

These guys seem like such good people

A challenge, can you hit a target while riding your ebike? No one has done before.

When I saw that eagle holster, I thought "yup, we are definately living in pre-fallout times..." 🤣

That is one pretty gun! And accurate.

Just imagine if the Acetylene and O2 was mixed together in the same tank, stochiometric @ 3000 PSI!! Now that I would pay to see. I'm surprised these separate tanks even did what they did, adding the flares was smart.

It's so surprising how different it was last time when you put a cylinder in that safe, it made the explosion much fiercer as it was confined, So I think It would be super cool to put an OXY cylinder in a steel box/tank etc, or a steel coffin would make a massive bang, and a top video, But you would need to hide behind something this time.

Very entertaining thank you for posting.

I love the chain sounds

Hey DR Science if you want to have that Huge explosion like you did with the safe well the only way to Re create it is you need to put them bottles in a confined space. Shoot them u best make sure your mile away. Incredible too see 👀 I am glad you both are always safe. Love the videos keep them coming never a dull video ever lmao Rock on 🤘

It looks like the heat from the gas melted the hole wider. That's frikkin crazy!

the amount of product placement and ads is more mindblowing than any explosion possible in this case

Nice. I was hoping for this one.

Now just think how AWESOME these tanks would’ve been stuffed into safes.

Holy science Batman! Luv yah guys work, stay safe, sturdy & strong.

Excellent display!

love that jacket man, from where i can buy one?

You want a big bang, get a old propane tank like a 200 gallon house tank, mix the pure oxygen and some but not all the acetylene into it with a mixing valve ( rig a cutting torch up) then add a flare or two, move really far back and get behind something then shoot it with an armor piercing round.
