So spalling is when a projectile or blast wave impact an armor plating causing the opposite side of the impact to break apart and become fragmentation. The effect that you were trying to stop is primary fragmentation, the projectile breaks apart into smaller and sometimes more hazardous pieces that continue to have down range effects. Go forth with new knowledge!

I think you could massively improve the coating by adding some sort of weave to it as a reinforcing matrix, like fiberglass or a simple medical bandage.

you’re correct. Everyone commonly misuses the terms. Splatter/splash is when the projectile does not penetrate an object. The round breaks apart and takes the path of least resistance creating bullet splash or splatter. Spalling is when the projectile penetrates an object and the material the projectile penetrates is projected forward creating spalling.

Our armor isn’t rubber coated (line-x etc). Our plates are compressed ceramic w Kevlar on top followed by some padding on top. It’s rated to stop a 7.62mm M-80 ball. Made by Ceradyne, inc. We tested it in Iraq during the 1st deployment and it would stop 3 M16 (5.56mm) rounds. After 3 it was toast, but any round bigger than that you better hope that you only get it once (or not at all of course lol) or get lucky if you get hit twice! Also, we had to change out our plates every so often because the integrity of the ceramic would easily get compromised because the corners of the plates would start to crack and crumble and spread towards the middle of the plate.

So glad *OG* got to stick a finger through something. *:)* Thanks for making these videos. Keep em coming.

Bullet fragmentation is the bullet breaking up; spalling is when metal on the reverse side of the armor breaks off without the projectile penetrating. Both can be bad in the context of a chest plate, but anti-spalling is particularly important on tanks, because the energy required to create spalling is roughly constant with armor thickness; against heavy armor it’s easier to design projectiles to create spalling that kills the crew than to design projectiles that penetrate.

Still a better idea than trying to make a bulletproof vest out of flex seal. Gave you a like for practicality.

Flex tape needs to change their slogan to "As seen on KZfaq" All these youtubers using it in their videos.

I wonder what would happen if you added a bunch of fiberous material with each layer of flex seal............something like burlap or God willing.....kevlar threads. That would be interesting

I keep looking back at these. It never ceases to amaze how detail-oriented and professional your team are regarding safety in these demonstrations. Well done.

Love these videos! :D Awesome as always!

I love the deeply sarcastic camera zoom

I think Red Green would agree that you would probably get better results with multi directional layers of duct tape equaling 1/4 inches in thickness. Interesting problem though, I think it deserves addressing. Thanks for the video!

NOW THATS ALOT OF DAMAGE

Would be interesting to see how it performed in a carrier. Pretty sure the nylon would have helped things out even more.

Someones been watching the latest demo ranch videos

Will it stop my ex girlfriends vengefulness?

The technical therm is indeed "spalling". "Spall" is something that breaks off something solid usually due to impact. Also applied to mining (spalling ore = breaking it into smaller pieces) and armored warfare. The ethymology of "splashing" reminisce about something liquid. As in, splashing canvas with paint.

Guys, you definitely have one of the better gun demonstration channels. Keep up the good work.

can you coat the AR plate with a gummybear?

Naniiiiiii!!!!! I wonder if flex seal can fix a folding table?

Great demonstration of the flex seal 👍😎

spalling is when the opposite side of a plate from the impact point fragments due to the impact on the other side. For example in ww1 tank crews wore chain mail masks because even though rifle bullets couldn't penetrate the armor, the brittle steel plate used would send metal splinters into the fighting compartment when impacted on the outside by a high velocity projectile. The interiors of some more recent tanks are lined with kevlar to prevent this.

Couldn’t help but hear Jeff’s, “hello everyone,” intro as Professor Farnsworth from Futurama saying, “good news, everyone!”

I have yet to see a Flex Seal tactical armored wet suit. Yet.

I would like to see you sandwich a soft body armor panel to the AR500 armor, using FlexSeal as the glue.

I like that you display proper range safety. Clearing weapon .ETC. Thanks LM

That's one thing I like about your channel is the way both you and the O.G interact with us. I hope you never change that format.

I see the thumbnail and my day is made, thanks for all your hard work, guys!

I like that you zoomed in on him clearing the weapon, for those people concerned that you're not being safe.

interesting...

I remember my grandfather telling me about his experience with bullet spalling while serving in WW2 (Pacific) his hands and arm's where all scared up from a near miss from enemy machine gun fire lucky for him he had on a welders mask at the time may he rest in peace

Taofledermouse, Can you do the car tyre silencer myth? Supposedly shooting down the centre of a dozen tires works as a silencer for high power rifles.

You’re the best I’m glad you’re still around 👍

that's good to know thank you for taking the time out to show and share

Watching the wake of the supersonic bullet in slow-mo 🤩

Try Napa Stone Guard. It has more tensile strength than Flex Seal.

Good video as always Jeff.

Keep up the good work I watch you guys every single episode

Matt at Demolition Ranch invented the wheel

So, random thought: What about homemade composite armor? Take a 1/2" deep steel cooking tray, fill it with 5-10mm alumina polishing balls, then fill the remaining air inside it with molten aluminum (or a structurally sound bismuth-tin mix, if you don't have a forge setup, though it's more expensive and heavy than aluminum and all) Keeping the alumina in with say, chickenwire fencing or a screen clipped to the sides of the cooking tray while the molten metal fills it, then after the metal hardens coat the surface with spray-on bedliner. Should be less than $100 total for the materials, and it would be interesting to see how it would hold up vs rifle rounds. (given the principle should be similar to that used in some composite tank armors)

Maybe a layer a fabric between some of the layers of flex seal might help?

I bet embedding a tough fabric layer or two into that flexseal would have helped even more.

Would be interesting to see how it would work if you chopped up an old kevlar vest and mixed some of it into the flex seal before putting it on. It would help keep the flex seal from splitting off chunks and blistering.

Can you turn it into a boat now???

I'd rate this on a scale of 1 to 10 as a 10! Great job, guys. Thanks!

Hey Jeff. Been a loyal fan of your work for a long time now. So I never forget to like your videos. Greets from Lithuania! 🇱🇹

Not enough scratch on the plate for flexseal to grip... and maybe not thick enough.. but il love the idea :D Love u taofledermaus ❤

Idea: a FMJ round with a gold jacket on a lead bullet called the FullMetal Alchemist.

Love watching your videos keep up the good work guys. That video from Turkey a couple of weeks ago was out of it. Good work guys.

Love these videos! I started watching this channel years back when you used to play with mercury!

All in the name of Science. Amazing video, as always.

Thats why i subscribe to this channel because uall read our comments nlt others they blow u off not a like or or love man u all cool love ur video man keep it up.

Thank you for the informative and very entertaining video! OG never fails to crack me up!

Please for the love of god don’t ever stop. love the videos.

Now, if you shoot a boat with a 12 gauge slug, then repair it with Flex Seal, how resistant to further shots will it be? I mean, that's a LOT of damage!

If you used something to reinforce the Flex Seal, like drywall patch tape, maybe the coating would have held together better.

Hey guys, just noticed you’re up over a million subscribers now, you’ve come such a long way since I found you a couple years ago (before you even had a patreon and were wondering if you could afford to continue making videos). So happy to see every time a new one gets published. You can really tell you guys enjoy doing this stuff. Please keep being genuine as your channel grows! Great content will always be more important than fancy editing or gimmicky product placements like so many other channels do now. All the best from Ontario :)

Crazy thought: would the steel and flex-seal stay together better if your steel was grooved like a non-stick p.... Oh, you thought of that. Yeah, probably very hard to cut a fine pattern of grooves two ways into a hardened steel plate, but I think it'd: 1) Allow the coating to hang on better under the impacts and 2) cause the fragmetns to bounce *out* rather than splashing *across* the surface.

Research shows that the fin on that ar's grip makes it a less deadly firearm therefore this test may not be accurate

Nothing turns me on like a California featureless ghost gun with faux 30 caliber clipazines.....

Awesome video. Definitely will be putting a few layers of flex seal on my bodies armor for personal use thanks for the information!

Picture of Officer Greg on the title card? Count me in, whats this wacky man up to now?!

Who else was hoping to here "That's NOT a lot of damage!" ?

I like so much how you and OG speaks!!! Saludos desde Argentina.

Jeff we know you care. I've commented several times on these videos and always get a response from you guys, whether you or the great OG ahah. Just wanted to say that I appreciate the work you guys do to entertain us and that I do think you listen to your viewer base. Wish you guys all well all the way from Portugal!

So sad to see that horrible featureless grip on an otherwise fine rifle.

wonder what difference it would make using burlap sandwiched between layers?

Great job as always my friend. Thanks! I bet if you took some layers of kevlar and embedded it in the wet flex seal and let it dry it may help with loose fragment containment. Love your vids.

...lol... I hope people have benefited from your endorsements and it cracks me up when I think about you guys being law enforcement thank you for the hours and hours of entertainment you've given me and please be safe out there

How would a flat sheet of rubber (nylon reinforced?) work instead of the flex-seal? You could perhaps use a contact adhesive to glue it on.

That's a lot of damage

Another great vid and love the filming of making the gun clear

Awesome video. You guy's rock. I look forward to all you're videos. Be safe.

These plates are slipped into a pocket in the vest and I'm sure the material is designed to capture as much of the splatter as possible. Good video, thanks EDIT: who in their right mind is down voting these videos? Wait.... I know...all the gun haters that can't wait to watch the next gun video, what a sad pathetic life. There is a lesson there somewhere.

That Cali compliant ar makes me wanna puke

I shot hand guns competitively for years. Montrose Colorado used to have a competition called the "Steel Challenge" where you faced off against an opponent and had to drop steel plates. First to the stop plate dropping won. I carried my chair, gun bag and ammo in a little red wagon like kids use. At the end of a day of shooting it would have a LOT of lead and copper fragments in it. And it was sitting WAY back from the targets/firing line. During practive once one of my 45 cal, 230 grain round nose all lead bullets splattered against the plate, bounce back and a dime to nickle sized flat piece of lead struck my buddies wife in the front of the calf. Just hit flat and stuck there. We pulled it off. Slight burn from the heat and painful but she was still able to compete. Lead hitting steel isn't safe at close distance (up to 20+feet even). I'm thinkng the cloth/other material of the plate carriers help mitigate the splatter. Love to see a video on that.

Geez... OG's point and shoot skills are ridiculous...good shooting

Why don't they just put a lip on the outer edge of the armor? Like a .25 inch protruding edge that would deflect the splatter. It would only need to be at the top too.

Glad someone tested this. I was curious about it, too. I do have a suggestion if you're willing to try. Like you said, rough up surface with burgundy scotchbrite or 320 sand paper and clean it with degreaser. But, mix a good amount of sand in with the flex seal as an aggregate. Then, of course, shoot that b**** with a 12ga slug!

I don't know how I missed this one. This was an AWESOME video idea!

I love the obligatory safety-troll-zoom-into-clearing-the-weapon. :D This is good info, Jeff...cheers! Chris.

I had never even thought about bullet splatter, though I'd heard the term before. Thank you! (Not only for an educational video, but one that was also entertaining to watch!)

I wonder if the flex seal spray would work better? Spray on multiple coats.

I hope to never need to use my plates, but this restored a lot of faith into my impulse buy from a few years ago

Bam nailed it... I've asked every channel that's dabbled with flex seal and who delivers Taofledermaus that's who

That .40 hits harder than the 9m That's for damn sure lol

#donttellmere! Wait a minute......

I do love this channel.

...Another informative video from Jeff, OG (and Danny) :D...loved the seeing the 5.56's trail from 7:44 - 7:47 Totally BALLISTIC, Dudes!!

That seemed to work well. But how would it work if you use layers of cloth and flex seal kinda like fiberglass is made. Would that work better??

That's a lotta damage!

Didn't do .556 against painted side. Other than that, awesome vid as always! I love watching your videos. Very informative and entertaining specially with the offhand commentary from OG!

It's always best to not change any of the variables when doing stuff like this. When you went from sheetrock to cardboard that will affect results. Also would have been great to have one more piece of sheetrock one the top of the plate to mimic a chin. I suspect if you placed just two layers of kevlar with your flex seal you would achieve the results you want. I would recommend sanding or grinding the ar plate to give the flex sewl something to grab onto.

splatter, spalling, or spatter? It's pronounced CARBEAN dammit!

There's pretty nasty results with that steel plate with bullet split in pieces causing several injuries in whom try to use this plate in a bulletproof vest.the real problem was is bullets split in sharp pieces and splattering into the person that wear it for protection like an fragmentation grenade.

You guys are great! I've been a fan for 6 or 7 years and enjoyed your 22 caliber stuff you used to do and wondered if there was a chance for you to revisit some of those "adventures" in the future?

Tao you are great man much love from portugal.

The 9mm on the flex-seal would have hurt.
