We finally made this one. Took us a while to get it done as well..........we had a bit of a setback. Many setbacks really. We have been at it with this channel for some time and it has been literally one thing after another. Sooner or later, we will finally hit our stride and YT won't smack us down like they usually do.
So what do you want to see next? Be sure to comment and let us know!
🔥🔥🔥
your footage seems a bit heat damaged...
I'd recommend comparing iconic grenades. That should be quick to do and educational...
Have you learned the cause of your fire? You're the 4th RUclipsr I know who lost his home!
(Arson, flood, hurricane, fire)
Honestly I just Love seeing ya guys back at it.. How about some different metal shape charges We know Copper works, what about say lead or aluminum, brass, etc. with all the Folks here on this channel I think we could come together and source all kinds of Odd shaped charge items to test.. though I would say we limit the hull size to say a 2-3 inch fit..
Would like to see what one of those shaped charges do to reinforced concrete.
I'd really love to see how a proper copper cone of similar diameter and angle compares to one of these glass charges.
The well-stocked partisan always has at least part of a roll of heavy copper flashing kickin' around.
It's not the glass that does the trick. It's the shape of the charge that does it. You shape the charge and remove the glass. It will do the same thing.
@@stephenanderle5422 From my understanding of the physics involved that's entirely not the case at all. The copper or glass is entirely necessary because it's the jet of molten* metal or glass that actually does the penetrating.
*I'm not exactly sure what the state of matter of the glass/copper is, as I understand it's debated whether it actually is molten or still some sort of weird compressed solid.
@@stephenanderle5422-- nope. Gotta have some kind of matter to be formed into the cutting jet by the progressing shockwave of the detonation.
@@stephenanderle5422 As others have said you need the liner to cut through the steel. ruclips.net/video/TT2t6RbVYVU/видео.html
God I love this channel. This got me wondering what would happen with the shape charge on the ground facing up. Maybe with a vehicle on top of the charge. Even a shape charge on the hood of a vehicle would be interesting. Keep up the good work.
Ooh like a pressure activated mine shaped charge?
@@noahscott2254 I was thinking more of command detonated but if you can find someone to drive the car over a shape charge I say do it. 😃
@@davidduafala3050... I have a nephew sitting next to me that has the experience needed for driving over it, (compliments of Fallujah, Iraq)...He also stated that you don’t have enough money to hire him to do it...!!!
We are getting some scrap cars to do this very test. We just have to clean up the mess after really well as blown up car frag is death on tires.
Shaped charges are actually commonplace in anti-vehicular mines.
I wanted to get this video done so long ago, but a lot of issues arose that delayed the project. Better late than never, right?
So what do people want to see next? We love your suggestions!
Old-school hubcap limpet mine? Maybe more of a breaching charge...
Recreate the hydraulic press channel thermobaric bomb. That thing is almost unbelievable.
Id like to see metal ammo can with blackpowder versus a wooden ammo crate with blackpowder in a fire.
I've done civil war reenacting in the past, and the national park safety regulations mandate storing black powder in a modern steel ammo can, and not a wooden ammo crate. I've heard the original wooden ammo crates are actually safer, they are supposed to take longer to detonate in a fire, and should produce less sharpnel. Id be happy to see you test it, could be interesting.
Gun cotton production, detonation, and safe handling.
Really great to see another vid from you guys. So sorry to hear about the fire and buddy 😢 I would love to see you guys synthesize CL-20 and do some tests with it
As your channel has grown your presence on camera has improved immensely Jake. I remember when you practically hid from the camera during recording, but now you're a natural in these videos. Thanks for making them. Also RIP Buddy.
Be safe out there, and take it easy man.
Thanks man. I still struggle on camera as I am not the most social by nature. Taken a lot of speech therapy to also address my speech impediment.
@@jlambuth You do a solid job man, and the content is A+. You guys are one of few that I immediately jump to watch when new video posts
@@dwastart I appreciate it my man!
@@jlambuth That means your brain moves faster than your tongue... many people have the opposite problem... Consider yourself Blessed!
@@jlambuth Just piling on - you've definitely put in the work to conquer that demon and relax with the camera. Well done, the "um, ah, um, kaboom" guy from the old videos has been replaced by some kind of smooth talking (but low budget) Imhotep. Personal growth on video!
I'm very very pleasantly surprised with the penetrating power there. I think that's probably the best I've seen them do
I'm glad you guys are slowly getting back into things. Take as much time as you need, the videos are well worth the wait.
I think it would be fun to do a range test with the shaped charges to see how far they send material. Maybe compare ones of different size or material.
Can you do a shape charge against a sledgehammer head Longway, and various rocks?
Also, would there be a difference between glass and copper liners? I imagine you could make a 3D printed or wooden form to shape copper sheet which could be cheaper if you consider time.
Copper is denser and more ductile, and thus has more momentum and supposedly creates a more cohesive jet.
I've seen people make the cones by electroplating copper onto approximately shaped forms.
I was wondering the same thing, given the amount of work to prep a martini glass, it would probably be easier to just stamp/hammer out a copper cone from some sheets. All you need are some forms which a lathe could make, and a hydraulic press from harbor freight.
Given the cone shape I wondered myself how this would work. Impressive
Great Physics Instructor Thanks Boss.
Working with fireworks for 5+ years, this channel is a wonderful pyro outlet 💪🏼 there's allot of science that goes into this shit I love it
Son... Dad are we pyromaniac's?
Dad... We arson
Shocked u didn't know about the string trick for clean glass breaks. Neat video:)
Best of luck my friend
Awesome video! I like the balance of jokes and playing with explosives. Is so fun to watch!
Yall are great! I'm happy that the fire didn't slow yall down too much. Keep it up!
Always been curious about shaped charges. Glad you guys are back, hope everything smooths out!
Sweet 👏👏
I've been waiting for this one, you guys are legendary
Keep going, this is really interesting experiments.
Shape charges are freaking amazing
Thank you for the video!🤩👍♥
Thanks for the video!
perchance you could use a sandblaster to trim glass? not just stems but maybe even turn down the OD so they'll fit your pipe. keep up the great work mates!
great vid! your presentation skills have really developed nicely.
Sorry to hear about your run of bad luck, hope things turn around for you soon.
Keep up the great work!

Great to see another video from you guys! So sorry to hear about the fire, and the puppers 😢 RIP buddy. I would LOVE to see you guys synthesize CL-20. When???
"stacked them like a pile of Dennys pancakes.... only more appealing"
🤣🤣 You guys have great jokes!
Great video guys and perfect timing for me. Currently got an essay to write on computer modelling of shaped charges for my OME degree.
I love the shape charge videos
I do not want to blow anything up but the "deflective" glasses and A case of Good Gin and a couple bottles of Vermouth would get a thumbs up.
A good way of “cutting” glass is to use a nichrome wire wrapped around the glass object (in this case the stem, thought you could use the same technique to decrease the diameter of the glasses at the lip, too), and run a current through it until the wire glows white hot. It heats the glass in a very localized way, without heating the entire object. You then just dip the heated glass in cold water, and it will fracture at the point where the wire was wrapped. Obviously, you don’t want to dip a live wire in the water, so either remove the wire quickly after heating, or disconnect the power from the wires. There are videos that can demonstrate how to use this method properly, though it will probably still require some trial and error on your part.
Here is a RUclips video showing the process. There are others, as well:
ruclips.net/video/X1INKWrOlO8/видео.html
I was about to pipe in about the hot wire method, but was also going to add that torch smoothing could go a lot smoother preheating the glass in a regular oven, and then popping it back in the oven and turning it off to cool extremely slowly.
@@mfree80286 Also an excellent technique!
Glad to see you're back at it.
Always a very informative and great vid.
What I as a viewer would want to see from this channel:
* EFP vs tungsten cube
*EFP vs ballistics gel w/ar500 steel armor (multiples?..)
* Maybe some sort of test to see if you can aim an EFP from a distance
These are all the things I wondered about as a 12B and have never been done before to my knowledge
I love the attention to detail in these videos and the fact I still have no idea how glass can penetrate steel plates..
Turn the glass into a molten slug. Fire it at high speeds(faster than a gunshot) while focusing it all to contact the intended surface at a "pinpoint" location... Best way to visualize it. If that doesn't work, visualize a meteor strike
I would surmise that most of the damage is being done by the shaped charge itself, and not the glass. At the steep angle they're getting with that wine glass, I don't think they're forming much of a penetrator, but rather atomizing the glass. A shaped charge will penetrate steel without any type of liner.
Great demonstration as always keep up the good work and have a happy Thanksgiving
Always bringing the bangs. Love it!
We are here for your infotainment. Lol
it's nice to see you guys making homemade HEAT (high explosive anti tank) devices
Back in the day I did play with some glass. If you take a triangle file and Edge all the way around the stem you should be able to have a pretty good break. You can also try this using heat to try to get it to crack smoothly and cold. AKA so other than just using Brute Force which you can use after scoring this around you can do this by heating it up in that area and then dipping it in cold water you won't have to get crazy with it. A string with some kerosene would be sufficient. Keep up the good work.
Boom! I love it!
Hey if I were to make some different copper liners for linear shaped charges with different thicknesses and different apex angles could I send them to you for texting? I work at a sheet metal fabrication shop and have access to a press brake for fabrication. Let me know would love to see more videos like this, thanks
great video
When you cool the glasses down, bury them in vermiculite and they will cool more evenly. There will be fewer breaks then. You can get vermiculite at a nursery as soil for cacti.
You comld also try tying a string soaked in lighter fluid around where you want to cut the stem. Light the string on fire and let it burn for a few seconds and dip the stem into cold water. It should crack in a ring where the string was. My grandfather used to cut bottles in half that way. Cutting a groove around the stem with a diamond grit file could also do the job of giving the glass a weak point to break. You can shape the bottom of the glass with diamond grit files as well. I have used diamond files to fix chips in the rim of drinking glasses, so I know you can file glass without it breaking.
thanks for showing this it was one of the expedient field methods... much obliged next can you do the diamond charge
This is why America is the best place to be. Information is supposed to be free.
Love your work. Watch out for the RCMP.
I would love to see you guys experiment with linear shaped charges as well! Cool video!
You beat me to it! I'd love to see some improvised linear charges, they've always fascinated me.
Welcome back fellas. We missed ya
Big BOOM! helps make the stress go away.
I once used about two ounces of C4 to put a two inch lab sep funnel (minus it's stem) through a peice of two inch cold rolled plate steel from a six inch stand off. Molten spatter shaped hole about an inch in dia. on top of the plate and a 1/2 inch perfectly circular punch hole, in which you could see the layering of the steel,out the bottom. It was impressive.
Great Job Love the vid
Great video guys. Have you tried making a copper cone and using that as the penetrator?
Nice video! Have you ever tried to make explosive reactive armor and test that against chaped charges?
I would love to see a video explaining history of explosives. Its an interesting subject
Ooooh. Good idea.
Explosions & Fire
You guys are getting better all the time 👍
Did you try the firery string trick to remove the stems from the martini glasses?
Great video! I’ve cut other glass with an angle grinder using the NOT CHEAP disc and that worked well. Would thin sheet metal curled around odd size wine glasses, making a “sabot” inside of PVC TUBE feasible?
An an explosive detection dog handler, this stuff is invaluable knowledge to me. 👍👍
Great video.
Awesome!
Very nice
Great video. Have you ever considered adding a metal or tin lining to the inside of the cone of the shaped charge?
I worked underground for 30 years . And we would have to deal with large chunks or rock . To big for our machines to move . So we would have to blast them with shape charges to break them in to small enough chunks for us to handle. We would use oil funnels filled with emulsion but with the big end down . It kind of confused me when I seen you using them the other way around. But most of the shape charges are like the way you use them . Great channel guy I will try and send a few bucks to help you out .
Ordnance lab, I have been a fan of you guys since your very first video and I watch every single one. You guys are great! Thank you for yet another very entertaining video. One thing I'd like to see is, how well does a bunch of water help to direct the blast? Like when you were blasting trees, it didn't work very well because a lot of the energy was going away from the tree. But what if you had like, a garbage bag full of water all around it?
Fun one. Glad that you're able to get back at it after all those taint-kicks.
Just wondering, did you try the score and hot then cold water? I've had great luck with that technique. Good enough that I cut a pint glass that would hold a beverage (let's call it "water") to get my friend that only bought cheap water but really liked to take a swig of my micro-bottled water if I walked away.
Beautiful.
What about glass or copper powder?
Geez this guy should be a spokesperson for an antidepressant commercial!
Perhaps Jake should become a voice actor for big pharma.
I really appreciate the hands-on science. You guys need to make T-shirts with explosive memes on them. I'd buy one with just your Logo on it.
Nice, to help focus blast and assist in the inversion can I sugest raising the height of your explosive charge by adding more explosive to top of charge building it up in a cone shape will reduce the amount of explosive needed..
"This guy went DEEP"
Great quote
had a very interesting thought when i was messing around with a mtn dew bottle involving gemini
I'm too lazy to look at all the comments, so apologies if someone else suggested this first, but why not leave the stems (and even the base) on the wine glasses, and just pour the liquid explosive around them? What effect do you think that would have on the lensing of the penetrator? Would it prevent it from forming, or maybe help focus it? Just a thought or two... By the way, glad to see you all back making videos. Hope things go better for you from now on!
Did you guys think about making the insert/penetrator out of very unstandard and unusual materials? For example - lead, powders (sand, iron oxide, powdered iron, starch etc), maybe even some liquids, silicone for moulds, cement... All of this materials can be easily formed to the cone shape, by casting them in 3D-printed moulds, or containing them in 3D-printed sone-shaped cases. Results can be very intresting I think :)
Tungsten powder and resin would be cool, I'm guessing it wouldn't work too bad. Or even better, tungsten powder impregnated into copper...
Gold, Platinum and Paladium are best since density is bigest. Just a bit expensive...
Water jet, perhaps water could act as a penetrator before it evaporates.
magnesium powder mixed with a resin?
i want a non-Newtonian liquid penetrator
Diamond blades and files are your friend when working with stone to glass 😎
Something quite funny about an explosives channel advertising e-bikes - rather appropriate, lol
A x-mas glass ball for x-mas tree decorating might be perfect.
wonder what the behind armour effects are? ballistic gel block to catch the spalling??
I wonder if you can miniaturize a shaped charge to fit in a 12ga. slug and make it detonate on impact.
7:09
[Wii Sports Announcer] Nice throw!
Cool Videos!
The explosion is essentially a chain reaction that escalates in size and detention velocity. You go from detcord to det cap to main explosives.
But does it have to be a single main charge? Would there be a way to use two slightly different explosives for something like a shaped charge where the other half detonates later, after its pushed "inside" the target?
may be you can use a wet diamond grinding disk on a stand/fixture to grind it clean with a good angle. and/grind the neck round,may that can improve the profile.
Righteous!
What I would Absolutely LOVE for You to do is a Shape Charge Demonstration of How Shape Charges are Used for Say Cutting Through Support Beams like those used in Bridges !!! So hard to Truly tell How good the shape charges that You are Building for their Effectiveness . Without showing how effective they would be at doing a demonstration showing with the Purpose of how Shape Charges that the Military use are mostly used for !!! Thank You
Sorry to hear about your fire 🔥, I had the same it takes a Minute to get going again!
Welcome back
You might have already got this advice but if you make a pair of tongs red hot and then place them on the glass stem you can easily snap the stem pretty cleanly. Like how the sommeliers open old expensive wine bottles
I'm not sure whether I've already asked about this, but have you guys heard about cylindrical liners? I've only ever found little info, but they can be made by cutting copper pipe to length, and supposedly require minimal standoff distance.
The metaphors and similes definitely invoke cool mental images
9:01 "not as well as we had hoped". I have a suspicion that the shape of that squared tube was also to blame. When it penetrated the first layer that particular shape likely had a "dampening" effect since the "first" metal plate also caved in (which can be seen) i.e. didn't offer 100% resistance to the charge. This may have damped i.e. slowed down the forced and removed a little force owing to the distortion of the metal bending down. The velocity will have been reduced very slightly but possibly enough to thwart the force or power needed to penetrate the next layer a few cm below. Can this be? 9:04 the distortion providing the dampening effect can be clearly seen.
I tought shaped charges needed copper to make a jet of melted material to knife through steel. Can it be that glass does this or its just the shape of the explosive that directs the energy to the metal?
I would love to see a shape charge comparison, could you also review the TM31-210 book
Curious why you didn't score the glass stem with a file and bend like cutting most glass tubes and rods?
I'm early for a change!
48 min in and looking forward to the video! 👍👍
Was breaking off the stem really neccesary? In ww2 the 7,5 cm Gr. 38 Hl series had a hollow aluminium tube going down the middle for the flame of the imoact fuze to go at the bottom of the round, so is the stem really a problem?
Loved it!!! Very informative and entertaining. My question is what is the relative cost of the Gemini material/100gm ?? What other material could have been used to make the glass lense and penetrate the target areas??
Thank you for the work!
Gemini is Ammonium Nitrate (couple bucks a pound), Nitromethane ($100 a gallon), and aluminum powder (also a few bucks per pound). I can't remember the ratios off the top of my head.
Been following the shaped charge series. Saw the Tannerite one, not surprised that it didn't work. But black powder or flash powder? Given that Charles Munroe discovered the effect back in 1888, black powder would have been fairly prevalent. Just randomly curious and I really like my fingers and eyes so... How about you guys do a black powder / flash powder shaped charge?
Man i really wish i can make my own explosives. I heard about some people talking about their experiences 50 or so years ago being able to experiment with various explosives during their childhood. I wish I could be like them
I've got an idea that'll tickle your technical side... an expanding rod warhead. The trick would be in both material selection and a liner that would cushion the shockwave enough to not tear the expander apart immediately. Imagine what it would look like with a field of test dummies and targets sliced in two with a supersonic expanding hoop made from steel cable.
Also curious about the effect of using a cast polymer with a heavy metal content as a liner, formed in a proper cone shape (i.e. inside a stacked funnel, or martini glass parts). Epoxy loaded to it's physical limit with copper powder, for example. I actually think there are 3D printed polymer/metal matrix parts available now through online services that are intended to be hot sintered or just used as is...
The original Coca Cola glass bottle with the deep dimple in the bottom became a recognised shaped charge for disabling engine blocks during WW2. Filled with 'plastique' or thermite with a timer and detonator, special forces took out as many axis vehicles/aircraft as they could during various raids behind enemy lines.
Love every Ordnance Lab video, hope y’all are doing well in spite of everything.
I’d enjoy seeing a recreation of the “Sticky Bombs” from Saving Private Ryan, about 1.5 LBs of TNT next to a steel road wheel.
Funny you say that. Sean was watching that very movie today. The sticky bomb is def a must. Especially as we have tons of TNT.
@@jlambuth gotta use a period correct military surplus wool sock, i can just see the outraged comments associated with a cotton crew sock.
@@DH-xw6jp the screams of a million clonerbois would leave me deaf.
@@jlambuth The Brits mass produced a sticky bomb that was composed of a spherical rubber bag with a metal handle, the bag was filled with gelignite and coated with extremely strong contact adhesive. My understanding is that it functioned effectively as a HESH charge, causing spalling from the inner surface of a tank's armour.
Supposedly the original intent was that soldiers would throw it at the tank, where the glue would stick it in place until the fuse burned down. However the glue often failed to stick if the target was dirty (as tanks often are) so braver troops resorted to running up to the tank and slapping the charge down onto its flat upper surface, before making a hasty retreat to avoid the explosion. It was a risky weapon in many ways, as the glue could also stick the bomb to your clothing...
@@nerd1000ify I've seen this grenade you speak of. It was encased with a plastic housing that kept the sticky part untouched.
That's a gnarly shaped charge, similar to the EFP's in principle that we had to deal with in the Sandbox.
I have a thought-- would getting one of those Home Depot prefab homes be a viable option for y'all to put on the worksite? Takes out half the headache of getting a new structure built, just has to be finished on the inside and have stuff like electric and water run.
Looking forward to more!
