I served in the British Army Royal Engineers and we used to make these every time we did dems training. one time we could not get enough bottles so i made a shaped charge out of a catering size bean can with a copper cone and weld rods as stand offs. I think it was around 19 sticks of PE4 to fill it. It was very effective.
Typical grunt overkill using 9.5lbs PE4 (C4 equivalent) when our Point Focals could drill a finger-sized hole through 8” of solid steel using only about 2ozs! We used to deflagrate 1000lbs bombs using the same method! Deflagration is the chemical disruption of a bomb without igniting or detonating the HE inside it…
My understanding is that shaped charges are mostly about geometry. Given that the geometry is already there for you, this always made a lot of sense to me. Never considered chopping the bottle, I always envisioned it as a bottle full of explosive haha.
the Copper jet actually is not molten, it is somewhere between solid and super critical it behaves like a fluid due to the insane pressure it is subjected to, but its not a liquid as it is still solid.

I must admit that I'm rather impressed with how well they worked especially being able to penetrate an inch and a quarter of mild steel plate. I love to see a part 2 using armor rated plate such as AR 500 in the same thickness.

Nahh, the shrapnel from steel and molten glass from the wine bottle is much better for destroying a system or person than just the spalling from the soda, I still would never want to be in a tank or armored room with either of them going off lol.
You talk about the "punt" (glass void in the bottom of the bottle) is there much of a dimensional difference between the wine bottle and a champagne bottle? IIRC champagne bottles are thicker, and usually squatter... Your results don't really surprise me, the efficiency of the shape charge goes up with the diameter.
I think it has a flatter "punt" on the base. Definitely a larger diameter and wall thickness. There may be bottles that have a deeper punt that would be suitable. Good idea though!
Champagne bottles are made to withstand high pressures, upward of 10 atmospheres, so that they are stable under carbonation, wine bottles aren't made to hold high pressures. Punts are purely a wine serving/aesthetic thing that serve very little structural purpose.
@@HocusPocusist Do you think a normal wine bottle would pop under that pressure? My intuition is that no, most wine bottles wouldn't crack under 150 psi, but I can imagine them being extremely fragile and easy to break.

2:22 the wine bottle punt also helps a lot with making the bottle more stable. pretty much all glass bottles, mason jars, cups, etc will have some kind of dimple on the bottom. the dimple or punt (regardless of how deep it is) makes it such that the contact between the bottom of the bottle and the table will be a circle. even if there are one or two high spots on the circle, it will still be a lot more stable than if the bottom was flat
I used c4 for mine, cut the bottle at the very bottom then fill with c4 and use the bottom to pack into the neck and start the inverted cone then use finger to finish shaping. For the best geometry you want your explosion to start at the top of the neck. You can dig perfect ditches with detcord.

Not trying to be that guy, but figured I would share terminology for anyone who cares to know. The "backing" to which you are referring is known as "tamping" and the act of plugging a hole to contain the blast force such as in hard rock mining where you drill a hole and place a charge inside and then plug it is known as "stemming". So you tamp a charge that is on the surface of the material to be destroyed and you stem a shot that is drilled first. A layer of dry newspaper, followed by wet newspaper packed in to the opening of the hole makes for decent stemming and sandbags are oftentimes used for tamping. Be safe and be responsible! :-)
@@mildlydisinterested tamping is a term specific to mining and means to fill the hole with sand or something to concentrate the blast into the earth, its called something differen in these types of explosives. unless we are just making new definitions for words. this is also the era that calling your african TNT handler, a "powder monkey" was completely ok so to each their own ig.
This is highly informative: if I ever make explosives for some reason, never put them in a container with this type of bottom unless I'm fine with a big hole in everything under it. To be clear, I do not intend to make explosives at any point, but if I do this is a good safety lesson!
This type of video is a favorite for me as I learn something new that is different. I know that gunpowder is a propellant and RDX is an explosive. I am a machinist by trade & I own firearms & reload my own ammunition. Thanks for your channel.
Seen cutaway diagrams of shaped charges & theory a long time ago Works very well as your experiments show dynamically. Worked in a steel plant that made artillery warhead casings 40yrs ago. Nice demo💥
We made one just like this when I was serving in the Army. We used C4 and a nickel coin in the center of the cone on the bottom. We set it on an intact 4 Cyl car engine. Nothing was left of it bigger than a few inches. Completely destroyed it and cut the crank shaft in half as well.
Great videos guy, so jealous you are doing things that members of the EOD community never get a chance to do. One note the penetrator is just the tail end of the shaped charge and does not do the penetration we call it the slug. It travels at 1/12the velocity of the jet which does the penetration. Keep up the great videos. Can you tell more about the Gemini liquid explosive?
it's likely hydrazine based solution of ammonium, desensitizing organic nitrates and aluminium powder based on the VoD given, the appearance of opaque metallic flecks and viscosity.
@@domvasta You just became somewhat fascinating to a random Aussie guy who has always been interested (in a technical way) in explosives. Would love to know what sort of history allows you to, from all appearances, rapidly and accurately identify at least some explosives by sight! I'd love to pick your brain if it wasn't likely to get me in trouble. Hope this didn't come across tooooo strangely, I'm just impressed.
FYI you can cut these bottles by wrapping a cotton thread around it where you want to cut (thread used for cooking and holding turkey/chicken legs in place) after the thread is in place wet the thread with rubbing alcohol, make sure to have a bath of cold water ready deep enough to sink the bottle whole, once the thread is wet with alcohol go over the water and hold the bottle sideways(horizontal), light the thread on fire and rotate the bottle so the flame stays lit evenly, once is hot enough dip it quick in the cold water, that should get you a clean cut. we used to make gravity bongs back in college this way lol
hey, love the vids. for the next vid seeing just how dangerous "sparkler bombs" can be would be super cool. im curious if the sticks inside turn into shrapnal, it seems like they would but despite it there are vids all over youtube of these dangerous devices being set off by civillians with little regard for the dangers
When I was a kid these where my go to but I'd crush up the sparklers and discard the metal stick in them. You'd use three sparklers taped together to make a "Fuse" for it and then take all the chunks and powder and put them in a bottle of some sort and wrap the hell put of them with tape top to bottom. Looking back it wasn't the brightest thing to do but they sure did rip a chunk of dirt out if where ever they went off.
@@Donutkommando thats where you messed up, you need to use eletrical tape and make it very tight, after about 4 to 6 full wraps of tape take the box and wrap it around as tight as you can and continue taping for about 10 more full wraps, and if you do this do NOT use more than 6 boxes of sparklers it not a joke, very powerfull, it will make you mess your pants.
you dont really get and shrap from the sticks if you tape it very well most of them vaporize in the detonation but if your really worried about it use the ones on bamboo sticks
Here's a question, if you take one of these improvise shape charges and wrap the cone with copper wires, will it improve the penetration similar to the professional grade one?
I was thinking the same. As long as the fill is stopped before it gets up well into the neck. Even if volume is lost, 1.25" ar500 with room to spare is impressive...
I'd really like to see 1 more soda shape charge with the bottom cut off. I'm curious to see whether or not the glass bottom disrupts the projectile before it has a chance to make contact with the metal. Cutting it off may result in a more uniform/efficient entry/exit hole.
@@awashburn6944 Damn it, yeah I forgot that he used the bottom of the wine bottle. It's been a few days since I watched it. My bad, you're 100% right. Thanks for the correction.
Easy: the priming issue. Filling the bottle to the top would work, but also wasteful as we aren't setting these off against a ton of steel. The idea is to use the least amount of explosive to achieve max penetration. Filling a wine bottle with 750 ml of the explosive would be excessive for these tests. The other issue is the explosion lens will now generate differently as the shockwave travels down the curved path of the wine bottle neck. The idea is to have a uniform set up and a straight cylinder is the simplest design.
This reminds me of 3 letters, E.F.P. Got to see stuff like this when we went through the Joint IED Defeat training. If you paid attention, it was an eye opening intro to the average Soldier.
@@jlambuth Awesome! Maybe try electroforming copper cones and lenses for consistent thickness? It's much easier to do than it sounds, there are great instructional videos here on TH-cam.
@@chemistryofquestionablequa6252 so we are building a new mobile lab so I can expand our abilities. I'll look into this method. I am never one to turn down a good idea.
@@jlambuth awesome! It works for liners of charges, it's actually where I learned about the method. There's a video on "nux's channel" where he made one, I think he used PLX with good results.
@@jlambuth If stamping / casting and machining is out of the question, how about winding copper wire onto a conical mandrel, up to the desired thickness? You can get a fill factor of up to 90 % by winding cleanly, but maybe the entrapped air messes up the jet; or the nature of the layers mess it up entirely; I have no idea :°)
@@faustteufel9727 Pyrodex is not even in the same league as RDX, though I assume you know that and are considering the easy availability of pyrodex. You really shouldn't attempt to build your own, these often tend to be deletirious to life expectancy.
Reminds me of my ole "Absolut" gravity bong I had. Broke the bottom off in one piece. Could be set on the shelf when not in use. Used all rubber and glass "conponents". Sealed up quite well. Man that thing worked great. It was a real hit with everyone who tried it. Except those who turned ghost white after a try. Also had a couple people who couldn't return to work after lunch break. Lol.
@@jimf.1644 Matt is very close to DriveTanks. He can just go there with his armored Suburban and use their shaped charge and film the video there. I'm in the area as well.
Thanks for sharing. As always, fun to watch. The issue with the sodipop bottle charge can be greatly reduced by the use of a 1/4" dia tile drill bit. (By greatly reducing air compression & shatter differential) A single hole in the center of the bottom of the bottle should increase performance probably about 20 -> 40%. A series of holes around the bottle, (if consistent ht from the base) Should give about the same performance as the wine bottle S.C.s .
The way I have been cutting jars is clean and level - fill the jar with a liquid with a high boiling point up the where you want the cut; put it in a microwave oven and at a point it will crack right at the liquid level because of glass thermal expansion and stress. The resulting crack is almost a perfect cut.
Should try out thicker AR500 steels to see how deep shaped charges can penetrate! ;) Only 1.5" thick of AR500 steel is the deepest I've seen shaped charges could penetrate so far...
@@jantschierschky3461 A meter of papers, sure. A meter of AR500, AR550, AR600 or even 700 brinell hardness of steel?!? Fuck no! Ain't no RPGs or even missiles nor even nukes are getting thru all that...
@@7150285 absolutely no problem, you be amazed what a shape charge can do. I seen a panzerfaust 3 warhead punch through an composite tank armour over 800mm thick. I believe the hardest steel means nothing, it just melts
A proper punt size is key. Soda bottle has almost no punt while wine bottles have a nice punt. Usually shaped charges are more than just the exterior profile. Interior profile is important too
I'm pretty sure with the soda bottle ones it's the top part of the bottle that's doing the lensing, and the bottom half is just providing the right standoff distance, I think he said that in the previous video.
There's an important historical note that's missing from this video. It may be apocryphal, but there are a lot of old stories about French resistance fighters in WWII using wind bottles to make shaped charges when fighting the German occupation. Every test I've seen of wine bottles as shaped charges has worked well enough to lend credence to those old stories.
Jake once said he wasn't good on camera (way back). Either Jake was wrong, or he's gotten fantastic. I think he's always been great, but I can understand not being comfortable just yakking at a camera. Great presentation. Now on to my other point. I've been fascinated by shaped charges since I first learned the basic concept behind their use, when I was in basic training for the army in the mid 80s. It was explained (briefly) during the training on the M72 LAW and how it functioned. Since then I've read and learned more. Thank you guys, seriously, for this channel. You both explain fairly complicated information into easily understandable and entertaining content. Thanks again. Oh and make sure you keep an eye on *Buddy* to keep him from completing his plan for world domination. That little megalomaniac.
can you try a version useng metall funnels as liners also can you show the difference in effect with different speed explosives, how the penetration power varies from something as low as black powder to ammonal to TNT and then higher detonation speed explosives than TNT like RDX and HMX and Octanitrocubane - witch is the fastest detonating explosive i know of
1. can you show different materials for shape charge, just like you did with the glass? for instance what other materials would also work? wood wouldn't work? can plastic work? etc. 2. what speed is need for the composition for a shape charge to work? black powder wouldn't work, so what does? 3. then lastly what different shapes would work, for instance sharp cone vs more flat cone. with these 3 suggestions, you can ended up with a variety of speeds, shapes and materials to use for different circumstances.
More brittle metals (cast iron)tend to fragment like a shotgun but ductile metals (copper) are best for making 1 cohesive penterator for maximum penetration. I'd never thought of glass for a penetrator before. With its mix of properties I'm having trouble picturing if it would act more like a brittle of ductile metal As long as there is a concave shape with explosive outside it will function. Cutting charges can be pictured as a wedge shaped like angle iron across or around whatever it's cutting
The bottom of the bottle HAS to be indented otherwise the bottles would break VERY easily whenever you put them down. It's got nothing to do with manufacturing.
Wouldn't want a bottle full of liquid explosives to break when setting it down. Wouldn't want to spill that. Cleanup would probably suck - unless you have a fuse! 😂
It makes sense that the punt would do fairly well as a shape because of how its formed. the shape you get when you press in on a plastic material is also a shape that is extremely good at holding weight. In a similar manner, the shape you get when you hang a rope between two points (a catenary) is also extremely strong under compression. You can get a 3d version of the catenary by stretching something droopy over a hoop, like melty plastic
I once read some scans of old documents claiming that in some resistance groups, they used wine bottles with deeply concave bases full of gunpowder, for improvised shaped charges. The claim was that they were able to get actual detonation, and that it was at least somewhat effective against the armor of the era.
The dent at the bottom does actually have a use, I remember learning that it has to do with the pressure and instability, the instability of a flat bottom could come from expansion of the liquid
Legend has it during the United States Civil War, the hollow charge was discovered by experimenters using gun cotton they made a hollow (shaped with hollow letter forms) to engrave cannon barrels with USA. This would make a SMALL hollow charge to make the letters on the cannon barrels. An interesting tangent might be to use a copper cone to focus the effect (making a self forming projectile).
Secondary point of observation. in your soda bottle vs wine bottle shape charge tests, it seem that you lift all the wine bottles off of the targets by a few inch's but not the soda bottles. perhaps that gap allows the bottle to pickup speed before contact or maybe the direct contact is causing the bottle to fragment as the charge goes off...
I served in the British Army Royal Engineers and we used to make these every time we did dems training. one time we could not get enough bottles so i made a shaped charge out of a catering size bean can with a copper cone and weld rods as stand offs.

Ditto on the copper.

The bottom of the Punt could be filled with wax from the outside and potentially used for as the core for a lost wax cast; just and idea.

@@mildlydisinterested tamping is a term specific to mining and means to fill the hole with sand or something to concentrate the blast into the earth, its called something differen in these types of explosives.
unless we are just making new definitions for words.
this is also the era that calling your african TNT handler, a "powder monkey" was completely ok so to each their own ig.
This is highly informative: if I ever make explosives for some reason, never put them in a container with this type of bottom unless I'm fine with a big hole in everything under it. To be clear, I do not intend to make explosives at any point, but if I do this is a good safety lesson!
I'd love to see how reactive armor defeats shaped charges, if yall ever figure out a way to demonstrate that
This type of video is a favorite for me as I learn something new that is different. I know that gunpowder is a propellant and RDX is an explosive. I am a machinist by trade & I own firearms & reload my own ammunition. Thanks for your channel.
You should try to make a shape charge using a whiskey decanter!!
I think we can make that happen
Seen cutaway diagrams of shaped charges & theory a long time ago
Works very well as your experiments show dynamically. Worked in a steel plant that made artillery warhead casings 40yrs ago. Nice demo💥
I love this channel more and more every time you upload lol
Excellent work guys 👍👍
Thanks scrappy
We made one just like this when I was serving in the Army. We used C4 and a nickel coin in the center of the cone on the bottom. We set it on an intact 4 Cyl car engine. Nothing was left of it bigger than a few inches. Completely destroyed it and cut the crank shaft in half as well.
Great videos guy, so jealous you are doing things that members of the EOD community never get a chance to do. One note the penetrator is just the tail end of the shaped charge and does not do the penetration we call it the slug. It travels at 1/12the velocity of the jet which does the penetration. Keep up the great videos. Can you tell more about the Gemini liquid explosive?
it's likely hydrazine based solution of ammonium, desensitizing organic nitrates and aluminium powder based on the VoD given, the appearance of opaque metallic flecks and viscosity.
I'm sure the boys at the science madness forum could help with finding a formula if you have the chemistry chops to make it yourself.
@@domvasta You just became somewhat fascinating to a random Aussie guy who has always been interested (in a technical way) in explosives. Would love to know what sort of history allows you to, from all appearances, rapidly and accurately identify at least some explosives by sight! I'd love to pick your brain if it wasn't likely to get me in trouble. Hope this didn't come across tooooo strangely, I'm just impressed.
FYI you can cut these bottles by wrapping a cotton thread around it where you want to cut (thread used for cooking and holding turkey/chicken legs in place) after the thread is in place wet the thread with rubbing alcohol, make sure to have a bath of cold water ready deep enough to sink the bottle whole, once the thread is wet with alcohol go over the water and hold the bottle sideways(horizontal), light the thread on fire and rotate the bottle so the flame stays lit evenly, once is hot enough dip it quick in the cold water, that should get you a clean cut. we used to make gravity bongs back in college this way lol
hey, love the vids. for the next vid seeing just how dangerous "sparkler bombs" can be would be super cool. im curious if the sticks inside turn into shrapnal, it seems like they would but despite it there are vids all over youtube of these dangerous devices being set off by civillians with little regard for the dangers
I wanna see this also. I requested it a while ago. Hope they do it
When I was a kid these where my go to but I'd crush up the sparklers and discard the metal stick in them.
You'd use three sparklers taped together to make a "Fuse" for it and then take all the chunks and powder and put them in a bottle of some sort and wrap the hell put of them with tape top to bottom.
Looking back it wasn't the brightest thing to do but they sure did rip a chunk of dirt out if where ever they went off.
@@alna2530 I've never had luck with them. It would just shoot a fountain type effect out the end of the PVC tubing.
@@Donutkommando thats where you messed up, you need to use eletrical tape and make it very tight, after about 4 to 6 full wraps of tape take the box and wrap it around as tight as you can and continue taping for about 10 more full wraps, and if you do this do NOT use more than 6 boxes of sparklers it not a joke, very powerfull, it will make you mess your pants.
you dont really get and shrap from the sticks if you tape it very well most of them vaporize in the detonation but if your really worried about it use the ones on bamboo sticks
Holy crap somebody actually listened to my suggestion. I’ll mark this on my calendar.
Here's a question, if you take one of these improvise shape charges and wrap the cone with copper wires, will it improve the penetration similar to the professional grade one?
Great idea. The cone can be 3D printed and wrapped tightly with copper wire coil to coil
Learned about these from a sapper when I was in the army. They work!
do you have to cut the wine bottle in half? can't you load a whole bottle with the same amount of explosive so you don't have to use PVC?
I was thinking the same. As long as the fill is stopped before it gets up well into the neck. Even if volume is lost, 1.25" ar500 with room to spare is impressive...
Ease of priming, I'd guess. Probably a few small details.
Explosives go up just as much as they go down. If they left the top on the bottle pieces of it would be raining down for a bit.
@@Laugh1ngboy I never considered the test-range safety aspect. Fair point.
Also durability is my guess, in a survival scenario using this you don't want fragile glass bottles, plastic with a little glass part is more durable
Great video, looking forward to the next one
I respect jake Cody and Sean for using a pinot noir as improvised explosive device 🤣
My vehicle was hit by an 8 1/2 inch copper EFP. These are terrifying weapons and effective. Good video.
That's some poorman's james bond stuff right there, if you remember that book 😃
Former 12B here I LOVE your content....
Could you do the same thing with a lightbulb (like a flood light) if you remove the base and filament?
I actually had a teacher in high school named Ms. Head, whose husband was named Richard.
I believe any cylindrical container, preferably/typically with an inverted cone like the "punt" would work in the same way.
Love the science experiment type stuff you are doing now. Keep it up!!
I'd really like to see 1 more soda shape charge with the bottom cut off. I'm curious to see whether or not the glass bottom disrupts the projectile before it has a chance to make contact with the metal. Cutting it off may result in a more uniform/efficient entry/exit hole.
The bottom is the projectile.
@@psychosk8er No sir. If the bottom is the projectile how did the wine bottle shape charge work? The projectile is made of the neck of the bottle.
@@awashburn6944 Damn it, yeah I forgot that he used the bottom of the wine bottle. It's been a few days since I watched it. My bad, you're 100% right. Thanks for the correction.
Always been fascinated about these things
What's the reason for not just filling an intact bottle with the explosive?
Ease of priming, I'd guess. Probably a few small details.
Liquid explosive, just use a funnel to fill the bottle. No need to cut bottle or find plastic tubing
Easy: the priming issue.
Filling the bottle to the top would work, but also wasteful as we aren't setting these off against a ton of steel. The idea is to use the least amount of explosive to achieve max penetration. Filling a wine bottle with 750 ml of the explosive would be excessive for these tests.
The other issue is the explosion lens will now generate differently as the shockwave travels down the curved path of the wine bottle neck. The idea is to have a uniform set up and a straight cylinder is the simplest design.
@@polygorg Jake is the presenter so I think we can take his word for it regarding the reasons it was done this way...
I love these vids, and especially the humor in the nerraration, makes everything real fun. You guys are great!
Such a soothing voice. You are like a Mexican Mike Rowe
Miguel Rowe?
Miguel Roe soft
This reminds me of 3 letters, E.F.P. Got to see stuff like this when we went through the Joint IED Defeat training. If you paid attention, it was an eye opening intro to the average Soldier.
Best channel on TH-cam. Humor and explosions, what more could you ask for. Haha 💥💥💥
The cornball narration was outstanding.
Great vid!
Centimeters, pronounced, 'sin-tim-iters,' is quite interesting. 4:37
Guys, that was awesome 👍! Can you make a video concerning linear shape charges and perform some testing.
I would like to see you guys try to duplicate the EFP IED used by Iraqi insurgents and ISIS and such.
That is def happening
@@jlambuth Awesome! Maybe try electroforming copper cones and lenses for consistent thickness? It's much easier to do than it sounds, there are great instructional videos here on TH-cam.
@@chemistryofquestionablequa6252 so we are building a new mobile lab so I can expand our abilities. I'll look into this method. I am never one to turn down a good idea.
@@jlambuth awesome! It works for liners of charges, it's actually where I learned about the method. There's a video on "nux's channel" where he made one, I think he used PLX with good results.
@@jlambuth If stamping / casting and machining is out of the question, how about winding copper wire onto a conical mandrel, up to the desired thickness?
You can get a fill factor of up to 90 % by winding cleanly, but maybe the entrapped air messes up the jet; or the nature of the layers mess it up entirely; I have no idea :°)
Wew lads. That's pretty good. I saw the winebottle charges in some TM I read as a kid, never saw one about coke bottles.
Imagine doing this with RDX
Perhaps Pyrodex? A little goes a long way. (even though it's powder & not liquid)
@@faustteufel9727 muzzle loader powder? Seriously?
@@faustteufel9727 Wow thats pathetic.
@@faustteufel9727 Pyrodex is not even in the same league as RDX, though I assume you know that and are considering the easy availability of pyrodex. You really shouldn't attempt to build your own, these often tend to be deletirious to life expectancy.
Reminds me of my ole "Absolut" gravity bong I had. Broke the bottom off in one piece. Could be set on the shelf when not in use. Used all rubber and glass "conponents". Sealed up quite well. Man that thing worked great. It was a real hit with everyone who tried it. Except those who turned ghost white after a try. Also had a couple people who couldn't return to work after lunch break. Lol.
Y'all should do a collaboration with Demolition Ranch on his up armored suburban.
Of course it would penetrate. Even .50BMG (AP only) will penetrate his armrored Suburban.
@@prandomable granted, but I still want to see it
@@jimf.1644 Matt is very close to DriveTanks. He can just go there with his armored Suburban and use their shaped charge and film the video there. I'm in the area as well.
Thanks for sharing.
As always, fun to watch.
The issue with the sodipop bottle
charge can be greatly reduced by the
use of a 1/4" dia tile drill bit.
(By greatly reducing air compression
& shatter differential)
A single hole in the center of
the bottom of the bottle should
increase performance probably
about 20 -> 40%.
A series of holes around the bottle,
(if consistent ht from the base)
Should give about the same
performance as the wine bottle
S.C.s .
I'd like to see steel L and H beam cut apart with shaped charge.
The way I have been cutting jars is clean and level - fill the jar with a liquid with a high boiling point up the where you want the cut; put it in a microwave oven and at a point it will crack right at the liquid level because of glass thermal expansion and stress. The resulting crack is almost a perfect cut.
wicked
Hey do you know how to make a circular hole in a glass bottle? Asking for a friend in Colorado 👀
th-cam.com/video/SVu-hv0hvdM/w-d-xo.html
Make one of these
As I'm not the greatest at glassware work, I may not be the best resource here.
Carbide drill bit, slow speed and lots of water.
That shockwave is awesome the grass just pushes away and sucks back
4:36 cen tim eters…….. CENT E METERS!!!!!!!!
Great video guys! Can't wait to see the next episode....martini glasses?! James Bond would be proud!
Should try out thicker AR500 steels to see how deep shaped charges can penetrate! ;)
Only 1.5" thick of AR500 steel is the deepest I've seen shaped charges could penetrate so far...
Depends on shape charge, right size would cut through a meter or 2
@@jantschierschky3461 A meter of papers, sure. A meter of AR500, AR550, AR600 or even 700 brinell hardness of steel?!? Fuck no! Ain't no RPGs or even missiles nor even nukes are getting thru all that...
@@jantschierschky3461 my steel(s) will defeat RPGs like tooth pick vs a concrete wall...
@@7150285 absolutely no problem, you be amazed what a shape charge can do. I seen a panzerfaust 3 warhead punch through an composite tank armour over 800mm thick. I believe the hardest steel means nothing, it just melts
@@jantschierschky3461 tank armors especially WWII are not even that hard. The steels they used back in WWII are softer.
YES cutting it in half, that’s what I was wondering about.
A proper punt size is key. Soda bottle has almost no punt while wine bottles have a nice punt. Usually shaped charges are more than just the exterior profile. Interior profile is important too
I'm pretty sure with the soda bottle ones it's the top part of the bottle that's doing the lensing, and the bottom half is just providing the right standoff distance, I think he said that in the previous video.
@@samrowland2816 This is correct.
I'm loving these shaped charge vids
Why "cen-Tim-itters" and not "mill-IM-itters"?
Yes!!! I would also like to know! The important questions! 😁
@@taviscanale7821 VERY! ;)
There's an important historical note that's missing from this video.
It may be apocryphal, but there are a lot of old stories about French resistance fighters in WWII using wind bottles to make shaped charges when fighting the German occupation.
Every test I've seen of wine bottles as shaped charges has worked well enough to lend credence to those old stories.
Well, it's either that, or take the Polish approach of immolating the tank, crew and all, with homemade flamethrowers.
You should try cupping your hands and using that as a shaped charge
Usually one time use but it can be multiple uses
Jake once said he wasn't good on camera (way back). Either Jake was wrong, or he's gotten fantastic. I think he's always been great, but I can understand not being comfortable just yakking at a camera. Great presentation.
Now on to my other point. I've been fascinated by shaped charges since I first learned the basic concept behind their use, when I was in basic training for the army in the mid 80s. It was explained (briefly) during the training on the M72 LAW and how it functioned. Since then I've read and learned more. Thank you guys, seriously, for this channel. You both explain fairly complicated information into easily understandable and entertaining content. Thanks again. Oh and make sure you keep an eye on *Buddy* to keep him from completing his plan for world domination. That little megalomaniac.
I'll agree I have improved. This video took a ton of takes. I much prefer being the camera operator.
can you try a version useng metall funnels as liners
also can you show the difference in effect with different speed explosives, how the penetration power varies from something as low as black powder to ammonal to TNT and then higher detonation speed explosives than TNT like RDX and HMX and Octanitrocubane - witch is the fastest detonating explosive i know of
The way he said centimeters made my eye twitch.
1. can you show different materials for shape charge, just like you did with the glass? for instance what other materials would also work? wood wouldn't work? can plastic work? etc.
2. what speed is need for the composition for a shape charge to work? black powder wouldn't work, so what does?
3. then lastly what different shapes would work, for instance sharp cone vs more flat cone.
with these 3 suggestions, you can ended up with a variety of speeds, shapes and materials to use for different circumstances.
More brittle metals (cast iron)tend to fragment like a shotgun but ductile metals (copper) are best for making 1 cohesive penterator for maximum penetration.
I'd never thought of glass for a penetrator before. With its mix of properties I'm having trouble picturing if it would act more like a brittle of ductile metal
As long as there is a concave shape with explosive outside it will function. Cutting charges can be pictured as a wedge shaped like angle iron across or around whatever it's cutting
This video is going to be very useful in about 6 months around election time.
That was really fascinating.
Let's go Brandon!
Damn that's sick yo. I can't wait to try it out in my mom's back yard. Thanks for the tutorial!
Fun fact, the reason RPG warheads have that distinctive double cone shape is because it's a flying shaped charge.
RPG warheads are not all shaped charged though. HE (thermobaric and fragmentation) warheads exist as well.
@@getmeoutofsanfrancisco9917 And those often aren't there same conical design as the HEAT ones.
Also used in torpedoes
Boomboom314159 here, keep these vids coming!!!
I miss doing these types of experiments!!!
The bottom of the bottle HAS to be indented otherwise the bottles would break VERY easily whenever you put them down. It's got nothing to do with manufacturing.
Wouldn't want a bottle full of liquid explosives to break when setting it down.
Wouldn't want to spill that. Cleanup would probably suck - unless you have a fuse! 😂
Knowledge from this video stored Incase of apocalyptic world.
This guy doesn't know how to say "centimeter"
It's funny, let him do his thing.
This is what I call effective glass recycling.
It makes sense that the punt would do fairly well as a shape because of how its formed. the shape you get when you press in on a plastic material is also a shape that is extremely good at holding weight. In a similar manner, the shape you get when you hang a rope between two points (a catenary) is also extremely strong under compression. You can get a 3d version of the catenary by stretching something droopy over a hoop, like melty plastic
I once read some scans of old documents claiming that in some resistance groups, they used wine bottles with deeply concave bases full of gunpowder, for improvised shaped charges. The claim was that they were able to get actual detonation, and that it was at least somewhat effective against the armor of the era.
I hope these guys get a good slow mo camera, that would be awesome.
:D a bit of a stigma on explosives... made my day!
The dent at the bottom does actually have a use, I remember learning that it has to do with the pressure and instability, the instability of a flat bottom could come from expansion of the liquid
Dude this was...AWESOME WOW☢💣💣👍👀
Legend has it during the United States Civil War, the hollow charge was discovered by experimenters using gun cotton they made a hollow (shaped with hollow letter forms) to engrave cannon barrels with USA. This would make a SMALL hollow charge to make the letters on the cannon barrels. An interesting tangent might be to use a copper cone to focus the effect (making a self forming projectile).
Secondary point of observation. in your soda bottle vs wine bottle shape charge tests, it seem that you lift all the wine bottles off of the targets by a few inch's but not the soda bottles. perhaps that gap allows the bottle to pickup speed before contact or maybe the direct contact is causing the bottle to fragment as the charge goes off...
