  • I'm going there in the supermarket to buy some C4 and we'll be back to have fun ..

    vou ali no supermercado comprar um pouco de C4 e já volto para a gente se divertir.. kkkkk

  • this scares me

  • And why the hell you post vids like this you and discovery to, this is like so educating for terrorist they can't wait to try this kind of shit.....

    I am sorry but this is my opinion ....

  • @wingb83 The fact is this type of device's construction is common knowledge to forces around the world. Military units and terrorists alike have been using them for decades, this video isn't giving anything away.

  • @LowLevelHellProject I agree with you but my opinion is that things like this should M rated

  • nice animation

  • Comment removed

  • The real weapon of mass destruction (Re: 9-11)

  • if you just put the explosives on the plate it doesn`t cause that much damage?

  • @dailydols Because the explosion mainly goes up the way and sideways as there is less resistance and therefore less damage to the steel. If you focus the energy of the explosion, as done by using the tube the copper cone and explosives were put into, the energy travels downwards onto the steel.

  • 1:51 - "FIREINDAOH!"

  • but will it kill gophers????

  • Dat Quality

  • lol those guys are noobs 'as of course since we have absolutely no idea as to how the munroe effect functions, we shall just try to reproduce some schematics we found on the internet and hope for the best'

  • that's how anti-tank rockets since the bazooka and panzerfaust and now the RPG-7 work. Defeated by pre-detonating plates, wire, grid, or active armor.

  • @biukucanoe thats why the brit armour units has elecromagnetic armour deafets all shaped charges and renders heat rounds from other tanks usless hence one of the reasons britain stuck with rifield tank guns and not smoothbore as heat is 1 of the primary A.T shells on smoothbore

  • @thelleht well they used x ray and termal imaging but the jet is not molten, its 450 degrees, copper melts at 1000 some degrees, but then it moves at about 20.000mph, that why it mold the copper so easy, 25 Gs of power behind it

  • There is a video out there somewhere that shows a missile moving at about 400 mph. On the tip is a special shaped charge.  When the missile hit during the test run the explosion was quite unimpressive. But it punched a 2 inch hole through 6 feet of solid steel.

  • beautifull!!!

  • a buddy of mine used this to destroy a fleet of vehicles in a combat operation...just set the charges on the hoods of the trucks...imagine what it did to the engines!

  • @thelleht Hey thanks a lot for clearing things up. one more quick question if you don't mind. I noticed the other end wasn't capped (I think), wouldn't all the explosive power just release out the open end instead of collapsing the cone and making a jet. Also, what if a metal cone was in a plastic tube, say pvc, wouldn't all the weaker materials just explode before the metal cone could break? thanks a lot.

  • @bornfedslaughter no the material are there just to form a shape not to hols in place and explosion, the matera burns at 5000m/s way to fats to release the energy anywhere else then in the shaped charge, it just wotk wonderfully, thye even uses glass ad a shapes charge and its better penetrator then copper

  • it's Principe of working of old soviet rpg29 antitank missile ))))))

  • Black powder can do the job too. But of course, much less penetration power.

  • homemade rpg!!!

  • hmm interesting, so in movies when you see bank robbers blow open a vault with non-shaped charged explosives is innaccurate, in real life you would use a shaped charged explosive

  • I wish he would've explained the shape of the cone better, didn't quite get it.

  • @bornfedslaughter Assume detonation from the top center.

    If the charge were a solid cylinder, the bottom cone of explosive would "blow outwards."

    Removing this bottom cone of explosive allows the explosive edges outside of it to "blow inwards" as the top gases expand (roughly) "in every direction." The superposition of these competing effects creates a downwards jet (and a toroidal smoke vortex also).

  • @nathanwilefrazier Or think of it this way (a little gross but oh well) - it's like squeezing a zit: The top of the charge (and metal conical liner) is the zit juice while the sides around the conical liner are the "fingers pressing inwards on the sides of the zit." The result? KA-POW!

  • You can actually do the same thing with a wine bottle. Not as effective as steel though.

  • @Fefou1234 copper is also really really good for this purpose

  • alta wie ne panzerfaust rofl

  • thats how hollow charges like RPG works , the explosion of the warhead of the RPG hardly scratch the surface of the Tank , but the hollow shaped cone at the end of the warhead make the explosion not perfectly symmetric but large portion of the high velocity 3000 degrees hot gas of the explosion pour from the front of the exploding warhead like a fountain and burn a hole through the armor steel and raise the heat to lethal degrees inside causing injuries or deaths or ammo or fuel ignition

  • nice when u want to plant a tree and won't dig the hole...

  • @midgetman2142 creativity has no limit

  • chil

  • Thats alot of pe4 in that box, wouldnt want to put a detonator in that

  • I actualy think that would be quite cool

  • yeah cool but real dangerous and itd make a very big hole in something

  • yeah awsome right

  • yeah that looks like 20 pounds or so

  • Abadd0n's book is a book of stupid.

  • So amazing, and it was the Germans idea to use this kind of weapons.

  • uhmmm actually this type of blasting was done by miners for years before the war ,,, and the swedes and fins did a neet trick they would remove the shell from a rifle shell turn it around and they could shoot into tanks ,,, with a rifle

  • Is the cone made of a special form of metal (ie. copper, silver, etc..)? Or will any cone shaped metal/steel item work for this?

  • copper

  • Thanx

  • actually, you could use any thing, I've seen wine glasses used as liners

  • really? Never thought that glass would work for this, lol.

  • Actually even air works. Just make it in the proper shape and due to a thing called "Munroe effect" it will blast a hole. The thing is that using metal liners has better performance. The best to use is actually tungsten, gold, DU, platinum or any other dense metal. Modern armor packages are easily defeated by these new liners (although they are relatively immune to older copper liner based charges).

  • most effective weapon used by the resistance in iraq.

  • I love C-4

  • HEY! SOMEONE ANWSER ME FAST, the C-4 with cooper liner should work better? The PE4 had more plasticizer than C-4( C-4: ±5% PE4- ±10%) these explosives are RDX based explosives, so C4 had something like 91%+ of RDX and PE4 something like 83+%RDX, that concludes the C-4 is more "pure" and powerful than PE4 ( france-made explosive)

    C-4 detonation velocity : 8040 m/s, it is easly hand-moldable, it should work in anti-tank rockets (shaped-charge warhead rockets)?

    RDX Detonation velocity : 8740 m/s

  • that isnt a question its a statement

  • write this guy 'nitrofiz'(look up 1200 grams apan vs rock on youtube also)...he helps and knows his shit!

  • I wouldnt go so far to trust someone who blows up 1200g of tatp because that is not risky its simply dumb

  • this has been used by pretty much every military force since world war 2, this video isn't teaching any of our "enemies" anything useful.

  • still sucks that his friend died, but yeah you have a point this is nothing new...

  • @pyro3rg very true any kid could buld this

  • Shaped charges have been around since before WWII and the information thereof is property of the public domain... Meaning ANYONE can read about their construction. Even you- and trust me, terrorists don't go to youtube to learn about explosives.

  • Lucky!!! i wants some PE4

    Also, if you were to make a similar shaped charge with aluminum, could you have similar effects?

  • NOPE... its better use cooper cuz coper easly melt downt the armor.. and blabla bla, its is better cooper liner ownsz

  • isn't this the krakatoa?

  • no but the krakatoa follows the same principle a shaped charge needs a stand off in order to work at its top efficiency. the krakatoa does not as seen on future weapons the launched their copper slug many yards and penetrated their target. i believe that this is caused by the angle at which the cone is molded notice that this charge in the video is more of an acute angle whereas the krakatoa is more obtuse, but since they follow the same principles they are one of th same so yea technically itis

  • IED is what those damned taleban iraqis use

  • Why couldn't they just make bullets like this? That could fire out of like a grenade tube of a M16. It doesn't need to go through 6 inches of armor.. but if it could crack the block of a car that would be nice.

  • The M433 HEDP 40mm grenade is a shaped charge.

  • What exactly does the detonator do? The thing that's attached to the wires- does it provide the heat to start the explosion?

    Because the video says that the C4 explosive is insensitive to shock, what does that thing with the wires actually do?

  • It provides an electric pulse.

  • So, would static electricity be a risk near plastic explosives?

  • Maybe. Search for "static"· here:

    w w w . makezine . com / extras / 126 . html

  • German electric blasting caps come with the leads separate. Why? They believe a closed loop antenna is more hazardous, as we feel the dipole to be.

  • haha

  • Both wrong. The detonator is a different explosive, used to set off the more powerful, less sensitive one.

  • A detonator is a small but powerfull explosive device. Yes, C-4 is not sensitive to shock (which makes it good to handle) thats what the detonator is for: It provides the shock able to "detonate" the explosive. It's not "electrisity," it is a compression wave. Google detonation velosity. C-4 needs a verry powerfull shock to detonate (NOT deflagrate - which is what gunpowder does) If you light C-4 on fire it simply burns like a cigerette. It's safty AND power is what makes C-4 military worthy.

  • The wires are used to detonate the "detonator." Using electrisity to heat a filiment inside the detonator so that it can detonate the payload at a safe distance.

  • Insensitive to shock like if you drop it on the floor, but not to shock like a small blast

  • @nuclearrabbit

    finally someone with knowledge on Youtube!

  • the kick or the recoil of the gun would be very great. you wouldn't want to be shooting it

    But maybe on a humvee

  • It´s called a bazooka or panzerfaust and it was used in WWII

  • @razorx71 what about a grenade that would upon impact release a midget carrying a battery powered drill ?

    AKA : grenade-launcher propeled battery-powered-electric-drill­-waving-midget in a ballistic device TM

  • @razorx71 because i think that bullets are illegal because are considered inhuman, i think its stupid because a bullet is to kill no matter what shape or effects it has

  • @razorx71 cuz the forse of that thing going of (if the tube holdes) would make ur arm flying

  • @razorx71 look up the raufoss mk211 50cal round. it is the main round in the US army used in 50cals aside from the 50bmg.

  • This video shuld be called "I can IED and so can you!" LoL

    Soon Martha Stewart will be covering this. Should be handy when the chinese come to take over the country they already bought ^_^ lol

  • I LIKE

  • isn't this basically an IED?

  • Uhh no. More like an IED is basically an explosive. lol.

  • No this is a base for an EFP.

    You just get the cylinder of bigger diameter and close one side.

    The side they have closed with a plastic cone is to be subsituted with a copper cone.

    And there you go - an EFP.

    IED is just some explosives surrounded by metal parts all put into a metal case.

  • well basicly yeah

  • I .E.D.=improvised explosive device so it kinda is.

    shaped charges are used in RPG's Also and maybe even more things

  • Shaped charges are used for a number of applications. Probably one of the more common are cutters used in building demo to slice through steel support columns. Its just simply focusing more energy in 1 direction, instead of it going in all directions easily... can't be much simpler.

  • true but the charge velocity is also important otherwise you could use black powder.

  • also density and a lot of other factors come into it

  • idk if that would work

  • Yes they know how it works ffs! And I write as a physics student. It's not quantum physics, it's basic fucking dynamics!

  • Yes, it IS dynamics. Even I can CALCULATE how and why it happens in a year or so. I just need to get my course in thermodynamics over with.

    The process is very sinple... it's not quantum physics as I said and it is fully understood!

  • tell more about your book.

  • wow abbad trying to sound smart?

    quantum physics isn't even remotely close to anything in this video

  • its just fast traveling material having enough kinetic energy to penetrate steel

    not any hard physics at all

    u could just as well use a rail gun to speed smth up like than and it will penetrate the steel the same way

  • Wonder if this would work with t6 alloy instead of copper?

  • what show is this from?

  • probly futurewepons

  • Im a noob to this, but i heard somewhere that they dont know exactly HOW it works, just that it works. THey dont know the exact science behind it or something. Can someone clarify this or shed some more light on it for me? If there are similar comments i apologize i didint read many of them.

  • See the post below yours.

    h tt p:// en. wikipedia. org/ wiki/Munroe_effect

  • a nuke relies on the shaped charges surrounding it for detonation. the correct term is the Munro effect, although 2 guys, Miznay and Schardin also devleoped a similar concept

  • shaped charges penetrate steel by a combination extreme heat and brute force and hyper velocity. abrams tank armor is part ceramic, the ceramic cant be melted by any small to medium sized warheads. btw nuclear weapons cant be used in shaped charges.

  • Could this by applied to nuclear devices? Would be the ultimate bunker buster.

  • lol

  • I just read that the largest shaped charge tested penetrate 3.4 METERS of high strength armor steel. Instead of copper they used molybdenum. I don't think an Abrams could hold up to that. These "slug" travels SO fast, it treats anything, even solid steel or reactive armor as if it were a liquid. "While the concept of a metal surface being squeezed forward may seem relatively straightforward, the physics of shaped charges is very complex and even today is not completely understood."

  • this is the Munroe effect.

  • once again this tech aint new, we use it for at4s and tow missle systems, its meant to go through tank armor... look up monroe effect on google lol

  • lol it's basic dynamics. It's not quantum physics you know.

  • then would you care explain to me how it works without referring to the Monroe effect?

  • OK: the copper cone / shaped charge is being blasted inward out to form a dense & high velocity projectile that penetrates armour. Simple.

    The effect is being used in LAWs and other anti-tank weapons.

  • what you say is true, but I will stand up to this; "While the concept of a metal surface being squeezed forward may seem relatively straightforward, the physics of shaped charges is very complex and even today is not completely understood." I know about the dence and high speed projectile, but why does it form, or how is it that it stays in a perfect strait line until it penetrates?

  • I say again: it's basic dynamics and it IS fully understood. Have you had any physics courses? It's not so complex... it's basically just calculating energies, forces and velocities. Hell, even I'm going to be calculating things way more complex than this (I'm doing my first year in physics at Uni).

    Now I don't know how to give a perfect phyical description of the event, but it's not a mystery you know. Just because you don't understand the physics behind it doesn't mean everyone else don't.

  • its not melted metal, just high pressure makes it liguid like, but not melt.

  • it actualy does melt from the friction of being inverted so fast

  • What is the point in wearing helmets I could understand goggles but...

  • haha, same here I have to wear them when setting up a stage funny thing is that if any one of the pieces of equipment that you are flying falls on you a hard hat aint gona do shit! lol

  • Thats what i was thinking! lol :D

  • falling shit. duh.

  • Falling shit wtf. Look at KaylinJH's comment he 100% right a flying/falling piece of metal is no match for a piece hard plastic on your head. And if there up on a hill about 30 metres away how the hell is there going to be falling "shit" coming at you from above and there isn't even a sealed top on the charge so the shrapnel would go outwards.

  • Whats your point wonkydoodle?

    You say its wrong and then go on to describe the principle points of armor penitration, Based on what this vid just showed?

  • My point?

    That there are shaped charges like the ones used in anti tank weapons, that can penetrate explosivly reactive armor, which is something soylentgreenb has got wrong.

    You got a problem with that?

  • Lovely.

    Used to be part of every soldier's training. Great stuff for cooking foods in cans, but, never, oh never, stomp on the fire to put it out!

    This provides a nice explanation to the wtc damaged cars on 911. They just used a little too much.

  • an online training for Al Qaida here? this is a threat to national security!

  • i do not agree with that, i think that if u had this size of sience u can think this out !

    (but i still get ure point !)

  • Ur government really is messing with ur minds, it even has u ppl parroting their ...jeez

    this isnt anything new or groundbreaking...the know-how has been available for donkey years...and yes, it ISNT rocket science.

    Anyhow, somehow I doubt YouTube will be the place anyone would come looking for this..

  • I know they give wonderfull new names to things that have been around for years! EFP = shaped charge, VBIED = car bomb and IED = crude landmine. They give them fancy names to make them sound "high tech" when really they are very low tech weapons.

  • yet, VERY effective

  • LOL doesn't matter if their low tech, they can punch holes through M1A1 tanks, rip off any kind of armor.. the effectivness is unrefutable

    it keeps the US troops death toll up and keeps the fear factor present within the soldiers

  • KaylinJH:

    your comment is pitiful

  • how so? please enlighten me. Or is it that the truth hurts maybe?

  • how so? let me tell you

    what matters if their low tech huh!?

    they can punch holes through M1A1 tanks, rip off any kind of armor.. go in one side and out the other killing whatever is in between

    the effectivness is unrefutable

    it keeps the US troops death toll up and keeps the fear factor present within the soldiers

    The weapon that has blown the confidence of the american troops more than any other

    truth really hurts doesnt it?

  • I think the shaped charge concept is called the "Monroe Effect" If someone knows how to make a shaped charge or a platter charge you can really do some damage. Any fool can make a bomb, but a real pro makes it effective every time.

  • This is why most modern antitank warheads have tandem shaped charges.The first one fires and trips off the reactive armour,the second one fires a fraction of a second later and penetrates the now unprotected armour.The armour of WW2 you so ignorantly referred to is actually just regular armour but it is sloped to possibly deflect EFP jets.All the steel in the world will always lose to all the explosives in the world.Also the need for tandem is not absolute a really large shaped charge will do.

  • how so? let me tell you

    what matters if their low tech huh!?

    they can punch holes through M1A1 tanks, rip off any kind of armor.. go in one side and out the other killing whatever is in between

    the effectivness is unrefutable

    truth really hurts doesnt it?

  • yea so low tech that you can make one out of the bottom of a soda can. now thats scary even though it wont penetrate as much as the copper cone.

  • yea scary indeed

    Sergeant Jason Vega, a US commander was quoted saying that about EFP's:

    "every EFP that goes off kills something like 2.5 soldiers, thats the only thing Im really afraid of out here in Iraq"

  • they can't pay internet.. too stupid

  • al qaeda get its bombs from the CIA .

  • What?!

  • 9/11 Was An Inside Job.

  • thats what she said

  • Question1981.... your mom was an inside job

  • whooooooooooooooooo

  • yes anything can be compressed to an extent because there is some space between atoms but for all practical applications liquids are not compressible

  • I second that. If it were possible, we wouldn't need to use massive tankers to ship fuel etc, we could compress it.

  • "...for all practical applications liquids are not compressible."

    Look at plutonium based nukes to see what it actually takes to get significant compression of solid matter.

  • what derek? of course you can compress fluids! just google ''compressed liquid'' and your first hit will inform you.

  • yes yes this is what USA forces are facing in IRAQ ied and this thing there is nor armour this thing wont penetrate ....

  • They are creating active armor that can defeat it, but its really expensive. One way to defeat it is to have two plates of metal with an insulator between them. The plates are charged to a very high charge and if anything pierces them it will complete the circuit creating a huge arc. The arc will vaporize the already liquid hot chaped charge projectile. Its dead simple and cheap too. Easy modification to any vehicle.

  • active armour has been around for a long time. they are just putting it on more vehicles, like strykers or bradleys.

    Anyhow. Stop the war.

  • "yes yes this is what USA forces are facing in IRAQ ied and this thing there is nor armour this thing wont penetrate ...."

    Explosively formed penetrators aren't like regular shape charges. Regular shaped charges like you get in a regular anti tank weapon are defeated by reactive armor.

  • That is so wrong.

    Look at the RPG-29. Its an anti tank rpg and it CAN get through Explosice Reactive Armor.

    Need an example: look at how it was used against the Merkava tank in Israels invasion of Lebanon. It has also penetrated amror on a Challenger II tank in S Iraq.

  • wrong! well partially anyway...a molten jet of coppe/metal isn't the main thing that punches a hole in targets...it's actually got more to do with the monroe effect.

    look it up!

  • To put it simply, a fluid cannot be compressed. So if it is a fluid projectile it actually is harder than the armor upon impact. Pretty crazy.

  • what show is this

  • ballistics investigated i believe.

  • k thx

  • "Ask the Russians what they did with Saddam's WMDs"?! LOL, what the hell are you talking about? Talk about "delusional"...

    The reason Saddam's WMDs were never found was because they never existed. Pro-Israel agents in the US government (Paul Wolfowitz, Richard Perle, Douglas Feith), with the cooperation of the Bush administration, falsified the intelligence about Saddam's weapons in order to gain public support for an invasion that was only meant to benefit Israel.

  • this is quite cool

  • so that's how bombs costing less than a US$100 to make end up destroying, for example, a US$25 million M-1 tank in Iraq.

    Who needs high-tech when low-tech ingenuity is also enough ?

  • low-tech, and yet they still go to iran for there shape charges.. Shows how ignorant those rag bags can be.

  • They're not getting them from Iran. That's a US government lie intended to justify a future attack on Iran. Just like the lie about Saddam's WMDs.

  • live free, buy a t-shirt, stop anal leakage:

  • One merciless bomb. Still i stick with pure water and some electricity for one. (Not for 'drilling' inch thick steel plates of course.) Cheers!
