^your chem course lets you use sodium? Thats extremely dangerous. What country do you live in? In australia you MUST be a qualified chemist or other scientific career and have alot of paper work to get it.
im in a chem course where i have to build a device that uses 10 grams of sodium to blow through 1/4 inch thick piece of plywood. Would a shaped charge be the way to go? Im not sure if the sodium gets hot enough to melt a metal cone considering its just raw sodium and water.
Its not so much the shaped charge. The copper plate liquifies and then forms a slug due to aerodynamic forces. The slug self forges as it goes thru the air and becomes very hard. And its travelling at silly velocity. They did this with the Skeet munition back in the eighties. High explosives frizzbies!
the TALIBAN use this weapon, though they call this an EFP. theres NOTHING right now that the ARMY has that can stop this...instead of making a show called FUTURE weapons,...HOW ABOUT FUTURE ARMOR!>...
Yes. Krakatoa/Krakatau is the volcano that was located in Sunda Strait, between Java and Sumatra. It was disapeared as the result of it's blast. Now, a small volcano is emerging from bottom of the sea, and Indonesian call it Anak Krakatau (Child of Krakatoa).

Actually, IED's rarely have a shaped charge. That's one of the reason why they're called "Improvised" Explosive Device. Most of the time they're made out of old artillery shells.
wow seriously, a shaped charge by itself, thats supposed to be a "break through"? OMG imagine if you could launch it in some kind of rocket! OMG! and an inch of steel holy shit! that would be great prior to depleted uranium and ceramic armour! not to mention every APC with armour thicker than an inch and lined with kevlar, i cant make this any more sarcastic!!!
While the basics are still the same, shaped charges have come a long way since the Panzerfaust. Also, that thing up there is more than capable of penetrating the side armour of an M1A2. Luckily, it's too heavy to be used in an RPG. A man portable missile on the other hand...
This thing is not really like a usual shaped charge like in WWII. If I am not totally mistaken it is rather an EFP charge, which can be seen, since the copper cone has a much larger opening angle than a HEAT-charge.
This doesn't create a jet of copper, it creates a bullet, and no, It doesn't mealt through the Plate, is just moves very fast, (1.5-2km/s), giving the copper slug a huge amount of kinetic energy. Far more than any normal bullet (x'ept for HEAT-charges or sucaliber ammo)

U think u smart?And what the hell means "WAHT BEGIN THIS??"Try to go to school sometime and learn a language that is even better than your!
uhm, isnt the krakatoa already like a gun? the plastic cylinder is the barrel and the copper is the bullet the plastic explosive is the gunpowder, so its basically a miniature cannon
This is more of a shaped-charge device. An IED is like a fuse straped to an ammo box full of nails and gunpwder. Hence the name, IMPROVISED explosive device. This is a PREPARED explosive decive. HA
by propelling the copper with an explosion you get great speed, several times that of non-explosive grenades. at such high speeds and temperatures the metal behaves as a liquid.
The jet of molten copper carries on into the ship and causes secondary damage, imagine it placed near vital equipment, also in the video they mention placing more than one per a ship.
The reason most people here are underwelmed(sp) is because this is a weapon without a delivery system....imagine it as the bullet, what we need to see now is the rifle that fires it as it were.
I've seen footage of this device or something very much like it placed on a robot sentry that hides and waits for tanks/trucks to pass close then fires the weapon at it.... it was very very effective.
It can be spelled three ways, either Krakatoa, Krakatau or Krakatao. I also believe the weapon was developed by the British. Thanks for being stupid though. It mush be fun having the IQ of plant life Knigge46.
Damn, they call it "Future weapons". Devices of such type had been invented more than 40 years ago. They are in service in many armies for dozens of years.
the insurgents are using those as we speak, compliments of Iran. we may have all these new weapons, but we're letting those nations that REALLY ARE evil push us around. Iran, China, Russia.
U little us motherfucker wake up!!! u call iran china and russia evil? are u ok or are u just such idiot??? watch out your words!! u call these countries evil? but ur fucking country has killed more civilians during the last 15 years than they did since the second world war!!! stupid us kids!!! nothing else to add.
when the hell did we call russia evil? during the cold war?! US doesnt think of Russia as evil any more, not since the wall fell. since china never realy got a chance to kill civilians during WW2 and iran wasnt in WW2, u must mean that russia killed fewer civilians in WW2 than America did in the last 15 years. that is bullshit, the first ones into Berlin were the russians (by a couple of hours), and the russians hated the germans more than anyone can understand.
so, think about a hundreds angry, pissed off russians going into the capital of the people they would do anything to kill. they killed almost everone and burned almost everything (just like the germans did to them earlier). oh and they killed thousands and thousands of german POW just before the war ended for more revenge. one final note, america hasnt been the one that has killed so many civilians in Iraq, the taliban have with there bomb and fear tactics.
the americans on youtube do not show the point of view of all americans, because our country allows everyo one to have their our own opinions, unlike the shit hole u most likely live in.
well it uses the same principle as a HEAT(High Explosive Anti Tank) weapon, the only difference is the shaped charge's liner angle is very small so instead of having a small standoff distance for optimal jet penetration it forms a copper projectile slower than a jet but with a much much further standoff distance from the charge.
