Napalm?

[Casper]

Swim was curious, swim saw a video of a person making napalm and used gasolone and petrolium jelly. Cant remember what were the measurments or if person add'd anything else.

Any ideas?

[Day_N_Night]

Simply dissolve chunks of steirophome into a vat that contains Petroleome. After a few chunks are dissolved and you have a gooy sort of thick liquid as a result you shoul dhave what is called "Napalm"

[Th0r]

There's already a thread dedicated to this.

But yes. Best Improvised Napalm I've ever come across was Acetone and Styrofoam. About a 50/50 ratio.

[-=HeX=-]

Such NAPALM mixes are rather fun for use in mollies, however wax candles around a thermite charge is MUCH more fun :)

[death11284]

th0r try diesel fuel (40% vol.) kerosene (20%vol) acetone (40%vol) and throw styrofoam with eggwhites into it
Add KNO3 or sugar and it'll make it "sticky"

It's thin, burns like crazy, sticks to things, and nigh-impossible to put out in that mix.

Thanks for that Death.

I have Diesel Fuel and Acetone but no Kerosene. I'll try it when I can get some Kerosene. It'll also be featured in the PDF.

Good thinking death, i just use to use 60% diesel and 40% 2-stroke fuel. High oil and hydrocarbon content.

Th0r: Parrafin oil IS kerosene and vice versa.

Adding oxidizers is a good idea - today I mixed some KClO3, Gasoline, Oil and sugar with some acetone and styrofoam. Then tossed in some contaminated KNO3 and ignited. Fuck me, it burns FURIOUSLY. As if its ANGRY.

[Th0r]

Yeah, even so it's still hard to get where I'm from.

[Nox (ADVANCED)]

Paraffin has medicinal uses aswell Th0r.

Yuuup it'll do that :)
So just thought I'd say, I switched two words in my post...I meant styrofoam with KNO3 and eggwhites and/or sugar to make it sticky..

[Vallen]

Would adding shotgun powder with Styrofoam be overkill?

I'm guessing it might be good for Molotov's it help to break the bottle if it only cracks.

abortions dont count as medical uses.

Shot gun powder? That's not a real name, if you mean Black or smokeless powder(or dust from the shotgun fairy), no, it wont increase the efficiency at breaking the bottle at all. Have you ever treid to burn wet black powder? exactly.

[death11284]

Theoretically SMOKELESS powder could help distribute the napalm in a Molotov...other things would work much better however: such as flash powder, or an explosive. At this point however it becomes an incendiary dispersion device...

[Vallen]

It is smokeless powder my bad couldn't think of the name.
I got about 8 pounds so a little experimentation won't hurt:firedevil

[death11284]

Yeah just make sure, if it's that recipe I gave, that your not near it when it goes off. If it gets on you, you will get third degree burns, beyond a shadow of a doubt.
It will stick to you, it will be nigh-impossible to put out with either wind or smothering...yeah..just stand faar away :).

[crazy white guy]

This thread is about the formulation of napalm. Jumping to a different topic without elaborating is not good for discussion. When a new substance was brought up, it would mean to add to the liquid/fluid. try to be more clear.

To make it an explosive, you'll have to have a way to make sure all of it ignites. thats easy with things like thermobaric explosives but shit for things like molotov and napalm. It will want to push the fuel away and not ignite it. and even if you have something like pyro stars in the explosive, that will only ignite wherever the star hits unless you have some sort of super flammable, super efficient fuel (not gasoline, acetone, alcohol, naphtha or anything like that)

[death11284]

What advantage would you have trying to ignite a thermobaric explosive versus a conventional explosive? It seems overcomplicated to make something along those lines...you mean like an FAE? I'm really not getting what you mean...

What I meant CWG, and what I think this guy meant, was not to convert it into an explosive...if that was desired, well there are MUCH easier ways. It would more be something explosive or something that will release large amounts of gasses quick (flash powder etc). My thoughts were said compound (NON-thermobaric) contained inside the napalm jelly (you couldn't contain most things in the gasoline..they would dissolve) with only a very thin layer of napalm jelly over it to keep it from the gasoline...

The molotov hits the ground, ignites the gas, ignites the napalm, sets the explosive off. Since the explosive is contained in the jelly it would disperse the jelly at least a little bit. If there was some way to trigger it in the CENTER of the jelly it would be best. Maybe just a smaller glob of jelly would do the trick?

I once tried something similar...potassium chlorate and sulfur powder (I was younger, and more retarded) in the middle of a napalm ball completely dry, completely converted from styrofoam to napalm by the gas...I dropped this into a little bit of gasoline in a wine bottle, made a rag fuse, lit it...

It DID detonate, it DID disperse the napalm, the issue is, the napalm was in VERY tiny bits, and thus went out easier...imagine a breath hitting a candle..on a much larger scale. Long story short only about half the napalm it shot everywhere was actually on fire. This was actually all done in a cul-de-sac so it was extra-stupid...

Also, the issue I implied above happened, it took a few seconds (like 10-15) for the KCLO3 to detonate...a smaller ball or thinned top-layer would probably solve this..


I may have just missed the point of your post completely, if so, my bad.

That's what I meant, Normally i don't mess around with Molotov but I ran out of chemicals to make better explosives. Only a couple more months before I can get more :arms:

[Yafmot]

OK, gang, LISTEN UP! There are many thixotropic incendiaries out there, but the true, original NAPALM, as dropped on the Japanese in close support of allied troops in the Central/South Pacific, was a simple blend of NAPhtha and PALM oil, hence the name, which was obviously a contraction of the two words. The "bombs" were little more than thin-skinned, converted drop tanks. The filler cap was replaced with a fairly slow, but hot burning, fuze designed to ignite the mix as the vessel ruptured at impact, splattering clouds of the stuff on a targeted area.

Of course, pyros are pyros, professional or otherwise, so fairly quickly people started thinking of ways to enhance this or that specific property. The powers that be at various arsenals and elsewhere figured that attempts would be made, and countermeasures undertaken, to extinguish the stuff.

Ha ha! fooled you,Tojo! They put oxidizers in it, usually KNO3. (And Death, I think maybe your overactive imagination DID detonate. I've never tried to det a mix of KNO3 and a Hydrocarbon, but at minimum you'd need a cap. I think what you witnessed was a very rapid deflagration caused by the KNO3 melting into whatever fuel you used very intimately at high temperature. Very different.) The resulting compound was substantially more difficult to extinguish, but didn't "detonate." I have known dozens of fighter pilots who dropped many different marks of "Bomb, Incendiary, Thixotropic, Mil-" etc. A lot of them said they got some huge fireballs off the strikes, but NONE of them ever mentioned observing any shock fronts or condensation waves as a result of these drops.

To this day, ordnance engineers are still farting around with methods of getting it to truly detonate. and what have they found out so far? Only this: If you DO get it to det, very little, if any, of the stuff remains to get splattered on the bad guys. It's all consumed getting the holy VOD up to where the shaock will be useful. You want to hit the bad guys with a concussion that will cave in his lungs & face, shatter his bones and teeth, and destroy his stuff violently and instantly? Smack him with a tub of HE (TNT, Ammonal, Comp-B, Torpex etc). Want to scorch his flesh off to the bone? Splatter him with something gooey, sticky and very flammable and set fire to him. There's very little in between.

As for "Styrofoam," that's a brand name for a structural foam based on polystyrene, but very firm and stiff, with a high compressive strength. And it's way more expensive than the stuff that makes up those cheapo disposable ice chests you see in the liquor store, or floating down the river. That stuff is more properly called "expanded polystyrene," or "bead foam." The manufacturing process is completely different.

This charming little piece of mythological bullshit is likely derived from the fact that the Vietnam-era napalm had a small percentage of raw styrene in it. This is a runny liquid in most industrial uses. ("ABS" stand for Acrylonitrile-Butadiene-Styrene and is , in fact, a useful binder for some pyro comps and PBX formulations.) You can easily obtain a kind of "in between" version of raw styrene (the one used in incendiaries) that's partially polymerized into a kind of syrup. It's used to toughen cheap polyester resins, and can be had at a boatyard, plastics shop, or wherever low grade fiberglass layups are performed. Or look up Tap Plastics online or in the Sacramento phone book.

And that, GREENHORNS, is the story on "Napalm" formulations.

By the way, anybody remember a few years ago when the Navy was trying to dispose of some out-of-spec Napalm, and town after town screamed that they didn't want a trainload of "deadly explosives" rolling through their little towns? What fucking morons! How ignorant can you get? Even the newsies were referring to it as "the deadly, vietnam era explosive." And we expect these sub-Geraldos to collect information for us?

I'd much sooner have a traiload of napalm tankers roll past my house than one propane car. Or something worse, like maybe MAPP gas.

[iceniner]

I like you.

[Raverous]

A Vietnam vet that I know told me they used to chunk soap into a barrel of gasoline and stir until it became a paste-like substance to create crude but effective napalm. I haven't tried it, and I wont but the idea seems sound.

[iceniner]

I've heard about aluminum powder being mixed into napalm to increase the burn heat. I'm interested if this is true. I do know there are 6000 lb slurry bombs but those are FAE rather than incendiary.

[Th0r]

I've also heard the same thing, Iceniner so I would think it was true.

It's definitely worth the experimentation.

[iceniner]

Like Yafmot said above, in one of the best posts I've seen here, there is a tradeoff between explosive power and burn. There's also a tradeoff between burn heat and burn time-- if you get it too hot it might flashburn and lose its sticking/burning power. But yes it would be interesting to experiment with. If I had an asbestos suit, which I don't. I'm not going anywhere near burning liquids.

Hmmmm... a suspension of thermite granules?

[death11284]

Yafmer I think you misread what I wrote KCLO3 not KNO3 sir
It doesn't take a whole lot to set of potassium chlorate and sulfur mixes

Maybe it wasn't a true detonation, but that's not the point, it dispersed it.

[-=HeX=-]

The 'Slurry bomb' is not a FAE... More of a Thermobaric. There IS a difference. All FAE's will have a Thermobaric effect... But not all Thermobarics are FAE's. That is assuming a air-oxidized FAE, and self-oxidizing Thermobaric like the mixes the Soviets had. There are exceptions to the rule though.

Yafmot made one of the best goddamn posts I ever seen on the subject.

Before I do any further, I will admit that Incendiaries are NOT my area. However, FAE/Thermobarics ARE in my field of interest.

Now, recently, we mixed up the polystyrene/gasoline 'goop' with added KNO3 and Mg. Several litres were dispersed using small HE charges. We then made a lovely igniter charge for it - 50g PETN charge with a casing of sintered Al powder, and embedded tubes filled with CuO/Al mix. these tubes were the 'reactive Frags' that ignite when they smack into something.... This was in a gallon of petrol. When detonated, the petrol was dispersed and ignited at multiple points. The sintered Al casing afterburned in the air, adding to the intense heat, and wherever the frags hit was ignited by the suddenly burning thermite, and the Cu slag at several thousand degrees. The entire area went up like THAT (it was a area covered in felled trees we were disposing of). All the 'Napalm' was ignited at once, and the intense heat made relatively short work of the wood.

We could have directly ignited the Napalm, but that would have been 'boring'.

A 'Fun' application of 'Goopy' incendaries is at the beach. 'Draw' something, then put small BP ignitors quickmatched together in the 'goop trail'. It is a rather fun, artistic waste of time :) It is better when you add Sr salts to it... Adds nice colour :D

[Jessie Bains]

Would adding shotgun powder with Styrofoam be overkill?

I'm guessing it might be good for Molotov's it help to break the bottle if it only cracks.

You can't really get the powder wet or it ruins the explosive properties.

[Sudz]

I have yet to see it mentioned here, but how come the use of pine tar or other resin has not been discussed? From my experiences pine tar is one of the stickiest naturally occuring substances I come across on a daily basis

[Saturday]

The beauty of Napalm and of Molotovs is the ability to make both with a variety of readily available incredients. "Napalm" and "Molotov" are like the guerilla versions of culinary terms like cookie and pudding, in that there are the original versions and many many others.

My personal favorite mixture for napalm is standard styrofoam dropped into straight high-octane fuel (89). The ratios don't really matter, because you basically want to saturate the stryfoam with fuel until it is entirely a globular, gel-like substance (napalm). You can use soap instead of styrofoam and kerosene instead of gasoline... many different substitutes.

For Molotovs, I like to just tape a sparkler to the outside of a completely filled glass bottle, so that it will absolutely not ignite until the glass breaks. Often times, the biggest mishap with homeade combustibles is that they explode prematurely, or with Molotovs, they drip fuel on themselves and set the back of their head on fire when they are throwing it.

[neffy]

Might take a lot of sap for any appreciable amount of fuel and besides that it may complex out of solution. Interesting idea though. You should experiment.

[neffy]

The military has optimized this decades ago with easily acquired gelling agents.

(naphthenic and palmitic acids). - wiki.

Hence the name, I suppose :-) It's surprising how many people don't know how it originated. I didn't either, until quite recently. One of those "oh yeah, makes sense now!" moments.

[Sudz]

Alot of sap is no problem due to the fact I live on nothing but a planted pine lot. Does anyone have any suggestions or predictions?

[Dutch Legend]

Why do you actually need napalm?

[-=HeX=-]

To fucking burn things.
Why else?!

[Sudz]

Or because I said so. Or just cuz. Just because. The list goes on. My reason is extreme boredom
