ANFO

[7eleven mafia]

ok ive tryed making the ANFO explosive and i failed miserably and all it did was burn, now i figured out that ever since the oklahoma city bombing they have been putting a flame retardent chemical on the ammonium nitrate, now how would i get rid of that chemical and how do i make it exactly?

[torcher]

first thing is you dont just light ANFO. it takes a blasting cap to set it off. ANFO isnt really worth the little bit of trouble unless you're going to make a large batch. but as for exact specs...http://img.photobucket.com/albums/v328/torchersapyro/216.gif

I think the boiling method would be best. Separate out anything that is obviously not AN. then boil the rest. its shouldn't bubble but simmer. When you pass the boiling point of everything lower than your AN, thats the purest you'll ever get without lab equipment. For blasting caps. use Acetone Peroxide and aluminum tube. Most other blasting cap materials will explode you pretty easily due to unwanted reactions.

I'll upload it to my 4shared account if your having trouble finding it.

the problem is that idk what the chemical is so if i were to boil it i dont know what sort of toxic fumes would come of it if any

[torcher]

ok, i doubt they would put a flame retardant chemical on it since it is used for farming and that setting it on fire doesnt do shit. used in explosives, ammonium nitrate is set of with a blasting cap not just lit with a lighter or torch.

A blasting cap is a small explosive device generally used to detonate a larger, more powerful explosive

wikipedia is great too.

ok thx

Blasting Caps are used heavily in Industrial and Military use in regards to High Explosives. There are a few types out and about there...

It should be able to help you. Good luck...

Tim McVeigh used an ANFO or more specifically ANNM [Ammonium Nitrate/Nitro Methane] when blowing up the Murrah building in OKC. He stole Industrial Non-Electric Blasting Caps from a mine and used them to detonate the ANNM.

Interesting video.

Not to make you feel silly or anything... but if you "caught it on fire" then you obviously don't know the nature of the beast.

You have to mix AN with the proper amount of sensatizer. AN is extremely stable... stable enough for me to keep under my bed...so stable infact that in mining operations large boosters of MORE POWERFUL explosives are used to make sure that it will all go off. ANFO is usually mixed and then constantly agitated to keep the sensatizer (usually kerosene) and AN properly mixed. ANFO is picky.. you can dead press the stuff... meaning that if your charge isnt large enough or if the mixture is compressed instead of being left fluffy, the blast wave wont propagate far enough into the rest of the charge to set it off. if youre trying to get a hand full of the stuff to detonate, you'd be better off not doing it. because that isn;t enough to even go off. I don't know the exact amount, but i believe that you need a lb or more to reliably detonate it instead of the stuff just being blown around. it's that stable. also, a lb will be heard for miles.. so if youre in an area where people may call the cops... then maybe you shouldn't do it.

I'll put it to you like this. one lb is 454 grams. an ammonium nitrate mixture was set off that was about 250 grams and under 3 feet of water. it was heard a mile away. so just think about how far near twice that amount would be heard if it was set off in an open area. not to burst your bubble or anything, just thought i'd let ya know if you didn't already.

also, line of sight is a bad thing. ANFO detonates at around 4500 meters a second i believe. compare that to 2300 feet a second for an m16 bullet. (the bullet may go faster or slower, i was just throwing it there for comparrison) That means that if the explosion throws any small rocks or anything they'll be moving at roughly 6.5 times faster than an m16 bullet and it would definately damage things... like you if you happaned to be watching..

ok thx i think i had like over a pound because i got the a ammonium nitrate from cold packs from my local drug store, but shit i didnt know that it would be that bad.

[THErAPIST]

i didn't figure that you had any clue about how loud it could be, or just how bad things can go under the perfect circumstances. just trying to make people aware :ahso:

As stated above you should definitely add a sensitizer to it..kerosene IS the most common, but I'm pretty sure nitromethane gives you a more sensitive mixture..it's also much more expensive.

To reliably detonate I would say AT LEAST 100g, and even then it probably won't work very well..you probably won't get a full detonation. What I would do is get a cap (about 2-2.5g worth) of HMTD or AP, preferably HMTD set in a straw. Set this into a booster of 15-30g (yes that much!) of APAN or HMTD/AN. An alternative that I prefer by a wide margin is an ETN booster.

If you want to get the maximum performance possible I would say an HMTD cap of 2.5g set in a 25g booster of ETN..at least 250g of AN for a full det.

-Be VERY careful with the caps and boosters, do NOT set the cap and booster with the secondary until just before detonation.-

-This will be heard from VERY far away, as stated earlier, the cops WILL be called if you don't live in a very rural area.

I hate ANFO so this is all I have for ya..if you need help getting NM I can help you.

If I were you I would go ahead and just make some ETN, if you need help with the synth, ask. Sensitize it with Al powder, it's a great explosive for about 1000 reasons.

Nitromethane can be purchased at race tracks, just ask Tim McVeigh!

Try getting it today too.
