So far Wallgreens is the only chain store I've found that carries ammonium nitrate Cold Packs. They have a case of 8 cold packs for $9.99. At 1/4 lb per pack (water bags
removed) that's 2 lbs for ten bucks. Not bad. And you could order them online if you
wanted to.

What kind of fertilizer is "Ammonium Nitrate"found in??

I must be a different kind of person. Instead of having to worry about all these bomb warnings I was thinking more of nitrous oxide (laughing gas). That's how I got here.

you can get ammonium nitrate by mixing ammonium (from laundry stuff), nitric acid (good luck on getting this, I can't seem to find any), and sulfuric acid. Mix them all together,then pour it through a filter. you will now left over with ammonium nitrate with a little sulfur impurity. If you want pure ammonium nitrate, dissolve the mixture of ammonium nitrate/sulfur in methanol (Heet antifreeze/water remover, or methyl alcohol). Pour that trough a filter, the sulfur isn't soluble in Heet, so only the ammonium nitrate gets through. Let that evaporate, and there you are.
I think it is much easier to get an ice pack or fertilizer, though. oh well. A friend of mine somehow obtained ammonium nitrate (i'll ask him sometime). Hope i helped!

P.S. If you are planning to make a bomb, mix ammonium nitrate with alcohol. Alternatively, you can mix ammonium nitrate and potassium chloride (salt substitute) to form saltpeter (potassium nitrate), which is much more explosive.
P.P.S. Please be careful. Nitric acid and sulfuric acid are very corrosive, and bombs are very dangerous. Try not to blow your fingers off!

am i the only one really concerned with this topic?????????

Besides using small white "balls" taken out of 'one use' instant cold packs, which can be found in random drug stores(w-mart doesn't carry them) This youtube video is the easiest way I have found to make it with cheap and easy to find ingredients. I would recommend using a hair dryer on low or drying in a large flat pan (over very very low heat) instead of waiting 1-2 days as instructed in video. Can be done in less than a hour or so depending how u "dry"(allow ingredients to evaporate). U will understand what I'm talking about after watching the video. Here's the link: http://www.youtube.com/watch?v=w2IG49Nw1Fo (

you can get about a little less than a cup if you buy an instant cold pack

You can just go and buy it, just like any other fertilizers, how ever if they think your doing something illegal with it, they will report you, which they are legally required to do in lots of areas, and or not sell it to you or both, and yes they will question you if your just looking for one bag of it ..And can you afford, use a ton of it ?? Most big box stores don't carry it, you need to go some where dealing with agriculture, but keep this in mind, in that business every one knows every one else and if they don't know you it might get interesting....

> how do you make it? Ammonium nitrate can be prepared from Air and Water. See the "Haber Bosch" processes for details, but essentially you split the water into hydrogen and oxygen, react the hydrogen with atmospheric nitrogen to make ammonia, oxidize some of the ammonia to nitric acid using the oxygen, and then react the ammonia and the nitric acid to get your ammonium nitrate (outlaw THOSE ingredients why don't you BATF! Hah!) Commercially, the hydrogen will come from natural gas rather than water, but that's just cause it's cheaper. (rather exotic pressures, temperatures, and catalysts are required. This isn't really something you can do at home...)
