Alternative source of Ammonium Nitrate?

[Scappe]

Once, looking through a first aid kit, I found an instant cold pack. There were 2 ingredients on the bag: water and Ammonium Nitrate. What's more was that the yield of AN was pretty high, so I don't understand why nobody's tried using these over the involved process of taking prills from bags of fertilizer. Cold packs aren't that expensive, I've found them in cases of 24 at $0.72 a bag, but I'm also sure that I'm not the first person to have noticed this, so I just want to know what flaw in (or, more optimistically, affirmation of) my logic has led me to this conclusion, because I feel like there's a hole somewhere in my thought process.

Oops...

You have failed to UTFSE. Cold packs are a well known source of ammonium nitrate.

Use the search engine before you post.

The reason we ask that noobs not start new threads is because they often fail to search before posting and in turn start topics which have already been discussed to death before. :rolleyes:

Consider this your first warning, Scrappe.
