Hey, is ammonium nitrate fertilizer a watched substance yet?

You need something to start the detonation. It's back to nitrates and fulminates. (Mercury fulminate is the thing to weed out idiots -- easy to make, sensitive as hell, and releases mercury, which of course is neurotoxic.)

Blackpowder works fine, is easy to make from scratch. You get sulpher from the garden store, charcoal is easily made or bought, and potassium nitrate is easily extracted from manure, or just save up your piss for awhile. And all you need to set off black powerder is a fuse or a match.
