Orangekid, that's Nitrogen tri-iodide, and it's one of the most sensitive compounds that exists. An extremely gentle touch with a feather will set it off. Decent sized piles will ignite merely by their own weight. Not to mention it makes purple smoke.

Let's stay on the spring powered ones, though, to prevent a topic lock.

um, actualy, it's amonium-tri-iodide

Both are actual compounds... of which I think NI3 is the more powerfull.
That being said, it's not NI3 or NH4I3; that would be too sensitive. It might be silver fulminate, which is what they put in bang-snaps.

Here comes DR...

clarification, i was asking out of curiosity, and nobody here is dumb enough to make it (or has the materials... taking chem is determining my major, i refuse to go through that) and since it was brought up about a novelty noise maker, not a "commercial and/or homemade pyrotechnic" or "firework" it should be ok.

There are various touch explosives in use, and all of them are very deadly to make, which is why they make the Silver Fulminate in Labor camps in mexico, since large quantities are so deadly and dangerous. I think the one he means are the ones with springs in them.
