Hi all,
I know I'm probably opening up an old thread but I couldn't find a
FAQ for this group (although I didn't look very hard), so please don't tell
me to RTFM or anything.
I need a recipe for touch powder made from fairly common ingredients.
Nothing fancy just the usual volatile powder that makes a small explosion
under impact.
You may be looking for a recipe to make nitrogen triiodide, a very
POWERFUL and DANGEROUS compound which is feasible to make in
tiny quantities if you know what you're doing and don't do
anything *stupid* with it. The recipe is in the FAQ which,
last time i checked (about 30 secs ago), was the very first
article in the newsgroup titled rec.pyrotechnics FAQ. Have fun
but b careful..

What happens if you use very large amounts?

You cannot. It will not permit you to do so.

Best thing about this formula you are wanting to make is,,, Just forget it and find a safer formula for your needs.

The strange thing about this explosive is that when it goes off it doesn't all go off and very small amounts of unexploded material is spread over several square feet so that if you go over that area with a broom you can hear crackle sounds as very small quantities are set off by the friction of the broom.I would expect that an explosive of this extreme sensitivity would all go off at one time but it doesn't.I never have heard a good explanation of this phenomena.

Where have you ever encountered any item that behaves perfectly as theory would predict? If only the WiZ were still alive to comment!

It goes off when it feels like it.

That's the only consistent explanation for its behavior.
Detonation at whim.

Some 40 years ago, when I last made some of this stuff, I observed
it going off in the bottom of a beaker full of water. *Bloop!*
Why is there water splashed out onto my bookshelf? Watched for
a minute, then again, *bloop!*, more water on the bookshelf.

"Stable when wet", yeah, riiiight.
