I'm going to throw together a few short guides for pyro related stuff in the coming weeks, and I'm just wondering what the community wants to see. The goal is to stay away from k3wl stuff like sparkler bombs and soda bottle pressure devices, but I don't want to get too advanced and bore most of the readers to death with things they'll be unlikely to ever attempt themselves. That's why I'm asking.
On the table right now is an OTC synthesis of ETN, perhaps a safe method for manufacturing and storing HMTD, and of course a synthesis for a safer primary like silver acetylide as well. I'm also considering a basic writeup on oxygen/fuel balloon explosives, covering stoichiometry and optimum fueling/ignition techniques. A friend of mine on the other side of the country did a lot of testing with such devices in summer 2008, and we discovered a lot of new info that isn't (To my knowledge) found anywhere else on the internet.
A guide to mixing flash powder and perhaps small scale black powder manufacture is also in order, methinks.
Lettt meeee knowww...

BB is soon to be my favorite board.
I would like to see some instructions on making a bomb or something explosive using tons of different fireworks.
Bromine is very easy to make from stuff you can buy at the store, but unfortunately nitrogen tribromide is virtually impossible to make.
Unlike with nitrogen trichloride or "nitrogen triiodide", simply reacting ammonia and bromine will not make anything that is explosive.
This may be somewhat surprising to you, since chlorine, bromine, and iodine are all in the same column on the periodic table, and bromine is in the middle!
To make iodine, simply mix potassium iodide with dilute hydrogen peroxide, with a tiny bit of acid. Elemental iodine reacts with ammonia to form a spongy purplish- crystal-like substance that explodes with a poof, making a little purple cloud of foul iodine vapor!
The slightest little disturbance will set it off, even trying to lift the substance off the paper. Not really useful for anything, except as a novelty. More accurate to call it "ammonia-triiodine nitride" adduct, but does not really matter. Everyone knows what you mean when you say "nitrogen triiodide".
Dissolve a tiny quantity of the blackish purple-colored iodine into a little cup a quarter full of ammonia. Be sure to put a coffee filter paper in pressed against the bottom before the iodine is added.
After the two have been mixed, place it outside on a warm night (out of sunlight) to allow the ammonia to all evaporate out. With the filter paper still wet, remove it (you should see a purplish pasty substance on it). Allow it to dry for 3-4 hours. Do not be impatient.
After it has dried, the slightest touch from a feather (or long wooden stick) should be enough to set it off.
Do not try to store it, it is likely to explode by itself, sending out an iodine vapor cloud that will stain everything around it.
Could you store it if you keep it damp/wet with ammonia?
do not really know the answer to that question. think eventually it would degrade over time.
some people have kept the stuff for over a month, kept moist in sealed little cylindrical film containers.
It is not really the type of thing you would want to store. Remember, it can still explode when moist, keeping it under water does not eliminate the danger of explosion. These types of things a very unpredictable. What might seem completely useless, could later spontaneously detonate after being left in storage. That is why only very small amounts are ever made.
Nitrogen triiodide is one of the most sensitive explosives, the only one I am aware that is more sensitive is nitrogen trichloride.
