And if nitrogen tri-iodide is anything like ammonium iodide, it is not a
thing to keep around in quantity. In college we called ammonium iodide
"fly dynamite" -- meaning that if a fly walked on it, the fly would die.
There was an episode when someone made some and scattered tiny
flakes of it along the dorm hallway. Any step in that hallway was
punctuated by sharp reports as the flakes detonated, leaving purple-
brown stains on the linoleum.
This was with flakes smaller than a grain of sand. A large amount
would be just as sensitive -- and quite deadly.
