AA (azidoazide azide) is a hyper-explosive 14 nitrogen molecule. My questions are: what are some theoretical ways to store it so it doesn't explode on you but on the enemy you throw it at, and what would be the feasibility and practicability of this as a weapon?
From the Things I Won't Work With blog:
The compound exploded in solution, it exploded on any attempts to touch or move the solid, and (most interestingly) it exploded when they were trying to get an infrared spectrum of it.
In other words, there is no practical use for it - it is far too unstable to even get it out of the lab that produced it, much less into any sort of weapon.
