Madness string 21692

Random mermaid
I've done far stranger, for far more questionable of reasons. Like the time I robbed a 7-11 at gunpoint for a pack of gum because a drunk told me he'd tell the world who I was if I didn't, and when I seemed interested in who he thought he was, he said he'd tell me if I did it. Except then he was gone when I got back, so I just returned the gum and fenced the gun and made a tidy 200 dollars.

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.
