Um, 1) How did no one notice a drug we've been using since the 1970s is very explosive
2) How did anyone NOT think THAT drug was explosive? LOOK AT IT. LOOK AT ALL THAT NITROGEN.
@Canageek Yeah, I'm on team “What percentage of compounds with 3 N’s in a row are stable?” 
@Canageek I'm a little concerned that "weighable" is a notable characteristic of this compound
I don't like being reminded how many chemicals there are that are too volatile for us to actually measure how much we have
@WizardOfDocs Weighable means can exist as a pure solid: Lots of compounds like this would need to stay in solution, which makes measuring them annoying, or are gases, etc etc. You want pure liquids or solids to make working with it easy.
@Canageek Uh. Goodness!
