The things you find on the Internet

I'm no chemist, but when I saw the picture to the left, I thought "this stuff is explosive, isn't it?"  Well, yes.  C₂N₁₄ amino azidotetrazole is so explosive, it emits 357 kcal/mole when you shine a light on it.  This makes its chemical properties very difficult to measure.  Put it in a spectrometer?  Kaboom.  Try to move the stuff across your lab bench?  Kaboom.  "There are no conceivable uses for it."
