At CATO on saturday, someonw had an F25W single-use motor that CATOed (i.e, exploded). It wasn't terribly violent - it just lifted off the pad, spit out the nozzle, and then the rocket fell back to the ground. I found the propellant grain on the ground; it's mostly unburned. I'm going to keep it.
I'll mainly use it as an ignition helper; I can cut off little slivers and stick them in hard-to-ignite motors along with the igniter. This'll be especially helpful for Blackjack motors which are very hard to ignite.
Of course, I can also just burn some of it for fun, or to start a campfire or whatever. A match can light it, and even a little bit burns with an impressive white flame. Ammonium Perchlorate Composite Propellant (APCP) is cool.
