Sorry to alarm all of you guys with tales of my foolish past. When I was young(er), a friend would do that. I never took part in it. He just pulled all the foolish stuff and I watched.

Yes, a couple times he filled things( bottles and stuff) with blackpowder. He would THROW it in the fire. It never did explode which is why I stated that it's hard to make it explode. It must all be about pressure, which is why a tightly sealed bunch of powder behind a bullet can blow up so fast. That's obvious and is why Frontiers powder didn't explode and just fizzed a little. That's just normal.
