Thats kinda reminds me how I disposed of some old gunpowder. Dumped it

the pile of powder. Very impressive, but too expensive to repeat!

That's smokeless powder, try it with black powder Here's an
experiment: put a tablespoonful of black powder in an ash tray. Touch it
off with a blowtorch held at arm's length. The powder will burn fast
enough to extinguish the blowtorch.
