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

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.

I sure hope that you meant demonstration rather than experiment; because I'd
be way too scared to try anything like that on an experimental basis.

BTW, the USAF must have been an entertaining place. :-)
