Poke a "drain hole" somewhere in the circumscribed gutter. That's
where you can shove spilled powder rather than suck it into old
sparky the vacuum. Spilled powder can be spread on the lawn or
garden, it's good nitrate fertilizer.

Ooh, ooh! I wanna come to your house and throw a lit sparkler on your
lawn to watch it _explode_! g

If you ignite unconfined modern smokeless gunpowder, it just burns. If
you confine it, it burns faster, but it still doesn't explode, even
inside a cartridge fired in a firearm.
