I think any kind of smoking/on fire projectile that can be launched, whether with black powder, large sling shot, or smokeless powder, will get you
some attention!
A hollow piece of an old log, "reverse cannon" were you launch the cannon/burning log, would work, there are to many options here to address.
Propellants could be almost anything from deodorant/hairspray, to redneck gunpowder made from coal/fire embers, propane, steam, etc etc.....
Maybe I am not understanding the purpose?
