Along these lines, Hows about this idea? Take a tank of Propane up on the roof, let it freeflow a good amount down inside your chimney, then, go inside and strike a match in your fireplace?
It will be like a potato gun! Holler out, "To The Moon Alice!" and strike that match! Boom! Quickly run outside and start singing..."Its raining coons Hallelujia!"
Lets have some fun here for once!
