I was thinking, everyone and thier cat's lover has propane cannons. I mean, it is burning man afterall. But what about a pnumatic water cannon? Not the fire-fighting kind, but more like the kind that fire a mass of water into the air, and create (more or less) rain shower?
It wouldn't be a steady stream, but more a clap, and then a mommentary downpour. I'm Sure it would annoy the tourists, and thier 4 billion dollar cameras, but spontaneous rain showers aren't out of the question for mother nature either.
What do you guys think about that?
