Thats... So many really good questions. The only one I can answer is that rain definitely reduced the pm2.5 levels at our house. Before it rained, the smoke was below the tops of the trees and according to my phone, we were in the 150+ range. After the rain, it was easier to breathe and no warning on the phone. So mist will likely help better than a stream. I imagine (but lack evidence for) wet leaves remove more particles from the air if there is a breeze. Im not sure how you would go about devising an experiment to test for that though. I think your bong would have to be very big to have an appreciable effect, but you might have a better time of it if you can make it like a wall you put on the upwind side of your property so it filters air coming in.
