I'm brain storming for next year to figure out how to make the stream that runs next to the sidewalk to the front of our house smoke or fog. I was thinking of either a fog machine, but would need to run it over dry ice to get it to sink. I also thought about just throwing some big chunks of dry ice in the creek and letting it fog and bubble.
Any other ideas? The stream is fed from a covered resivoir at the bottom and pumped to the top and recirculates.
