Re: Project: Cold Smoke
I think esg's comment would be worth a shot. Use a small gauge hose and put it in a larger one. Seal one end, then fill it about 1/2 to 2/3 with salt water, then plug the other end. I don't think that the water would stay in the hose though, which would be a major problem.
As for the chamber, that's awesome! Might I suggest getting some copper tubing to run from the input hose to the output? Coil it around a few times, and you should be good there. You wouldn't have to worry about the holes getting covered or pulling water into the hose either.
Keep us posted on how it's coming?
