When you smoke a pipe, moisture builds up in the bottom of the bowl and in the stem. I'm wondering, is this moisture from the tobacco, or from your breath? I kind of figured its a little bit of both. What I do exhale into the stem, pushing all the excess moisture into the bowl, and then I wave it around a bit and get it all over the wall of the bowl. Seems to dry out better and faster that way,rather than just letting it sit. But is it from the tobacco, your breath, or both?
