Just an odd little thing I picked up a few years ago and love to do when I smoke a pipe, grapevine says the English used to do this back in the 1800s.
Get a tin of nasal snuff (I recommend the mentholated snuff, or at least English snuff, the German snuff doesn't seem to work.) Drop a pinch into your burning pipe and it opens the whole thing up. Cools the whole smoking experience down. The flavor only lasts a couple of puffs per pinch but it's worth a shot. I don't use the snuff when I smoke a pipe all the time, but once in a while it's a nice change of pace.
