Its not the greatest smoking pipe but its always been good for a short smoke on the occasional lunch break and the other day I put a small hole in the bottom. Not a big one but enough that I could still draw some air when I covered the top. Well I set it aside thinking maybe I coule patch it somehow and soon forgot about the hole, only remembering about 10 minutes into a smoke today. It was then that I realized that I was in the middle of the best smoke Ive ever had in that pipe. All I can figure is that the hole rediced the amont of air being drawn in through the tobacco enough that it was able to keep a cool consistent burn. So, pre hole the mini cob tended to smoke hot and fast because even small light puffs in a pipe that small was too much air passing through the baccy. Post hole it would seem that a small hole in the bottom reduced the draw of air through the baccy to make a cool slow smoke. fasinating, I thought I ruined it and somehow I improved it.
