Hello. I have long had a question about pipes - why are they so hard to keep lit? I can keep a cigarette or cigar lit with almost no problem, but with pipes, it's all about constant relighting. I don't mind relighting, it's just that the science-curious part of me is intrigued as to why pipes, specifically, don't want to stay lit. Is it the tobacco itself, or is there something about the physics of pipe-smoking? And no, I don't smoke goopy syrupy aromatics, only English blends. And why can even the gentlest pipe smoking sometimes get hot, whilst I can chug away on a cigarette, and it never gets hot? I'm intrigued by pipes, but frustrated with them at the same time. Taking a gentle puff or two and then putting it down for several minutes keeps the pipe cool, but that's not really my idea of smoking.
