So I was at a bar I frequent here in Japan and pulled out my pipe and lit her up when much to my surprise the owner said he used to smoke a pipe years ago. I handed it to him so he could take a couple of puffs. He used a strange technique that I have not seen or heard of. He put his thumb over the bowl and would take a few puffs while raising his thumb just off the bowl. It's hard to explain and I am sorry if this doesn't make any sense. Does anyone know what he was doing and why?
