Good idea. But, the other day I was wondering... I have actually tried to use the stingers and little tube-like stingers in my pipes. I figured, if they come with the pipe, they must work. I've tried smoking even slower than normal. I've tried smoking harder, faster, sipping, holding the pipe in my hand, upside down, turning the stinger different ways, I even smoked one till it was completely broken in, and every pipe with a stinger gurgled, no matter what I did. And, pulling the stinger out... the pipe smoked fine.
Is there anyone in the known universe that has mastered the stinger? And, if so, please give me the secret. Pipe makers keep putting them in pipes, even new ones will still have them. So, someone out there must know something that I don't. Or, are they required by law in some countries top discourage smoking? Why do they put them in pipes?
