I DO NOT WANT TO USE ANY KIND OF FOIL. ive heard of trumpet mouth piece and wrench socket any other ideas?
Thimble, door stopper in a sharpie highlighter tube makes a real nice slide, get some screens and almost anything metal should work.
Check out the plumbing section of your Hdwe., Home depot, or Lowes. Brass fittings, copper tubing etc. bamboo makes a good stem. work your imagination on it. peace
if you're familiar with woodworking i made a beautiful one hitter on a lathe. actually more than a one hitter...but not quite big enough to consider it an actual bowl.
