I just made this bong. Practically took like 2 minutes. Hits better than any other homemade bong I've ever used. Thing is I'm not a huge fan of paper towel rolls as theyre made of paper and look horrible. Any common items that are glass or plastic that I could use would be cool.
Have you thought of buying a non-homemade piece? I just dont see the point of it unless you hate joints/blunts and really can't afford a glass piece
