Also, I just wanted to show that I cut down one of my stems to better fit my needs. I also am using a 18mm water pipe adapter I had for the Eclipse vape. The tubing fits perfectly in to it. I know have the idea to make a bunch of roughly .75inch bowls and just save up a bunch and do a wash of them all, or just toss them. Either way, I like having a clean flavor and this is a great way for me to do so. in addition, its nice to have the GONG attachment.
In the picture you can see I used a razor blade to cut the tube, worked perfectly. Also have my screen really high up there. I still have yellow abv, and not brown, but Im getting good hits. Kinda confuses me. I do get more out of the toasty top afterwards, but it is quite flavorful.
