so me and my friend were in chem and were using 500 ml cylinders, and we decided to jack it to make a homemade bong. it was pretty sweet, and then i thought of the best idea for a makeshift slider. a trumpet mouthpiece. it looks just like a slider, is metal, and better than fucking sockets for other homemade bongs.
just thought id let my fellow stoners know, and if you know someone with a trumpet, i suggest stealing their mouthpiece next time you make one
