So i was sitting around today hating dry vapor when i had an idea, build a bubbler! so two hours later here is my results, That is a beer bottle with a nice diffused downstem inside. I hand cut the hole with my Dremal tool and a round diamond tip bit. The downstem fits snuggly and i used a thin bead of hot glue to make it air tight. (the solo stems for demo purposes only) I wanna see what other FC'rs have created, post your creations below(: have a good day.
