st started smoking again after a break, starting from the bottom but it works. I've made tons of homemade bongs before (like literally 80+) it only looks really shitty cuz i'm using duct tape instead of super glue/a glue gun to seal the gaps. it's 100% air tight and functional i made the "precision" hole cuts with a combination of a box cutter and lighter to soften the plastic to mold it more easily. 2 pills bottles + cut up pieces of straws taped together + 2 pen casings + tin foil bowl (i don't care about your "oh no its toxic" arguments btw so spare yourself typing up a speech) total cost: $0.00 2 chamber mini bubbler with carb hole my visiual blueprint of how it works/the concept.
i wish we had a toxicologist around obvi its a temporary thing, and i'll worry more about my cig habit before i feel like i'm "killing myself" from the faint wisps of plastic "fumes" lol. glad you can appreciate the craftsmanship though!
