I dont think it will work. At least until the water reaches below the stem, but then only a tiny bit of smoke would fill up. I dont know

Question about waterfall bong Ok, so I'm making one now and I've got this idea to put a long stem into the bottle so some of the smoke will be filtered through the water as it feels up. My question is... will it work? I've never actually used a waterfall so I'm not sure. I know it has to be airtight. I have a pic of what my plan is. I just need to drill a hole in the bottom and make it airtight and it will be finished. Rating: 5
