i recently made a cumbersome yet enjoyable waterfall bong, just pretty much got a big old fruit punch container, put a bowl in the lid, and a finger sized hole in the bottom. Then you fill a mop bucket with water, or whatever liquid you like, and submerge the bottle in the water until it fills up through the hole in the bottom, hold it there, fill the bowl, (this is a two person procedure btw) one person holds the bottle above the water with a finger in the hole, keeping the water inside the bottle, one lights the bowl as the other lets the water pour out of the hole, the smoke will be sucked into the bottle and you can do an entire bowl in one bottle full, then you just pass it around and **** out of it. I know its not practical, its not a real bong, and a big waste of time, but if your like me and get pleasure from the little things like how cool smoke looks when it's pulled really fast and forms funnels and the like, then you'll enjoy this. Sorry for the rant but thats just a fun little thing i made
