Coke bottle bong

This is a plain design, but the the majority well-organized bong I've establish. Take a 1-litre artificial urn and lay two holes in it, one about middle down the bottle and the other on the conflicting side about an crawl up from the bottom. Take a pipe & bowl (toilet tube is perfect, once again) and insert it in the inferior hole. Hold the pipe up at about a 60 degree angle so that the bottom of the pipe is almost at the bottom of the bottle and the bowl is sticking up as a great deal as possible, and close/paste it in place (I use hot glue for this one and change the bottle about every month, scraping out the old one for resin, keeping the toilet tube). Fill the bottle up with water to about halfway between the two holes. You hold the bottle as the crow flies up so that the bowl is pointing up and absent from you. The hole halfway up on the rear is your carb, and suck from the spokesperson of the bottle. You can also create it out of lesser bottles for more portability, or link two or more bottles jointly, or use bigger bottles for a larger hall... trial.
