Cheap and customizable home made water bong

You might think this is wasting of time since most of you already have a water bong or you prefer other ways to smoke, but hey, this is fun and cheap, you can get all the lab supplies on ebay, my design is just an idea, through it you can pimp your bong whatever the shape and size you like, you can even add a Y shape connector on to get 2 people high at one hit.
