i made a homemade bong this weekend, my cousin, my friend and i went to walmart and bought a 2L bottle of pop and one of those plastic axe things for halloween, the handle was like 4 feet long, plastic and hollow. we cut a section of the handle about 6" long and burnt a hole in the side of the bottle not to big. while the plastic was still melting a bit we jammed the tube in so it would fit snugg, i went in my garage and found our biggest socket put tinfoil in it for a filter and put the socket into the plastic tube. it fits perfectly. i was amazed and the socket held alot of bud and the bong worked awesome. give it a try.
