thinking of a homemade pipe. and 1 question

[bashedstoner]

i wanted to make a homemade pipe... that is very unique.
it wll have a glass bowl.
and im not for sure what kind of tube.
i think it will be fine.

i am using one of thoes sample cologne bottles for the bowl. im cutting it where it bends.
so its a ok sized bowl.
i will drill a hole in the top of the lid and might put a screen
i am going to cut a hole in the pipe and seal the cap to the pipe.(so i can unscrew the bowl.
and it should work... hopefully

but one question what can i use for the pipe?
