ideas for makeshif pipes and/or bongs?

i hate using foil... i think it makes the taste worse... plus foil is horrible for u and the foil can get hot as hell

 

although i will never be desperate anymore thanks to my extensive collection of smoking utensils, lol

but i used to just break out the old soda can, or just find a piece of paper and roll one up, but i used the good old soda can the most.. but that was when i first started smokin, now im spoiled i got:

a bong
glass bowl
regular old bowl
plenty of rolling papers
5 xtra screens
4 lighters
and a grinder

what else would ya need?
