Ok so tonight i'm making my first homemade bong out of a plastic bottle.
First of all, is a carb necessary, and if so, what is it used for?

Also, any good ideas as to what i can make my cone peice out of (from household objects)? At this point all i got is an Al. can, which i'd rather not use due to paint/toxic fumes.
