You could make a bong out of a 2 liter bottle.
Melt a hole in the side that's too small for the slide, and while it's still hot, poke it through. This helps keep it sorta water-tight. Tape around it if necessary.
I guess it's not really a slide if it's taped in, but w/e.
Burn another hole for a shotty, fill it with some iced tea, and toke up.
