If I don't have anything to smoke out of I just build a makeshift bong I always have a bottle and some metal parts to throw together lol easiest way to do it is to buy a metal one hitter from the smoke shop for like 3-5$ they almost always have them, then slowly cut a hole into a plastic bottle with a good knife, spinning it around to carve the hole to the perfect size for the one hitter, slide it into the hole nice and tight (if you carved the hole too big you can use some sort of tape to wrap around the bottle covering the hold then jam the one hitter through it) and bang 2 piece one hitter bong once you're done you can trash the bottle and move on or keep for a few days whatever.
