So you're sitting at home, facing a dilemma: You don't have a lot of "stuff" left, so you kinda want the use your one hitter to conserve, but the bong is calling your name too. If you're the proud owner of a 9mm downstem bong, try this next time you fire up:
Put the rubber grommit from your male downstem on a bat from a dugout, and it fits perfectly. Combines the efficiency of a one hitter with the power rips from a water pipe (which is far superior to the super hot smoke from a bat).
Enjoy!
