Bubbler

ˈbə-b(ə-)lər | Noun

A hand-held water pipe. Similar to bongs, bubblers have a mouthpiece, bowl, stem, and water chamber. Most bubblers have fixed bowls that can not be removed. As the name implies, the bubbler may also contain a percolator that aerates your smoke. Bubblers with fixed bowls feature a carb, or hole, that is used to clear out the smoke.

 

That bubbler gave me the smoothest hit ever.

 

The percolator on the bubbler changed the air flow and provided a smoother hit than the dry pipe.
