Bubblers are a form of water pipe. They get their name from the bubbling action created as the smoke is drawn through a chamber filled with water.
Bubblers have three essential parts: a bowl, a chamber, and a mouthpiece.
You load your herb into the bowl, light it up, and draw through the mouthpiece. As the herb burns, smoke is drawn down into the chamber where a small amount of water provides filtration.
After leaving the water, the smoke makes its way through the remainder of the chamber and is inhaled through the mouthpiece.
