Its fission downstem diffuses smoke through water and is fixed inside the bubbler to prevent damage. The lip of its mouthpiece is ergonomically designed for comfort, and its mouthpiece restrictions capture and ripple light. The Upline? Upright Bubbler comes ready to use with a 14mm Octobowl and works best with approximately 2" of water.
