Looking for Double the Bubbles?

A diffused downstem is a simple glass tube that pushes the smoke down through the water. Smoke diffuses into the water through the downstems holes or slits, spreading it throughout the liquid and cooling it down.

No more harsh inhales with a diffused downstem on your favorite bong or water pipe! 

The more diffusion, the smoother the hit!
