This clear glass beaker bong from Nucleus displays a buoy shaped chamber that has the dual use of providing a sturdy base as well as giving it appealing visuals. The water pipe combines percolation technology with an ice catcher to ensure you get the smoothest hits possible. The 6" 18mm male to 14mm female diffused downstem contains 6 slits for diffusion and distillation of your smoke. The donut ice catcher cools the already filtered smoke. These two features work in harmony to provide optimal rips with every use. Included with this scientific glass beaker bong is a deep 14mm male bowl with three raised glass bubbles. The mouthpiece has a flared construction to fit comfortably to your lips while also providing an air-tight seal.
