The UPC 8" Straight Water Pipe is great example of a simple, affordable, and most of all high quality glass bong. This water pipe stands 8â€ tall and features a removable diffused downstem at a 45 degree angle to the main straight tube. Diffused downstems are one of the most simple percolator designs, yet extremely effective in diffusing and cooling the smoke for a less harsher hit. The downstem has slits or holes at the the base of the glass tube where it meets the water which allows for the smoke to diffuse and be cooled before traveling upwards. Sitting on top of the downstem area is an ice pinch. This allows the user if need be to put some ice there for further cooling of the smoke before inhaling. With the removable 18mm to 14mm downstem and heavy bowl, this simple bong can be slightly modified with new downstems and bowls as well as easy to clean. Get yours today for a great low price!
