Tony's Smoke Shop

The body of the Tsunami is specifically designed to make the smoke swirl and rise, similar to a tsunami wave swirling at the bottom of the ocean and rising above the surface. Fine punctures are made along its body, creating air-jets which filter out tar particles. Because the smoke rises in cyclone-like fashion, the centrifugal force pushes the tar particles against the inner wall, where they are collected through the air-jets. It is advertised as a double-filtered pipe because of this extra form of tar extraction. Tsunamis vary in size but they all have 6 air jets. This increases the velocity flow of the smoke when inhaling, which results in a quicker, faster "hit".
In addition, the Tsunami uses a special down-stem, which connects to an ash-catcher (a small glass bubble filled with water). A bowl is then connected to the top of the ash-catcher. When smoking, the ash falls into the ash-catcher and is kept there, preventing any solid materials from entering the main chamber of the Tsunami. This feature keeps the main water clean, and many users report a smoother taste because of this. The smoke however, does not filter through the water in the ash-catcher.
