This Icebong has a completely new way to energise and diffuse the smoke. Not only, is the down-pipe redundant, because the large Roll-Stop bong bowl inserts directly into the flue, but the Smoke Generator acts like a water-wheel and is spun by the smoke flowing up from the water-chamber, via a small hole in the glass disk, which separates the upper and lower chambers. The flue has a reinforced angled inlet with a Sure Ground (SG 19) fitting and two inlet pipes. A large at the bottom, for the bulk of the smoke and a smaller stabilising tube that feeds into the upper chamber further spinning the smoke-wheel. The upper section of the main tube comes with 3 Ice-Notches. The swirling and cooling make the smoke very smooth and pleasant. Impurities are filtered and left in the bong. Thus, smoking makes for so much fun!
