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. 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!
