Falcon Pipe Bowl - Chimney Short Stack LinedAmerican engineer Mr Kenly Bugg, of Fort Wayne, Indiana invents the Falcon Pipe, with its aluminum stem and interchangeable briar bowls. He bases the system on the principle that causes rain to drop from a cloud when it is met by cool air. To achieve this result, Mr Bugg uses aluminum for its lightness and, more importantly, for its quick dispersal of heat. In this manner coolness is obtained. The briar bowl, designed with a four-start thread connected to the aluminum stem, forms a trap in which the 'Humidome' acts as a condenser. This ensures that all the moisture is trapped, thereby leaving the tobacco free from saturation and preventing 'goo' from reaching the mouth of the smoker.About this bowl...Bowl Material: Briar Shape: Short Stack ChimneyFinish: SmoothMeerschaum Lining: NoBowl height 45mmBowl width: 33mmSmoking chamber diameter 21mmBowl Weight: 18grams
