This pipe is about 7" inches long. What makes the Absolute Zero unusual is the miniaturized coil condenser. Coil condensers have been a staple of scientific glassblowing for years, but, they are typically very large. The coil provides a pathway for smoke to travel over the super cooled surface of the glass. The smoke is blast chilled and condensed prior to inhalation. Once the smoke passes out of the pipe, it offers a crisp pull that does not burn or irritate the throat and immediately begins to expand. As it expands, the smoke gains pressure and pushes into the deepest reaches of the lungs to provide twice the normal transfer/absorption.
