The Incredibowl's nozzle works as a heat sink. The hot smoke pools inside the nozzle and then the cooled smoke passes across the even cooler fine-mesh stainless-steel screen. The tars in the smoke are cooled and condensed by the time they pass through the screen, making them thicker, stickier and easier for the screen to catch. When gasses expand, they increase in volume, decrease in density and lose energy in the form of heat in the process. Other pieces leave much of this cooling, filtering and expansion to occur in your throat and lungs, resulting in harshness and lost flavour but this doesn't happen with the Incredibowl.

When you create suction, you're creating a difference in pressure between the Expansion Chamber and the atmosphere outside the chamber (which your suction doesn't affect). When you pull the carb, the pressure inside the chamber has to become equal to the pressure outside, which forces air through the carb holes. The geometric arrangement of the holes causes the air to rush into the chamber as a symmetrical system of air jets that displaces the smoke quickly and smoothly into your lungs and demonstrates the Incredibowl's ergonomic design.
