Introducing the Avant Dewar Sherlock Bubbler Prototype #1. This new school meets old school Sherlock features Avant-Tech function through fumed inside out rod sections. It has a low profile Dewar like 14mm joint set into the carved iridescent Sherlock head. We used some Greasy Glass Purple Satin and a layered shifty NorthStar color mix in this unique prototype. We wanted to make this piece hard to spill, so we added some membranes with slight depressions to help prevent spillage. The Avant-Tech section has a vey airy hit with minimal water needed to produce smooth percolation through four holes. Starting from the joint: smoke travels down to the bottom of an inside out sections where it's drawn into the walls back up to the top of the inside-out section, before traveling back down to the bottom of the section where it is introduced into the water in the lower water chamber. It is then drawn up the walls of the second inside-out sections where it lightly percolates throughout the walls. When the hit is complete, the water travels back down to the storage chamber.
