Tsunami Double Drum Donut Tube (22″) WP-10045 (1 box)

As you pull, the smoke travels through the reinforced fixed downstem, where it first reaches the donut percolator that swirls the smoke around, which cools it off slightly before it gets pushed down into the first drum percolator. The holes in the drum percolator break up the smoke into smaller particles, which increases the surface area, allowing the smoke to cool a lot faster.
