The Hot Box Spinning Bubble Carb Cap
Carb caps are getting more varied and complex as people's knowledge of dabbing and concentrates becomes more developed and these spinning bubble caps are another great little innovation which we knew needed to be added to The Hot Box range.
They can either be used as a straight carb by covering the side hole, making the air flow straight down the central shaft, or if you instead cover that straight tube, the air will rush in the side hole and must then travel through the spiral tubes which makes the air inside the banger spin, creating vortices which help the vaporization process. Not only that, but the spinning effect is great for if you use terp pearls as the vortex makes the terp pearls spin inside the banger.
These carb caps have an outer bubble diameter of 30mm, which makes them perfect for bangers with an inside diameter from 18mm up to 29mm.
