Bubbler is the hybrid version of the pipe and a bong. If you'd say chillum is the small version of the regular hand pipes, the bubblers could be the mini version for the water bong with carburetors on the side with no rig. Bubblers come in a variety of sizes and shapes, especially our Honey Bong ones. They also require water for filtration use. We recommend bubblers to anyone who likes to experience filtration and smoothes inhale of cool smoke of the bong at a smaller version.
