A bubbler is a handheld water pipe that shares similarities with a typical pipe, featuring a mouthpiece connected to a stem and a fixed bowl with a carb. However, what sets the bubbler apart is the water chamber located beneath the bowl, which filters the smoke, resulting in a cooler and smoother throat hit. When the bubbler contains just the right amount of water, it produces satisfying bubbles without splashing into the mouthpiece or flooding the bowl.
Various designs of bubblers exist, including the Hammer, the Sherlock, the sidecar, double bubblers with dual filtration action, and bubblers designed solely for concentrates. In comparison to a bong, a bubbler is more portable, while still delivering smoother hits than a dry pipe. Therefore, it earns its place as a must-have smoke delivery system in the collection of every cannabis connoisseur.
