The Hammer Bubbler made by GRAV is an essential part of every smoker's collection! It is 4" tall, 7" long, and made on 32mm tubing with an etch label. The body of the bubbler is clear while the mouthpiece, down stem, and feet are coloured glass. Its fission down stem diffuses smoke through water, and its feet stabilize the bubbler between uses. No accessories are necessary for using this bubbler, and it functions best with about half an inch of water.
Bubblers offer water pipe function and filtration in the convenience and portability of a standard hand pipe. Plus, a bubbler is versatile and can just as easily function as a dry pipe by not adding water!
But if you are going to add water, having just the right amount of water is essential to your smoking experience. Having too much water can create backsplash or give you stale hits. Not having enough water doesn't filter the smoke and it can be pretty harsh on your lungs.
