GRAV Mini Hammer Bubbler
This hammer style bubbler stands at 4" tall and is made from 25mm tubing. The fixed downstem has 3.5mm diagonal cut slits at the bottom to provide enough percolation to avoid splash back and cool the smoke before it hits your mouth.
This is a simple bubbler from GRAV Labs with the mouthpiece, downstem , and feet all being colored and the body being clear.
You may want to watch where you put it down, although it does have nice sturdy feet the mouthpiece also hits the tabletop. So in order to keep it clean make sure you are wiping down an area before standing up your bubbler.
