Simple and dependable, this 12 inch single chamber glass water pipe does one job well: cooling smoke through water. With a single chamber, there are fewer nooks for residue to hide in, so it's quick to rinse and easy to keep clear. The 12 inch height sits in a comfortable middle ground. Fill it until the downstem sits just below the water line. Clean it weekly with a glass cleaner and a warm-water rinse to keep the glass bright.
