A straight base is a classic water pipe silhouette composed of a glass tube fixed to a broad glass foot. A smaller, L-shaped piece of tubing is welded to the main tube just above the foot, and bends upward at a right angle. The smaller tube is capped with a ground joint, and usually features a glass bridge connecting the joint to the main tube. The main tube extends all the way to the mouthpiece, usually with some kind of restriction, perc, or ice catcher halfway up the pipe. Straight based water pipes hold less water than beakers or round bases, but they don't require a downstem, making them easier to clean and use and simpler to pair with accessories.
