Abstract: A modular water pipe system is provided. The system includes a number of geometric members that when combined form a water pipe for use in smoking smokable materials (e.g., tobacco, herbs, cannabis, etc.). The geometric members each include flat surfaces such that a flat surface on one geometric member may mate with a flat surface on another geometric member to form the system. The geometric members are designed to be mated with one another and held in place by gravity and friction. In this way, the geometric members may be combined to form the system for use, and subsequently taken apart for cleaning each member individually and/or for storage. The system also includes a novel tray for holding the smokable material during use.
