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.

A device to be placed in the bowl of a pipe that permits smoke to pass while blocking the material of a burning charge is described. The device includes a screen with a U-shaped staple passing through two holes in the center of the screen. The two points of the staple may be temporarily compressed to pass through the screen, then the points spread so as to make a friction connection with the insides of the bowl, which removably secures the screen in place. The device is free of other holding structures, such as straps. The device is adapted so that a thumb and forefinger may easily grasp the top of the staple for insertion and removal in a bowl. In an embodiment the points of the staple are adapted to push through the screen, creating the holes. An embodiment is adapted to be used in a drainpipe.

The present invention relates to a smoking device, which comprises a combustion section and an exhaust line. The combustion section includes a combustion chamber for housing tobacco and the exhaust line has an inlet portion and an outlet portion comprising an inhalation opening. The exhaust line is forming a canal surrounded by a tube wall. The intake, the combustion chamber, the exhaust opening, the canal and the inhalation opening are aligned with the longitudinal axis. Optionally, the combustion wall and the tube wall are also aligned with the longitudinal axis. The combustion section or the combustion section and the exhaust line is/are substantially made from a ceramic material. Such ceramic material could be for example, but not limited to, earthenware, stoneware or porcelain or porcelain containing kaolin. Furthermore, the entire smoking device can have conical outer shape with a substantially continuous outer surface, in particular, the entire smoking device has a truncated conical shape.
