Abstract

A water pipe has an upper tobacco burning bowl. The bowl is sealed into the top of a water chamber partially filled with water. A first narrow tube sealed into the bottom of the bowl extends below the bowl and into the water. A nipple connected to the side of the water chamber receives a conventional pipe stem or mouthpiece. When the user sucks on the mouthpiece, smoke is pulled down the small tube and bubbles through the water to cool and purify the smoke. A second narrow tube sealed into the nipple extends to the center of the chamber. When the partially filled chamber is tilted or inverted, the two tubes always extend above the water level, preventing loss of water. A small hole in the first tube above the water level prevents water being forced up into the bowl.
