A water pipe, hookah or bong is a device used commonly for smoking, usually tobacco (and less frequently Cannabis or other substances), in which smoke is bubbled through a chamber containing water. The bong enables the operator to smoke in a manner very different to what is possible with a simple smoking pipe or joint (spliff). Most bongs are designed to either cool the smoke before it enters the operators lungs, build up a large buffer of smoke which the user inhales quickly, or both. The word bong derives from the Thai word baung (ºéÍ§) which refers to a cut off section of bamboo.
Bongs also vary greatly in their shape, materials, colors, and sizes. Commonly constructed from acrylic, ceramic, or glass, bongs can also be fabricated from materials as diverse as pykrete or even from household objects. Some people make bongs out of fruits and vegetables, discarding them when they start to decompose. Many bongs are regarded for their style, distinct vivid colors, or customizations such as stickers, and become a personalized signature of that particular bong owner.
