http://en.wikipedia.org/wiki/Hookah
A hookah (Hindustani: हुक़्क़ा / حقّہ huqqa) is a single or multi-stemmed, often glass-based, water pipe device for smoking; originating in India,[1][2] it gained fame in the Arab World when it traveled from Persia to Arabia. A hookah operates by water-filtration and indirect heat. It can be used for smoking many substances, such as herbal fruits and tobacco. Depending on locality, hookahs are known as other names, such as a shisha/sheesha, water pipe, nargeela/nargile/narghile/nargileh/narguilé, argeela/arghileh/arguilé, okka, kalyan, gewat suckre, or ghelyoon/ghalyan. Many of these names are of Arab, Indian, Turkish, Uzbek, or Persian origin. Narghile (نارگيله) is from the Persian word nārgil (نارگیل) or "coconut", and in Sanskrit nārikela (नारीकेल) and it was made out of coconut shells.[3] Shisha (شيشة) is from the Persian word shishe (شیشه, literally translated as glass and not bottle), and is primarily used for water pipes in Egypt and the Arab countries of the Gulf (such as Kuwait, Bahrain, UAE, and Saudi Arabia). Hashish (حشيش) is an Arabic word for grass(marijuana), which may have been another way of saying cannabis resin. Another source states, "In early Arabic texts, the term hashish referred not only to cannabis resin but also to the dried leaves or flower heads and sweetmeats made with them".[4] Hookah itself may stem from Arabic uqqa, meaning small box, pot, or jar. Both names refer to the original methods of constructing the smoke/water chamber part of the hookah.
