But, all water pipes contain water through which smoke passes prior to reaching the smoker: Water pipes have a head, body, water bowl & hose Holes in the bottom of the head allow smoke to pass into the bodys central conduit This conduit is submerged in the water that half-fills the water bowl.The hose is not submerged, exits from the water bowls top, and ends with a mouthpiece, from which the smoker inhales The tobacco that is placed into the head is very moist (& often sweetened & flavoured) : it does not burn in a self-sustaining manner Thus, charcoal is placed atop the tobaccofilled head (often separated from the tobacco by perforated aluminium foil) When the head is loaded, & the charcoal lit, a smoker inhales through the hose, creating a vacuum above the water, & drawing air through the body & over the tobacco and charcoal Having passed over the charcoal, the heated air, which now also contains charcoal combustion products, passes through the tobacco, and the mainstream smoke aerosol is produced The smoke passes through the water pipe body, bubbles through the water in the bowl, & is carried through the hose to the smoker During a smoking session, smokers typically replenish & adjust the charcoal periodically A pile of lit charcoal may be kept in a firebox for this purpose As an alternative, smokers may opt for commercially available quick lighting charcoal briquettes Q: What is a hubbly bubbly
