Percolator Bongs - The Best Of All Types | EveryoneDoesIT US
Percolators are additional filtration chambers located inside a bong or water pipe, usually inside the main chamber or within the tube on the way to the mouthpiece.
Working Principle of Percolator Bongs
Although there are many different styles of percolator that appear very different, the basic principle is the same with each: smoke and water are forced through the percolator by the negative pressure from the user inhaling on the bong. Firstly, this accelerates heat transfer – that is, the hot smoke is rapidly cooled by the bubbling, aerated water. Secondly, this action breaks up the smoke into finer particles, increasing the surface area. Again, this cools the smoke as well as filtering out some of the harmful carcinogens and particulates from the hit. The result is a spectacular bubbling action and a smooth, cool hit every time.
