Abstract
Abstract A smoking pipe having a means for removing tars, and other particles from the smoke by the principle of occlusion by water vapor. The water vapor is produced by heat released from burning tobacco. The pipe also has a transparent bypass located on the stem to encase a filter for tars and other particles. The transparent character will allow observers to view the filtration process.
