ABSTRACT:
A smoking apparatus which efficiently removes harmful impurities from the smoke does so by improving contact between the smoke and a washing liquid. This is accomplished by placing small stones and small floating pieces in a water pipe to increase the distance of the flow path of the smoke through the water, and to decrease the size of the smoke bubbles passing through the water.
