For all bubble friends. Here it is important that the bowl is upright and parallel to the pipe. In order to secure the gauze as high as possible in the bowl, the 3 gauze fixing dots have been invented. Like this, the gauze is really lying on top of the bowl instead of being down in the bowl. Nothing vanishes into the depths of the bowl; you have always clear view and are hence in full control of a perfect combustion process.
