This diffuser water bong has 8 arms and it uses all 8 of them to deliver a perfect smoking experience for you. The diffuser breaks apart the smoke into miniscule bubbles which then go through the 8 arms. This removes all the heat from them which results in a smoking experience that is chill in every sense of the word. It also has a great design and is made of high quality borosilicate glass. One bong rip from this will make you and your friends a convert ‘ you won’t be able to go back to the normal bongs that send you into a coughing fit.
