the bowl itself unscrews from the metal piping that u put into the rubber grommit near the bottom to get it submersed in the liquid u put in there. both are a silverish metal, its not aluminum, i think its steel or S.S. the upper chamber where u put your mouth is seperate, or comes off rather because u can either put the "ice twist" on or the plain cylinder shaped one. and the only other piece is the rubber ring or w/e that goes on the end of the pipe that u put ur mouth on
