This is accomplished by holding the stir tool on the bottom end of the mouthpiece, and then rotating the mouthpiece tip counterclockwise with the other hand. Then, replace the mouthpiece tip with one of the two included adapters. Refer to the picture below to see how the adapter looks when properly installed. Finally, insert a glass mouthpiece by sliding the round end of the glass mouthpiece over the two o-rings until reaching the stopping point.
