To make O ring, take a pull on your vape and inhale it into your throat. Keep your tongue at the bottom of your mouth, towards the back of your throat and form a round ‘O’ shape with your lips. Then push a small amount of vapor out using your throat in a short pulsing motion, similar to a subtle cough. The size of the O you make with your lips correlates to the vapor ring you’ll produce.
To make double or triple O ring, simply place a finger over your mouth, pressing and pulling down slightly on the top lip to split the opening of your mouth into two sections. Now you can get two O’s for the price of one! Triple O’s work on the same principle: use two fingers to split your exhale, but open your mouth wider for best results.
