What is Smoke Ring?
1.
A smoking trick where a person expels an "O-shaped" ring of smoke from the mouth. Smoke rings can be formed using a variety of techniques involving controlled muscle movements in the air passages to produce the effect. Typically, a circular opening of the mouth is made and the smoke is pushed through the opening with a gentle exhaling puff made by quick movements of the toungue and throat. Rings can also be made by taking smoke into the mouth, forming a small "O" with the lips and then gently tapping on one's cheek. Blowing smoke rings usually takes practice and the best technique varies from person to person.
I always thought smoking looked cool, remembering when I watched old cartoons when I was a kid and some cigar smoking character dipped his smoke ring into his coffee like a doughnut!
