Smoking is injurious to health, we all know this fact, but sometimes its fun to know what kind of tricks you can actually pull off while smoking. By opening your mouth to form an oval shaped aperture and blowing the smoke out by raising and lowering the lower jaw (the presenter prefers this way) you can easily create ring shaped smoke puffs. The other way to achieve the same result is to simply blow carefully without raising or lowering your jaw. As is the case with almost every skill in life, only constant practice can ensure that you will be able to do this trick easily.
