You may have noticed smokers trying to grab your attention by their potential of puffing smoke rings and making smoke clouds in air. So, if you thought this skill is pretty cool stuff, then you shouldn’t miss out on our own natural surroundings, which have certainly mastered this time-honored smoking skill.
One such example is a recent happening that took place on 11th April 2013, in Mt Etna, Italy. It’s known for its fiery volcanic eruptions and is continuously been surprising us by its startling smoking knacks. This mountain blows the best smoking rings in nature. They are usually 100-200m across.
Each astounding spectacle of these sizzling peaks will make you think that it all happens by a mere chance; however, every smoke that this mountain emits holds an explanation and has a scientific reasoning which you may not be really aware of. These volcano smoke rings are usually meter-wide rings made up of smoke or vapor. No there isn’t any giant sitting inside struggling and blowing smoke rings of neat shapes, but it’s all because of a scientific exertion that makes things go in its favor. Yes, there is a little bit of “science” everywhere around you!

The scientific term for these rings is “Vortex Rings.” They are formed when the air is mixed with steam or smoke and is forced out of a small circular or cylindrical opening. Because, there is a narrow drag at the surface of the opening, the air in the center is forced to move faster than the air near the opening, ultimately creating a circular motion. In this way, a doughnut like vortex is formed. The shape of the ring is maintained due to the rotational motion of the air that constantly keeps flowing in the vortex ring. In short, a brief explosion in a confined outlet with just the right velocity allows for that impressive “puffs” eventually expanding into an unbelievable ring. It so reveals how nature’s geometric configuration can actually become so sensible and artistic.
