The Structural Science of Vortex Rings


A vortex ring forms when a very quick burst of fluid shoots out of an opening. As the fluid moves forwards, it spreads out and its front edges curl back. If the speed of the burst is fast enough, the curling fluid eventually curls all the way round, until it is travelling forwards again in the direction of the original burst.
