This could very well be the most beautiful bubble ring (also known as a toroidal vortex) ever recorded on film. This clip is from the award-winning IMAX classic, DOLPHINS by MacGillivray Freeman Films, founders of the One World One Ocean Campaign.

A toroidal vortex, also called a vortex ring, is a region of rotating fluid moving through the same or different fluid where the flow pattern takes on a toroidal (doughnut) shape. The movement of the fluid is about the poloidal or circular axis of the doughnut, in a twisting vortex motion. Examples of this phenomenon are a smoke ring or a microburst. Vortex rings were first mathematically analysed by the German physicist Hermann von Helmholtz, in his paper of 1867 On Integrals of the Hydrodynamical Equations which Express Vortex-motion Smoke rings have probably been observed since antiquity since they can easily be blown from the mouth.
