dolphin, rings, ravel

"An explanation of how dolphins make these silver rings is that they are
'air-core vortex rings'. Invisible, spinning vortices in the water are
generated from the tip of a dolphin's dorsal fin when it is moving
rapidly and turning. When dolphins break the line, the ends are drawn
together into a closed ring. The higher velocity fluid around the core
of the vortex is at a lower pressure than the fluid circulating farther
away. Air is injected into the rings via bubbles released from the
dolphin's blowhole. The energy of the water vortex is enough to keep the
bubbles from rising for a reasonably few seconds of play time."
