Dolphin video that is totally cool!

This video is of dolphins playing with silver colored rings which they have the ability to make under water to play with.

It isn’t known how they learn this, or if it’s an inbred ability.

The ring is a solid, donut shaped bubble about 2-ft across, yet it doesn’t rise to the surface of the water!

It stands upright in the water like a magic doorway to an unseen dimension. The dolphin then pulls a small silver donut from the larger one.

Twisting ring for one last time a bite is taken from it, causing the small ring to collapse into a thousands of tiny bubbles which head upward towards the water’s surface.

After a few moments the dolphin creates another ring to play with.

There also seems to be a separate mechanism for producing small rings, which a dolphin can accomplish by a quick flip of its head. 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.
