A very cool video of Dolphins at play. Either that or they are studying us.

Damn it, all those years of believing Echo wasn't real...

Wow. That is the coolest thing I have seen in a long time.

Any idea how they do that? What's the physics behind it?

While SCUBA diving we used to blow air rings all the time, same technique as a smoke ring to do.

*edit* On viewing that video, that is a whole different level of bubble ring. That's blue caterpillar level.

This one does a double ring-merger and seems to soak in the applause it's getting. :)

Swim through five of them to make a star appear...

It's pretty much the same as smoke rings; ring vortices, except with air in the ring, instead of smoke.
