One of the coolest things I've ever seen

Dolphins at Sea World playing with self-made bubble rings (think smoke rings minus the smoke)

The next time you are in a pool, try lying on the bottom and blow air rings. It is actually quite easy to do.

I never tried doing it while swimming along the bottom, but I bet you could do vertical rings as well.

(Well, it was summer time and I was bored with just swimming underwater...)
