You may or may not have seen this before, but it is pretty neat. The video is on site.
Dolphins create bubble rings by blowing air in a water vortex ring: by flipping a fin they create a vortex ring of water. The then blow air in the ring, which goes to the center of the vortex ring. In the water vortex ring the natural location of the air is in the center of the vortex. When air and water move in a circular path like they do in the vortex ring, air and water are separated due to the centripetal force. Since density of water is larger than air, water moves at the outside, while the air ends up in the middle. -Deep Ocean

Thanks for the smile and the mental vacation......
“So long, and thanks for all the fish.”
That’s really cool! :-)
They are smarter than Obama.
Gross!
I think it’s only the Japanese who eat the mammal called dolphin. Shame on the Japanese. The other dolphin is a fish otherwise known as mahi mahi. The mistake is a common one.
They are super cool critters.
Amazing! Thanks for posting.
Well, at least it’s cutting down on their smoking.
Whats cute is how often you jump on the first post of a thread with the intention of derailing it by posting a contentious picture/message. Even non-political ones...you must like to keep in practice.
I bet you think no one notices, don’t you? Yeah, blah blah, Obama moral equivocation, appeal to authority, blah blah blah here comes the anecdote your cousin did that one time blah blah. I know all your responses.
Whatever dude, you need to get a life if you are that obsessed about reading into things that you keep track of what folks post to try to make a psychological determination of their intentions.
By the way, welcome to FR newbie. You really are starting out well aren’t you?
Very creepy.
