Extraordinary and beautiful examples of toroidal vortices produced by dolphins, beluga whales, humpback whales, volcanoes, hydrogen bombs, and man.
A toroidal vortex, also called a vortex ring, is a region of rotating fluid moving through the same or different fluid where the flow pattern takes on a toroidal (doughnut) shape. The movement of the fluid is about the poloidal or circular axis of the doughnut, in a twisting vortex motion. Examples of this phenomenon are a smoke ring or a microburst. Vortex rings were first mathematically analysed by the German physicist Hermann von Helmholtz, in his paper of 1867 On Integrals of the Hydrodynamical Equations which Express Vortex-motion Smoke rings have probably been observed since antiquity since they can easily be blown from the mouth.

“Too cool” is, of course, what I meant to spell...
...and women...
Here is a pic of my wife when I asked her if now was a "Cialis" moment.
All this crap of aspirin and abstinence.
Yeah, right.
We practice absentance...
Ultra cool. Thank you.
Ain't it though? and you're welcome.
Back in the day it was cool to get out and see the spray plane levying death , in the predawn hours, with that nerve agent redesigned to kill bugs (and pregnant women). Double vortice.
Fortunately now that pesticide is banned and you get your veggies for free from Mexico-co,/.inc.
I feel your pain...toroidal vortices are a lot harder to come by these days.

I am checking into laser surgery for mine. They say it can be handled on an outpatient basis.
There was also a day in my childhood when I got to see a very black "jet" fly over our town and then go ALOFT very fast. Boom,boom, boom. Ringy, too. From a location I can see from my backdoor. They called it "the base" then. Now it is the INL.
What happens in Vegas, stays in Vegas. But in these days it may be a case of Herpenstance and then it is MRSA me....
“We practice absentance..”
Is that the Royal “We” or the Editorial “We”?
;-)
All ya gotta do is ask and she responds with the big smokin’ O???
No wonder you have a big head old pal....
Oh, yah. Either way, it is a big smokin’ O. bigheadfred is just a simple locker room nickname...
And you get tons of e-coli bacteria for free! Hey, field workers gotta go somewhere......
Kinda like “in your face, MF...???”
We’re practicing absence...Mrs. BN is out of town helping a friend after surgery.
Mrs. bhf is out of tune too. But I just paid $5000 to have her tuned up. Which brings up a really interesting philosophical debate. Who ends up who bleeding who to death????
