Nov. 22, 2010: Mt Etna smoke ring

A source labels this "A Mount Etna smoke ring", but at first I was totally skeptical; wouldn't the conditions have to be kind of ideal to "blow" a smoke ring? A volcano couldn't do that could it? Doesn't the image look manufactured?

Well, I couldn't find any new information about Mt. Etna's smoke rings... but it turns out Etna has been blowing rings for quite some time.

Who knew?

Don't bogart that lava!

Looks more like The Eye of Sauron blowing a smoke ring while he takes a break.

Totally. Awesome.

Etna's rings, not Laurie Anderson's. WTF was that, anyway?

nonbody mention sheldon.....

If sheldon's ring is smoking, he probably should be using more lube.

whyzit allwayz gotta be about sex withthis chick??

Has it? lol

Sheldon's a stoker, not a furnace...

Does anybody know where to find HD footage of volcano rings (i.e. 720 or 1080 lines)? Some years ago I saw "live" some rings, and it's amazing to see how they're able to "survive" thanks to the rotation of the steam, which is not clearly visibile in low res videos.

note: actually I can't see this video right now from office, but I guess it's one of the low-res ones I already know.

By the way: I have seen some of these rings by myslef: they're real... and amazing! Each one last a couple of minutes.
