[NBC] This Black Smoke Ring Is Amazing, But It's No Mystery

A similar black ring caused a sensation last year when British
schoolgirl Georgina Heap recorded a video of the phenomenon on her
smartphone. The "Black Ring of Leamington Spa" was eventually traced to
a fireworks test at nearby Warwick Castle. Yet another pyrotechnic test
created the same sort of black ring over Florida in 2013. A nearly
identical smoke ring, sighted over Chicago in 2012, was attributed to an
electrical transformer that blew up.
Creating smoke vortices generally requires a blast through a circular
structure — perhaps from a factory smokestack, or a homemade trash-can
smoke ring launcher, or a hippie-dippie apparatus specially designed for
the job. Check out this 2008 video from the Burning Man festival in
Nevada's Black Rock Desert, with "Suite: Judy Blue Eyes" as
accompaniment, and then ask yourself whether the Black Ring of Shortandy
still looks so mysterious.
