Attention Bill, I figured you'd find this interesting.

Its two vortex rings of different colored smoke hitting each other
head on. Very cool.
That's astounding! Who would have though it would be so symmetrical.
It must be perfectly still air inside the test box.

That's a splendid little video, and an elegant demonstration of spin
conservation. I urge people to see it.
The air particles and spin both rotate 90 degrees as a result of the
collision. Fascinating!
It would be interesting to see how this works in a low pressure cell, close
to vacuum. I wonder

It looks authentic enough -- but it's *NOT* smoke rings.
It's dye

water.
That is more likely, but unless the speed has been altered, water viscosity
would likely not permit that kind of apparent speed.
I suspect that if it is not
Those kinds of smoke rings are fairly common. The smoke is trapped in
the narrow core of a much larger ring-vortex. It's laminar, otherwise
the smoke would appear as a whirling cloudy structure.
I heard that some local guys ten years ago set off a homemade gasoline
bomb in a parking lot.
