Fluid Dynamics: What Happens When Two Identical Vortex Rings Collide

November 28, 2016


This is an older scientific video of some crazy fluid dynamics in action. Or, in more scientific terms, "a head-on collision of colored vortex rings. Note the formation of small rings from the cross-linking of the wavy vortex filaments of the larger rings." So basically this steamy video has it all: colored vortex rings, cross-linking, wavy vortex filaments -- you name it. I swear, if this clip were any more erotic you'd have to rent it from the curtained section of a video store. PROTIP: wear a trench coat and fake mustache.

Keep going for the whole video. Also, what's up with the video shake when they collide? Just how powerful was this?

Thanks to Randi, who informed me Gandalf did it first.

    Smoke rings create a bunch of smaller versions of themselves when they bump into each other in just the right way.

    after 17 years, we finally get to see what Static-X was talking about.

    My boner nudged the tripod while filming, it couldn't be helped.

    This must be how chemtrails are made. I promise to use the technology for e̶v̶i̶l̶ good.
