Orb Makes Very Sharp U-Turn

Photo date: January 14, 2015. Photographer: Mark Mahin.

The photo below was taken in Grand Central Station in New York.

Below is a closeup of the orb in the center.

We seem to see here a speeding orb making a very sharp u-turn. I have photographed orb motion similar to this many times in water drops, where we see orbs moving very quickly around the edges of water drops. See the posts labeled "orb centrifuge effect" for such posts. We never see motion like this with insects, birds or dust.  When flying animals turn , they never turn this sharply.
