Wet Wonders Speed Around in Water Drops

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

The photos below were taken while photographing ordinary drops of pure, clean water falling against a dark featureless background.  In the first photo we see three water drops that each seem to have orbs speeding around inside them. The blue orb at the top has an unusual color.

On the same day I photographed the orbs below, one of which seems to be moving quite fast.
