Mexico yellow orb releases numerous child orbs!

This recent video from Mexico is truly astounding, and I am at a loss how these could be explained away. It's got lots of reference points in continuous video, and shows multiple self-luminous objects zipping about clearly under some sort of control. Furthermore, scores of these luminous objects appear to come from the central object, and even those that don't simply appear from out of nothing! Really neat stuff. How come Mexico gets all the nifty ones? ;)
