Interesting experiment.. It does look like they are going to them. Keep experimenting and let us know what happens.
I just read that orbs are seen in the Brown (?)mountains in North Carolina and are often in one area near a swamp. It seems there is some kind of attraction for them there. When they have actually gone to reach and touch one the person felt something like an electrical shock so there must be a form of energy connected to them. Try and blow up one of your pictures and see if you can see any faces in the orb itself. You have a good observations though.
