I was teaching a camp at the school where I work. I was taking the students out for recess when one of the kids ran up to me asking what those things in the sky were. He pointed to the north and I saw five objects flying. They were in formation, and started to move faster when I saw them. At first sight, I thought they might be helicopters, but I didn't see any chopper blades, and they were really bright. They were reflecting sunlight, looked like they were chrome. From my distance, they looked spherical. They were moving north east. As the formation moved, some of the individual orbs were moving back and forth quickly.I was in complete shock. I tried to get my phone out to take a picture, but I didn't have time before they passed behind the school building out of my vantage point.
