Dark object triangular changed shape

I was excersicing yesterday outside with my hula Hoop. I noticed a dark object floating circulating and flying oddly not like a plane. At first it looked like a triangular plane, but it was not flying like a plane. It moved in circular and zig zag ways. My mom also saw it. I lost sight if it, and reappeared. She said to her it looked like paper debris. I was able to zoom-in very close to take screenshoot of it.
