Watching the fourth of july fireworks and noticed the orbs, there were three of them two close together and one back farther and slightly lower. It as about a minute after the fireworks started and my husband and mother noticed too and then the people watching around us. Its Very loud because were where very close to where they were setting off the fireworks. I took a few photos on high speed burst and then switched to video. There had to have been 5 hundred people watching the fireworks that night.
