This was near the Ross Island Bridge during the Fire work show on the fourth of july. I noticed one green light ascending and at first i thought it was a fire work, but it never popped, it just hovered, for a long time. then one more joined, and another. and they were making a straight inferred line, one on top of another, and also a triangle when the third one came. more and more kept popping up the more the show went on. a helicopter went by, and something that looked like a drone, but it was so high. and one followed an airplane like it was a fly and then went back to where it was with the other object. people around me watching the fire works also noticed these strange orbs and were talking about them. the more i stared it looked like there were tiny clear dots going in and out of the object. they also changed colors from green to red, to clear to green.
