UFO Sighting in Michigan on July 4th 2015 – Bright red orange ish orbs ascending & descending becoming one then branching out into multiples

While observing the fourth of July fireworks, me & a couple others noticed bright red orange ish orbs appearing & disappearing along with what seemed like large clear oval disc shaped bubbles that seemed to appear alot closer to us than the orbs were...this lasted for about an hour or so. After the fireworks were over these strange orbs & bubble like formations disappeared.
