Formation of 8 bubble like objects, with a cone shape.

Very visible at first, then went higher and higher until it disappeared. It stayed in a formation of 8 bubble-like objects with a short "tail". It was very clear at first (on the beach between 18th and 19th street). When I first saw it it appeared over the ocean and was very clear. It moved higher and higher and then disappeared. I watched it for about 10 minutes or so. I kept looking around to see if anyone else noticed it because it was really clear at first. But it seemed like people were just enjoying the beach and playing ball, etc. Unfortunately, it was a day that I didn't have my phone with me. I wanted to relax and "unplug" so I left my phone at home.
