Answer 2

They shine because of total reflection. The speed of light is faster inside the air bubble than in the water. Thus the light gets reflected away from the bubble around the outside, looking like a mirror. This is only along the outer circle in the direction you are looking. If you look towards the center of the bubble you can see right through it.
