Detailed Solution

They shine because of total internal 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 we are looking. If we look towards the center of the bubble we can see right through it.
Hence, an air bubble in water shines because of the phenomenon of total internal reflection.
