Zero-g double/bubble lens

We've all heard of gravitational lensing. How about this for "anti-gravitational lensing?"

From my friend, Phil Plait's, Bad Astronomy blog:

A light bending exercise... in space!

He does a nice job explaining the optics. This is a water blob floating in the zero-g environment of the International Space Station. But to spice things up, the blob was injected with air.

I'll pose a few more challenging questions for my physics-ly brawny readers.

1. Is a spherical water blob a converging or diverging lens?
2. Is an air bubble immersed in water a converging or diverging lens?
3. Ray diagrams?
4. Characterize both images: real or virtual?

But don't forget to take a moment to appreciate the grooviness!
