nasa wouldnt lie to us

Lies are a myth.

Yep, just as I thought. You don't know anything about optics, you said some things that were totally wrong, after some googling you realized you were wrong, and now you are in a corner with no options left and nothing left to say.
Glass and water are both denser than air and they both refract light, just at slightly different angles. A water prism would work just like a glass prism, the only problem with water is that it's liquid and has to be in some sort of a transparent container to have a specific shape.

some interesting facts here ^

12km is nothing.
