You know the photo below, right? the earth in space?

Well actually, the image above is a photo of a water droplet, superimposed on a night sky background, cleverly reflecting a 2-d photo map of the earth from space.

Below is the actual photo, next to a photo of the studio setup where the photo was taken

These and other amazing photos (another earth-in-a-droplet that looks like a globe below) were taken by Markus Reugels, who has taught himself to be a photography expert in capturing liquids.
