A Floating Water Droplet
I came across this funny picture today on space.com.
It shows an astronaut in the International Space Station that let a blob of water float around, another one made a picture of it, just as it crossed the line of sight between the camera and the astronaut’s face. Thus the water formed a nice lens, showing a reversed image of the astronaut’s face.
Wouldn’t you love being in zero gravity some day? :p
