Stock Photo Description:Water drop floating in space with person's face refracted stock photo. This is a photo by NASA Public Domain showing water drop floating in space with person's face refracted.
Even bubbles are more interesting in space. Here, a water bubble floats freely on the International Space Station, showing an image of Expedition 10 Commander Leroy Chiao. Chiao's picture is upside down because light is refracted, or bent, as it passes from one medium to another -- in this case, air to water. The same effect produces rainbows when light passes through raindrops in the air.
