Water in Space Special for Shavuot
The jewish holiday of Shavuot has been also celebrate as a water festival, and it made us think: What happens to water in conditions of microgravity in space? How does it look like the International Space Station?
It is interesting to see how fluids behave in a situation where there is no gravity, or, to be more accurate, a constant state of free fall. This physical condition is called Microgravity, an environment of a moving spaceship around the Earth, such as the International Space Station. Everything inside in the space shuttle is in a constant state of free fall, which allows micro-gravity conditions.
- Water in space look like floating balls of liquid inside the space station, as opposed to its liquid state on Earth. Watch

The commercial was created in the summer of 1997 in the Soviet Space Station. It was reported all over the world about the first ever commercial in space for Israeli milk, and it made it into the Guinness Book of Records.
