What happens when astronauts play with water in space?

Ever wondered what happens to water in space?

These astronauts aboard the International Space Station created this brilliant video to let everyone know.

They put a small camera inside a large bubble of floating water and filmed the amazing results.

In space because there is no gravity, a force called surface tension works on water and other liquids, making them float and come together into a sphere shape.

The video was filmed by Nasa astronauts Steve Swanson and Reid Wiseman along with European space agency astronaut Alexander Gerst.
