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.
