Here you can see three astronauts playing with a floating, softball-sized water bubble aboard the International Space Station.
That's been done before, but this time they put a sealed go-pro inside the bubble.
The result is this orbiting "bubblecam" that recorded the feat.
Astronauts made the video over the summer, to explore the phenomenon of water surface and microgravity, which comes about whenever an object is in freefall.
