Even though it looks like there is no gravity, Earth is still pulling on the space station. The astronauts float because they and the station are all falling together in a big circle around Earth. It is kind of like how you feel lighter on a roller coaster going over a hill, but in space that feeling never stops!
- In zero gravity, astronauts can do somersaults in the air any time they want.
- Water floats as wobbly bubbles instead of falling into a glass.
- Astronauts have to strap themselves into sleeping bags so they do not float away while they sleep!
