It's not all science experiments and Aerosmith songs on the International Space Station; sometimes you've got downtime, and sometimes you fill that downtime by playing games. But what kinds of games do astronauts play?

The guys at Tested talked with Canadian astronaut (and up-and-coming Bowie impersonator) Chris Hadfield about the games he and his crewmates play aboard the ISS. Among them: Scrabble (with the pieces velcroed to the board) and… space darts. Hadfield demonstrates the darts, and then the Tested guys come up with some more games for him to play in low-grav.
