Astronauts spend large amounts of time in space. I wonder what they do for fun. I would recommend floating flag football.
I can see it now. An astronaut is sailing toward the guy with the ball, but just before he grabs the flag the guy with the ball starts spinning and rolls out of the way.
This not only sounds like a fun game to play, it also sounds like a fun game to watch. NASA could use floating flag football to teach people about the space program and capture the interest of children all over the world.
