Start in the middle of the space ship and swim your way to the edge by swimming through the air. It's a way to keep entertained on long interplanetary journeys. Help from exhaled propulsion is allowed and even encouraged

       This won't work as well as you think and can actually be quite dangerous. Hence why space habitats are designed to have very few spaces large enough for this to happen. Astronauts train for how to get out of this situation (see link). Chris Hadfield says really the only way is to rely on the ventilation system to gradually move you close to something you can grab.   

       I think this was a plot point in Ender's Game also.

       Are you claiming it won't work to inhale in one direction and exhale in another? Yes you'll mostly give yourself a spin, but it's an off-center spin that can be exploited.

       So each astronaut should carry a pair of folding Japanese fans?

       All of the above comments about prior art and impracticality are true, but in no way negate the principle of this new idea, of having a race. So [+]
