According to astronaut Chris Hadfield, verrrrrrry carefully. You can't exactly get rid of anything in the space station, so, when you're yakking, you've got to make sure that no stray bits get out of the bag. The Canadian International Space Station dweller demonstrates here. He'd also probably want me to say that there's no drinking in space.
