Old ways are best
[PopularMechanics] One of the dangers of floating in a space station is that you really have to worry about leaks. After all, there’s only a thin metal shell standing between you and the vacuum of space, and even a small hole can quickly prove disastrous.

That’s the reality the astronauts aboard the International Space Station awoke to yesterday, when it was discovered that a small leak in the station was causing the air pressure inside to drop. Fortunately, the hole was small enough that it wasn’t life-threatening, and one of the astronauts simply plugged the hole with his finger while waiting for a more permanent fix.
