From Futurism :
Houston...we have a problem.
According to Russian media, one of the toilets on the International Space Station burst last week, sending gallons of fluid into the station that needed to be collected with towels by the astronauts.
Of course it was the AMERICAN toilet that burst...according to Sputnik News .
“Our colleagues at the [Tranquility module of the ISS] had an incident on Friday,” the source said. “Astronauts separated the water supply line and the liquid leaked. Over 10 liters of water leaked before the problem was fixed. The crew had to collect the water using towels.”
All joking aside, this has got to be one of the things you DON'T want to happen when in space.
Well, that and decompression.
