Now this is very amusing !! Indian American astronaut Sunita Williams and her Japanese Colleague Akihiko Hoshide used a toothbrush to fix an important power unit in International Space Station(ISS).

The bolt cleaned by the toothbrush is the same one that had given both the astronauts much trouble during their spacewalk last week. They were unable to fix it then. After that incident there was a long discussion between the astronauts and NASA engineers on ground about how to fix the bolt and they indeed came up with a very unique solution of using toothbrush as a tool to fix International Space Station.

Well, whatever works!!
