Deciding to GoPro where no man has gone before, three astronauts used a bottle of water and an ingenious camera trick to get a unique glimpse of how liquids behave in space.
This past summer on the International Space Station, astronauts Steve Swanson and Reid Wiseman of NASA and Alexander Gerst of the European Space Agency wanted to see how the surface tension of liquids is different in space than on Earth. Without gravity to pull liquids down, they naturally form a spherical shape in space. The footage, released earlier this week, was taken with a sealed GoPro camera nested inside a grapefruit-sized globe of floating water that they shaped with their hands:
If you have a pair of 3-D glasses, here's the three-dimensional version of the experiment:
