Space station astronauts grow a water bubble

During Expedition 40 in the summer of 2014, astronauts Steve Swanson, Reid Wiseman, and Alexander Gerst explored the phenomenon of water surface tension in microgravity on the International Space Station. The crew submerged a GoPro camera into a floating ball of water the size of a softball and recorded the activity. Take a look at their results! Credit to 'NASA'.
