During Expedition 40 in the summer of 2014, NASA astronauts Steve Swanson and Reid Wiseman — along with European Space Agency astronaut Alexander Gerst — explored the phenomenon of water surface tension in microgravity on the International Space Station. The crew “submerged” a sealed GoPro camera into a floating ball of water the size of a softball and recorded the activity with a 3-D camera. (Video: NASA)

Note: You will need red-blue stereoscopic 3D vision glasses to view the video.

Bottom one is the 3D version, in case you couldn’t figure that out.

The big question for me is how my brother Steve kept being an astronaut a secret all these years.
