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.
This link will take you to the 3D version of the video. Note: You will need red-blue stereoscopic 3D vision glasses to view the video.
These astronauts act like little kids doing a school science project.
