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.
How amazing is it to see the water floating at Zero Gravity. The water assumes a roughly spherical shape because the surface tension keeps it from scattering around the space station in tiny droplets.
