I'm happy when I see astronauts happy. There's something about seeing people in space enjoy all there is about space that's just infectious. Even the little things, like playing around with a giant water bubble blob. I mean, I would do the same thing they're doing. Let it swallow my hands while a GoPro is inside.
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.
