To quote the late, great author Douglas Adams, space “is big. Really big. You just won't believe how vastly, hugely, mindbogglingly big it is.” So naturally, the astronauts of Expedition 40 to the International Space Station decided to explore that bigness by learning about water surface tension in microgravity. To put it in layperson’s terms, they made a softball-sized bubble out of water, stuck a GoPro inside and played with it.
One can assume that there’s plenty to learn about properties of physics—and therefore, unlocking the secrets of the universe—in this experiment, but to most of us, it just looks like they’re having an enviable time with a big water bubble in space. Either way, good for them.
And if you have a pair of red-and-blue anaglyph glasses, you can watch it in 3-D here:
