As much as we would like to explain the phenomena occurring in the video, we cannot; sorry we aren’t rocket scientist! The little we can tell you, however, is that [gravity + a high surface tension liquid (water) = water sphere].
In the video below, astronauts Steve Swanson, Reid Wiseman, and Alexander Gerst film the placement of a GoPro cam inside of a “water sphere” created on the International Space Station. What we like about the video is that the GoPro, which is waterproof, is placed inside of the water sphere to record the astronauts’ reaction to this amazing feat. Kind of crazy the different forms molecules can undergo when placed outside of their natural element, right?
