Astronauts get to have all the fun.
During an expedition on the International Space Station this past summer, astronauts Steve Swanson, Reid Wiseman and Alexander Gerst had a little bit of fun with a waterproof GoPro, a 3D camera, some water and the lack of gravity.
The resulting video, below, should be viewed with red and blue stereoscopic 3D vision glasses, but the original video is equally out of this world (we had to).
