We have already seen some video or films which shows the state of zero gravity. But all we know that those video was made with the help of animation. Although those video shows the true nature of space still there is something missing. That is reality of space. Till now there was no any effect on space was filmed but one astronaut Chris Hadfield tried to made a music video in international space station ISS. You can watch the effect of zero gravity there. Guitar seems to flow in space. And Chris himself stand there as unusual way from the reference frame of earth. Watch this video here.
