Everyone knows what imponderability means but far not all of us can experience this amazing state of being absolutely weightless. The only lucky people who know what it's like are astronauts, so they don't only enjoy this state but also carry out some experiments. This time they dissolved an effervescent tablet in a floating ball of water and made some pictures with the help of a camera capable of recording four times the resolution of normal high-definition cameras. Such devices give scientists an irreplaceable tool aboard the space station. Watch what these cameras are capable of and enjoy the beauty of zero gravity!
