space rocket that runs on recycled milk bottles is being tested out by scientists which they hope will one day take us to Mars.Boffins at Polar Fusion in Bletchley, Buckinghamshire, even say that their bottle-powered rocket could one day be used for 'warp speed' travel to far-flung parts of the universe. The spacecraft is designed to work by heating up chunks of a high-density polymer, and then adding nitrous oxide.
