Walter the Water Molcule
Around the World in Thousand Years – that’s the fate of the water molecule Walter. It is another approach to explain the famous water cycle everybody learns at school – though less schematic: Walter changes shape from water to wapour to ice to snow, and he is always on the road to nowhere. Very slowly of course. The story backs ESA’s new science satellite CIMR which can monitor water in all its physical conditions all across our planet. The graphics have been drawn by talented, patient and beloved Lucia Fabiani from Rome, to whom I am much indebted for great drawing series over many years of our cooperation.
