Description
Where does the rain come from? Why do rivers flow? Demonstrate nature´s water cycle: Fill water into the sea and put some ice cubes into the cloud. Use a lamp which heats up as sun – and see what happens. The sun evaporates the seawater. The ascending vapour condenses at the cold cloud. It starts to rain. The rivers collect the rain water and transport it back into the sea. The cycle is closed. Content: relief basin, lid, cover for the cloud, stand (lamp is not included)
