Rain fall onto leaves of plant which are super hydrophobic.Rain droplet roll and pick up dirt and fall down. https://www.canadelectrochim.net/apps/photos/photo?photoID=193149138 193149138 Transition from hydrophobic to hydrophilic state Transition from super-hydrophobic to super-hydrophilic state induced by light energy. https://www.canadelectrochim.net/apps/photos/photo?photoID=193149139 193149139
