Lotus effect

The Lotus effect describes how lotus leaves stay clean because of their unique surface structure. Tiny bumps and waxy layers on the leaf create a super-smooth, water-repellent surface. When water lands on it, droplets bead up and roll off, taking dirt and dust with them. This natural self-cleaning property helps the plant stay clean without the need forwashing. Scientists mimic this effect to develop water-resistant materials and coatings for clothing, buildings, and other surfaces, making them easier to keep clean and resistant to water damage.
