ALT Did you know that scientists are studying how geckos can walk on walls and even hang from ceilings? 🦎🪜 Geckos have super sticky feet that allow them to cling to surfaces without any glue or suction cups. The secret behind this amazing ability is millions of tiny hair-like structures on their feet called "setae." These setae create a special force called "van der Waals force" that lets geckos stick to all sorts of surfaces. Inspired by gecko feet, engineers are working on creating materials with similar properties. Imagine if you could climb walls like a gecko or stick things together without using tape! Scientists are learning from nature to design innovative materials that could have lots of useful applications in the future.
