How Do Geckos Climb Walls Without Falling?

💡 The Answer

• Geckos have millions of tiny hairs called setae on their feet, which split into even smaller spatulae.
• These spatulae create weak molecular forces (van der Waals forces) that sum up to strong adhesion.
• The gecko can detach by changing the angle of its feet, peeling off like a sticky tape.
• This remarkable adaptation allows geckos to climb smooth vertical surfaces effortlessly.
