Have you ever wondered how geckos can walk on windows and other smooth vertical surfaces without falling victim to the forces of gravity? Well, for these reptiles, it all has to do with the design of their feet!<\/p>\n

Gecko feet are designed to stick to things. They have millions of teeny tiny hairs on their feet called setae<\/em>. On each of these hairs, there are hundreds of thousands of pads called spatulae<\/em> that stick to surfaces. Although it might surprise you, these pads are not suction cups. Geckos are able to stick to these smooth surfaces because of something known as Van der Waals forces<\/strong>. A Van der Waals force is a relatively weak, electrical-like force similar to the electrostatic force you see when you take warm clothes out of a dryer without fabric softener and everything sticks together. They are also the reason that individual water molecules stick together in a glass of water. Each of the gecko\u2019s spatulae<\/em> is able to stick to the surface by brushing along a surface and creating a bond, which is broken when the gecko decides to take its next step. Because there are SO MANY spatulae<\/em> on a gecko\u2019s feet, this bond is 1000x stronger than what is needed to hold its weight. All these spatulae<\/em> are the secret behind a gecko\u2019s ability to hang upside down using one foot. <\/strong><\/p>\n

These amazing little setae<\/em> and spatulae<\/em> have got inventors\u2019 minds going. It is the inspiration for a new tape being tested, called Gecko Tape. This tape creates a stronger, tighter seal than any other tape. Who knows? Maybe one day you will be able to hang from the ceiling, just like a Gecko<\/p>\n","protected":false},"excerpt":{"rendered":"
