The gecko's feet contain molecules that are attracted to the molecules on the surface.
Geckos are lizards which belongs to reptile group. They are found in warm climatic regions of the world. Geckos and some other animals can climb smooth surfaces because of presence of Van der waal forces of attraction between the molecules of gecko's feet with molecules of the surface. The force of attraction is generated due to fluctuations or differences in charge present in molecules of feet and that of surface. The charge fluctuations generally comes into sync and generate attractive force.
<h3>What are the features of Geckos ?</h3>
