When asked by Hoda Kotb on The Today Show if shed ever consider going barefoot on the red carpet, Kelly admitted she wouldnt dare to. get overexplored and lose their relevance. Those toes that maintained contact with the surface were able to shift orientation and better distribute the load. Setae are also ultraflexible. Although the scientists have tested only minute amounts of the material, they estimate that if its properties hold up on a larger scale, a dime-size patch of it could support 2 to 22 pounds, depending on how densely the hairs were packed. [2] When a gecko is climbing on a hydrophilic surface, capillary forces combine with van der Waals forces to keep the gecko in place.
