Answer:
Researchers have developed a super-adhesive material inspired by geckoes. The illustrations show: a) a gecko, gecko foot and gecko setae and spatulae. b) carbon nanotubes with nanotube 'spaghetti' on top. c) a 650 gram bottle of cola hangs suspended from a 4x4 mm tape of nanotubes on a glass plate. d) a 150 gram stainless steel ring hangs from the same 4x4 mm tape of nanotubes on sandpaper. (Illustration: Science/AAAS)

“A gecko's foot has lots of tiny hairs, which are able to get into all the microscopic surface irregularities. This gives the gecko a very large surface area of foothold, where it can exploit the weak forces of cohesion that actually bind materials physically together,” explains Lenau.
