NEW GECKO ADHESIVE

It is a great discovery; this new adhesive, made of polypropylene microfibers, developed at the University of California at Berkeley, may be the closest man-made material to match the remarkable gecko toe hairs that allow the tiny lizard to scamper along vertical surfaces and ceilings. Two square centimeters of this material can hold 400 grams (0.88 pounds) weight, vertically bound to a smooth, clean, vertical surface. At the same time, the adhesive easily lifts off with minimal force, leaving no residue.
