Spiderman toy stuck to a glass ceiling. The 40 gram figure has a 0.5 centimetre square piece of 'gecko tape' on its hand. In 2000,a team in California discovered that geckos are equipped with billions of tiny hair-like structures (spatulae) on each toe. Intermolecular forces (van der Waals) are produced by the hairs,allowing geckos to climb. In 2003,Professor Geim's team at Manchester University produced a sticky tape,which mimicks the action of spatulae. Plastic pillars,only two thousandths of a millimetre tall,are attached to a flexible base so that the 'hairs' come into contact with the smallest undulations on a surface | |
