Lizard Helps Make Spiderman Suit Reality

Scientists at the University of Dayton have created a peel-on, peel-off glue which mimics the wall-climbing abilities of Spiderman. The substance, based on the feet of the Gecko lizard, is three times stickier than existing adhesives. The material is so strong that a 4?4mm pad would be enough to hold a 1.5kg object such as a hardback book. However, it’s likely too expensive for consumer use: one British scientist calculates that a single Post-it note using the glue would cost around a thousand dollars
