of jumping spiders and post-it notes

Andrew Martin, from the Institute of Technical Zoology and Bionics in Germany, said, "We found out that when all 600,000 tips [of the spider's foot] are in contact with an underlying surface the spider can produce an adhesive force of 170 times its own weight. That's like Spiderman clinging to the flat surface of a window on a building by his fingertips and toes only, whilst rescuing 170 adults who are hanging on to his back!"
