[Music] like a real life Spiderwoman she sprays strands of silk in one long continuous [Music] flow the threads fan out like a sail and drift on air currents blowing across the water every few seconds she crimps the strands together to stop them spreading too widely the breeze will do the rest blowing the threads into a single line and a 25 M bridge now she must reinforce her Bridge because her web will hang from it but there's something bouncing the line at the other end another Darwin spider is trying to take advantage of her hard work
she must deal with the Intruder [Music] headon the cut line is an inconvenience but no more than that with hooks on the tips of each leg she gathers in the thread [Music] it won't go to waste as she'll eat it [Music] later when it's all Reed in she sprays again out streams another 25 M bridging line [Music] how a spider no bigger than a thumbnail can produce so much silk so quickly has baffled [Music] scientists and it's no ordinary silk it's the toughest natural fiber on the planet tougher than steel and it needs to be
tough to span the wide river with the bridge Tor and the ground anchor in place it's time to construct her [Music] [Music] trap these spiders can build the world's largest orb webs up to 2 m wide a few hours from the first spray of bridging line the job is done
