Spiders are among the most fascinating creatures on our planet. Their bizarre web constructions leave us in awe. There are many different types of constructions among them. The webs are intricately built and equipped with all sorts of signal and trip lines, traps, and some even have trapdoors. The fine silk threads of the webs are characterized by extreme strength and enormous elasticity. For a long time, humans have looked to spider silk and webs for inspiration in the development of technical constructions. The tenth volume of our non-fiction series under the motto "Ask Nature" presents many web constructions of spiders and provides information on important technical implementations. Simple models and interesting experiments allow readers to gain a deeper insight into technical transmission possibilities.
