The web is one of the amazing wonders of nature. It is at the same time a refuge for a spider, its “hunting trap”, a vehicle for settling by the wind, and material for weaving an egg cocoon.
The spider knows how to make a web quickly and reliably, secreting the sticky substance with special glands. Building his house, the insect pulls the frame, radical threads, and only after laying the supporting spiral thread weaves a sticky sticky net in a spiral, and at the end of the work bites the supporting thread. But the point is not in the technology of “weaving” and not in how to make a web, but in the “magic” of threads.
Features of spider threads help scientists
Braided threads have special properties. Their strength and elasticity are higher than those of silkworms. This is due to the high content of glue-like sericin protein. The threads also contain bactericidal substances.
The uniqueness of spider webs is especially evident in the hydrophilic surface, capable of attracting water molecules to itself . Indeed, many of you have observed an amazing phenomenon - how the morning dew is collected by the weightless, finest web. A photo showing this natural wonder can be found on the Internet. Large droplets are formed from many tiny droplets, each of which is several microns in size. The droplets, moving towards the nodules, are connected to each other, increasing in size.
It was this property that inspired scientists to experiment, and as a result of many studies, an artificial web was created. Chinese nanotechnologists have repeated a natural masterpiece. From the nylon fibers taken as a basis, a thread with an uneven structure was created - a flat surface alternated with different tangled thickenings. After laboratory experiments, they came to the conclusion that the resulting thread is similar to spider web and is able to condense water. The new invention is planned to be used to create materials that absorb excess moisture.
Web as an original landscape design of a summer cottage
Along with the special useful properties discovered by science, the web is a symbol. Think of a spider-man who can move in any direction, or the awesome effect of spider webs on Halloween. Improvising, you can refresh a dull country landscape with a bright spot of a home-made web. For many, especially children, this will turn out to be an unusual frightening surprise, very similar to a real spider home. How to make a web?
- Take two wooden stakes about 1.5 m high and dig them at a distance of about three meters from each other. This will be the basis for fixing our web.
- A cord 0.5-0.7 cm thick is fixed in three places - on the two peaks of the risers and on the ground in the middle between the posts.
- Then, radical web threads are attached to the sides of the resulting triangle.
- Starting from the core of the resulting circle, weave the threads, moving in a spiral and gluing them for radical strength.
There are many other ways to make a web. You can fix a spiral thread on radical knots, but not glue. Another way is to weave a web from separate circles that will not pass one into another. Change the color, while the white web will be more believable. Do not forget to craft the owner of the home - the spider. In any case, the originality of your handiwork will be appreciated by others, especially children.
