🤔 How it works …….. ⁉
How a spider makes web 🕸️🕷️
Spider has ability to transform liquid silk inside its special glands into solid threads. The spider does this by physically pulling the spider silk through its spinnnerets silk-secreting organs on its abdomen. Once the thread is started, the spider lifts its spinnerets into the breeze. It’s the breeze that is the secret to the spider’s ability to spin a web from tree to another.
Spider silk is very lightweight. Any slight breeze – even convection currents from a patch of ground warming in the sun – can carry the thread from tree to tree. Although the thread isn’t sticky or gluey, it can still stick to the tree. Most likely it just gets tangled on small protuberances. Or it adheres due to static electrical forces, like balloons sticking to a TV screen.At this point, the spider can use the thread to “tightrope walk” from one tree to another. Usually, the spider is hanging underneath the thread on its journey from tree to tree
And spiders recycle – some eat their old webs and use the digested silk to produce new ones. The breeze is the key to a spider’s ability to spin a web between two trees.
😳Why❓❓❓
Why sun appears reddish at sunrise and sunset…??
The light from the Sun travels through Earth’s atmosphere it undergoes scattering before it reaches us. … Thus, there is more probability for shorter wavelength light to get more scattered than for the longer wavelength light. Hence, the Sun (and sunrise and sunset) appears reddish orange during sunset and sunrise.
