How do spiders make a web?

You asked us a question. How do spiders make a web?
 
All spiders can spin silk. But only some of them use it to make webs. When you think of a spider web, you're probably imagining something along the lines of this. Right? (Points to a web.) 

That particular kind of web is the handiwork of orb spiders. They start by sending out on the wind a line of silk. It's called a bridge thread. They have the desperate hope that it will catch on to something.
 
Once that's locked down, they get to work on the main structure of the web. It ends with a spiral.
 
Now this is where things get a little bit sticky. Literally. The spider uses that spiral as a guide for laying down a new superglue spiral. Voila!  Now, all said spider has to do is sit and wait for the next meal to come along.
 
Amazingly, web-spinning spiders have the ability to tell the difference between the call of dinner and vibrations made by non-foodie things. Like leaves. If only the rest of us could be so discerning.
 
Did I just eat leaves?

    I found it interesting that this orb spider has a different way of using its silk. By catching its prey with its silk I mostly heard of spiders that just use silk as a web. It is very interesting how they just make a bridge with the silk and let it fly in the wind they are like little engineers.

    Its sticky because the spiders uses a spiral to guide for laying down a new super glue.

    Spider webs are sticky because they make them out of silk. Also they are sticky where they can catch fly and other animals to eat. That is why spider webs are very sticky and that is what they use there web for.

    Spider webs are sticky because the spider creates the web in order to capture bugs as their next meal. They need the web to be sticky so that the bug sticks to it."The spider uses that spiral as a guide for laying down a new superglue spiral."
    I think this article is really interesting at how a spider can create a web.

    The reason spider webs are sticky is because they need the sticky part to catch there food.
