[Answer] What is a spider's web made of?

Step 1 : Introduction to the question " What is a spider's web made of? "

...

A spider web (sometimes called cobweb from the obsolete word coppe, meaning "spider") consists of special proteinaceous spider silk. To create such a unique device as a web, spiders extrude silk from their spinnerets (silk-spinning organs).

This can be interesting: Spider webs have existed for at least one hundred million years, as witnessed in a rare find of Early Cretaceous amber from Sussex, southern England. Insects can get trapped in spider webs, providing the spider with food. Not all spiders use webs as a method of getting nutrition, and some spiders don't create webs at all.
