Spiders make silk in a part of their body called the silk gland.
The silk gland makes a liquid out of something called proteins.
The liquid goes into a large area called a sac where the silk liquid is saved.
When the spider wants to make the stringy silk, it squishes the liquid down a smaller tube.
This squishing makes the liquid start to turn harder because it is being squished so hard.
At the very end right by the spinnerets where the silk string comes out,
the silk liquid gets squished into a really tiny tube where it turns into the silky string that we see in spider webs.
