Spiders spin silk using special parts in their bodies called spinnerets, like tiny thread machines. Their silk is super strong because it's made of a special protein that can stretch and hold on tight, almost like magic glue!
How It Works When a spider wants to make a web, it pulls out long threads from its body and weaves them into [patterns](/search?q=patterns). These threads are made of something called spidroin, which is kind of like super-strong sticky string.
Examples
- A spider spins a web like a weaver using thread from its body.
- Spider silk is so strong that it could hold up a small car if it was big enough!
- The sticky parts of the web help catch insects, just like glue.
