Spider Silk



 Well it's now Tuesday and that means it is indestructible stuff day today's stuff is spider silk.

If you have every walked into s spiderweb you will know it is super sticky and stretchy and of course strong. 

All spiders make silk to do useful jobs such as spinning webs, wrapping up prey, dangling from ceilings and carrying eggs and it's one of the toughest natural material there is.

Because it is so tough, spider silk can be very useful to us as well, with it we can make things such as ropes, clothes and parachutes.

Spiders make silk as liquid inside their bodies, it forms strands as they push it ou from their abdomens.

This natural wonder has many cool properties, it's tough but light, some say weight for weight it's harder then steel.

It is incredibly elastic stretching up to four times it's original length without breaking.

It gets stronger when it is wet, helping spiderwebs hold up under heavy drops of dew.

It keep its strength and stretchiness even at extreme low and high temperatures.

The spiders with the strongest silk are Darwin's bark spider and the golden orb weaver, which spins a gold coloured silk.

  6. The gold one is cool. Never knew that. I know it's amazing stuff, but it doesn't stop me from waving mail and packages in front of me in the hopes of knocking them down on my way to the doors of people's homes.

    No one likes a mouthful of web.
