WORLD WIDE WEB

-

The spider web is made from a liquid protein inside the spider’s body that hardens to polymer when exposed to air. Garden spiders build orb webs by putting their abdomen to the night air and emit webbing into the wind until it attaches to some distant thing.

They strengthen the first key strand several times, then use it as a highway between points, building a framework of sticky silk. Once the framework is in place, they begin spiral constructi­on, keeping in touch with the previous strand by a leg and thus maintainin­g the nearly perfect, structures that we admire in the morning dew.

The silk in a spider’s web is five times stronger than a strand of steel that is the same thickness and a web made of strands of spider silk as thick as a pencil could stop a Boeing 747 jumbo jet in flight. Scientists still cannot replicate the strength and elasticity of a spider’s silk

Apparently, different drugs affect the way spiders spin their webs. Studies have shown that spiders on LSD spin beautiful webs, while spiders on caffeine spin terrible webs. Something to ponder as you drink your morning coffee and plan the day ahead!
