Fresh Air Photo Thursday, September 17th

Fabulous photography courtesy of Steven in Grande Prairie with honourable mention going to Heather and Levi. Steven tells us the insects love their front porch — and adds: “that is good for some, not for others”. How true! But somebody in Grande Prairie may have stepped on one of spidey’s relatives, because rain is on the way.
DID YOU KNOW? The way a spider constructs its web is the envy of engineers everywhere. Here’s how it happens: Web-building spiders have glands in their abdomens that produce liquid silk. Each gland has a tube to the outside of the hind end of the spider called a “spinneret.” She will press the spinnerets against some object, adhering the liquid silk to it. As she moves away, a silken thread forms and as she ejects more of this substance, web construction begins.
Check out this website I found — it has an animated movie showing how a web is made. Give it a click:

Scientists believe that if they gathered the same weight of spider web as a piece of steel, the web would be much stronger than the steel! But as hard as they try, they cannot match or copy the silk.
