In grade school I used to collect spider webs like these. You take a can of hair spray and spray the web until is is saturated with hair spray. Then you bring up a piece of black construction paper behind the web. The sheet of paper and the web have to be perfectly parallel! Then you move the paper against and on through the web, breaking all of the anchor lines at the same time.
Done properly, you capture a beautiful spider web, suitable for framing. But, if you don't keep your paper parallel to the web and it hits at an angle, it will break through part of the anchor lines instead of all of them at once.
When some anchor are broken first, the whole web collapses!!! It's the shared tension of the anchor lines that keeps the web stable.
