How do spiders react to alcohol?
It was hypothesized that alcohol would have a deleterious effect on the number of radii, number of cells, and area of cells in the webs of orb weaving spiders. Spiders tended to spin webs more quickly after alcohol consumption, and often ripped holes in the webs.
Why do spiders spin their prey?
The main reason spiders spin webs is to catch their dinner. When an insect, such as a fly, flies into a spider’s web, it gets stuck on the sticky threads.

How does a spider make its web?
Every morning just before dawn, the spider makes the web in 20-30 minutes by laying down radii at set intervals and then crossing the radii in pendulum and round turns to lay the insect-catching zones. Then it settles down at the hub with its eight legs spread on he radii to pick up the vibrations from a captive.
Did you know that stoned spiders make deformed webs?
