SECRET OF SPIDER WEBS
Oxford
University has been doing research on spiders' webs and their electrostatic
properties. According to researchers, webs electrostatically reach out and grab
airborne particles, droplets, and insects. Webs are coated with electrically
conductive glue that make them attracted to charged particle – whether
positively or negatively charged. This causes the web to spring toward these
particles and collects airborne particulates and passing insects.
According
to lead researcher Fritz Vollrath, "Everything that moves through the air
develops static charge, so it's fascinating to see how spider webs use of this
to actively catch prey." In addition, the researchers state that spider webs
can also be used to track pollutants such as pesticides, because these particles
become trapped as well.
