Why are spider webs waterproof?

Question

I once tried to rinse off spider webs with a water hose on the most powerful of settings, and does not work. I also notice they can withstand the most powerful of thunderstorms.

What is it about spider webs that are resistant to water?

Thanks to all who answer! :-)

Answer 1

I would say since the web is the only way of their survival, it had to be created that way. It's the oil holds them strong, and resists water. I wish our computer web was waterproof too.  :( Oh, btw, I use long branches to clean the webs.

Answer 2

it has some sort of chemical that the spiders release making it extra strong. I don't know how many know this but a lot of the bullet proof vest are made with the same stuff spiders make.

Answer 3

Interestingly enough, there are seven types of webs. Spiders can make several different types of webs because they have several spinneret glands. When erecting a web, some are silky, some are fluffy and some are sticky. I am guessing the ones you were trying to wash away were made of the sticky web. Well, actually, it is mostly sticky. Really, the spider can will weave non-sticky strands through out the web so that it can still maneuver around. Water is generally chemically neutral. The sticky webbing can almost be compared to glue or tape. It requires a higher PH substance to usually dissolve them such as spit to seal an envelope. Water does not have a high enough PH to weaken the sticky bonds that hold the water together, thus it will not wash the web away.

I hope that answers your question. :-)

Answer 5

why? because otherwise they would get all messed up, but if you mean "how?" then it's probably because they have oil on them or some kind of waterproof chemical
