Last year, I took a trip to Missouri for work. As always, I went to the St. Louis Zoo because it’s a pretty awesome zoo. What I did not anticipate was that 1) the zoo would close early … at noon … to prepare for a big event and 2) that it would be pouring rain. Now, I was prepared for the rain because I always keep a camera raincoat in my bag, so my camera was kept nice and dry. Camera rain coats work by using an extremely tight weave of ripstop nylon that is treated with a water repellent.
Ducks stay dry by using an extremely tight layering of feathers coated with a thin layer of oil that serves as a water repellent.
Humans stay dry by having the good sense not to go out in the rain.
I got thoroughly soaked and it took me a good two hours for my clothes to dry out.
