Description
Raindrops on Spider Web. After a rainstorm. A large spider web among wet leaves with water drops formed to create this subject. A spider web, spiderweb, spider's web, or cobweb is a structure created by a spider out of proteinaceous spider silk extruded from its spinnerets, generally meant to catch its prey.
If you go out after a rain, you may notice spider webs glistening with water droplets. The soggy webs resemble human-made meshes for fog collection: They both have thin fibers that collect water from droplets in the air. Researchers from Sogang University in Seoul, South Korea have developed a model to predict whether a falling droplet will stick to a thin fiber, and how much water residue will remain on the fiber. Using a syring and wire, they dropped water onto varying thicknesses of wire....When a water droplet hit the wire, one of three things happened: The droplet jiggled, but ultimately stuck to the wire, the droplet fell from the wire mostly intact, or the droplet split. For a droplet of a given size, the outcome is determined by how fast it's moving and the wire thickness.
