To explain this, scientists proposed that the droplet eventually outruns the air and comes in direct contact with the surface. But observing that proved to be very difficult—until now, that is.

This droplet of water describes a near-perfect sphere. It does this because the surface of the leaf does not allow for a lot of wetting. Wetting isn’t just the thing that occurs with blue liquid ...

Why does a water droplet, dropped on a flat surface always take a round shape and not any ... This inward pull operating on the surface molecules tends to give the minimum surface area to a liquid.

The surface of a water drop curves outward to make a dome. This outward, or convex, curvature bends light rays inward. The result is an enlarged image on the retina of your eye.

Have you ever seen a water droplet bounce off the surface of a glass of water? Here's what it looks like at 2,000 frames per second -- and why it could help us build a smarter boat.

We are all familiar with the basic characteristics of liquids, particularly water. When we place a droplet of water on a surface, it will interact with the surface, often spreading in what is ...
