Discover the amazing properties of water's surface tension as you make metal paper clips float on water. You'll learn about the forces that hold water molecules together and how insects like water ...

The surface tension of a liquid is a measure of the cohesive forces that hold the molecules together. It is responsible for a water drop assuming a spherical shape and for the effects of surfactants ...

Introduction Have you ever noticed on a rainy day how water forms droplets on a window? Why does it do that instead of spreading out evenly over the whole surface? You might not guess it but this ...

This viral video posted on Instagram by the International Space Station shows how water shapes itself into spheres when it is in the microgravity of space. It is always interesting to watch ...

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 termed ...

Leafy inspiration: this artificial surface with 3D ratchet structures enables liquids of different surface tension to move in different directions. It was inspired by Araucaria leaves, which are also ...

Introduction Water. You can drink it, splash it, dive into it, float things in it. But it has its strange side: it flows, but then on some surfaces, it won’t flow, it’ll just roll up into a little ...
