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 ...

Check out this video demo: So, that is just plain water. If I am careful, I can make that thin aluminum disk stay on the surface of the water. This is not the same as floating in Archimedes principle.

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 ...

Demonstrates basic principles of water, including surface tension, pressure, and buoyancy. It shows how water can hold more than its brim due to surface tension, how pressure increases with depth, and ...

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 ...

Researchers explain a new mechanism for ice formation. Ice can form near the free surface of a water droplet via small precursors with a structure resembling ice 0. These are readily formed by ...
