PITTSBURGH (KDKA) -- If you think about it, water can be kind of weird. It can be a liquid, a solid or a gas. It contracts when it is cooled to a certain point, then starts to expand as it gets closer ...

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 ...

The paper clip is on the water but is not floating like a boat which is less dense than water. The paper clip is more dense than water but can rest on the surface of the water because of the water's ...

A tensiometer is an instrument used to measure the surface tension (γ) of liquids or surfaces in the domain of physics. Surface tension is the contractive quality of the surface of a liquid that ...

Fill water dropper with water Add one drop at a time onto the penny Watch what happens EXPLANATION: Have you ever seen a bug walk on the water? This is because of surface tension! Water is what we ...

Researchers have shown that surface tension on a solid material is unconnected to the energy required to create a new surface. Consequently, surface tension on a solid does not exist in its ...

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 ...

Our readers agree that the world would be a very different place if water displayed no surface tension, making life on Earth ...

Inspired by the surface tension of a droplet of liquid, researchers have created an adjustable wheel that alters shape in real-time, tackling uneven surfaces and high obstacles with ease. It’s opened ...

Bonding over the science of Surface Tension! Why do some things float in water while others sink? The Crew’s depth of knowledge goes WAY below the surface, as they learn all about the molecular bonds ...
