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 ...

Jason Latimer from Impossible Science defies gravity with the surface tension of water. Jason Latimer from Impossible Science, together with Constance Zimmer and her daughter, shows how to defy ...

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 ...

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

Surface tension influences the fraction of atmospheric particles that become cloud droplets. Although surfactants are an important component of aerosol mass, the surface tension of activating aerosol ...

(CBS News) Let's go ahead and keep our focus on media that provide sustenance for the mind (with a dash of whimsy and fun!) rolling today. You've done a lecture on linguistics. You've done a hybrid ...

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 ...
