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 ...

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 ...

What do dishwashing liquid and nonstick pans have in common? Besides the fact that one is used to clean the other after cooking, both household items derive their usefulness by affecting the physical ...

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 ...

Propelled by chemical changes in surface tension, microrobots surfing across fluid interfaces lead researchers to new ideas. Spend an afternoon by a creek in the woods, and you're likely to notice ...

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 ...
