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 ...

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 ...

In its most basic form, surface tension is the tendency of liquids to bead up rather than spread out because they are more attracted to themselves (cohesion) than they are attracted to other things, ...

The device sits on a side-by-side set of pontoon-like floats. Instead of using lipids for propulsion, though, it creates the surface tension imbalance via the controlled release of isopropyl alcohol.

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 ...
