Currently, these interactions are often modeled using analogs from fluid mechanics including viscosity and surface tension. "What we have shown is a fascinating new role for surface tension in the ...

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 ...

A small, flat piece of Styrofoam, at least about three inches by three inches (For example, this could be part of a take-out container or a sheet of packaging.) Utility or EXACTO knife and an adult ...

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 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 ...
