For surface tension, something different is going on. There is an interaction between the molecules in the water and the aluminum (and between other water molecules).

Physicists at the University of Liège have succeeded in sculpting the surface of water by exploiting surface tension. Using ...

WHEN the available experimental values of the surface tensions of liquid metals are plotted against the reciprocals of the corresponding atomic volumes, the accompanying diagram is obtained. The ...

60-year-old definition of surface tension on solids revised Date: February 27, 2012 Source: Technical Research Centre of Finland (VTT) Summary: Researchers have shown that surface tension on a ...

But soap has a lower surface tension, so there is a difference in surface tension between the areas of high and low soap concentration. This drags the water back into the film.

In this activity you will see how soap decreases the surface tension of water by putting water droplets on top of a penny. Materials. Penny. Medicine dropper or eyedropper. Glass, ...

This gives plain old water a high surface tension. In fact, it's too high to allow big bubbles to form. When a soapy dish detergent is added to water, it lowers the surface tension so that bubbles ...
