Extra: You could repeat this activity but test substances other than detergent to see whether they affect the surface tension. For example, you could try different soaps, toothpaste, vegetable oil ...

Surface tension is important in many natural processes, including allowing trees to carry nutrients from the roots out to the branches and water skimmers to walk on the surface of water. Mixing it up: ...

The water molecules at the surface are attracted to the charged end of the detergent molecules. As the surface water molecules are attracted outward, this acts against their inward attraction that was ...

It is revealed, for example, in the floating of some objects on the surface of water, even though they are denser than water, and in the ability of some insects (e.g. water striders) to run on the ...

Key concepts Physics Cohesion Surface tension Hydrophobic. Introduction Water. You can drink it, splash it, dive into it, ... you can see a great example of surface tension in action.

Its surface tension. Let me show you before I explain. ... In a glass of water, for example, you have a bunch of water molecules. Water molecules form bonds with nearby water molecules.

Physicists at the University of Liège have succeeded in sculpting the surface of water by exploiting surface tension. Using 3D printing of closely spaced spines, they have combined menisci to ...

Surface tension is an effect within the surface layer of a liquid that causes the layer to behave as an elastic sheet. It is the effect that allows insects (such as the water strider) to walk on ...

Surface-tension gradient in thin films explains why foams unexpectedly form. Skip to content ... Let's look at a simple example. A mixture of soap and water will support a foam.
