    Surface tension - an effect within the surface layer of a liquid that causes the layer to behave as an elastic sheet. Thus, the surface of any liquid behaves as if it was covered by a stretched membrane. Surface tension is measured in units of force per unit length.

    Working in Engineering - Engineering is the application of science to the needs of humanity. This is accomplished through the application of knowledge, mathematics, and practical experience to the design of useful objects or processes. Professional practitioners of engineering are called engineers. Meet the engineers and see what they do.
