Liquid surface tension has a straightforward definition with a dramatic job description: it’s the force that politely stops a liquid from flinging itself off into the universe.
Measuring it, however, is far less straightforward. There are multiple ways to quantify surface tension, and they can quickly turn an easy concept into a small maze of methods. To bring some order to the chaos, this article focuses on two main measurement approaches: drop-based techniques and force-based techniques.

When people are looking for a way to measure small amounts of moisture, we often recommend the Karl Fischer method.

At first glance, viscosity seems like a fairly simple concept. It helps describe how thick a product is, or how well it flows. That's all, right?
In reality, there are several different terms that come under the heading of viscosity. These terms are derived from how the viscosity is measured. When people talk about viscosity, they are talking about one of two things: kinematic viscosity or dynamic viscosity.
It's not easy to find a lot of information on the differences between dynamic and kinematic viscosity. This is my attempt to bring clarity to these two principal concepts.
