Viscosity of Liquids
In this episode we will be racing liquids to test the viscosity of liquids. We use multiple liquids in our viscosity of liquids experiment and show you how to set up the liquid viscosity experiment and time our results to see which liquid has the highest viscosity and which has the lowest viscosity. The Viscosity of liquids can affect how they are used in science.
