The flow of four different liquids from four pipets is started simultaneously to test their viscosity.
First step of experiment C of "Like Dissolves Like"
Four funnels are connected to differing lengths of capillary tubing. The greater the length of the capillary tube, the longer it takes for the water to flow through the apparatus.
