In use, the tube is filled different viscous liquids and the O-rings arranged at even, measured intervals down the tube. Ball bearings can be dropped into the liquid and timed over the measured distances with a stop watch to allow the idea of terminal velocity to be explored as well as the concept of different viscosities.
