The “pitch-drop” experiment has been running continuously at the University of Queensland since 1927 (http://

www.physics.uq.edu.au/physics_museum/pitchdrop.shtml).

In this experiment, a funnel pitch is being used to measure

the viscosity of pitch. Flow averages at about one drop—per

decade! Viscosity is calculated using the volume flow rate
