Watching "Pitch" drip is much more time consuming.
"In 1927 Professor Parnell heated a sample of pitch and poured it into a glass funnel with a sealed stem. Three years were allowed for the pitch to settle, and in 1930 the sealed stem was cut. From that date on the pitch has slowly dripped out of the funnel - so slowly that now, 80 years later, the ninth drop is only just forming." http://smp.uq.edu.au/content/pitch-drop-experiment
