Das Pitch Drop-Experiment läuft seit 86 Jahren und beweist, dass es sich bei Pech (oder Teer) eigentlich um eine Flüssigkeit handelt. Im Verlauf der 86 Jahre sind bereits 8 Teer-Tropfen runtergefallen, nur hat das niemand beobachtet und das Experiment ist vom Pech (!) verfolgt: „In 1988 a drop fell when Professor Mainstone left the experiment for five minutes to get a drink. In 2000 the Pitch Drop was on webcam surveillance – but the camera failed and the drop fell.“

Jetzt haben sie eine neue Webcam in höherer Auflösung online gestellt, mit der man mit ein bisschen Glück dem Teer beim Tropfen zusehen kann, das Projekt The Ninth Watch entstand in Gedenken an Professor John Mainstone, der das Experiment 52 Jahre lang geleitet hatte und im August verstarb, ohne einen Tropfen Pech zu sehen:

The University of Queensland is offering people around the world the chance to add their name to the world's longest running laboratory experiment, the Pitch Drop. The experiment was established in 1927 to demonstrate the high viscosity of pitch, which looks like a solid but behaves like a fluid over an extended timeframe.

The Pitch Drop Experiment is basically a lump of pitch in a glass funnel. Eight drops of pitch have fallen in 86 years, but no-­one has ever seen one fall. A new website, theninthwatch.com, will log watchers from all time zones to record who is logged in when the ninth Pitch Drop falls. With signs of the stem narrowing, the ninth drop is set to fall at any time.

The Ninth Watch is dedicated to Professor John Mainstone, who was Pitch Drop custodian for 52 years until he died in August without seeing a drop fall.
