The Pitch Drop is the world’s longest running lab experiment. Many believe it’s also the most boring. But in its 86 years, no one has seen a Pitch Drop fall.
Now the 9th drop is set to go and anyone watching has a chance at history….
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…. Professor Andrew White is the Pitch Drop’s new custodian.
