Editing Pitch drop experiment (section)

==University of St. Andrews experiment==
A pitch drop experiment was begun at the [[University of St Andrews]] in 1927, the same year as the Queensland experiment. No evidence has emerged of any contact between Parnell and the instigator or instigators of the St. Andrews experiment. The pitch in the St. Andrews experiment flows in a largely steady, but extremely slow, stream.<ref>{{cite web |url=https://www.uq.edu.au/news/article/1999/02/experiment-reaches-delicate-pitch |title=Experiment reaches delicate pitch |access-date=15 July 2022 }}</ref> At some stage (likely in 1984) St. Andrews professor [[John F.
