Editing Pitch drop experiment (section)

==National Museum of Scotland experiment==
Another pitch-in-funnel demonstration was begun in 1902 by the [[Royal Scottish Museum]] in [[Edinburgh]] and is in Edinburgh at the Royal Scottish Museum's successor institution the [[National Museum of Scotland]].<ref name="nms_experiment_cat_entry">{{cite web|url=https://www.nms.ac.uk/explore-our-collections/collection-search-results/?item_id=205915|title=Apparatus / fluidity / pitch|website=National Museums Scotland|access-date=May 5, 2023}}</ref> The known records of its behaviour are incomplete: it is known to have dripped once at some time between 4 and 6 June 2016 and on at least one occasion in the past, but the time and number of the previous drip or drips is unknown. Furthermore, the June 2016 drip happened shortly after the experiment was taken out of museum storage, and the physical movement may have caused it to drip at that time.<ref name="nms_experiment_story">{{cite web|url=https://www.nms.ac.uk/explore-our-collections/stories/science-and-technology/made-in-scotland-changing-the-world/scottish-science-innovations/pitch-drop-demonstration/|title=Pitch drop demonstration|website=National Museums Scotland|access-date=May 5, 2023}}</ref>
