the Ig Nobel Prize in physics, a parody of the Nobel Prize, for the pitch drop experiment. Mainstone subsequently commented: The experiment is monitored by a webcam but technical problems prevented the November 2000 drop from being recorded. The pitch drop experiment is on public display on Level 2 of Parnell building in the School of Mathematics and Physics at the St Lucia campus of the University of Queensland. Hundreds of thousands of Internet users check the live stream each year. Professor John Mainstone died on 23 August 2013, aged 78, following a stroke. Custodianship then passed to Professor Andrew White. The ninth drop touched the eighth drop on 17 April 2014; however, it was still attached to the funnel. On 24 April, Professor White decided to replace the beaker holding the previous eight drops before the ninth drop fused to them (which would have permanently affected the ability of further drops to form). While the bell jar was being lifted, the wooden base wobbled and the ninth drop snapped away from the funnel. In mid-March 2018, the live feed was interrupted due to technical problems in the experiment's webpage. Since mid-October 2020, the live feed is back online on the experiment's webpage. Timeline Timeline for the University of Queensland experiment: After the 7th drop, air conditioning was installed, lowering the average temperature. 12 April 2014: 9th drop touched 8th drop; 24 April 2014: 9th drop separated from funnel during beaker change. Trinity College Dublin experiment The pitch drop experiment at Trinity College Dublin in Ireland was started in October 1944 by an unknown colleague of the Nobel Prize winner Ernest Walton while he was in the physics department of Trinity College. This experiment, like the one at University of Queensland, was set up to demonstrate the high viscosity of pitch. This physics experiment sat on a shelf in a lecture hall at Trinity College unmonitored for decades as it dripped a number of times from the funnel to the receiving jar below, also gathering layers of dust. In April 2013, about a decade after the previous pitch drop, physicists at Trinity College noticed that another drip was forming. They moved the experiment to a table to monitor and record the falling drip with a webcam, allowing all present to watch. The pitch dripped around 17:00 IST on 11 July 2013, marking the first time that a pitch drop was
