After 69 years, one of the longest-running laboratory investigations in the world has finally captured the fall of a drop of tar pitch on camera for the first time. A similar, better-known and older experiment in Australia missed filming its latest drop in 2000 because the camera was offline at the time. The Dublin pitch-drop experiment was set up in 1944 at Trinity College Dublin to demonstrate the high viscosity or low fluidity of pitch — also known as bitumen or asphalt — a material that appears to be solid at room temperature, but is in fact flowing, albeit extremely slowly. It is a younger and less well-known sibling of an experiment that has been running since 1927 at the University of Queensland in Brisbane, which Guinness World Records lists as the world’s longest-running laboratory experiment (see: Long-term research: Slow science). Physicist Thomas Parnell set it up because he wanted to illustrate that everyday materials can exhibit surprising properties. In the past 86 years that experiment has yielded eight drops, with the ninth drop now almost fully formed and about to fall." http://smp.uq.edu.au/content/pitch-drop-experiment http://www.youtube.com/watch?feature=player_detailpage&v=Les39aIKbzE Edited July 18, 2013 by alocispepraluger102 Quote
alocispepraluger102 Posted July 18, 2013 Author Report Posted July 18, 2013 ontinuously running film cameras would have taken care of the australian 'miss' and also created jobs for starving scientists developing film. why develop film when you know that the blob of tar hasn't dropped? Quote
