Pitch Drop Experiment Nears a Century of Patience
The Pitch Drop experiment at the University of Queensland, started in 1927 to illustrate pitch viscosity, is approaching its 100-year mark; drops have appeared after long waits (the first after eight years) and later intervals extended to 161 months, no one has ever seen a drop land, and the setup is expected to run for about another century with the next drop likely in the 2020s.
