Sometimes the drop was witnessed to fall and the time recorded to the nearest minute, but other times, there was a span of time that a drop could have fallen such as during the night or work hours. Twelve drops were recorded falling over a three-week period of time. The setup was kept at a relatively constant room temperature, around 70 degrees F.
To test this idea, I had 245 grams of temperature-sensitive color-changing putty on hand from Crazy Aaron’s Thinking Putty 2 from another project and placed it in a funnel and left it to drip into a glass vase. It has been over a decade between the most recent drops falling.įor the science educator who wants to reproduce this classic experiment but does not have that kind of time to spare, an alternative would be to use silicone polymer, such as Silly Putty. 1 The experiment was started in 1927 when heated pitch, a viscous material derived from tar, was placed in a funnel and allowed to drip very slowly. The Pitch Drop Experiment housed at the University of Queensland in Australia is listed in the Guinness Book of World records as the world’s longest-running laboratory experiment.
