World’s Slowest-Moving Drop Pitched in Camera

World’s Slowest-Moving Drop Pitched in Camera

It's been a long time that a drop of tar pitch had not been captured on camera. Now it has been finally captured. After 69 years of experiment, the researchers in the laboratories of the world have finally captured it. This has been done under Pitch-drop experiments. It involves heating a sample of pitch and eventually pouring it into a sealed glass funnel.

It started with a Dublin pitch-drop experiment. It was established in 1944 at Trinity College Dublin. Aim of the experiment was to demonstrate the high viscosity or low fluidity of pitch. This material is dubbed as bitumen or asphalt. Scientists explain that it is a material that appears to be solid at room temperature but flows slowly.

It is one of many experiments that have been taking place from 1927 at the University of Queensland in Brisbane. This experiment has been part of the Guinness World Records lists. It has made a record under the heading of the world's longest-running laboratory experiment.

In the curiosity of demonstrating that everyday materials can exhibit surprising properties, physicist Thomas Parnell had established a laboratory. In the past 86 years, the experiment has resulted in nine drops. This was the recent one which is now fully formed and has been captured in the camera.
