In 1944, a long-since forgotten individual at Trinity College in Dublin poured a blob of pitch into a glass funnel, allowed it a few years to settle, then cut a hole at the bottom to let the pitch drip out and fall. One drop falls per decade, but nobody has ever witnessed the drop actually fall. Until now.

The experiment sat on a shelf mostly ignored, until 2012 when Shane Bergin set up a web cam to monitor the experiment. The video shows the drop falling in two stages: dropping and then snapping off.

Researchers say the experiment demonstrates pitch is 2 million times more viscous than honey, 2 billion times more viscous than water, and 900 trillion times more boring than The Watchtower.
