In 1927, Professor Thomas Parnell heated a sample of pitch and poured it into a sealed funnel. Then, he waited.
As Atlas Obscura tells it, "Pitch is the name of a number of hard tar-like substances and in this case bitumen was used. Though at room temperature pitch appears to be a solid and can be shattered by a hammer, it is in fact a very high-viscosity liquid, and Professor Parnell wanted to prove it."
Between 1927 & 2009, the pitch has dripped eight times. If you don't have much else going on, you can watch the pitch live with a video player here.
This is a screen capture of the pitch earlier today. Better run check, eh? Looks ready to drop.
If the Super Bowl's not for you, you can attend this experiment live in person at the University of Queensland in Brisbane, Australia. Not in Australia? Take a tour here at EarthPhotos.com.
