I'm not waiting around for this. 😆
The experiment demonstrates the fluidity and high viscosity of pitch, a derivative of tar that is the world's thickest known fluid and was once used for waterproofing boats.
Thomas Parnell, UQ's first Professor of Physics, created the experiment in 1927 to illustrate that everyday materials can exhibit quite surprising properties.
At room temperature pitch feels solid - even brittle - and can easily be shattered with a hammer. But, in fact, at room temperature the substance - which is 100 billion times more viscous than water - is actually fluid.
In 1927 Professor Parnell heated a sample of pitch and poured it into a glass funnel with a sealed stem. He allowed the pitch to cool and settle for three years, and then in 1930 he cut the funnel's stem.
Since then, the pitch has slowly dripped out of the funnel - so slowly that it took eight years for the first drop to fall, and more than 40 years for another five to follow.
Now, 87 years after the funnel was cut, only nine drops have fallen - the last drop fell in April 2014 and we expect the next one to fall sometime in the 2020s.
The experiment was set up as a demonstration and is not kept under special environmental conditions - it's kept in a display cabinet - so the rate of flow of the pitch varies with seasonal changes in temperature.
The late Professor John Mainstone became the experiment's second custodian in 1961. He looked after the experiment for 52 years but, like his predecessor Professor Parnell, he passed away before seeing a drop fall.

This is so stupid but funny also. 💩
When NASA astronauts return to the Moon through Artemis, they will benefit from decades of innovation, research, and technological advancements. We’ll establish long-term lunar science and exploration capabilities at the Moon and inspire a new generation of explorers—the Artemis Generation.
Meet the Space Launch System rocket, or SLS. This next-generation super heavy-lift rocket was designed to send astronauts and their cargo farther into deep space than any rocket we’ve ever built. During liftoff, SLS will produce 8.8 million pounds (4 million kg) of maximum thrust, 15 percent more than the Saturn V rocket.
SLS will launch the Orion spacecraft into deep space. Orion is the only spacecraft capable of human deep space flight and high-speed return to Earth from the vicinity of the Moon. More than just a crew module, Orion has a launch abort system to keep astronauts safe if an emergency happens during launch, and a European-built service module, which is the powerhouse that fuels and propels Orion and keeps astronauts alive with water, oxygen, power, and temperature control.
Orion and SLS will launch from NASA’s Kennedy Space Center in Florida with help from Exploration Ground Systems (EGS) teams. EGS operates the systems and facilities necessary to process and launch rockets and spacecraft during assembly, transport, launch, and recovery.
The knowledge we've gained while operating the International Space Station has opened new opportunities for long-term exploration of the Moon's surface. Gateway, a vital component of our Artemis plans, is a Moon-orbiting space station that will serve as a staging post for human expeditions to the lunar surface. Crewed and uncrewed landers that dock to Gateway will be able to transport crew, cargo, and scientific equipment to the surface.
Our astronauts will need a place to live and work on the lunar surface. Artemis Base Camp, our first-ever lunar science base, will include a habitat that can house multiple astronauts and a camper van-style vehicle to support long-distance missions across the Moon’s surface. Apollo astronauts could only stay on the lunar surface for a short while. But as the Artemis base camp evolves, the goal is to allow crew to stay at the lunar surface for up to two months at a time.
The Apollo Program gave humanity its first experience traveling to a foreign world. Now, America and the world are ready for the next era of space exploration. NASA plans to send the first woman and first person of color to the lunar surface and inspire the next generation of explorers.
Our next adventure starts when SLS and Orion roar off the launch pad with Artemis I. Together with commercial and international partners, NASA will establish a long-term presence on the Moon to prepare for missions to Mars. Everything we’ve learned, and everything we will discover, will prepare us to take the next giant leap: sending the first astronauts to Mars.
