Two contributors, Adrian Harvey and wirelessduck report, on a long-running experiment that has taken 84 years for someone to observe:
The pitch drop experiment at the University of Queensland has finally been observed producing a drop. Widely considered the world's longest running experiment, it was started 83 years ago in 1927. It was designed to show that even some solid-seeming substances like pitch will flow like a liquid given sufficient time. The flow is about an order of magnitude slower than the continental drift of the ground it's on! The experiment has produced drops before, but only when no one was watching. The last drop in 2000 even had a WebCam set up to watch it but the power went out just when the drop fell.
The pitch has dropped - again. This time, the glimpse of a falling blob of tar, also called pitch, represents the first result for the world's longest-running experiment. Sadly however, the glimpse comes too late for a former custodian, who watched over the experiment for more than half a century and died a year ago. Up-and-running since 1930, the experiment is based at the University of Queensland in Australia and seeks to capture blobs of pitch as they drip down, agonisingly slowly, from their parent bulk.
[Editor's Note: The discrepancy in the dates between the two articles is as they were reported. Obviously, at least 1 is incorrect, but the TFS does not change source material]

From there, both dates are sort of correct. The pitch was added to a sealed stemmed funnel in 1927 and allowed to settle for three years before the stem was cut.

I would attempt to explain it, but the TFS does that quite nicely.
Technically, lunchtime is at any moment. It's just a wave function.

It's related to the Doppler shift.

Ok, it has been observed, photographed, counted, etc.
How much longer does this experiment run? At any proposal to terminate it, someone is bound to say, "BUT 84 years! We can't stop now!!!".
You want more drops, turn up the heat. But jeeze, it was silly in 1927 and hasn't improved with age.
No, you are mistaken. I've always had this sig.

Really. I even RTFA and I still don't get what the experiment is for. Hey, I got an idea, let's watch grass grow and make a big deal out of it, I'll make millions. If the idea is to figure out the viscosity of pitch, no offence to science, but is there not a better way?
A cool entertainment value sure, but science experiment? Need a little more.

My attitude is that the more we know about our world, the better. The viscosity of pitch may not seem that important superficially, but it adds to our understanding of the world. Perhaps this could help scientists in other fields date things or something.
It also doesn't seem like it's an especially expensive experiment to run. How much does it cost to keep a jar of pitch in a cupboard?

It has run for 84 years.
We already know a ton more about pitch today than when the experiment started. It's already yielded all the info it is capable of yielding, which never was all that much.
Hell, even concrete flows. Science has bypassed this issue and moved on.

Your implied suggestion is that every experiment be run forever in the hopes that doing the same thing over and over again might yield different results.

So it has become an experiment in digital data recording?
Odd, because nothing of the sort was even imagined when the experiment started, since no digital devices existed.

I said we're still learning. Learning how to properly capture the data is also something of value we are getting from this experiment. Since only one drop was captured as a video....
"Goalpost shifting is just another example of an unreasonable emotional attachment."
So... what, I'm a Pitch Drop fanboy? Riiight, nice rebuttal. Anywaaaaaaaaaay data collection is the key to achieving anything with science. There's value in capturing more drops, there's value in improving the reliability of the data capture. "But it's run for decades, I'm bored!" is not an actual reason to shut it down, though it has proved entertaining in light of your recent post.

I think it has transitioned from being an experiment into more of a historical, interactive museum exhibit. Seeing as the net cost of keeping it is basically zero, why stop? I don't think anyone is claiming that it's some scientific miracle, just that it's something of potential historical interest.
We don't go throwing dinosaur bones into the tip just because everybody has seen a dinosaur skeleton before. It's a part of scientific history, albeit perhaps a slightly trivial one. Why not preserve it?

The experiment actually does yield a tiny amount of useful data on the properties of pitch.
More importantly, it's a fun experiment that adds a bit to the popularity of and general interest in science. Given the low cost, this is very worthwhile.

OK, i went back and read all the articles. the counter-evidence posted is BOLLOCKS. totally one-sided and based on the views of a small group of "scientists". we're not talking about fossilized amber, that's a whole 'nother jar of worms, and on a timeframe of "well beyond the age of the universe" glass is likely to transmute into entirely different elements or at very least decompose. now from personal experience i've seen stainded glass windows in churches that have ran like candle wax and sagged onto the ledging well outside of the lead framing. I dunno why, maybe stained glass is softer, or maybe there was a fire at some point that superheated the windows, or maybe the nazis had a top secret anti-window faction that went around the globe with flame throwers and unsuccessfully tried to melt all the story-glass after they were done burning books, or may be it was due to blast jets from recent visitations by ancient aliens.. i dunno, but i'd buy any of those stories over my T-89 pocket calculator says NO. /endrant

The first recorded observation of a pitch drop was actually done in Trinity College Dublin [www.tcd.ie]. The experiment there was not as old, and long neglected. I also note that the drop occurred in the midst of a summer heat wave, but never mind.
