A customer contacted our team with questions, and then finished their email with: "I am daunted by the complexities and unknowns." I haven't been able to stop thinking about it since.

The world's longest-running lab experiment

The Pitch Drop Experiment

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.

In the 86 years that the pitch has been dripping, various glitches have prevented anyone from seeing a drop fall.

I feel like now would be a good time to remind everyone that it is fully legal in America for the cops to lie to you and gaslight you in interrogation.

If they’ve decided you’re guilty and your lawyer hasn’t gotten there yet, they can and will say anything to make you confess and it won’t matter to them if the confession is true. Keep that in mind with any information that comes out in the next couple days. I’m not saying I don’t believe this is the guy. He very well could be. For now I’m neutral on the subject.

But I am saying it’s awfully convenient they found him with a butt load of evidence just on his person after a week of him evading them like a pro. And that the NYPD knows everyone thinks they’re chumps and they’re probably real desperate right now to look even halfway competent.

hey transfems, i don't know which of you need to hear this but it's okay to never use your penis during sex if you don't want to. it's okay to tell your partner not to touch it, to ignore it even, and hold them to respecting that boundary, no matter how many times you've had sex with them, or even if you've had sex with them with your penis involved.

you're not weird or broken for having needs or having boundaries, and you deserve lovers who respect those needs and boundaries. as someone who knows first hand, it's not worth it not to speak up.

this is a post for bottoms, switches, and tops. for subs or dom/mes. for anyone who feels like their no will go unheard or that the only reason people are sexually interested in you are those who want a woman with a dick. i promise you there are people who are out there who will listen, who will get you, and who will treat you how you deserve.

in fact? that's the absolute base line that anyone deserves during sex, and you deserve that and so much more.

Phenomenal!

everyone should be noticing how the media narrative has already moved away from the conversation of real hurt and pain millions of americans have experienced at the hands of evil health insurance corporations and is now instead focusing on his political beliefs and social media accounts. They will latch on to whatever distraction they can get to distract from the violence of the system that is dished out daily to PEOPLE LIKE YOU.

hey everyone be careful

I don't know if anyone has talked about this, but lately this has been happening in other fandoms too. There'll be these bot accounts that straight up steals people's posts and adds "expand" "read more" "continue" as a link in the end of the post - DON'T CLICK ON THAT, it's most likely a malware or something of the like.

so if you see a post like this: no profile picture, something that looks reposted (I've seen this happening to artists too) and a link at the end, even if the post has tags, that's a bot. Block and report it.

stay safe, and I hope @staff finds a way to stop these bots soon!
