The Pitch Drips…
I was very taken with the piece on the BBC Radio 4 Today programme earlier this week about the pitch drop experiment that has been underway in Australia since 1927. Pitch at room temperature appears to be solid matter; you can even smash with a hammer should you have both to hand.
In fact, given enough time, pitch shows the properties of a fluid and will eventually form a drip. As I write, the blog (and the world) waits for the ninth drop, since 1927, to drip.
For the live drip cam click through to the University of Queensland website here. For what it all means, ask Einstein. Oh, he’s dead you say? Well, given enough time, perhaps anything is possible.
In the meantime, here’s a time lapse video, taken over the last year, as the pitch gets ready to drip and… drop!
