Some of the most patient physicists ever have seen what no-one before has ever seen — A drop of pitch — a very sticky, viscous substance that flows very slowly — falling. Back in the 1940s, pitch was but in a glass funnel, melted, let to set, and then put in a cupboard in the Physics Department in Trinity College, Dublin. The pitch forms a drop about once every ten years, and on July 11, a webcam set up to watch the experiment 24/7 caught a drop falling. See the excitement here:
There’s another experiment in Queensland, Australia, has been running for even longer, but a glitch in their webcam meant that they missed the last drop falling. Dang!
