He even looks like a professor!
Just getting ready to perform the experiment took years. First the Professor heated a sample of pitch and poured it into a sealed funnel. Then, he waited. For three years Parnell let the pitch settle in the funnel, until in 1930, when he felt the pitch was settled enough, he cut the bottom of the funnel, freeing the pitch to begin its mind-bogglingly slow downward escape.
Listed as the longest running lab experiment by Guinness World Records, the pitch experiment not only outlived its creator, but will likely outlive us all. It has been estimated that there is enough pitch to keep it dripping, ever so slowly, for another hundred years.
