Can you imagine the excitement after 8 years or so when the first drip dropped?

More details on Lord Kelvin's pitch experiment in Glasgow:
See figure 5.
Looks like Kelvin thought of it first (1887) and his version has been running longer.
There is a much older version of this 'experiment' started by William Thomson/Lord Kelvin in the late 19th century. A block of pitch was placed on the top of a wooden staircase and the pitch slowly flowed down the steps like a glacier. The apparatus was in the Department of Natural Philosophy (now Dept. of Physics)in Glasgow University when I left in 1960. Scott Hamilton.
