      The Pitch Drop Experiment, to demonstrate that pitch is really a liquid which flows, is closing in on 100 years: https://en.wikipedia.org/wiki/Pitch_drop_experiment … (I used to walk past this every day - my office was in the same building!)

      I am lacking the right keyword, but I went to a great talk once where someone talked about an _air archive_. Basically, they went outside every day, starting in the 1960s, and bottled up some air, for decades(!) Then, after the fact, people can say "Oh, I want to analyze...

      Curious: are there examples of goals / projects that are easy, almost trivial to do over a very long period, say 100 years (or 1,000 years), but impossible over 10 years? Eg a scientific question that's trivial to answer over the longer time frame, but imposs over the shorter?
