This reminds me of pitch-drop experiments: https://en.wikipedia.org/wiki/Pitch_drop_experiment https://en.wikipedia.org/wiki/Pitch_drop_experiment Pitch flows _slowly_. Apparently it is so viscous that at room temperature a suspended blob might release a drop about once a decade or so. A few university physics departments have had experiments to watch pitch drop running for almost a century.
