In 1911 a thread of frozen mercury did something no theory allowed. The needle collapsed, the lab assumed a short circuit, and it took another forty-six years to explain what had actually happened.

Start a current circulating in a ring of superconductor, then unplug the power supply. In ordinary metal the current dies in microseconds. In this ring it keeps going. Experimenters have watched such currents for years looking for any hint of decay and found none. The tightest measurements put the lower bound on the decay time past a hundred thousand years.
