What Are Superconductors?

Imagine a speeding train that hovers above its track, yet never leaves the track, no matter how it curves, even if it flips over so that the train is flying upside-down!

This marvel and others are possible because of superconductors — materials that conduct electricity perfectly, but only when extremely cold. Anyone who finds a room-temperature superconductor will change the world.
