Superconductors make highly efficient electronics, but the ultralow temperatures and ultrahigh pressures make them costly and difficult to use. Room-temperature superconductors promise to change that.
Magnetic levitation is just one of the interesting attributes that make superconductors so interesting.

Superconductors are materials that can transmit electricity without any resistance. Researchers are getting closer to creating superconducting materials that can function in everyday life.
