When made very cold, certain substances have almost no resistance to electricity; they become superconductors. This was first observed in 1911 using mercury. More than 25 other metals, including Copper and various alloys, behave in the same way. Superconducting coils that allow current to flow practically non-stop are used in particle accelerators. New materials that superconduct at room temperature are being developed.
