Electric charge travelling through conductors encounters resistance and voltage has to be applied in order to maintain a flow of current. However there are materials, called superconductors, whose resistance drops to zero when cooled below a critical temperature. In superconductors, electricity can flow indefinitely without the need for a power source.
Last year a group of Japanese scientists at the National Institute for Materials Science made an incredible discovery at their own little party, they could induce superconductivity to a piece of iron telluride by first soaking it in a liquid. Most liquids worked, but alcoholic beverages, like whiskey, beer and sake worked better, and red wine worked best.
