Things like earbud cords have a nasty way of getting hooked on things and breaking. Such incidences may become a lot less common, however, as scientists from North Carolina State University have created conductive wires that stay intact even when stretched up to eight times their regular length.

The researchers made the wires by filling a tube of extremely elastic polymer with a liquid metal alloy of gallium and indium. As a result, even when the polymer is stretched to several times its relaxed state, the liquid metal inside of it is still able to carry an electrical current.
