Watch This Stretchable Wire Heal Itself

Inventors: do this to gadget chargers immediately. One of the biggest problem with wires? They break. Enter these self-healing wires from North Carolina State University. The wires have a liquid-metal core and polymer sheath and can reconnect at the molecular level after being severed. Like NCSU's earlier wires, the liquid core makes them stretchable, which makes them perfect for use in dangerous environments. (Or any environment where you don't want something to break.) To make the wires, the r...
