Super stretchy conductive cables

    Conductive cables able to stretch up to eight times their original length could make electrical outlets more accessible--and let you share your headphones with your friend seated three rows back.
    The idea is to develop the wire by filling a thin tube made of an extremely elastic polymer with a liquid metal alloy. Made of gallium and indium, the alloy is a good conductor of electricity, and keeping the materials separate rather than embedding the metals directly into the elastic material allowed for maximum conductivity without reducing elasticity.
