An electrically blinking jump rope is comprised of; 1) a flexible tube of partially transparent material, 2) two handles, containing batteries for electric power source, connected to the flexible wrinkled tube at each end, 3) a power switch on one of the handles, 5) a blinking lightning circuit comprised of two electric wires, plurality of LEDs connected to the two electric wires, and a blinking connector. The flexible wrinkled tube connecting the handle and tube of the rope enables a steady power supply even at high-speed rotation and severe motion of the jump rope. Two blinking connector is endurable to long and repeated rotational motion of the jump rope.
