Abstract
A flexible tubular jumping rope or section of a jumping hoop is shown partly filled with a fluid and particles which reflect or refract light floating in the fluid. The fluid in combination with the transparent tubing forms an attractive and novel jumping device. A rigid center section is also provided of a light transmitting plastic which contains a fluid and light refracting or reflecting particles. The center section creates an attractive appearance and adds interest to the device. Different embodiments of bearings or rotary connections between end caps or handles and the flexible loop center section or jump rope are also disclosed. A sleeve surrounding a rigid center section, which permits rotation between the sleeve and the center rigid section is shown. The sleeve is gripped by the user's hand and the center rod rotates within the sleeve as the jumping hoop rotates around the user.
