Made of linked plastic struts each one is a marvel of mechanical engineering. Pull on any of the spheres hubs and watch as it expands dramatically from 9. 5 to 30! Kids want to touch it, adults want to examine it, and everyone wants to play with it. All spheres come with a pulley, hardware and instructions to hang as a cool, kinetic mobile.
