Math, science, and art collide in this glowing, expanding sphere. Using the same fascinating mechanics as all of Hoberman's transforming globes, this 9.5" Expanding Universe has glow-in-the-dark hubs that "explode" like shooting stars when the sphere is pulled out to its full 30" diameter. The purple links that make this magical motion possible drop out of sight when the lights are off. Play catch in the dark, use it as a night sky room decoration, or hang it as a mobile (hardware provided). With the included pulley and instructions, you'll have hours of expanding fun.Details:Glow10.1" x 10.1" x 9.6" package sizeContents include: 1 expanding sphere, pulley and instructionsFor 1 playerMade in ChinaBrand new condition in original packagingWipe clean with dry or damp clothFor ages 4 and up
