Math, science, and art collide in this glowing, expanding sphere from Hoberman. Using the same fascinating mechanics as all of Hoberman's transforming globes, this 9.5-inch Expanding Universe has glow-in-the-dark hubs that "explode" like shooting stars when the sphere is pulled out to its full 30-inch 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. Includes 1 expanding sphere, pulley, and instructions Recommended for ages 4+ WARNING: CHOKING HAZARD: Small Parts Not for Children under 3 years Made in China Imported Material & Care Plastic Spot clean only
