KA-BOOOOM! The Universe began about 15 billion years ago with a tremendous explosion called the "Big Bang." We've captured a miniature Big Bang explosion in this package of stars. When you open it you can transform your ceiling or wall into a universe complete with glowing galaxies and dazzling constellations! These celestial products out-glow all others thanks to the Glomonite formula! The different sized stars are invisible on a white ceiling by day and glow brightly at night. Package contains 50 glow-in-the-dark stars and adhesive putty. Not for children under 3 years.
