The Hoberman sphere starts as a vibrant, 5.5" ball of strange, angular hinges. But then, pull it from the sides and suddenly it expands astonishingly into a 12” sphere! Tap or roll, and it magically closes again. Throw, bounce, spin, roll or even suspend it from the ceiling as a beautiful piece of art. Use it as a tool for teaching geometry and engineering concepts. Keep it on your desk for inspiration.
