## Description

Children can explore the mechanics of expansion and contraction while developing motor skills and creative thinking through interactive play. Whether used at home, in classrooms, in therapy settings, or as a unique office or bedroom display, the Rainbow Sphere delivers endless fascination and repeat play value. The lightweight yet durable construction makes it easy to expand, collapse, toss, and display. Its vibrant rainbow colors make it visually exciting for all ages, while the innovative design has made the Hoberman Sphere an internationally recognized classic for decades. Great for birthdays, holidays, classrooms, sensory play, and family game nights, The Original Hoberman Rainbow Sphere combines educational value, creativity, and unforgettable kinetic fun in one iconic toy. desertcart.com The Hoberman Sphere starts small and grows larger. And vice versa. Made of rainbow-colored plastic links, the sphere expands to 30 inches in diameter and contracts to a compact 9.5 inches. There's a hypnotic fascination in making the sphere expand and contract over and over again, but if kids want to do more with their sphere, a guide (included) lists some possibilities. How about trying the ballerina spin, the flip down, or the hot potato? The sphere can also be a fashion accessory. Think spiked hat or, even better, space helmet. Another option is to hang the sphere as a mobile. A pulley system is included, and a pull of the ring will cause the sphere to contract. Release the ring for expansion. Plenty of fun, the Hoberman Sphere might get kids thinking about mechanical engineering and some folding/unfolding projects of their own.

## Questions & Answers

**Q: My Hoberman sphere got locked in the open position.  Is it broken or is there a way to close it?  I can't find the instructions - hardcopy or online!**
A: Had the same problem; went through and checked that all the pieces were fully clipped and noticed some yellow ‘tabs’ that don’t clip-they sort of act as stops to keep it from opening too far. Some of the tabs were stuck when the sphere had been forced open too far. Fixed the tabs and it closed right down!

**Q: How do you contract it once it's locked open? Lost directions.**
A: Hold the sphere at top and bottom and let it collapse.  IF hanging it will stay open only.  This thing does not lock to the best of my knowledge

**Q: how tall is it in feet?**
A: 2 1/2 feet.

**Q: Is there a Hoberman sphere that expands larger than 3 feet?**
A: The Mega Sphere expands to 4.5 feet.
