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. Winner of the Parents' Choice Award. --Wendy Slotboom Product Description A rainbow of primary colors effortlessly changes volume up to 30 times! Colorful linking rings provide hours of fun!

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. https://www.amazon.com/dp/B00005N5FV?ref=myi_title_dp ## Customer Reviews ### ⭐⭐⭐⭐⭐ Lots of fun for all ages. *by J***D on January 30, 2026* Great for all ages. Good quality and durable. ### ⭐⭐⭐⭐⭐ What fun! *by N***R on September 30, 2025* What fun! When I took it out of the box, I was skeptical about being a good toy but when the grandchildren visited my mind was instantly changed. The 4 yr. old boy was just as delighted with this as was his 2 y/o brother. I wish I hadn't presented it to them together because sharing was impossible and not a back and forth catch game I naively anticipated. This is a durable toy that will offer hours of entertainment. ### ⭐⭐⭐⭐⭐ Interesting product that involves your imagination *by I***. on February 11, 2024* The product seems well made and is interesting for adults from an engineering perspective. For children it's use is up to the individual. I bought this for an autistic relative and the toy promoted interaction between us that had us giggling. How big, how little could it get, make your own sounds while expanding it, pretend to get your arm stuck in it... Use your imagination and I think this is a good toy to promote interaction. I don't know what the age recommendation is but would keep it to older children ## Frequently Bought Together - Original Hoberman Sphere Plastic Expandable Toy, Rainbow - Hoberman Expanding Mini Sphere Toy - Hoberman: Sphere-- Expanding Universe Glow --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/1321226-hoberman-original-sphere-rainbow-expanding-and-contracting-geometric-ball-toy](https://www.desertcart.sn/products/1321226-hoberman-original-sphere-rainbow-expanding-and-contracting-geometric-ball-toy) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-08*
