Although some beads didn't 'puff' up all the way, they looked like raisins. **Q: How many water beads does it come with? ?** A: A lot. Do not put all the bag into the water at the same time! I added the entire bag because the bag did not look that large and the beads were super small! We ended up having to put them in the bathtub. I would suggest using no more than1/5 of the bag started. The more water you add, the bigger the beads get. Save the remained for replacement when the beads need to replace. I will buy this set of toys again for other kids. My kids like it. ## Frequently Bought Together - Solar System Planets Toys for Kids, STEM Educational Sensory Toys for Autistic Children Non-Toxic, Space Astronaut Slime Ball Alien Monster Toy Set with Mesh Storing Bag for 3-5-8-10 Boy Girls - Great Explorations, 3D Glow in the Dark Planets in a Tube, Ages 5 and Up - My First Book of Planets: All About the Solar System for Kids --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/355369892-coolduck-solar-system-planets-space-balls-stem-toy-educational-kids](https://www.desertcart.ro/products/355369892-coolduck-solar-system-planets-space-balls-stem-toy-educational-kids) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-06*
