## Questions & Answers

**Q: Is there a set that is a little more difficult. Would like to get for a 3 yr old but worried she master it too quickly and grow bored. ?**
A: My 3 year old granddaughter solved it quickly, but we still had fun putting them back together and repeating the cycle. I've put little notes in one and told her she's got mail somewhere in that bucket. She wasn't bored with it. It helps that mom has closet space to rotate the toys that are boring now and do the same in a few months. That helps too. Also, Discovery has a "Crack your own geode". I bought it on Amazon. You get 10 geodesic in the box.

**Q: What size is the “geode” when closed?  Looking for the diameter, please.**
A: The Geode size is 2". If you have any other questions, please visit us on our Learning Resources site under the "contact us" page and we'll be happy to help.

**Q: Can you open this without using the tools?**
A: My niece is two and she had to use tool's to open them. She loves them.

**Q: Would a six year old still enjoy this?**
A: My son got this for his 6th birthday and he loves it. My 9 year old daughter also loves playing with it. My kids like mixing the colors and hide them like Easter eggs through the house.

### ⭐⭐⭐⭐⭐ A Great Buy!!
*by S***A on 1 August 2025*

This toy is exceptional! I was very keen for it for my grand daughter and it did not disappoint. She was very excited and was able to play with it with ease. The "jewels" are lovely. My grad daughter played with it for 20 solid minutes and was looking to play with it each day during the toy rotation. A great buy!!
