## 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.

### ⭐⭐⭐⭐⭐ Un set diverso dal solito
*by M***T on 10 May 2021*

Questo set della Learning Resources è veramente ben ideato. In pratica sono 8 “pietre” tonde con all’interno ciascuna una pietra preziosa da aprire con martello e scalpello. Devo dire che è veramente originale e diverso dal solito, tanto che mia figlia ci gioca tantissimo. Io nascondo per la casa le pietre e lei fa finta di essere un archeologa e le va a cercare. Una volta trovate si diverte un sacco ad aprile una per una per scoprire quali pietra preziose sono racchiuse all’interno. Insieme nel set è compresa anche una comoda borsetta di tela in modo da poter riporre all’interno tutti i pezzi del set e non perdere niente. Nel complesso lo trovo ben realizzato ed il prezzo attuale, di circa 28 euro, mi sembra ber rapportato alla qualità stessa del set. Io personalmente lo consiglio, soprattutto per la sua originalità.
