Por que algunos no crece ?** A: Hay que colocarle todo el quimico despacio y si aveces hay partes que no crecen por alguna razòn. **Q: Can I put this in a glass dome or will that make it explode? I don't know if chemicals or process could cause build up of pressure in enclosed globe.** A: I believe you can put it in a glass dome it may help preserve the crystal longer. **Q: How long do the crystals last once they’re grown? Are they permanent or do they crumble after a bit?** A: they definitely crumble into a powder at the base of the paper trees they grew on they're not long lasting crystals like I had when I was a kid, but they are amazing to watch grow (and you CAN watch them grow, it's THAT fast). instant satisfaction for a younger child, vs the set and leave it for a month of the old time crystal growing kits. ## Customer Reviews ### ⭐⭐⭐⭐⭐ SUPER FUN FOR THE KIDS *by T***G on 4 May 2026* KIDS LOVED IT. ### ⭐⭐⭐⭐⭐ Kids liked it *by K***E on 1 June 2025* Great ### ⭐⭐⭐⭐⭐ 高かった *by 卵***き on 13 March 2025* 高かったです。 ## Frequently Bought Together - NATIONAL GEOGRAPHIC Craft Kits for Kids - Crystal Growing Kit - Grow a Crystal Garden in Just 6 Hours, Educational Craft Art Project, STEM Crafts for Girls Ages 8 9 10 11 & 12 (Amazon Exclusive) - NATIONAL GEOGRAPHIC Mega Crystal Growing Kit for Kids- Grow 6 Crystals with Light-Up Stand, Science Gifts for Kids 8-12, Crystal Making Experiment, Science Kit for Girls and Boys (Amazon Exclusive) - NATIONAL GEOGRAPHIC Gemstone Dig Kit – Dig Up 10 Real Gemstones and Crystals, Science Kit for Kids, Gem Digging Kit, Gift for Girls and Boys, Mining Kit, Rock Collection --- ## 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.tn/products/377079976-blue-marble-national-geographic-crystal-growing-garden-stem-kit-geode](https://www.desertcart.tn/products/377079976-blue-marble-national-geographic-crystal-growing-garden-stem-kit-geode) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-31*
