I can't get them out without the crystals literally crumbling.** A: It does not pop out easily... it's really hard and when you try the entire crystal shatters. Huge disappointment. **Q: Do I need to buy additional items for this, or are all supplies in the kit?** A: Hello,This kit does come with everything that you will need for this experiment (except the heated water to add to the crystals)! Thank you for your inquiry,MeganNational Geographic Toys Customer Support **Q: Is this good for a 12 year old?** A: I am not sure.. I would think so .. I got it for my 9 year old grandson for Christmas this year.

My tow sons helped make crystals and they absolutely fell in love with the experiment. You do get different results each time you make the different colored crystals. They do take about 4 days to completely form but it was worth the wait. ### ⭐⭐⭐⭐⭐ Whole Package Screams Quality *by A***R on December 27, 2017* The whole package screams quality. I am very eager to grow these with my niece and nephew. Pros: The whole package screams quality, the small touches like a "fill" line are really appreciated. The silicon growing containers allow for easy removal of the crystals, minimizing the chance that they will be damaged. The LED's in the night light is very bright, I'm very eager to see what the final results will look like with the crystals glowing on it. I didn't expect to see a glow in the dark mix, which is a very welcomed surprise. The light base is super cool; part of me wants to put the night light in my room instead of the kids' room like i originally planned. Cons: The premixed bags and limited supply of seed crystals don't lend itself to much experimentation. If any experimentation is to be done, it's best done with the 3 colors you probably don't want on the display stand. With only 4 growing chambers that will fit the display stand, it means that in order to get 5 crystals to fill the display stand you'll have to wait 7-10 days for the first batch of crystals to finish growing first then wait ANOTHER 7-10 days. This is less than ideal for kids (and adults) who tend to not be the patient type, and requires an extra amount of planning if the finished night light is supposed to be a present. Other notes: According to review photos, the glow in the dark mix is clear to white when grown, so I'm curious to see if i can mix it to create lighter variants of the other colors. ## Frequently Bought Together - NATIONAL GEOGRAPHIC Mega Crystal Growing Kit for Kids- Grow 8 Crystals with Light-Up Stand, Science Gifts for Kids 8-12, Crystal Making Experiment, Science Kit for Girls and Boys - NATIONAL GEOGRAPHIC Break Open 10 Premium Geodes – Includes Goggles and 2 Display Stands - Great STEM Science Kit, Geology Gift for Kids, Break Your Own Geodes with Crystals, Toys for Boys and Girls - National Geographic Craft Kits for Kids - Crystal Growing Kit, Grow 6 Crystal Trees in Just 6 Hours, Educational Craft Kit with Art Supplies, Geode Specimen, STEM Arts & Crafts Kit (Amazon Exclusive) --- ## 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.co.za/products/33955715-national-geographic-mega-crystal-growing-kit-with-8-crystals-ages](https://www.desertcart.co.za/products/33955715-national-geographic-mega-crystal-growing-kit-with-8-crystals-ages) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-10*
