National Geographic Break Open 10 Premium Geodes – Includes Goggles & 2 Display Stands - Great STEM Science Kit, Geology Gift for Kids, Break Your Own Geodes with Crystals

My nephew loved this! He is curious little man and this was perfect for him. Not too messy, had a great variety of geodes that looked amazing under the National Geographic microscope we got him. Definitely an outside/patio activity since he has a baby sister we try to keep the noise down for but overall 10/10.. In his words "these are amazing". The adults were even entertained!

The National Geographic Break Open 10 Premium Geodes kit is an absolute hit for kids who love science and exploration! I bought this as a gift, and it exceeded all expectations. The kit comes with 10 geodes, safety goggles, and 2 display stands, making it a complete hands-on geology experience. Opening each geode is thrilling — the surprise of discovering sparkling crystals inside never gets old! The geodes vary in size and crystal type, which keeps it exciting for kids as they break each one. The included instructions are clear and easy to follow, and the goggles are a thoughtful safety addition that makes the activity worry-free. This kit is educational, fun, and encourages curiosity about geology, STEM, and natural science. It’s perfect for home experiments, science parties, or a unique gift for young explorers. Durable, well-packaged, and endlessly engaging

Our son loved these. Super fun to crack open. Really pretty inside.

My 5 year old really enjoyed the experience of breaking these open and admiring them but I don’t think it was worth the money we spent. There wasn’t much variety and they all looked pretty similar. None were pink or purple as the pictures depicted. They were all just white/gray inside. They were a decent size, about the size of a golf ball. National Geographic always does a good job at being educational so like other kits, they included an educational pamphlet about geodes so that was nice. They aren’t too messy since we busted them outside and just brought the solid pieces in. The quality of this kit was ok but I wish there was more variety and color to the pieces. All of the pieces were included and overall my son is happy with it so I’m glad for that.

What a great gift for my grands. And the got to use a hammer.

Great gift for a 5 year old rock lover who says he’s going to be a geologist. Nice size Geodes are a little hard to open without the help of an adult. A little messy, but worth it!

The size of most of them were completely reasonable, not smaller than expected. Out of 10 however only 2 were hollow inside. Most were solid all the way through which made them very hard to break. Impossible for a younger child and challenging for an adult, and that is with a chisel. We had a much better experience with the 5 jumbo kit.

I’m pleased with the geodes we got in our box. I’ve had this 10-pack in my cart for a little while debating if I should pull the trigger or not after seeing some disappointed reviews. It seems a lot of people get either 10 boring clear quartz or a mix of 10 clear quartz geodes and nodules. I decided it’s only a $30 gamble so may as well. Ordered and it showed up 12 hours later. For 2 or 3 it took a while to bust through I’m assuming because two of them were nodules. The rest were relatively easy to break through with a heavy duty flat heat screw driver and a hammer. I also used a vise clamp to hold the geodes in place while I hammered away. Chipping little by little and rotating to try and split them in the middle worked fairly well. We received probably 50% clear quartz, however we also received the other half having some color. You could tell from the exterior if there was going to be some color inside, it’s pretty obvious once you crack a couple open to see the pattern. The pale beige, almost white, geodes are clear. The darker exteriors had some dark grays inside. One was darker exterior with a reddish hue and had some dark grays inside with some dark reddish flaking which was really nice. They’re not amazing, and I’m sure they’re overpriced for what they are, however I’m happy with what we received. I popped them in some floating display frames I got cheap on amazon and put them on a shelf that gets hit from the side with filtered natural light.

Padrisimoooo mi hijo se divirtió muchísimo abriendolas!

Great set but be warned, these are quite hard to open. With the regular hammer, I probably had to hit it for a good 20min! I guess it attests to their authenticity

Perfect for getting kids to do something

This geode kit comes with the “huge” rock itself, a zip bag with some dust😅, and a full-color booklet 📦. Fair warning: it’s covered in dirt, so open it over tiles or take it outside unless you want sand everywhere 🤪. Give it a quick rinse and brush before cracking—way easier than trying to clean the insides later. I used a power tool and got a clean split; inside was a big cavity of pure white crystals🤍. Checked other reviews and yep, pretty much everyone gets white ones, so don’t hold your breath for the purple or blue beauties in the booklet 🥲. Still, the moment it cracks open is pure magic for kids (and adults). The instructions are smart—wrap it in a sock or cloth first so shards don’t fly🥸. Not a treasure haul, but the hands-on “wow” factor is totally worth it. Kids will love it—recommended 👍.

Wurde als Geschenk für einen 9 jährigen gekauft. Nach kurzem Zweifeln des Kleinen (Was soll ich mit ein Haufen Steine??), kam aber dann schnell Begeisterung auf, nachdem wir zusammen dann mit Meisel und Hammer die Steine vorsichtig geteilt haben. Manche Steine sind innerhalb 2-3 Minuten offen und sind auch von Kinder leicht zu öffnen. Die anderen, wesentlich härteren, sind nur durch ziemlich viel Kraft zu öffnen. Aber es geht. Wie gesagt, alles mit Hammer und Meisel :-)
