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

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

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!

Perfect for our grandson with an adult helper., aside from needing a NOT INCLUDED rock hammer and chisel. Smashing with a regular hammer may be fun and satisfying, but it is not educational. Splitting the geode is educational The instructions and 10 geodes were wonderful. We've opened two so far, one a regular geode, and one basically a rock. Our six year old grandson helped us score the outside, when he got bored and left, I could carefully split both: the geode basically down the middle with a displayable piece and lots of fragments; the rock, I split off a hunk that showed the crystals that were the rock Be sure to also order rock hammer and chisel, which increased educational possibilities. The one I bought came with goggles, so we could both protect our eyes.

I really want to rate this higher but only half of them opened. I tried using a hammer and chisel. I tried hitting them with the hammer directly. I tried the sock method where I smashed them using every last ounce of strength I had. Nothing. Of the ones that did open, they were mostly simple sugar geodes. Pretty, but basic. For a kid, that will still be exciting, and honestly, even as an adult I enjoyed them, despite being in so many shattered pieces. I'm only knocking off one star though because, to be fair, NatGeo can't predict how easily the geodes will open, and otherwise it was a good kit for the price I paid.

I bought this for my 9 year old son who likes rocks. He had a blast busting these geodes open on the front porch area and was marveled with the colors. It was a very good gift.

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.

We were excited to try the National Geographic Break Open Geodes set because it sounded like a great hands on science activity. The idea is fantastic and it definitely creates excitement for kids. What we liked: It comes with 10 geodes, goggles for safety, and display stands, which is a nice complete package. Breaking them open feels like a real discovery moment, and it is a good way to introduce kids to geology in a fun way. What could be better: The results really vary. Some geodes were interesting inside, but a few were smaller than expected or did not have very impressive crystals. It also requires adult supervision and the right tools to break them safely, which is something to keep in mind. For the price, I expected a little more consistency in quality. It is still a fun activity, but not every geode will be a wow moment. Overall, I would give it 3 out of 5 stars. Great concept and educational value, but the experience depends heavily on what you get inside each geode.

We did some of these for our “Easter eggs” and they were a hit for all of our kids. Great deal and great for kids learning about rocks. My son was excited about the variety we opened.

Padrisimoooo mi hijo se divirtió muchísimo abriendolas!

This was super fun! They're great quality and the kids loved it bit did require some help!!

A mio figlio di 10 anni appassionato di minerali e gemme, sono piaciuti tantissimo! Abbiamo solo fatto un po di fatica ad aprirli perché molto duri ma quando poi abbiamo comprato uno scalpello ( all’inizio ci abbiamo provato con un cacciavite) finalmente ha funzionato.

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

We've gotten two of these kits, one several months ago for my daughter's 7th birthday (first image, with the organizer), and one for Christmas for her older sister (second image, by request after seeing her sister's birthday geodes). Both times we were very happy with what we had gotten, and I love the educational value, not just the geodes inside. The kids were fascinated and really enjoyed seeing what was inside. It's kinda like those kinder eggs/surprise toys, but naturally created! I have since bought a 3rd set when it was on sale (not opened yet). Yes, for the most part they are all white, however the first kit did contain crystal that was very pale purple (possibly amethyst?), and the second kit contained a milky pink mineral with a small crystally agate section. The first kit we had were mostly around 2 inches, the second kit had a wider range, of a couple really small 1 inch ones but a couple in the 3-4 inch range. Both kits we had resulted in a variety of hollow and full geodes, and varying size of crystal points, some small very glittery looking ones, and larger clearer ones. The second kit we had did contain a kind-of-dud, where there were tiny crystals, but mostly rock, but that was only one out of now 20 geodes we've opened from NatGeo. We have tried a different brand of break-your-own-geodes in the past, and they resulted in very few crystals (only around 20 to 30% had crystals), so I was very pleasantly surprised at what we got with the NatGeo kits. I might try to sand/polish a couple at some point. They were difficult to open, and did require adult assistance. I used a dremel to score the perimeter and provide a groove for the chisel to sit in (my dremel/dremel bits weren't strong enough to get through the crystal, just the outer rock), and then we used a chisel and hammer to crack it open. My kids were able to hammer some of the smaller ones open (with assistance holding the rock and chisel). But some, especially the solid ones, were still very difficult to crack open. Those took more time, but I (a petite, but persistent, female adult) did manage to crack them open with the chisel and hammer. In terms of "giftability" it really depends on the recipient/recipient's family.... as long as there is a willing (and patient?) adult to do most of the work as kids won't be able to do this themselves, it's a wonderful gift! But if not, they might not enjoy this as much.
