Frequently asked questions

The kit includes 10 premium geodes, a pair of safety goggles, and display stands. It is designed to provide an educational and fun experience for children interested in geology and science.

The kit is recommended for kids aged 8 and above, due to the need for using a hammer or other tools to break open the geodes, as well as the presence of small parts and choking hazards.

Safety goggles should be worn to protect eyes. Place the geode inside a sock or cloth to prevent fragments from scattering and gently tap it with a hammer until it breaks open to reveal the crystals inside.

Kids can learn about geology, crystal formation, and earth science. They'll get hands-on experience with rock and mineral properties, and the excitement of discovery as they uncover the unique crystal formations within each geode.

    • Great product, if you also buy rock hammer, chisel, and second goggles
Style: 10 Geodes Kit
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. ... show more

The media could not be loaded. We recently purchased this geode kit to do with the family as a Christmas gift! and it exceeded all our expectations! The kit included everything needed for a fantastic rock-breaking adventure: 4 rocks to smash and/or chisel, clear instructions, protective glasses, and a magnifying glass to examine the treasures within. We were thrilled to discover 3 amazing geodes, each with beautiful, sparkling crystals inside. One of the 4 rocks turned out to be a solid piece of crystal, which, while smaller than the rest, was still a delightful surprise and not at all a deal breaker. We used the chisel method for two of them and had to use the towel and smash method for the hard to open ones. Our 8 y/o kid absolutely loved the experience! This kit provides an excellent hands-on learning opportunity, perfect for children and adults alike. Overall, a wonderful purchase that brought joy and excitement for family fun. Highly recommend for anyone interested in geology or just looking for a fun and educational activity. Will buy again for sure. ... show more

    • Geode fun
Style: 4 Geodes Kit
Such a fun activity. Great for my 9 year old. He loved doing it on his own and seeing what the Geodes looked like. I would buy more of these to do. Of course its messy but it's fun!

    • Fun!
Style: 10 Geodes Kit
My step-daughter and husband had so much fun opening these geodes together. It’s messy so you’ll want a containment plan. Some of the stones were very pretty and there was at least one semi-precious stone. The only drawback was the very last, biggest rock. Nobody could get it open until a ridiculous amount of force was applied. That stone wasn’t a geode, it was a solid rock. My step-daughter was really disappointed about that because we were sure that would be a really good one. The others were all good though so we would buy again ... show more

    • Kids had a blast!
Style: 5 Jumbo Geodes Kit
This was a gift for grandson, 9, and he had a blast smashing these open. It took several good whacks with a hammer, which was great, because they weren’t flimsy and didn’t just crack open right away; it prolonged the fun. Our granddaughter, 11, got in on the action, too, and she loved it. The crystals inside were great; mainly clear in color, but did have one or two with some blackish colored crystals. There were six or seven good sized geodes. This was lots of fun, and the best one of these type of activity kits we have tried. ... show more

    • The kids are hooked!
Style: 10 Geodes Kit
The lighter ones are the easiest to break. I was prepared to find that the description of the kit was a bit of hype. I was NOT. Prepared for how beautiful and instantly engaging these stones are. Purchased as a family activity- this kit exceeded my expectations. Getting the whole family to instantly fall in love with a branch of science is no small task and remarkable to find unfolding right before you as the kids with bored faces suddenly get round, astonished eyes as the first stone opens and all the glittering Chrystal s come to light for the first time since the world was created. Being the first humans to see inside a spectacular grotto of light and regular shapes - well, the kids were hooked! ... show more

    • Fun Activity, But Mixed Results
Style: 5 Jumbo Geodes Kit

Review Image by Aubry Aubry
The National Geographic Break Open 5 Jumbo Geodes was a fun and exciting activity, especially for kids who love science and exploration. Breaking them open was a blast, and the geodes that turned out well were really beautiful with fascinating crystal formations inside. However, not all of the geodes were impressive. A couple were mostly solid crystal structure with little to no inner cavity, which was disappointing considering the price and made all but one of them useless as display pieces. Despite that the images for this item displayed multiple colors of geode we received only plain white ones, I have no way of knowing if that is simply luck or what you should expect. Also, some were harder to break open than expected, the solid ones in particular gave our 10 year old extended periods of smacking them with a hammer to open. Overall, it's a fun, educational activity, but the results can be hit or miss. Great for curious kids, but don't expect all five geodes to be showstoppers. Out of all five, we got one good geode that we displayed. ... show more

    • Good Quality!
Style: 10 Geodes Kit
Bought these geodes to break in a class of high schoolers I teach. High schoolers are hard to engage, let alone, impress. They were not disappointed. Crystals were found in every geode! Kids had a blast and took theirs home. I would buy again!
