    • Fun for my Science class

My kids loved breaking open their own geodes! The crystals inside were large and very sparkly, as my students said. They said science was fun today! Two of the rocks were very easy to break but one was more solid.

    • These ROCK!
These ROCK (pun intended). These are just fun. This is a project to do with your little humans. They don't know the value of a diamond, ruby, etc - they see shiny and that is the "price". These are fun with whatever you get inside. I'm sure they're hit or miss (no pun intended) but that is to be expected. No idea what they're selling or what you're buying until they're broken open. ... show more

    • Fun activity
My grandson loved breaking these and seeing the beauty inside. The reason I gave it a 4 rating is because all 3 geodes were too easy to break. I think he would have enjoyed working a little harder to break at least one. All in all, I’m satisfied with the purchase.

    • Family Fun with the Geodes Science Kit!
Our family had an absolute blast with the Discovery Break Your Own Geodes Science Kit. We spent a sunny Saturday afternoon in the backyard, eager to uncover the hidden treasures inside these 'science stones'. The kit comes with three large premium geodes. My kids (and, okay, I'll admit, the adults too) were full of anticipation as we each took turns with the hammer, gently cracking our geodes. When they finally broke open to reveal the sparkly, crystal-filled interiors, the looks on the kids' faces were priceless! This wasn't just fun, it was educational too. The kids got hands-on experience learning about geology, and the detailed information included in the kit sparked their curiosity about the natural world. My youngest even declared that she wants to be a 'rock scientist' when she grows up. Cleanup was a breeze - just a quick sweep of the fragments, and we were done. The kids have proudly displayed their broken geodes on their bedroom shelves, a lovely reminder of our fun and educational afternoon together. I recommend the Discovery Break Your Own Geodes Science Kit. It provides fun, engaging, and educational family time, and for us, it was a 5-star experience all around! ... show more

    • Not concealed
Cool rock set. However was delivered with the box exposed and address label right on the box which now makes it difficult to give as a gift. Also the package was seen by the intended present receiver. So that ruined the surprise.

What 5-year-old doesn't like banging on things with a hammer? And then to find a sparkly surprise inside was the icing on the cake!

    • Pretty cool
The kids loved these but be careful not to hit too hard. My oldest son swung too hard and pieces went everywhere. It doesn’t take much to break open so if you want a clean break then go easy on the hammer.
