Rock Breaker Geology Crew

We each of our sons and nephews one of these kits for Christmas, in memory of a trip we took together earlier in the year to Carlsbad Caverns. They were all so excited, They ran outside right away and cracked them open. Some geodes took more time to crack than others. None longer than 15 minutes. Some, boys were more precise and careful about their hammer whacking than others, and they naturally took longer too. Out of a total of 8 geodes, (4 boxes) They all have interesting and unique results after cracking. I really appreciated that the kits came with an informative booklet, goggles, and a display stand for the "coolest" cracked geode. The boys were all impressed with their personal geodes.

Birthday gift for my 10 yr. old grandson. He loved it. Needed some help from dad to break the bigger one open but tons of fun. Every rock had beautiful crystals. He was delighted. I always buy my grandkids gifts that they would never expect. Not electronics! What kid or adult for that matter doesn't like breaking plain old rocks to find something so special inside. Thanks National Geographic you were a hit.

We bought this for our boys who are 4 1/2. They loved the goggles and the magnifying glass that came with the kit. Breaking open the rock was a little more difficult than I thought. My boys definitely couldn't do it. You will also need to make sure you have a hammer and chisel to break them open. The rocks we got looked very different which is great! One was black on the outside and one was a creamy white brown color and the insides were very different as well. The lighter colored one was also much easier to open. The rocks are so much prettier in person and they really sparkle in the sun. It comes with a nice picture book as well. Great activity! Definitely recommend!
