The box has 15 little geodes from 1 to 1.5 in. in diameter in a bag, the plastic safety glasses and a glossy, illustrated booklet that explains how geodes came into existence and their various types.
The actual fun is the breaking of geodes to reveal the crystals inside and this is where I am deducting half a star. While this is a very interesting activity, it's also something that children, especially children from ages 6-12 simply can't do on their own. The rocks were not easy to break and, as hard as she tried, our 9 yr. old armed with a hammer and a chisel could barely scratch the surface. Our 15 and 16 yr. olds found the rocks difficult to break as well - yes, anyone can smash rocks with a big hammer but the goal is to only crack them into 2 halves, 3 (thirds) at most.
Our first session lasted more than an hour and it consisted of reading the 8-page booklet and then the kids and myself worked on breaking the rocks open. Once a geode was successfully cracked we would spend some time trying to identify it using the booklet as our guide, then admire than crystal formations inside. We cracked 8 out of the 15 provided rocks, saving the rest for a second session. I don't know if it was luck but most of the geodes we opened were quite interesting, including a very nice Amethyst geode, some containing nice and clear Quartz crystals and some with smaller crystals but arranged in interesting formations.
This can be a fun and educational activity for as long as the geode-cracking part is left to the grownups.

The kit includes 15 unopened Geodes, a glossy manual, and safety goggles. The glossy instruction book is packed full of details on how geodes are formed and is very informative. The geodes range in size from about 1.5" to 2.5" in diameter and most can indeed be broken open by children in the target age range (6 and up). We place the geodes into a thick plastic freezer bag (see video) and we all enjoyed opening them with a hammer (not included), with "Whack it again!" as a common encouragement! The inclusion of plastic safety goggles was a nice touch and very responsible of the kit maker.
Out of 15 geodes, we were able to open 14 of them without much effort and the last one was able to be opened by me with a very heavy hammer. The crystals inside ranged from fairly small to impressively nice, but all of them were good looking and definitely worth having.
This is a great family activity that teaches important geological information and gives you a lasting, pretty reminder in the form of the opened geodes.
Note: Kit provided by manufacture for review, but that in no way influences my comments or rating
All that said, the 8 brittle geodes are still sparkly, kids are still full of wonder when they break open and these are easier for them to break themselves although it's almost impossible to keep them from shattering. Just know this kit is heavy on the clear, brittle geodes.

I am attaching a collage of two photos that I will be referring to in this review.
Photo #1 shows the entire content of the kit next to the ruler so you can see the relative size of the geodes. The kit includes 15 geodes and eye protection glasses. The kit requires you to use your own tools: a hammer and a chisel.
The guide gave us two methods for cracking the geodes: the chisel method and the sock method.
Method 1: Before cracking the geodes the instructions said to score the geodes so they would break along that line. We did not have a chisel and used a big screw and a screw driver to score the stone. Perhaps the lack of the proper chisel explains the difficulty in cracking the geodes. After scoring the geodes we tried tapping them with a screwdriver positioned on the scoring line. Kids could not open any, I was able to crack just a couple. Photo #2 shows the opened geode with white crystals on the inside.
Method 2: Putting a geode into a sock (to prevent small pieces flying around) and hitting it with a hammer. This method requires more strength than method #1. Three of us did not open any geodes using this method.
I wish the kit included a chisel as this is not a common tool like a hammer, and it might have made a difference for us.Read more ›

Grandson disappointed. This was expensive and the Geodes were super small and not great inside. Also, not many of them. Would not recommend.Published 1 month ago by liz
This is a great activity with kids. Most kids like "gearing up" with glasses and using adult tools. We used a regular hammer. Read morePublished 6 months ago by GMS 27
