Don’t Be Fooled By These Rocks That I’ve Got, I’m Still Just a Mom From the Block
Do you have kids? Do they like smashing stuff? Do they like bling-y shiny stuff that looks expensive? If so, I know what to get them! Sure, they can break these pretty geodes open with a hammer. Or, they can drop them off the deck in a pillowcase, try to make a basketball point with them or crack them open in a myriad of creative, destructive ways that only children under 10 can dream up. Make sure they have protective eyewear and say a small prayer, then stand aside while they have marvelous fun doing what kids love - breaking stuff! Enjoy their innocent wonder at the beautiful sparkling crystals inside. Don’t correct them- These ARE precious jewels if your kids say so. Let them use them as pretend currency or in fancy art projects. Mine wants to make jewelry out of them. They provide quite a lot of entertainment. They also spark creativity and optimism- if these look like ordinary rocks you’d find anywhere- then the world can be full of awesome unexpected magic! ... show more

Super fun for kids & adults
This is an amazing gift for kids and adults alike. I bought these for my wife as kind of a gag gift and we had so much fun with it, that we immediately bought another box. The geodes quality is very good. You'll probably get a dud or two, but that's all part of the fun. It's exciting to see what is in each one when you crack them open. Parents will certainly have to assist children, but when you're done you'll have amazing keepsakes. I can't recommend this enough. ... show more

Meh. Lots were just cool rocks
Luckily I had a dozen very proactive 8th graders on the job, and after about 1 1/2 hours we cracked a dozen geodes. Exactly one cracked as hoped. Some of the geodes had very thick layers of regular stone that had to be hacked through. Maaaaybe half were truly hollow, the others had layers of crystal but didn’t have open space with crystals. Bottom line, there were a few geodes as expected mixed in with cool rocks that were very difficult to crack open- and when they did they mostly cracked into small pieces instead of 2-3 nice chunks. I ultimately let the kids throw them against an old brick wall until the outer rock was breaking down and starting to crack, then use the hammer. That was the most effective method. The kids had fun, no teacher ever let them throw rocks at the wall before lol. It helped they didn’t see the box and had no expectations. ... show more
