NATIONAL GEOGRAPHIC - Break Open 15 Premium Geodes – Includes Goggles, Detailed Learning Guide & 3 Display Stands - Great Stem Science Gift for Mineralogy & Geology Enthusiasts of Any Age

Trying to find alternatives to video games? Think your kids will benefit from hitting things with a hammer? Then this gives you an afternoons worth of focus! Because there are 15 geodes and some are pretty tough, it gave the kids an activity for a good couple of hours. Each geode produces at least 3 sections, the larger ones many more. Some are a bit duff some are really beautiful. That’s part of the fun. Quite expensive, but good fun and a nice ornamental display

All specimens in our collection were VERY similar. Not a lot of variety with internal crystal size or colour, which was disappointing. Instructions on opening geodes was basic and we had better results by watching various YouTube videos before opening our second specimen. Still, a good experience enjoyed by the whole family...

The media could not be loaded. Be prepared to use your muscles. We purchased a large chisel with hand guard and used a small but weighty metal mallet. We positioned the rock in a towel nest on concrete in the garden, away from windows, and whacked away. These were purchased for a 8 year old who had great fun fitting them but just couldn't break some. All very exciting and all round a great gift. Everyone joined in and there were lots of oooooos and aaaaaahs.

Awesome geodes. Look amazing when cut, I would say don't smash them. Look way better cut or opened with a hammer and chisel. If you sand the outside a little makes it easier to break open into two halfs. Awesome value for money. Really enjoyed opening them. Some were thunder eggs more than Geodes, solid inside which I loved but some may not enjoy if they want it hollow with crystals. I think thunder eggs are way more beautiful when sanded so all good. Only 4 out of the 15. I got a good variety but not a fan of quartz geodes as I have lots. But the ones in the pack had larger clearly crystals which I loved. I break them up and make jewellery and keyrings off of them so amazing for me I sanded down one that broke into bits and it's turned purple. Which is awesome. Defo recommend If you like minerals, gems and rocks. 😁

I was really looking forward to seeing what types of crystals i would get out of these but i was really disappointed when 3 rocks didn't have any crystals in and were just solid rock (i kept cracking them to see if there was a vain or anything but nothing). Also, we only got 2 type of crystals (clear quarts and calcite). Don't get me wrong they are all stunning in their own way but I was hoping for at least one other type so that everything wasn't just clear. Some of the stones were really hard to break so I wouldn't recommend kids to d this on their own.

No coloured, hard to break open as all are solid and the fact i can get plan rocks is crazy, they arent even quality controlled.

It was a christmas present. My son h was delighted. Very cool idea.

Like many reviews very disappointing for the money as all rocks are identical. Better ones elsewhere for same money
