NATIONAL GEOGRAPHIC Break Open 4 Geodes Science Kit Age 8+ – Includes Goggles, Learning Guide, Display Stand, Great Mineralogy & Geology STEM Gift

From reviews could see seemed hit and miss if get geos but thought would take the risk and got the 4 pack. 2 larger sized 2 smaller. Only one was a 'dud', it was a small one it and had some crystals on outside thought maybe more inside but was not case and just knocked them off. no complaints though as was expecting maybe one decent from them all. Was a bit tough opening, learnt best way for us was placed in zip bag and bashed. Overall me and boy was very happy and impressed with what we got.

It has been really fun opening these geodes - they all have beautiful sparkly crystals in them. Never mind that they aren't coloured ones, the whole family found them magical.

A fun kit that I did with my son & partner. The geodes were a reasonable size. I recommend wrapping in a old cloth, towel or something like that before using hammer to smash to avoid debris flying all over, also on a hard surface. We used kitchen floor as didn't want to damage our table. Don't go Hammer crazy either, I smashed the first geode to smitherines lol as got over zealous with jammer a couple of firm whacks and can check in-between to see how it's coming along. The book has some nice pictures & information. Each geode was different on the inside. My only complaint is i do find the kit quite pricey. It's a great kit but generally I think it could if been £2-£5 cheaper to make it more accessible & affordable price for those on lower incomes & budgets.

Very good value and great present for all ages

9 year old son was really excited to break open the geodes, he loved the safety goggles! They were quite hard to crack open. The disappointment was that they were all the same colour inside and that colour was a plain whitey cream colour, I think he was hoping for some other colours. Also one of the geodes didn’t have any crystal inside it was just solid.

These are great. My 6 y/o boy was really pleased, he's obsessed with stones and rocks. I wasn't sure how good they'd be, but we got 3 good rocks out of 4. Looking at the guide that comes with it we got 3 different types too.We used a chissel and hammer as suggested and that seemed to work fine. The more hollow ones crack open really easily, only light taps needed, one of the smaller more solid rocks took a bit off beating, so I did that one.A great set and worth the money.

In 2018, I bought the NATIONAL GEOGRAPHIC Break Open 4 Geodes Science Kit for my brother, who had a fascination with shiny crystals. While he was initially thrilled by the promise of discovering the treasures hidden within the geodes, his excitement quickly faded after just a few minutes of exploration. Despite the geodes revealing shimmering crystals, which resembled amethyst to some extent, the kit failed to sustain his interest for long. Alongside the geodes, the kit included a small magnifying glass, safety goggles, and a basic learning guide.Overall, I'd rate the experience a modest 2 stars. While it may serve as a suitable introduction to geology for beginners, particularly those with a curiosity about geodes, its allure proved fleeting. For enthusiasts seeking more depth and engagement, this kit may fall short of expectations.

Bought this for my friend’s son who is a young rock lovers. He loves it! Yet, it actually very hard to break and require support from adult to open it. Buy it if you know his / her parents won’t mind to help the little explorer. It’s a good experience. I think this box sets is in good portions. I know there is another box set that has more stones but charge just a little bit more. Very tempting, isn’t it? But after reading the reviews, the version with more stones brings higher expectations. So when the little explorer finds all the stones are actually similar, they become disappointed. And the helpers get disappointed as well (according to my friend, it requires quite some efforts to open each stone). So 4pcs version is a good experience. 10 pcs will be too much.
