Huge hits with the kids and adults. We had to revert to a sledge hammer to crack them open though. The geodes were impressive and are proudly displayed in our son's bedroom.

The National Geographic Break Open 5 Jumbo Geodes was a fun and exciting activity, especially for kids who love science and exploration. Breaking them open was a blast, and the geodes that turned out well were really beautiful with fascinating crystal formations inside. However, not all of the geodes were impressive. A couple were mostly solid crystal structure with little to no inner cavity, which was disappointing considering the price and made all but one of them useless as display pieces. Despite that the images for this item displayed multiple colors of geode we received only plain white ones, I have no way of knowing if that is simply luck or what you should expect. Also, some were harder to break open than expected, the solid ones in particular gave our 10 year old extended periods of smacking them with a hammer to open. Overall, it's a fun, educational activity, but the results can be hit or miss. Great for curious kids, but don't expect all five geodes to be showstoppers. Out of all five, we got one good geode that we displayed.

My step-daughter and husband had so much fun opening these geodes together. It’s messy so you’ll want a containment plan. Some of the stones were very pretty and there was at least one semi-precious stone. The only drawback was the very last, biggest rock. Nobody could get it open until a ridiculous amount of force was applied. That stone wasn’t a geode, it was a solid rock. My step-daughter was really disappointed about that because we were sure that would be a really good one. The others were all good though so we would buy again

We have had these multiple times so fun to break however I suggest cutting them or a sledge hammer for the big ones and they are beautiful

Great fun cutting to see the crystals inside. There were several different types and colors. Even found a pink amethyst geode in the mix!

This was a gift for grandson, 9, and he had a blast smashing these open. It took several good whacks with a hammer, which was great, because they weren’t flimsy and didn’t just crack open right away; it prolonged the fun.Our granddaughter, 11, got in on the action, too, and she loved it.The crystals inside were great; mainly clear in color, but did have one or two with some blackish colored crystals.There were six or seven good sized geodes.This was lots of fun, and the best one of these type of activity kits we have tried.

Perfect for our grandson with an adult helper., aside from needing a NOT INCLUDED rock hammer and chisel. Smashing with a regular hammer may be fun and satisfying, but it is not educational. Splitting the geode is educationalThe instructions and 10 geodes were wonderful. We've opened two so far, one a regular geode, and one basically a rock. Our six year old grandson helped us score the outside, when he got bored and left, I could carefully split both: the geode basically down the middle with a displayable piece and lots of fragments; the rock, I split off a hunk that showed the crystals that were the rockBe sure to also order rock hammer and chisel, which increased educational possibilities. The one I bought came with goggles, so we could both protect our eyes.
This is a Curley suit, I love it!

The lighter ones are the easiest to break. I was prepared to find that the description of the kit was a bit of hype. I was NOT. Prepared for how beautiful and instantly engaging these stones are. Purchased as a family activity- this kit exceeded my expectations. Getting the whole family to instantly fall in love with a branch of science is no small task and remarkable to find unfolding right before you as the kids with bored faces suddenly get round, astonished eyes as the first stone opens and all the glittering Chrystal s come to light for the first time since the world was created. Being the first humans to see inside a spectacular grotto of light and regular shapes - well, the kids were hooked!

Muy divertido. Ojo para abrirlo es necesario que ayude un adulto, pues las geodas hay que romperlas con martillo. Si lo haces con cuidado te quedan bonitas. Solo falta pulir las orillas.
