-
Is it hard to crack open?
The geode takes a little effort to crack open. It has a treasure inside of it and isn’t going to give it up that easily! -
How large is it?
Every rock is a little different but they all have an outside diameter anywhere between 1 to 2 inches (2.5 to 5 cm).

a bit disappointed
Lisa Frank - November 1, 2010
I saw this item on line after looking at so many of the incredible products from Steve Spangler Science. I ordered 8 geode kits and was very excited to use them with a group of girls to demonstrate inner beauty. Of the 6 we cracked open, at least a couple were disappointingly drab on the inside, one looking like pure gray rock. I admit that my expectations were quite high, but had hoped for more from these. |

Some of them were pretty neat!

We got these as party favors for our sons 13th birthday at the Discovery Center. The kids were super excited to crack them open, but unfortunately, some of them didn't have any crystals inside, which upset a couple of the children quite a bit. The other kids, who did get crystals, shared their crystals with the ones who didn't, so all ended well. |

Fun in a Bag
Chris Bartal Utica, OH - October 7, 2009
We crack open geodes with our volcano unit, and the kids love them. Every child thinks he or she has found the most valuable treasure and fantasizes about the geode's potential value. You can have several kids share a geode if cost is a factor. |
