Geode Smashing | Camp Classic Play!

Geodes are a rather entertaining little rock. The outside looks like a plain old rock, nothing special. But crack one open and its secret is revealed—inside it’s full of glimmering crystals that shimmer in the sun.
Want to give it a try? You’ll need a bunch of geodes (we picked ours up at a local toy shop but you can find them online), a hammer and a sack or sock. Place a geode in the sack, deliver a good thwack and see what you get.
If thwacking it isn’t enough, or you have a future geologist on your hands, encourage your kids to draw pictures of the geodes and research how they’re formed. For us, it was more of an exercise in fun and metaphor—you can’t always tell what’s on the inside by looking at the outside.
