Do you need to have a separate tool for that?** A: The best way to open them is to take a large file & carefully cut a groove around the Geode along any depressions in the shape. Place in on a towel on a concrete floor. Be sure to put on safety glasses! Take a large chisel and place it in the groove. Strike the end of the chisel with a hammer to break the Geode open. Be careful everyone standing near has their safety gasses on as well! **Q: Can use a sharp,big knife or if not, what do you use** A: Please do not even consider attempting this with a knife. That is an E.R. trip in the making. We were quite successful with a hammer and wide chisel. **Q: Does the item include a hammer?** A: If you don't already have a hammer, this item is not for you. **Q: Are they fake** A: They are real just not real impressive. You're better off to buy bigger geodes online. The kit has nothing spectacular you need. My package was full of solid rocks. Took a 5 lb sledge to get the apart. 100% waste of money. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Chonky sized Geodes, fill an adults hand, huge for kids. *by G***N on 23 February 2026* Got these for my youngest as he wanted something chonky, they are about the size of a snowball for an adults hand.

Two wouldn't open and we broke the paving slabs and brick underneath we were hitting them so hard. The ones we opened were all the same the ones we could split were just rock! ## Frequently Bought Together - NATIONAL GEOGRAPHIC Break Open 5 Jumbo Geodes - Earth Science Kit with 5 Premium, Extra-Large Geodes with Crystals, Goggles & Display Stands, Science Gifts, Fun Stuff for Kids (Amazon Exclusive) - INCLY 5 PCS Geology Rock Pick Equipment Kit, 32 oz.
