Tumbling geodes to uncover what’s underneath the surface 🪨 I bought these geodes to hammer open…and when I couldn’t crack them open, I decided to tumble them to see the fortress hidden inside! Geodes take millions of years to form - they’re hollow rocks where crystals live! They form when water seeps into cracks in the rock, and layers of minerals build up. I can’t wait to see what’s inside! You can purchase both the geodes and rock tumbler in my amazon shop - the link is in my insta bio💚 | Gr
