The 24 Days of Science Advent Calendar by NATIONAL GEOGRAPHIC is perfect for curious kids who love to explore and discover. Behind each door, they’ll find either a hands-on science experiment to try or a real gemstone specimen to add to their growing collection. It’s a brilliant mix of learning and fun that makes the countdown extra special.
Inside are 13 exciting experiments—from revealing secret messages and making a test tube glow to floating coins and growing a colorful crystal tree. Alongside the experiments, kids will uncover 11 dazzling gemstones like carnelian, chevron amethyst, snowflake obsidian, geode, and tiger’s eye, complete with a storage pouch to keep them safe. And to top it all off, the final day reveals something extra special!
