The Dazzling STEM Excavation kit allows kids to become miners in search of beautiful and sparkly gemstones. Provided is a mound of rocky earth that kids can begin chiseling through to unearth eight wonderful crystals. These gorgeous crystals can then be treasured and stored by kids that have their own special rock and gem collection. They will learn all about STEM minerals while adding some beautiful pieces to their bedroom. This is a safe game with minimal mess.
