With the Buki excavation set, young researchers discover the diversity of geology. The included excavation block contains seven real rocks and minerals to be unearthed using a hammer and chisel. A practical tray ensures clean work at the table, while the brush and magnifying glass allow for detailed uncovering and examination of the finds. Step by step, the hidden rock types such as amethyst or citrine are revealed and subsequently identified. The set combines hands-on work with the joy of scientific discovery.
