What could be more exciting than digging in the earth and finding treasures? If your child can't get enough of excavations and the wonders of geology, the KidzLab crystal excavation set is just the thing for your little spelunker. And the crystal excavation really has it all. A total of eight crystals are enclosed in a beautifully decorated plaster block, which your mini hobby geologist must carefully remove from the rock with the included excavation tool. Equipped with a magnifying glass and brush, your little explorer can learn everything about the crystals he finds and tell you afterwards exactly what the natural treasures are all about.
