Geology you can touch and understand. In this excavation set from Kosmos, children use a hammer and chisel to search for colorful and fascinating treasures of nature. Hammering, scraping, digging - they work their way through the soft gypsum block layer by layer, revealing various colorful minerals such as rock crystal, rose quartz, amethyst, aventurine, and red jasper. The clear and illustrated instructions show exactly how to proceed. Just like professionals in research, children clean and document their finds, allowing them to display them in their room. Of course, there are also additional information about minerals and stones included in the booklet, and those looking for a nice storage solution for their new treasures will find it here as well.
