An amazing Earth Day at Technical University of Košice, which we celebrated on April 22, 2026, together with children from primary schools.

Last week, we took part in Earth Day at Technikom Košice, where children had the opportunity to enjoy a variety of activities such as painting stones, attending a short talk about minerals and their everyday use, and exploring mineral properties like fluorescence and reactions to UV light, which they really enjoyed. At the end, they could take home their own hand-painted stone.
