FerienKinderUni: "Paper and magic ink research workshop" at the tropical greenhouse in Witzenhausen

Even the ancient Egyptians made papyri and Harry Potter could read magical inks! We look at plant-based raw materials and create our own paper. We write with secret inks made from lemons, apples and onions! And we'll find out why and how it all works!

A cooperation project between the Tropical Greenhouse, University of Kassel and Bildung trifft Entwicklung, Göttingen, Bildungszentrum WeltGarten.
