The mega accordion flip book with a span of 2.5 meters. Join us on a journey through the layers of the Earth to the Earth's core and back to the surface! Along the way, you'll see the most amazing and interesting things! This almost endless accordion picture book draws attention to what we often walk over carelessly: the ground beneath our feet. What is actually beneath the surface of our streets, meadows, and fields? Water pipes, cable ducts, sewage pipes, layers of humus with many insects, riverbeds... Deeper and deeper we go into the underworld through rocks, minerals, and magma until we reach the molten hot Earth's core - and back again.
