The mega accordion fold picture 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 will see the most astonishing 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, humus layers teeming with insects, riverbeds... Deeper and deeper we go into the underworld through rocks, minerals, and magma until we reach the searing hot core of the Earth - and then back again.
