The Stickmen are back... taking a slice through the Earth to show what happens, and what exists, at all levels everywhere:

through layers of atmosphere that wrap around the globe; from mountaintops and live volcano craters down to the molten core; from the ocean's sunlight zone to the deepest trench in the seabed;

and from the rooftop of the tallest skyscraper to the foundations of a city and its maze of underground tunnels.

With a little dusting of of Stickmen humour it's great for reluctant readers too!
