The most interesting parts of our world are often the ones you can't see. What if you could cut open a jet engine, a skyscraper, a subway tunnel, or a data center-and watch it work from the inside?
CUT OPEN! takes curious kids inside 40 real machines, buildings, hidden city systems, and modern technologies. Every spectacular cutaway reveals more than just the parts: it shows where they are, what they do, and how they work together as one functioning system.
Follow air as it races through an engine. See the machinery that moves an elevator. Travel beneath the street through tunnels, pipes, power systems, and hidden infrastructure. Discover the structures, chambers, motors, cables, safety systems, and technology normally sealed behind metal, concrete, walls, and pavement.
