Using the see-through magic lens, you can learn about mathematics, physics, chemistry, and engineering by exploring the inner workings of machines.

In your kitchen or bedroom, beneath city streets, or far up in space, machines are at work day and night making, moving, building, and even thinking for us. In this eye-catching book, you can explore the hidden inner workings of machines and inventions: from everyday objects like toasters and bicycles, to cutting-edge technologies such as pill-sized medical robots and super-fast trains. The see-through magic lens will reveal how all these machines work, showing all the elements hidden within them - from wires and pipes, to magnetic and gravitational forces.
