How everything works. Great journey to the world of ordinary things

How surprisingly difficult and interesting is everything around us: Internet and cellular communications, electricity and sewage, processing of garbage and the energy of the sun!
This book is your guide in the world of useful inventions, modern technologies and "smart" mechanisms.
Consider the familiar objects and devices in the smallest details on huge folding pages and understand all the intricacies of complex processes - from pizza baking to water cleaning and starting the satellite.
Find out why it is cold in the refrigerator, where the toaster knows that the bread is fried, which cars have fists and a drum, why a doorbell is a hammer, and a drain tank of a float.
Find out how you use photocells, satellite signals, alternating current and magnetic field every day.
Rather, open the book - the journey begins!
For children 8-12 years old
