Riddles of electricity (1926)

Why does lightning beat in one place, but does not fall into another? How to understand the watermelon and apple with an electric law? Is it possible to boil cold water with two knives and wires? And how to build an alternating current generator from improvised objects? The book contains dozens of curious physical tasks, paradoxes and riddles about electricity. All of them are built in the format of discussion: the reader sees the question and monitors a small but capacious reasoning leading to the correct answer. The book is written in an accessible language, and for greater clarity, detailed schemes and tables are placed in it, as well as visual illustrations.
The publication is intended for children interested in physics, and for parents who are engaged with them on their own. It will also be useful to teachers when organizing and conducting school lessons
