An interesting family lives in our house, on the same landing with me. Dad and mom are volcanologists, they study volcanoes. Their daughter Irishka is in first grade, and her son Len goes to kindergarten, in the older group. Last year, the parents went on an expedition. Their cousin Tanya, who is studying at the conservatory, remained with Lyonya and Irishkoi. Children like it with Tanya: she is cheerful and always comes up with new games. These games are not only interesting, but also scientific, and scientific games are not often found. So I decided to write a book about these games so that you learn about why the record sings, how to make a thermometer out of a bottle, why the ship needs sails... These and many other questions are answered by the science of physics, the first steps into which you will take by reading the book "Physics for Kids."
