Ravensburger Play, listen, marvel: Vehicles. A sound playbook without batteries and electronics

What's rattling here? Vehicles make many different sounds. Drive the tractor bumpy across the fields, slam the door of the moving truck with a loud bang, and raise the folding roof of the camper with a buzzing sound. In this innovative sound playbook, vehicle noises can be created simply by moving easy-to-slide elements. If the slider is moved quickly, the sound is different than when moved slowly. No batteries are required. The books in the "Play, Listen, Wonder" series are special sound books: they operate entirely without electronics or batteries, as various sounds can be produced solely through the movement of sliding elements on the pages. Even small children's hands can move the sliders. This guarantees endless sound play fun for children aged 2 and up!.
