Electronic bubblewrap toy

Japanese toymaker Bandai's Mugen Puchi-Puchi is a handheld electronic gizmo that makes the sound of popping bubblewrap when you press on the plastic bubbles.  For courtesy, the manufacturer claims the sound is automatically turned off when the toy is used on the train. (?)
