The people of laputa use flappers and bladder to their attention .this device was designed because the masters remained preoccupied with their thoughts and they could neither speak or listen to other.

If a bladder was struck on mouth it means master was to speak,if bladder was struck on ear it meant master was to hear something and an occasional flap  on masters eye meant that there are some hurdles on the way and he must walk carefully.
