After a recent earthquake, Walter Powell asks Charles to teach the Powell children emergency procedures to prepare them for the next quake. Charles discovers that an emergency drill is not realistic enough, so he invents a device to help people practice for a real quake -- a battery-operated belt that shakes your body, called the 'Quake-Maker.'
