the audio shaker looks similar to a fat thermous with a cord attached. what you do is remove the lid and say something into it. it then records the sound and then you put the lid back on. if you shake it you hear the recorded noise but in a jumbled up manner. the faster you shake it the more high pitch the noise is and it is even more jumbled up. if you remove the lid and turn it over you hear the noise one last time as it “pours” out.
