3. Tell the story of sound levels heard throughout the day.

Slowly and gently brushing the pipe cleaners is a low-level sound, and they sway back and forth without bending (morning conversation).

Moderate brushing at a slightly faster pace with your hand should bend the pipe cleaners only slightly, where they bounce back to the starting position pretty well (lawn mower).

Brushing with a much stronger force at a rapid pace should bend the all the pipe cleaners permanently (fireworks show). When the hair bundle rocks back and forth that is what creates the signal to the brain.

REMINDER: Be sure to connect the visual image of the healthy hair bundle to the straight pipe cleaners at the start of the story and the damaged hair bundle image looks just like the bent pipe cleaners at the end of the story.
