An air bladder fills with air and raises the weaer's arm, pressurized by constant head nodding. Head shaking releases air lowering the arm. The inflation pump is located under the chin disguised as a neck beard or oversized bow tie. The deflation valve is opened and closed by the quarter rotation of the head.

Annotation:







       Brilliant. The vigorous nodding conveys the impression of understanding, so the professor is more likely to call on you so as to hear your insightful question.
