While frequently attributed solely to , the full explanation involves several interacting physical concepts:
: According to the NASA Bernoulli's Principle guide , when air moves more quickly over a curved surface (like the top of the paper), the air pressure decreases. The relatively higher atmospheric pressure underneath then pushes the paper upward. air flow
When you blow air across the top of a curved sheet of paper, the paper rises . This phenomenon is a classic physics demonstration often used to illustrate fluid dynamics and the generation of lift. The Physics of Airflow and Paper While frequently attributed solely to , the full
