Prof. Walter Lewin, the famous MIT physicist, often demonstrated Bernoulli’s Principle in his engaging lectures. Bernoulli’s Principle states that as the speed of a fluid increases, its pressure decreases. In his demonstrations, Lewin used simple yet striking experiments—such as blowing between suspended objects or directing airflow over a sheet of paper—to show how faster-moving air creates lower pressure, causing objects to move together or lift. His style of teaching made abstract physics con

MIT Physics | Walter Lewin: The Electric Shield (Faraday Cage) Witness one of the most electrifying demonstrations in physics as Professor Walter Lewin steps inside a wire mesh cage and subjects himself to hundreds of thousands of volts. This unforgettable lecture illustrates the powerful concept of electric shielding, or the Faraday cage effect. Discover the fundamental principle of electrostatics that explains why the electric charge resides exclusively on the outer surface of a conductor, lea
