In his famous lecture demos, he blows air between hanging objects (like balloons or paper strips), and instead of moving apart, they come together. This happens because the air moving quickly between them lowers the pressure there, while the higher surrounding air pressure pushes them inward—clearly illustrating Bernoulli’s principle in action."
