Bernoulli's principle

The explanation for this phenomenon is rooted in Bernoulli's principle, which suggests that swift-moving air results in reduced pressure. To demonstrate this, a device was employed to generate rapid air movement, thereby creating high pressure within the window and low pressure outside. As fluids typically move from areas of higher to lower pressure, the air present within the window swiftly exited. By eliminating the air supply necessary for combustion, the fire was extinguished through the application of Bernoulli's principle.
