Bernoulli’s principle describes how a fluid moves faster when it passes through a narrow space, causing the pressure in that area to drop. When a stream of compressed air is directed around a screwdriver, the moving air creates a region of lower pressure compared to the still air around it. This pressure difference produces lift, allowing the screwdriver to rise and stabilize as if it is floating. It is a simple but powerful demonstration of how fluid motion shapes the forces we observe. This sa
