The suspension blow ball is a classic toy for the post-80s nostalgia experiment. The magic is that the ball can be suspended in the air and won't fall down. It can also be blown obliquely. With a slight tilt at a certain angle, the ball can still be suspended in the air. And you can operate.
Principle of Bernoulli's theorem: From the incompressible Bernoulli Theorem, when the ideal fluid flows along a steady state, the flow velocity increases, the static pressure of the fluid decreases; on the contrary, the flow velocity decreases, and the static pressure of the fluid increases, but the sum of the static pressure and the dynamic pressure of the fluid is always the same, which is the basis of the takeoff principle of aircraft.
