The ball is suspended in the air using Bernoulli's principle. Bernoulli's principle describes the relationship between the pressure and the velocity of a moving fluid (i.e., air or water ). Bernoulli's principle states that as the velocity of fluid flow increases, the pressure exerted by that fluid decreases.
