Named after Daniel Bernoulli, Bernoulli’s principle describes the relationship between pressure, density and incompressible flow speed. Although Bernoulli was mainly involved with hydrodynamics, his invention is a method that can also be used in aerodynamics. For example, Bernoulli’s principle offers one way of calculating aerodynamic lift to make planes fly. Your task in testing Bernoulli’s principle is to use air cannons to keep a ball in the air. For that, you’ll need to move the air cannons and direct the air flow. There are also rings suspended in mid-air, through which you have to steer the ball carefully. You will score points for each ring you pass through.
