Blow the Ball from Afar
Exhibit Dimensions: Transport dimensions: 540×440×640mm, Display dimensions: 540×440×1450mm. Exhibit Composition: Consists of ABS plastic molded cabinet, ABS plastic molded pedestal, ABS milky white plastic molded operation countertop with color silk-screen flip-up instruction board, delay circuit, stainless steel illuminated self-reset metal button, leakage protector, square prism, cylinder, triangular prism, multiple small balls, and air nozzle, etc. Blow air at the cylinder, low pressure is generated behind the cylinder, the surrounding air tries to balance the low pressure, and the small balls are blown by the airflow. However, when blowing at the square prism or triangular prism, the air cannot reach behind the square prism, so the small balls will not be blown. Through the comparison of three experiments with cylinder, square prism, and triangular prism, the exhibit demonstrates the influence of obstacles of different shapes on airflow, thereby introducing Bernoulli's principle.
