1. Content:
This exhibition mainly consists of two hollow balls and one air outlet. Two hollow balls separated by a certain distance are suspended on a stainless steel bracket. An air outlet is set below the balls, facing directly between them, and a fan is installed inside. The audience presses the start button, and the fan starts running. At this point, observing the change in distance between the two small balls will reveal that they separate due to the wind blowing between them? The answer is actually negative. The exhibition items clearly demonstrate the Bernoulli effect, allowing the audience to understand the scientific principles of the Bernoulli effect in a vivid way.
2. Principle:
The principle of ball suction
This exhibition consists of two suspended hollow balls and an air outlet. When the button is pressed, airflow will pass through the gap between the two hollow balls. At this point, it was found that the two balls not only did not separate outward, but also attracted inward and collided with each other. This phenomenon confirms Bernoulli's law: when the airflow velocity between two hollow spheres increases, the air pressure in the middle is lower, and the high air pressure on the outer side presses the hollow spheres towards the middle.
When waiting for the subway or train, there is a yellow line on the platform, and the staff will constantly remind us not to cross the yellow line. Why is this? The reason is that when the train enters the platform at high speed, the velocity of the airflow in front of us will increase, resulting in a decrease in air pressure, while the normal air pressure behind us will push us towards the train, causing danger. The principle in fluid mechanics, known as Bernoulli's law, is that as the velocity of the airflow increases, the air pressure decreases.
3. Purpose:
The exhibition items feature a simple interactive device that adjusts the distance between two balls in the airflow by rotating the wheel, exploring the laws of ball suction and understanding the meaning of Bernoulli's theorem.
