Bernoulli Suction Cup - Customized Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:
Operating instructions: Press the "Start" button and try to lift different shaped discs and place them against the air outlet of the suction cup. Observe if all discs can be lifted and suspended in the air? Function Overview: Exhibition items consist of fans, air supply ducts, and various test panels. The audience presses the "start" button and tries to lift different shaped discs against the air outlet of the suction cup. After releasing it, they will find that some discs are sucked in and cannot fall off. Scientific principle: Why does the phenomenon of being sucked up and suspended in the air occur? We all have this experience: when waiting for the subway or train, we may find 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.
