Bernoulli Suction Cup
Operation: Press the "Start" button, try to lift different shaped discs against the suction cup's air outlet, and observe whether all discs can be sucked up and suspended in the air? Function Overview: The exhibit consists of a fan, air duct, and various test discs. Visitors press the "Start" button, try to lift different shaped discs against the suction cup's air outlet, and after releasing, they will find that some discs are sucked 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 a subway or train, we notice a yellow line on the platform, and staff constantly remind us not to cross the yellow line. Why is this? The reason is that when a train enters the station at high speed, the airflow in front of us increases in velocity, causing a decrease in air pressure, while the normal air pressure behind us pushes us toward the train, creating danger. When the airflow velocity increases, the air pressure decreases. This principle in fluid mechanics is the famous Bernoulli's principle.
