Science Behind It
There is a famous Bernoulli's law in fluid mechanics: the faster the air flows, the lower the pressure. There is a fan under the booth. Press the "start" button, and the fan will blow upwards along the vertical pipe on the right. The air in the vertical pipe flows quickly, and the pressure decreases. However, the external air pressure is normal, forming a pressure difference. The air will flow from the high-pressure position to the low-pressure position, so the air will be continuously "sucked" into the vertical pipe along the C-shaped pipe. The small ball follows the movement of the airflow and runs in circles along the C-shaped tube, repeating the cycle. We have to stand outside the safety yellow line when waiting for the train, stay away from large cars when overtaking on the highway, or soccer players can play beautiful "banana balls" and table tennis players can play beautiful "arc spinning balls", all of which demonstrate the effectiveness of Bernoulli's principle.
Dimensions

Product structure: Designed with a science museum booth. The booth is made of 1.2mm galvanized steel plate, and the tabletop is made of 12mm anti PET plate. The internal carbon steel and damping shock pads are reserved, and heat dissipation holes are reserved. It is equipped with leakage protection device, and the modular design is convenient for later maintenance. All sheet metal components are treated with electrostatic spraying technology.
