Exhibition description and introduction of scientific principles:
The exhibition items have two sets of connected acrylic pipes, one is a thick pipe and the other is a narrow pipe. There is a spherical ball that can be pulled up and down in the thick tube, and a lightweight ball inside the narrow tube. The narrow tube is equipped with a funnel-shaped protective net and a layer of barrier net. When participating, participants pull the rope to lift the ball in the thick tube to a high place. Release the rope, the ball quickly falls down, and the air pressure inside the tube instantly increases. The air is forced into the narrow tube, pushing the ball upwards and ejecting it. Shanghai Inertia reminds everyone that when the ball hits the barrier, it will fall back into the narrow tube along the funnel-shaped protective net.
