Static Ping-Pong
★Exhibit Content: Static Electricity Characteristics ★Interaction: Electromechanical Interaction ★Operation: Press the "Start" button to see the ball swing back and forth. ★Exhibit Description: This exhibit consists of a display stand, an instruction sign, an electrostatic generator, metal balls, a protective cover, etc., demonstrating electrostatic phenomena. When the visitor presses the start button to activate the exhibit, they will see the suspended ball moving back and forth between two fixed balls. ★Scientific Principle: How does the ball keep bumping back and forth? This exhibit demonstrates the basic characteristics of static electricity—like charges repel, opposite charges attract. The electrostatic generator produces high-voltage static electricity. Due to electrostatic induction, the suspended metal ball becomes charged. When the charge accumulates to a certain level, the charged plates interact with the metal ball, first attracting opposite charges. At this time, the metal ball is attracted to the plate, the charges neutralize and release, the metal ball is then induced with a charge that repels the charge on the other plate, and the metal ball is pushed away. Thus the metal ball swings left and right, producing a ping-pong sound. When the power switch is turned on, the two paddles carry high-voltage positive and negative charges respectively. Assume: the ball, pulled by the starting device, collides with the positively charged paddle and acquires a positive charge (the starting device resets); due to the collision, the ball carries the same charge as that paddle, repels it, and is attracted to the opposite paddle carrying the opposite charge, then collides with it. During the collision, it releases its charge and acquires the same charge as that paddle, repelling it and being attracted to the opposite paddle—thus the ball swings back and forth between the two paddles, producing a ping-pong sound. After the power is turned off, the capacitor in the circuit still holds some charge, and the ball has inertia, so it will continue to swing for a while until the capacitor's charge is neutralized to the point where it can no longer pull the ball, and then it stops at the equilibrium position.
