在桌面上摆两个乒乓球，然后，用一根吸管往两球中间吹气，结果两乒乓球居然相互吸引而靠在一起。这是为什么芽原因是：两球间空气压力突然减弱了，比乒乓球外侧的空气压力小得多，因此，空气压力不断地把两个乒乓球向压力较小的地方推，所以两个乒乓球自然地往中央靠拢。再做? Put two table tennis balls on the tabletop, and then use a straw to inflate the two balls, resulting in the two table tennis balls actually attracting each other and leaning together. This is why the buds are: the air pressure suddenly weakened between the two balls, much less than the air pressure outside the ping pong ball, so the air pressure constantly pushes the two ping pong balls toward the less stressed part, so two ping pong The ball naturally moves closer to the center. Do it again?
