@mlm.ai: 有人买了一个看起来完全没用的小装置,装在门上本来只是图个好玩。 结果没想到,一只啄木鸟只要轻轻一拉下面的那根线,整个装置就会疯狂触发——门被敲得震天响,像是有人在拼命砸门。 动静之大,连邻居都以为是在开枪,差点报警。 一个“没用的发明”,却变成了全小区最吵的存在。 Someone bought a seemingly useless little gadget and installed it on their door just for fun. But unexpectedly, whenever a woodpecker pulls the string underneath, the whole mechanism goes wild—pounding on the door with explosive force, as if someone is aggressively knocking nonstop. The noise is so intense that neighbors thought it sounded like gunshots and almost called the police. What was meant to be a pointless invention suddenly became the loudest thing in the neighborhood.
