I have a kindergarten on the floor below my apartment and the kids were throwing things at the pipes going up the entire column of apartments

I was pondering if it would be funny to tap the pipes and hear them freak out, but then I realised the kids wont understand how sound transmits through a pipe. 🤔 In their imagination they'll probably think it's a spirit or monster, or whatever they saw on cartoon network that day. 🤣 Then they'll tell all their friends and inevitably tap on the pipes every single day for the rest of my time here and I'll end up ruining everyones lives on the floors above me. 😭

okay i wont do it... yet 👀
